he baseball team pitcher was asked to participate in a demonstration for his math class. He took a baseball to the edge of the roof of the school building and threw it up into the air at a slight angle so that the ball eventually fell all the way to the ground. The class determined that the motion of the ball from the time it was thrown could be modeled closely by the function
h(t)=16t^2+64t+80
Where h(t) represents the height of the ball in feet after t seconds.

1. By looking at the equation, how can you determine whether the function has a maximum or a minimum value? (1 point)
2. Find the maximum or minimum value of the function algebraically. After how many seconds did the ball reach this value? Show how you found your answers. (2 points)
3. Evaluate h(0). Explain this value in the context of the problem. (1 point)
4. How long is the ball in the air? Justify your answer. (2 points)
5. State the domain of the function in interval notation, and explain the restrictions on the domain based on the context of the problem. (2 points)

Solve the equation. 36^6x-1 = 6^5x

Answers

x=2/7 or x=0.285714 repeating

The solution of the equation 36⁶x - 1 = 6⁵x is  x = 1/2176774560.

What is an equation?

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

We have the equation:

36⁶x - 1 = 6⁵x

Simplifying,

(6²)⁶x - 1 = 6⁵x

6¹²x - 6⁵x = 1

2176782336x - 7776x = 1

x = 1/2176774560

The above equation is the required solution.

Therefore, the required value is x = 1/2176774560.

For a rectangle with length of
3x + 4 and perimeter of 10x + 18,
what is the width of the
rectangle? Reminder, there are
two lengths and two widths in a
rectangle

Answers

Answer:

2x+5

Step-by-step explanation:

Formula for the perimeter of a reactangle= 2(l+b)

So,

2(l+b) = 10x+18

2(3x+4 + b) = 10x+18

Rearrange and solve

3x+4+b = 5x+9

b = 5x+9 - 3x - 4

b = 2x+5

Thus the measurement of the width = 2x+5

The total surface area of the block is 32.6 square inches.

Given that, Jake has a block shaped like the prism shown in a set of toys.

What the surface area of a prism?

To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.

The total surface area of a prism = (2 × Base Area) + (Base perimeter × L).

Here, area = 2 ×1/2×2×2.3 +(2+2.5+2.5)×4

= 4.6+28

= 32.6 square inches

Therefore, the total surface area of the block is 32.6 square inches.

A trampoline was originally priced at $100 but went on sale for 60% off. If Emmett bought the trampoline and paid 5% sales tax, how much did he pay in total? $

Answers

Answer: $42

Step-by-step explanation:

Since the trampoline was originally priced at $100 but went on sale for 60%, the price paid will be:

= $100 - (60% × $100)

= $100 - (0.6 × $100)

= $100 - $60

= $40

Emmett bought the trampoline and then paid 5% sales tax, the total amount paid will be:

= $40 + (5% × $40)

= $40 + (0.05 × $40)

= $40 + $2.

= $42

She paid $42 in total.

find the area of the shape below

Answers

Answer:

235 cm²

Step-by-step explanation:

Find area of the large rectangle on the bottom. To do that, find its length and width, then multiply them together.

Length of big rectangle=20 cm

Width of big rectangle=9 cm

20x9=180 cm²

Next, find the area of the small rectangle on the top. To do that, find its length and width, then multiply them together.

Length of small rectangle=11 cm

Width of small rectangle=5 cm

I found the width by subtracting 9 from 14, since the 9 cm is part of the large rectangle.

11x5=55 cm²

Add the areas of the two rectangles.

Find the values of x and y

Answers

Answer:

y = 70 degrees

x = 11

Step-by-step explanation:

The side opposite x + 2 is equivalent so they will both be equal to 13.

To get the meaning of x, simply subtract 2 from 13 giving you x = 11.

Y is across from corner C, which is 70 degrees. These angles are equivalent to each other, meaning that angle y is also 70 degrees.

Hope this helps you :)

Answer:

x = 11

y = 70°

Step-by-step explanation:

x + 2 = 13

The lines on each side are corresponding.

11 + 2 = 13

Y is corresponding with the 70° corner.

That means the corresponding corner (y) is also 70°.
