Given h(x) = 4x + 3, find h(5)

The tennis ball will hit the ground [tex]5[/tex] seconds after being dropped from an initial height of  [tex]400[/tex]feet.

To determine when the tennis ball hits the ground, we need to find the value of t when h becomes 0, since at that time the height of the ball is zero, which means it has hit the ground.

So, we can set  [tex]h = 0[/tex] and solve for t:

[tex]0 = -16t^2 + 400[/tex]

Adding 16t^2 to both sides:

[tex]16t^2 = 400[/tex]

Dividing both sides by 16:

[tex]t^2 = 25[/tex]

Taking the square root of both sides:

[tex]t = \pm5[/tex]

Since we cannot have a negative time, we can disregard the negative solution.

Therefore, the tennis ball will hit the ground  [tex]5[/tex] seconds after being dropped from an initial height of  [tex]400[/tex] feet.

Answer:

The height of the statue is 152ft.

Step-by-step explanation:

305 = 153 + h

152 = h

The maximum volume of the silo is V = SA/8(4-π), where SA is the surface area of the cylinder formed by the 2000 square feet of material.

We are given that 2000 square feet of material will be used to form a cylinder-shaped silo. We need to find the maximum volume of the silo.

Let's use the formula for the cylindrical surface area:

SA = πr^2 + 2πrh

We can solve for h in terms of r as follows:

SA = πr^2 + 2πrh

2πrh = SA - πr^2

h = (SA - πr^2) / (2πr)

Now, let's substitute this expression for h into the formula for the volume of a cylinder:

V = πr^2h

V = πr^2[(SA - πr^2) / (2πr)]

V = (SA - πr^2) / 2

We want to find the maximum volume, so we need to find the value of r that maximizes V. To do this, we can take the derivative of V with respect to r and set it equal to zero:

dV/dr = -πr/2 + SA/4π = 0

Solving for r, we get:

r = √(SA/(2π))

Substituting this value of r back into the expression for V, we get:

V = (SA - π(SA/(2π))^2) / 2

V = (SA - SA^2/(4π)) / 2

V = SA/8(4-π)

Therefore, the maximum volume of the silo is V = SA/8(4-π), where SA is the surface area of the cylinder formed by the 2000 square feet of material.

Answer: Let's first determine the number of hours SCVCS will be renting the Koger Center from 10:00 am to 3:00 pm. There are 5 hours between 10:00 am and 3:00 pm, so the rental time is:

Rental time = 5 hours

Using this information, we can write an equation to model the total cost of renting the Koger Center, y, as a function of the rental time, x, in hours:

y = 425x + 500

Here, the slope of the line represents the rental cost per hour, and the y-intercept represents the setup/cleanup fee.

Substituting x = 5 into the equation, we get:

y = 425(5) + 500

y = 2125 + 500

y = $2,625

Therefore, it will cost $2,625 to rent the Koger Center from 10:00 am to 3:00 pm.

So, the completed expression is:

y = 425x + 500

Substitute x = 5 into the equation.

It will cost $2625 to rent the Koger Center.

The model P = at + b, which can interpret the period of its graph.

What is an arithmetic progression?

An arithmetic progression is a sequence of numbers where each term is obtained by adding a fixed number to the previous term. In other words, if we have a sequence a1, a2, a3, that is arithmetic, then a2 - a1 = a3 - a2 = d, where d is a common difference.

To write a model that gives P as a function of t, we can use the general form of an arithmetic sequence:

P= at + b

where a is the common difference and b is the initial value of the sequence. To find a and b, we can use the information given in the table. For example, we can use the first two data points to get:

P1 = a(1)+b

P2 = a(2)+b

Subtracting the first equation from the second gives:

P2 - P1 = a(2-1)

​or

a = P2 - P1

​

Once we have a, we can use either of the equations above to solve for b. For example, using the first equation, we get:

b = P1 − a(1)

Now that we have the model P = at + b, we can interpret the period of its graph.

The period of an arithmetic function is the smallest positive value of k such that f(x) = f(x + k) for all x. In this case, the function is linear, so it has no periodic behavior.

hence, the model P = at + b, which can interpret the period of its graph.

Step-by-step explanation:

The area of the shaded region is 170.88 sq. cm.

A circle with a radius of 6 cm is inside a circle with a radius of 9.5 cm.

The area of a circle is given by the formula:

A = πr²Where,A = Areaπ = 3.14r = radius

For the shaded area, we need to subtract the area of the smaller circle from the larger circle.

the radius of the larger circle is 9.5 cm and the radius of the smaller circle is 6 cm.

So, the area of the shaded area can be given as:

Area of the shaded region = Area of larger circle - Area of smaller circle

Area of larger circle = πr²= π(9.5)²= π(90.25) sq. cm.= 283.92 sq. cm.

Area of smaller circle = πr²= π(6)²= π(36) sq. cm.= 113.04 sq. cm.

So, the area of the shaded region is:

Area of the shaded region = 283.92 - 113.04= 170.88 sq. cm.

Therefore, the area of the shaded region is 170.88 sq. cm.

Sascha receives 3.65% more percentage yield from the corporate bond than from dividends.

What is percentage yield?

To find out how much more percentage yield Sascha receives from the corporate bond than from dividends, we need to calculate the yield for each investment and compare them.

For the corporate bond:

Annual interest = 8.07% of $8,706 = $703.24

Yield = Annual interest / Bond value = $703.24 / $8,706 = 0.0809 or 8.09%

For the stock:

Dividend yield = Annual dividend / Stock value = $2 / $45 = 0.0444 or 4.44%

To find out the difference in percentage yield, we subtract the dividend yield from the bond yield:

8.09% - 4.44% = 3.65%

Answer: To solve the equation Three-fifths (30 x - 15) = 72, we can start by simplifying the left side of the equation by distributing the coefficient 3/5 to the terms inside the parenthesis:

Three-fifths (30 x - 15) = 72

18x - 9 = 72 (dividing both sides by 3/5)

Multiplying both sides of the equation by 5/3, we get:

10x - 5 = 24

10x = 29

x = 2.9

So the value of x for the original equation is x = 2.9.

Now we can test each option to see which equations have the same value of x:

18x - 15 = 72

18(2.9) - 15 = 40.2

This equation does not have the same value of x as the original equation.

50x - 25 = 72

50(2.9) - 25 = 125

This equation does not have the same value of x as the original equation.

18x - 9 = 72

18(2.9) - 9 = 40.2

This equation does not have the same value of x as the original equation.

3(6x - 3) = 72

3(6(2.9) - 3) = 72

This equation has the same value of x as the original equation.

x = 4.5

This equation does not have the same value of x as the original equation.

Therefore, the equations that have the same value of x as the original equation are:

We need to first convert the length and width to the same units. We can convert them to twelfths of a meter, since both 6 and 4 are factors of 12.

Length = 3 and 2/6 meters = 3 x 12/6 + 2/6 = 18/6 + 2/6 = 20/6 = 10/3 twelfths of a meter

Width = 2 and 3/4 meters = 2 x 12/4 + 3/4 = 24/4 + 3/4 = 27/4 twelfths of a meter

Now we can find the area:

Area = length x width = (10/3) x (27/4) = 90/12 = 15/2 = 7.5 square meters

Therefore, the answer is option C) six and five-tenths m² (rounded to one decimal place).
