5. A rock is thrown directly upward with an initial velocity of 79 feet per second from a cliff 50 feet above a beach. The height of the rock above the beach (h) after t seconds is given by the equation h = -16t² + 79t + 50. The graph below shows the rock's height as a function of time.

Answers

Answer 1

5. The quadratic function for the height of the rock, h = -16·t² + 79·t + 50, indicates;

a. The height of the rock will be 125 feet above the beach at 1.28 seconds and 3.66 seconds after it is thrown

b. The maximum height reached is about 147.5 feet

The time it takes the rock to reach the maximum height is about 2.47 seconds

What is a quadratic function?

A quadratic function is a function of the form; f(x) = a·x² + b·x + c, where, a, b, and c are numbers, and a ≠ 0.

The initial velocity of the rock = 79 ft/s

Height of the cliff above the beach from which the rock is thrown = 50 feet

The function for the height of the rock above the beach is; h = -16·t² + 79·t + 50

Please find attached the graph of the height of the rock as a function of time, created with MS Excel.

Required; When the height of the rock will be 125 feet above the beach

When the height of the rock is 125 feet, we get;

h = 125 = -16·t² + 79·t + 50

-16·t² + 79·t + 50 - 125 = 0

-16·t² + 79·t - 75 = 0

The value of t obtained using an online tool are;

t = (79 + √(1441))/32 ≈ 3.66 and t = (79 - √(1441))/32 ≈ 1.28

The times at which the height of the rock will be 125 feet above the beach are; 1.28 seconds and 3.66 seconds after the rock is thrown

b. The maximum height of the rock can be obtained from the formula for finding the maximum height of a quadratic equation of the form; f(x) = a·x² + b·x + c, which is;

At the maximum point, x = -b/(2·a)

The function for the height; h = -16·t² + 79·t + 50, indicates that we get;

a = -16, b = 79, and c = 50

Therefore;

The time it takes the rock to reach the maximum height, t(max), is therefore;

t(max) = -79/(2 × (-16)) ≈ 2.47

It takes about 2.47 seconds for the rock to reach the maximum height

The maximum height, h(max) = -16 × 2.46875² + 79×2.46875 + 50 ≈ 147.5

The maximum height reached by the rock is about 147.5 feet

Possible part of the question, obtained from a similar online question, includes;

a. The time it takes the rock to reach a height of 125 feet above the beach
b. The maximum height reached by the rock and the duration it takes the rock to reach the maximum height.

Please find attached the possible graph in the question, created with MS Excel, using the function for the height of the rock.

The amount that would be in the account after 20 years would be $33,277.48.

The doubling time of the emissions would be  23.45 years

The total emissions will be higher in 2030 than 2010 by 100.96%

How to find the amount after years of investment ?

To find the amount in the account after 20 years, we can use the formula:

A(t) = P(1 + r)^t

Take the 12th root of both sides:

(1 + r) = 2^(1/12)

Now find r:

r = 2^(1/12) - 1 ≈ 0.05946

Now we can find the amount in the account after 20 years with the investment of $10,000:

A(20) = 10000(1 + 0.05946)^20

A(20) = $33,277.48

How to find the doubling time ?

To find the doubling time for emissions, we can use the formula:

Doubling time = ln(2) / ln(1 + r)

Doubling time = ln(2) / ln(1 + 0.03)

Doubling time = 23.45 years

To find how much higher total emissions will be in 2030 than in 2010, we can use the exponential growth formula:

E(t) = E₀(1 + r)^t

We want to find the ratio of emissions in 2030 to emissions in 2010:

E(20) / E(0) = (1 + 0.03)^20

E(20) / E(0) ≈ 2.0096

Higher emissions = E(20) / E(0) - 1

Higher emissions ≈ 1.0096

So, total emissions will be approximately 100.96% higher in 2030 than in 2010.

Case 9: BC = 4.585, AC = 8.999

Case 10: AB = 10.461, BC = 7.774

How to determine the missing sides in right triangles

In this problem we have four cases of right triangles, each of which has a known side and a known angle and we must determine all the missing lengths by trigonometric functions:

sin θ = y / r

cos θ = x / r

tan θ = y / x

Where:

x - Leg adjacent to an angle.y - Leg opposite to an angle.r - Hypotenuse.θ - Angle, in degrees.

Now we proceed to determine the values of the missing lengths:

Case 7

AC = 14 · sin 44°

AC = 9.725

BC = 14 · cos 44°

BC = 10.071

Case 8

AB = 10 / cos 62°

AB = 21.301

BC = 10 · tan 62°

BC = 18.807

Case 9

BC = 10.1 · sin 27°

BC = 4.585

AC = 10.1 · cos 27°

AC = 8.999

The width of a rectangle is 2 units less than the length. The area of the rectangle is 24 square units. What is the length, in units, of the rectangle?

Answers

The width of a rectangle is 2 units less than the length. The area of the rectangle is 24 square units. The length of the rectangle is 6 units.

Let's denote the length of the rectangle as L and the width as W. According to the given information, the width is 2 units less than the length, so we can express this relationship as:

W = L - 2

The formula for the area of a rectangle is A = L * W, and in this case, the area is given as 24 square units. Substituting the values, we have:

24 = L * (L - 2)

Expanding the equation, we get:

24 = L^2 - 2L

Rearranging the equation and setting it equal to zero, we have:

L^2 - 2L - 24 = 0

We can now factor the quadratic equation:

(L - 6)(L + 4) = 0

Setting each factor equal to zero, we have two possible solutions:

L - 6 = 0 or L + 4 = 0

Solving each equation, we find:

L = 6 or L = -4

Since the length cannot be negative, the length of the rectangle is 6 units.

The length of the rectangle is 6 units.

A bag of 100 marbles contains an equal amount of marbles that are blue, green, red, yellow, and orange. If one marble is pulled at random from the bag, the probability that it is a green marble is

Answers

The probability of drawing a green marble from the bag can be calculated as the number of green marbles over the total number of marbles in the bag. Since there are an equal amount of each color marble in the bag, there are 100/5 = 20 marbles of each color. Therefore, there are 20 green marbles in the bag.

The probability of pulling a green marble is the number of green marbles (20) divided by the total number of marbles (100):

P(green marble) = 20/100 = 0.2 = 20%

Therefore, the probability of pulling a green marble from the bag is 20%.

Answer:

38 in²

Step-by-step explanation:

We can solve for the area of this trapezoid by using the area formula:

[tex]A = \dfrac{b_1 + b_2}{2} \cdot h[/tex]

First, we need to identify the trapezoid's bases ([tex]b_1[/tex] and [tex]b_2[/tex]). We know that the bases of a trapezoid are parallel. Using this information, we can identify 8 in and 11 in as the bases.

Next, we need to identify the height ([tex]h[/tex]). We know that the height of a trapezoid is the length from [tex]b_1[/tex] and [tex]b_2[/tex] that is perpendicular (at a right angle) to both of the bases. We can identify this as 4 in because we can see that it adjoins at a right angle to both of them.

Finally, we can plug these values into the area formula and solve for A.

[tex]A = \dfrac{8 + 11}{2} \cdot 4[/tex]

[tex]A = \dfrac{19}{2} \cdot 4[/tex]

Answers

The value of t is equal to 4.

The equation of PR is y = -x + 6.

The area of the rhombus is equal to 32 square units.

How to determine the value of t and the coordinates of R?

Since BPCR is a rhombus and all the side lengths of a rhombus are always equal in length, we would use the distance formula to determine the length of BP as follows:

Distance BP = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance BP = √[(0 - 2)² + (6 - 0)²]

Distance BP = √[4 + 36]

Distance BP = √40 units.

Also, side length BP is equal to side length PC:

√40 = √[(t - 6)² + (6 - 0)²]

√40 = √[(t - 6)² + 36]

40 = (t - 6)² + 36

(t - 6)² = 4

t - 6 = ±2

t = 6 ± 2

t = 8 or t = 4.

Therefore, C should be located at (6, 4).

Since Q is the midpoint PR and BC, we know that B is shifted 2 units right and 6 units down from P. Therefore, point R is represented by R(8, -2).

In order to determine the equation of PR, we would use the point-slope form:

[tex]y - y_1 = \frac{(y_2- y_1)}{(x_2 - x_1)}(x - x_1)\\\\y - 6 = \frac{(-2-6)}{(8 - 0)}(x - 0)[/tex]

y - 6 = -1(x)

y = -x + 6

In Mathematics, the area of a rhombus is calculated by using this formula:

Area = 1/2(d₁ × d₂)

Where:

d₁ and d₂ represent the diagonals of a rhombus.

PR = 2BC

8√2 = 2BC

BC = (8√2)/2

BC = 4√2

Area of rhombus = 1/2(PR × BC)

Area of rhombus = 1/2(8√2 × 4√2)

Area of rhombus = 1/2(64)

Area of rhombus = 32 square units.

are the roots
of the quadratic equation x^2- 3x + 2 = 0

Answers

The quadratic equation is; x^2 -6x + 8 = 0

What is a quadratic equation?

A quadratic equation is a mathematical equation of the form ax^2 + bx + c = 0, where x is the unknown variable, and a, b, and c are constants (numbers). The exponent of x in the equation is 2, which means it is a second-degree polynomial equation.

We know that the solution of  x^2- 3x + 2 = 0 is x = 2 and x = 1 hence;

α = 2, β = 1

We have that;

αβ^2 = 2

α^2β = (2)^2(1) = 4

The equation would now be;

x^2 - (2 + 4)x - (2 * 4) = 0

Workout AG in the cuboid below. (3d trig)

Answers

The length of the diagonal AG = 7.56 cm.

Finding diagonal of cuboid:

A cuboid is a three-dimensional shape that is bounded by six rectangular faces. It is also known as a rectangular prism. A cuboid has six faces, twelve edges, and eight vertices.  

To find the Length of the side AG, find the length of AC by using the Pythagorean formula. Now using the trigonometric ratios formulas find the length of AG.

Here we have a cuboid

Where

AD = 23 cm

DC = 18 cm

∠GAC = 75°  

From the right angle triangle, ADC

=> AC² = AD² + DC²    [ Using the Pythagorean formula ]

=> AC² = (23)² + (18)²

=> AC² = 529 + 324

=> AC = √853 = 29.20    

From the right angle triangle, AGC

=> Cos B = AC/AG

=> Cos 75° = 29.20/AG

=> AG = Cos 75° (29.20)

=> AG = (0.26)(29.20)

=> AG = 7.56

Therefore

The length of the diagonal AG = 7.56 cm.

Using the substitution method to solve the following system .if the equations of the systems are dependent ,or if the system is inconsistent,so indicate.


y = 3x
x + y = 8

Answers

Answer:

[tex]x = 2 , y = 6[/tex]

Step-by-step explanation:

The substitution method suggests that you will "substitute" a portion of one given equation to another in the system of equation:

In this case, substitute 3x for y in the 2nd equation:

[tex]y = 3x\\x + y = 8\\\\x + (3x) = 8[/tex]

Simplify. Combine like terms. Like terms are terms with the same amount of the same variable.

[tex]x + 3x = 8\\4x = 8[/tex]

Next, isolate the variable, x. Divide 4 from both sides of the equation:

[tex]4x = 8\\\frac{4x}{4} = \frac{8}{4} \\x = \frac{8}{4}\\ x = 2[/tex]

Next, plug in 2 for x in one of the equations, and simplify to solve for y:

[tex]y = 3x\\y = 3(2)\\y = 6[/tex]

Check: Plug in 2 for x and 6 for y in the second equation:

[tex]x + y = 8\\(2) + (6) = 8\\8 = 8[/tex](True)

[tex]x = 2 , y = 6[/tex] is your answer.

The number of hamburger sold on Tuesday is 136.

How to find the number of hamburgers sold on Tuesday?

On Tuesday, a local hamburger shop sold a combined total of 408

hamburgers and cheeseburgers. The number of cheeseburgers sold was

two times the number of hamburgers sold.

Therefore, the number of hamburger sold on Tuesday can be calculated as follows:

Let

x = number of hamburger

y  =number of cheeseburger

Therefore,

x + y = 408

2x = y

x + 2x = 408

3x = 408

divide both sides by 3

x = 408 / 3

x = 136

Therefore,
