Answer:

Here, given

present population = 20000

according to question,

population gets double every 34 years

i.e P = 20000 × 2

= 40000

now,

P = 40000

T = 68-34 = 34

ie, again p is double

so, P = 40000×2

= 80000

Hence, the population after 68 years from now is 80000

The correct option is (a) ŷ = -1.34x+21.5 , that is the best model to fit the scatter plot.

A scatter plot (or scatter chart, scatter graph) uses dots to represent values for two(2) different numeric variables. The position of each dot on horizontal and vertical axis indicates values for an individual data point.

The model of the equation best for the plot is,

ŷ = -1.34x+21.5

At point (1,20),

ŷ  = -1.34x+21.5

20 = (-1.34 ×  1) + 21.5

20 ≈ 20.15

At point (3,19),

ŷ = -1.34x+21.5

19 = (-1.34 × 3) + 21.5

19 ≈17.45

At point (5,15),

ŷ = -1.34x+21.5

15 = (-1.34 × 5) + 21.5

15 ≈ 14.75

The model ŷ = -1.34x+21.5   is giving the best estimation.

The equation of the hyperbola with the given foci and vertices is (x - 3)² - (y - 1)² = 64

Hyperbola is a type of conic section, which is a curve formed by the intersection of a cone with a plane. It is similar to a circle, but with two separate halves that are mirror images of each other. These two halves are called branches, and the point where they intersect is the vertex. The hyperbola is characterized by its two foci, which are points that lie on the inside of the structure.

The equation of a hyperbola with foci (h, k) and (h, l) and vertices (m, n) and (p, n) is given by:
((x - h)² / (m - h)²) - ((y - n)² / (k - n)²) = 1
In this case, h = 3, k = 11, l = -9, m = 11, and n = 1. Plugging these values into the equation, we get:
((x - 3)² / (11 - 3)²) - ((y - 1)² / (11 - 1)²) = 1
Simplifying, we get:
(x - 3)² - (y - 1)² = 8²
Therefore, the equation of the hyperbola with the given foci and vertices is: (x - 3)² - (y - 1)² = 64.

Answer:

Base=20m   height= 15m

Step-by-step explanation:

The area of a triangle is given by:

[tex]A=\frac{bh}{2}[/tex]

since base is 10 less than twice the height  b=2h-10

plugin in those values and knowing area is 150
[tex]150=[/tex][tex]\frac{h(2h-10)}{2}[/tex]

then solve for h

[tex]300=2h^2-10h[/tex] this is quadratic equation

[tex]h^2-5h-150=0[/tex]  
factorizing  (notice you can also use quadratic equation)

[tex](h-15)(h+10)=0[/tex]
which positive solution (height cant be negative) is h=15
then the base is b=2(15)-10=20

Answer:

The height is 15 meters and the base is 20 meters.

Step-by-step explanation:

Let's use the formula for the area of a right triangle:

A = (1/2)bh

Where A is the area, b is the base, and h is the height.

We're given that the area is 150 square meters, so we can substitute that in:

150 = (1/2)bh

Next, we're told that the base is 10 less than twice the height. In other words,

b = 2h - 10

We can substitute this expression for b into the equation for the area:

150 = (1/2)(2h - 10)h

Simplifying:

300 = (2h - 10)h

300 = 2h^2 - 10h

2h^2 - 10h - 300 = 0

Dividing both sides by 2:

h^2 - 5h - 150 = 0

Now we can solve for h using the quadratic formula:

h = (-(-5) ± sqrt((-5)^2 - 4(1)(-150))) / 2(1)

h = (5 ± sqrt(625)) / 2

h = (5 ± 25) / 2

We can ignore the negative root (which gives us a negative height), so:

h = 15

Now we can use the expression for b in terms of h to find the base:

b = 2h - 10

b = 2(15) - 10

b = 20

Therefore, the height is 15 meters and the base is 20 meters.

To find the equation of the drone's path, we can first find the coordinates of the center of the circle that the drone is flying around. We can do this by finding the midpoint between the two points the drone passes over:

Midpoint in the x-direction: (220 ft - 180 ft)/2 = 20 ft to the right of the origin.

Midpoint in the y-direction: (230 ft - 180 ft)/2 = 25 ft above the origin.

Therefore, the center of the circle is located at (20, 25) ft.

The radius of the circle can be found by calculating the distance between the center of the circle and either of the two points the drone passes over:

Radius: sqrt((20-(-180))^2 + (25-180)^2) = sqrt(40000 + 15625) = 205 ft (rounded to the nearest whole number)

So the equation for the drone's path is:

(x - 20)^2 + (y - 25)^2 = 205^2

To find how far north of Megan's position the drone is when it passes due north, we can substitute x = 0 into the equation:

(0 - 20)^2 + (y - 25)^2 = 205^2

400 + (y - 25)^2 = 42025

(y - 25)^2 = 41625

y - 25 = +/-sqrt(41625)

y = 25 +/- 204.06

So the drone is either 229.06 ft north or 22.94 ft south of Megan's position when it passes due north. Rounded to three decimal places, the answer is 229.06 ft north.

Answer: Let's assume the two original numbers to be x and y.

If one of them is increased by 50%, then the new value will be 1.5x, and if the other one is decreased by 50%, the new value will be 0.5y.

The product of the two new numbers will be:

1.5x * 0.5y = 0.75xy

So, the new product is 0.75 times the original product. This means the product of the two numbers has decreased by 25%.

To summarize:

If one number is increased by 50% and the other number is decreased by 50%, the product of the two numbers will decrease by 25%.

The new product is 0.75 times the original product.

Answer: a. To shift the graph of f(x) downward 5 units, we subtract 5 from the function: f(x) - 5. To shift it left 3 units, we replace x with x + 3: f(x + 3) - 5. To stretch it vertically by a factor of 4, we multiply the entire function by 4: 4[f(x + 3) - 5]. Finally, to reflect it about the x-axis, we take the negative of the function: -4[f(x + 3) - 5]. Therefore, the equation of the new function g(x) is:

g(x) = -4[1/2^(x+3) - 5]

b. To find the y-intercept, we set x = 0 in the equation of g(x):

g(0) = -4[1/2^(0+3) - 5] = -4[1/8 - 5] = -4[-39/8] = 195/2

Therefore, the y-intercept is (0, 195/2).

c. The domain of g(x) is all real numbers, since there are no restrictions on x.

d. To find the range of g(x), we first observe that the function is decreasing and asymptotic to y = -5 as x approaches infinity. This means that the range of g(x) is all real numbers less than or equal to -5.

To determine the function, f(3), and g(5), we have to substitute the value of x as 3 in the function f(x) and the value of x as 5 in the function g(x).

We have;

f(3) = -5(3) + 2

f(3) = - 13

If the temperature is read every 12 hours, then the eighth temperature reading will be taken at 11.15 pm three days after the first reading.

Temperature is a measure of the degree of hotness or coldness of a substance or object, typically measured using a thermometer in degrees Celsius or Fahrenheit.

If the temperature is read every 12 hours, then the time interval between two consecutive temperature readings is 12 hours.

To find the time of the eighth temperature reading, we need to add 12 hours for each of the previous seven temperature readings:

First reading: 11.15 am

Second reading: 11.15 am + 12 hours = 11.15 pm

Third reading: 11.15 pm + 12 hours = 11.15 am (next day)

Fourth reading: 11.15 am (next day) + 12 hours = 11.15 pm (next day)

Fifth reading: 11.15 pm (next day) + 12 hours = 11.15 am (two days after the first reading)

Sixth reading: 11.15 am (two days after the first reading) + 12 hours = 11.15 pm (two days after the first reading)

Seventh reading: 11.15 pm (two days after the first reading) + 12 hours = 11.15 am (three days after the first reading)

The range, which is the distance between the smallest and greatest linear equation values in the data,  does not take into account the distribution of the data within that range.

In algebra, a linear equation refers to one with its form y=mx+b. B is the gradient, and m is the esta. The preceding clause is commonly referred to as a "linear function with two variables" so even though y and x are variables. Bivariate linear equations are linear equations with two variables. There are several linear equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation seems to have the structure y=mx+b, where m is the slope and b is the y-intercept, it is said to be linear. When a measurement seems to have the formula y=mx+b, both with m identifying its slope and b denoting the y-intercept, it is said to be linear.

Because it has a lower IQR, Fast Chicken can more consistently estimate their wait time (Interquartile Range). In this case, the IQR is the range of the middle 50% of the data, which is the distance between the first and third quartiles.

Super Fast Food, on the other hand, has a higher IQR, indicating that the data is more dispersed. This means that customers report a wider range of wait times, making it more difficult to estimate a consistent wait time. The range, which is the distance between the smallest and greatest values in the data, is not as useful for measuring consistency in this case because it does not take into account the distribution of the data within that range.

Answer:

the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5 is 257/30 = 8 and 39/40.

Step-by-step explanation:

To find the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5, we need to first add the two summands:

4 and 2/3 + 5 and 2/5

To add these mixed numbers, we first need to find a common denominator. The least common multiple of 3 and 5 is 15.

4 and 2/3 can be written as an improper fraction with denominator 3:

4 and 2/3 = 4 x 3/3 + 2/3 = 12/3 + 2/3 = 14/3

5 and 2/5 can be written as an improper fraction with denominator 5:

5 and 2/5 = 5 x 5/5 + 2/5 = 25/5 + 2/5 = 27/5

Now we can add the two fractions with a common denominator of 15:

14/3 + 27/5 = (14 x 5)/(3 x 5) + (27 x 3)/(5 x 3) = 70/15 + 81/15 = 151/15

So, the sum of 4 and 2/3 and 5 and 2/5 is 151/15.

Now we can subtract 1 and 1/2 from this sum:

151/15 - 1 1/2

To subtract mixed numbers, we first need to convert 1 and 1/2 to an improper fraction:

1 and 1/2 = 1 x 2/2 + 1/2 = 2/2 + 1/2 = 3/2

Now we can subtract the fractions with a common denominator of 15:

151/15 - 3/2 = (151 x 2)/(15 x 2) - (3 x 15)/(2 x 15) = 302/30 - 45/30 = 257/30

Therefore, the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5 is 257/30.

The ordered pair solutions for the system of equations are (-2, 5) and (1, 2).

To determine if an ordered pair is a solution to two systems of equations, substitute the values ​​of the variables into each equation. If an ordered pair makes both equations true, it is the solution of the system. 

To find the ordered pair solutions for the system of equations, we need to solve the two equations simultaneously.

f(x) = x² + 1 ...(1)

f(x) = -x + 3 ...(2)

Setting the two equations equal to each other, we get:

x² + 1 = -x + 3

Rearranging this equation, we get:

x² + x - 2 = 0

Factoring this quadratic equation, we get:

(x + 2)(x - 1) = 0

Therefore, the solutions for x are x = -2 and x = 1.

Substituting these values of x into either equation (1) or (2), we get:

For x = -2: f(-2) = (-2)² + 1 = 5, and f(-2) = -(-2) + 3 = 5.

For x = 1: f(1) = 1² + 1 = 2, and f(1) = -1 + 3 = 2.
