Yuri's dad needs to fertilize the grass in the yard. The back yard measures 55 feet by 30 feet, while the front yard is a square with a length of 42 feet on each side

The answer of the given question based on the finding the value of x and y and measuring the angle ∠DFE the answer is  x = 11.8 and y = -8 and angle ∠DFE is 88° degrees.

A triangle is  geometric shape that is formed by three straight line segments that connect three non-collinear points in plane. These points are called vertices of triangle, and  line segments are called sides. The triangle is one of  most fundamental shapes in mathematics and has many interesting properties that make it useful in variety of applications.

Triangles can be classified based on  lengths of their sides and  measures of their angles. If all three sides of  triangle are of equal length, it is called  equilateral triangle. If two sides of  triangle are of equal length, it is called  isosceles triangle. If all three sides have different lengths, it is called  scalene triangle

In triangle DEF, we know that the sum of the angles is 180° degrees, so:

∠DEF + ∠DFE + ∠EFD = 180°

Substituting the given values, we have:

92° + (5x - 7) + 36° = 180°

Simplifying the equation, we get:

5x + 121 = 180

5x = 59

x = 11.8

Now we know x, then we can find y:

y = 180 - 92 - 36 - (5x - 7) = 45 - 5x

y = 45 - 5(11.8) = -8

Therefore, x = 11.8 and y = -8.

To find the measure of ∠DFE, we can use the fact that the sum of the angles in a straight line is 180 degrees. ∠DFE is opposite to angle D, which is 92°, so:

∠DFE = 180° - 92° = 88°

Thus, the measure of ∠DFE is 88° degrees.

From the given data of Nicole's wedding organization, 18 tables at the venue is sufficient for the total 145 arriving guest.

To determine whether there are enough tables for the guests, we need to calculate the total circumference required for all the guests and compare it to the total circumference of the available tables. The circumference of a circle is given by the formula C = πd, where C is the circumference, d is the diameter, and π is the constant pi, approximately equal to 3.14.

For the circular table with a diameter of 180cm, the circumference is:

C = πd

= π x 180cm                              

= 565.2cm

Each guest needs 7cm around the circumference of the table, so the total circumference required for one guest is 7cm.

For 145 guests, the total circumference required is:

Total circumference required

= 145 guests x 7cm per guest

= 1015cm

Now, we can calculate the total circumference of all the tables available:

Total circumference of all tables

= 18 tables x 565.2cm per table

= 10,174.4cm

Since the total circumference required for the guests (1015cm) is less than the total circumference of all the available tables (10,174.4cm), we can conclude that there are enough tables for the guests. Therefore, there are enough tables at the venue for the 145 guests.

The growth constant is 0.69 and the population will increase to 12900 after approximately 3.7 years.

We have, Sunset Lake is stocked with 2500 rainbow trout and after 1 year the population has grown to 7050. Assuming logistic growth with a carrying capacity of 25000,

The logistic growth model is given by the equation

dN/dt=rN[(K-N)/K]

where, dN/dt = rate of change of population with respect to time,

N = population size at time t,

r = intrinsic rate of natural increase (growth constant),

K = carrying capacity.

The population size, "N" after 1 year = 7050

The initial population, "N₀" = 2500

The carrying capacity, K = 25000

We can use the following formula to find the value of the growth constant,

r = 2.303/t{ln(N_t/N₀) }........... (1)

Where, t = time taken for the population to increase from N_0 to N_t= 1 year (given)

Substituting the given values in equation (1), we get

r = 2.303/1 ln(7050/2500) ⇒ 0.688 ≈ 0.69

The value of the growth constant is 0.69.

Now, we can use the logistic growth equation to find the time required for the population to reach 12900.

dN/dt=rN[(K-N)/K]

Given, N₀ = 2500 and K = 25000

Differentiating both sides with respect to t,

dN/dt = rN[(K-N)/K] + Ndr/dt

Substituting the values of N, r, and K in the above equation, we get,

dN/dt= 0.69N[(25000-N)/25000] + N{dN/dt}

Let the population N become 12900 at time t = t₁

Therefore, at time t = 0, the population N₀ = 2500

Also, at time t = 1, the population N₁ = 7050

Substituting these values in the above equation, we get,

dN/dt= 0.69N[(25000-N)/25000] + N₁

dN/dt= 0.69(2500)[(25000-2500)/25000] + N₁

Solving for N₁, we get, N₁ = 7825

Substituting N₁ = 7825 in the above equation,

dN/dt= 0.69(7825)[(25000-7825)/25000] + N₁

dN/dt= 3263.25/1.69 ⇒ 1930.4

Now, to find t1, we can use the following formula;

ln[(K-N₁)/(K-N₀)] = rt₁

Substituting the given values, we get,

ln[(25000-12900)/(25000-2500)] = 0.69t₁

On solving for t₁, we get;

t₁ = ln[(1575/22500)]/0.69 ≈ 3.7 years

Hence, the population will increase to 12900 after approximately 3.7 years.

Answer:

To compare the kicks, we need to determine which kick goes the farthest and/or highest. Let's analyze each kick one by one.

Stewart's kick:

Starting 12 yards out from the goal, Stewart's kick reaches a maximum height of 17 yards and lands 48 yards from the goal. We can assume that the ball lands at the same height as it was kicked. Therefore, the horizontal distance traveled by the ball is:

d = 48 - 12 = 36 yards

The total distance traveled by the ball is the hypotenuse of a right triangle with legs of 36 and 17 yards. Using the Pythagorean theorem, we can find the distance traveled by Stewart's kick:

distance = sqrt(36^2 + 17^2) ≈ 40.48 yards

Oswaldo's kick:

According to the equation given, the height of the ball (in yards) at any horizontal distance (in yards) from the goal is given by:

y = -x^2 + 14x - 24

We want to find the maximum height reached by the ball, so we need to find the vertex of the parabolic path. The x-coordinate of the vertex is given by:

x = -b / 2a = -14 / (-2) = 7

The maximum height is the y-coordinate of the vertex:

y = -(7)^2 + 14(7) - 24 = 25

Therefore, Oswaldo's kick reaches a maximum height of 25 yards.

To find the horizontal distance traveled by the ball, we need to find the x-intercepts of the parabolic path. Setting y = 0, we get:

0 = -x^2 + 14x - 24

Solving for x using the quadratic formula, we get:

x = (14 ± sqrt(14^2 - 4(-1)(-24))) / (2(-1)) ≈ 2.63, 11.37

Therefore, the ball lands at a horizontal distance of approximately 2.63 or 11.37 yards from the goal. The total distance traveled by the ball is the sum of the horizontal distance and the maximum height:

distance = 11.37 + 25 ≈ 36.37 yards

Kevin's kick:

We don't have the equation or data for Kevin's kick, so we can't determine the maximum height or the total distance traveled by the ball.

Flynn's kick:

We have a partial table of data points for Flynn's kick. We can plot the points on a graph and draw a curve that fits the data points. Here is the graph:

Flynn's Kick

The curve appears to be a parabolic path, so we can assume that the equation for the path is:

y = ax^2 + bx + c

To find the coefficients a, b, and c, we need to solve a system of equations using three data points. Let's use the data points (12, 8.75), (15, 17.2), and (18, 19.7).

Using the first data point, we get:

8.75 = a(12)^2 + b(12) + c

Using the second data point, we get:

17.2 = a(15)^2 + b(15) + c

Using the third data point, we get:

19.7 = a(18)^2 + b(18) + c

Solving this system of equations using a calculator or matrix methods, we get:

a ≈ 0.0571

b ≈ -1.

1 hot dog costs amount $8.00 and 1 hamburger costs $10.80.

Steve needs to buy meat for a barbecue and he bought 15 hot dogs and 13 hamburgers for amount $192. He realized that he didn't buy enough so he bought 75 hot dogs and 45 hamburgers for $780. To calculate the cost of 1 hot dog or 1 hamburger, we need to divide the total cost of each item by the amount purchased. For the hot dogs, we divide $780 by 75, which gives us $8.00. For the hamburgers, we divide $780 by 45, which gives us $10.80. Therefore, the cost of 1 hot dog or 1 hamburger is $8.00 and $10.80 respectively.

Hot Dogs :  ($192 + $780) / (15 + 75) = $8.00

The number of guests at a theme park can be modeled by the function p(t), where t is measured in hours and p is the number of guests. The function p(t) is a solution to the logistic differential equation.

The formula for logistic differential equation is dp/dt = p/3 - p^2/60000. This equation models the rate of change of the number of guests at the theme park over time.

To find the solution to this equation, we can use separation of variables. First, we can rearrange the equation to get:

dp/(p/3 - p^2/60000) = dt

Next, we can integrate both sides of the equation to get:

∫dp/(p/3 - p^2/60000) = ∫dt

Using partial fraction decomposition, we can rewrite the integral on the left-hand side of the equation as:

∫(3/60000)/(1 - 3p/60000)dp = ∫dt

Integrating both sides of the equation gives us:

-20000ln|1 - 3p/60000| = t + C

Solving for p gives us:

1 - 3p/60000 = Ce^(-t/20000)

3p/60000 = 1 - Ce^(-t/20000)

p(t) = 20000 - (20000C)e^(-t/20000)

To find the value of C, we can use the initial condition p(0) = p0:

p0 = 20000 - 20000C

C = (20000 - p0)/20000

Substituting this value of C back into the equation for p(t) gives us the solution:

p(t) = 20000 - (20000 - p0)e^(-t/20000)

This is the solution to the logistic differential equation that models the number of guests at a theme park over time.

A rate in arithmetic is a ratio that contrasts two separate values with various unit systems. For instance, if John types 50 words per minute, that means he types 50 words per minute. We are dealing with a rate because the word "per" is there. The symbol "/" can be used in place of the word "per" in issues.

When two or more similar amounts or numbers are being compared using the same units, a ratio is utilized. When referring to the ratio of one quantity "to" the second quantity in spoken language, it is frequently written with a colon.

First, we convert the gas price from liters to gallons. One liter is equal to 0.264172 gallons, so:

$1.54 per liter = $1.54 / 0.264172 gallons = $5.82 per gallon

Next, we need to calculate how many gallons of gas are needed to drive 225 miles. If the car gets 29 miles per gallon, we can calculate the gallons of gas needed as:

225 miles / 29 miles per gallon = 7.7586 gallons

Finally, we can calculate the total cost of gas as:

Total cost = gallons of gas needed x gas price per gallon

Total cost = 7.7586 gallons x $5.82 per gallon

Total cost = $45.14

Therefore, it would cost approximately $45.14 to drive 225 miles in a rental car that gets 29 miles per gallon, assuming a gas price of $1.54 per liter in France.

1. A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. 2. The point where a graph contacts the y-axis is known as the y intercept.

The graph's intersection with the y-axis is known as the y-intercept. Finding the intercepts for any function with the formula y = f(x) is crucial when graphing the function. An intercept can be one of two different forms for a function. The x-intercept and the y-intercept are what they are. A function's intercept is the location on the axis where the function's graph crosses it.

The simplified fοrm οf the square rοοt οf 7 divided by 20 is:

(7 + 2√(35)) / (20 * (√(7) + 2√(5))).

Equivalent expressiοns are expressiοns that wοrk the same even thοugh they lοοk different. If twο algebraic expressiοns are equivalent, then the twο expressiοns have the same value when we plug in the same value fοr the variable.

Tο simplify the square rοοt οf 7 divided by 20, we can ratiοnalize the denοminatοr by multiplying the numeratοr and denοminatοr by the cοnjugate οf the denοminatοr, which is √(7) + 2√(5):

(√(7)) / 20 = (√(7) / 20) * (√(7) + 2√(5)) / (√(7) + 2√(5))

Expanding the numeratοr using the distributive prοperty gives:

(√(7) * √(7) + √(7) * 2√(5)) / (20 * (√(7) + 2√(5)))

Simplifying the numeratοr gives:

(7 + 2√(35)) / (20 * (√(7) + 2√(5)))

Step-by-step explanation:

To find the minimum height of the satellite during the given time period, we need to find the vertex of the parabolic function f(x) = 2x^2 - 16x + 800.

The vertex of a parabola with equation f(x) = ax^2 + bx + c is given by the formula:

x = -b / 2a and f(x) = -b^2 / 4a + c

In this case, a = 2, b = -16, and c = 800. Substituting these values into the formula, we get:

x = -(-16) / 2(2) = 4

f(x) = -(-16)^2 / 4(2) + 800 = 848

Therefore, the minimum height of the satellite during the given time period is 848 kilometers, and it occurs after 4 hours of flight time.

Answer:

The given expression is:

-(1)/(9)(13x)

We can use the commutative property of multiplication to rearrange the order of the factors:

-(1)/(13x)(9)

Now, we can use the associative property of multiplication to group the factors in any way we want:

-(1/13)(1/x)(1/9)

This is the simplified expression using the commutative and associative properties of multiplication.

4 + 7×6 = 4 + 42 = 46

12 + 9×3 - 1 = 12 + 27 - 1 =39 - 1 = 38

If Mary leaves a campsite and walks 4 miles east and 2 miles south and  Her friend walks 3 miles north and 1 mile west then Mary and her friend are approximately 5.83 miles apart.

We can use the Pythagorean theorem to find the distance between Mary and her friend. We'll need to create a right-angled triangle with the two walks forming the legs of the triangle.

Mary walks 4 miles east and 2 miles south, so she moves 4 units to the right (east) and 2 units down (south).

Her friend walks 3 miles north and 1 mile west, so she moves 3 units up (north) and 1 unit to the left (west).

We can see that the two walks form a right-angled triangle. The distance between Mary and her friend is the hypotenuse of this triangle.

Let's calculate the length of each leg of the triangle:

The length of the horizontal leg is 4 - 1 = 3 miles (Mary moves 4 miles to the right and her friend moves 1 mile to the left).

The length of the vertical leg is 2 + 3 = 5 miles (Mary moves 2 miles down and her friend moves 3 miles up).

Now, we can use the Pythagorean theorem:

distance² = 3² + 5²

distance² = 9 + 25

distance² = 34

distance = √(34)

≈ 5.83 miles

Therefore, Mary and her friend are approximately 5.83 miles apart.
