For this case we have the following equation:

h = -16t2 + 32t + 6

Deriving we have:

h '= -32t + 32

Equaling to zero:

-32t + 32 = 0

We clear the time:

t = 32/32

t = 1 s

We are now looking for the maximum height:

h (1) = -16 * (1) ^ 2 + 32 * (1) + 6

h (1) = 22 feet

**Answer:**

**The ball reaches its maximum height in:**

**t = 1 s**

**The ball's maximum height is:**

**h (1) = 22 feet**

**option: 22 ft, 1 s**

h = -16t2 + 32t + 6

Deriving we have:

h '= -32t + 32

Equaling to zero:

-32t + 32 = 0

We clear the time:

t = 32/32

t = 1 s

We are now looking for the maximum height:

h (1) = -16 * (1) ^ 2 + 32 * (1) + 6

h (1) = 22 feet

Question

Amy paid $65.78 for a pair of running shoes during a 40%-off sale. What was the regular price?

Solution 1

This problem can be represented by the following:

sale price = (percentage off) * original price

Plug in the values given by the problem. 60% is represented in this equation as 0.6.

65.78 = 0.6x

Divide both sides by 0.6.

109.63 = x

The original price was**$109.63.**

sale price = (percentage off) * original price

Plug in the values given by the problem. 60% is represented in this equation as 0.6.

65.78 = 0.6x

Divide both sides by 0.6.

109.63 = x

The original price was

Question

a plane takes off at an angle of elevation of 15 degrees and travels in a straight line for 3,000 meters. What is the height of the plane above the ground at this instant?

Solution 1

SOH CAH TOA tells you the sine function of an angle gives the ratio of opposite side to the hypotenuse of the right triangle.

Sin = Opposite/Hypotenuse

In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).

sin(30°) = height/(3000 m)

Multiplying by 3000 m, we get

height = (3000 m)*sin(30°) = 1500 m

The height of the plane at that instant is ...

1500 m

Sin = Opposite/Hypotenuse

In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).

sin(30°) = height/(3000 m)

Multiplying by 3000 m, we get

height = (3000 m)*sin(30°) = 1500 m

The height of the plane at that instant is ...

1500 m

Question

A pizza that was ordered for a party was already cut into 6 slices. If each serving of pizza was 1 3 of a slice, how many servings of pizza were available? A) 18 Eliminate B) 2 C) 1 18 D) 1 2

Solution 1

Hello!

I serving size was 1/3 of a slice

1/3 * 3 = 1

3 serving sizes made one slice

Multiply this by the amount of slices

3 * 6 = 18

There are 18 serving sizes

The answer is 18

Hope this helps!

Question

A group of students recycled 7 2/3 pounds of glass and 9 3/4 pounds of paper. How many pounds of glass and paper did the students recycle alltogether?

Solution 1

The students recycle 17 5/12 **pounds **of **glass **and **paper **all together.

**Fractions **represent the parts of a whole or collection of objects.

A **fraction **has two parts. The number on the top of the line is called the **numerator **and the number on the top of the line is called the **denominator**.

Now it is **given **that,

Pounds of **glass **recycled = 7 2/3

⇒ Pounds of **glass **recycled = 23/3

Pounds of **paper **recycled = 9 3/4

⇒ Pounds of **paper **recycled = 39/4

Thus, **total **pounds of **glass **and **paper **recycled = Pounds of **glass **recycled + Pounds of **paper **recycled

⇒ **total **pounds of **glass **and **paper **recycled = 23/3 + 39/4

⇒ **total **pounds of **glass **and **paper **recycled = 209/12

⇒ **total **pounds of **glass **and **paper **recycled = 17 5/12 pounds

Thus, the students recycle 17 5/12 **pounds **of **glass **and **paper **all together.

Question

If total liabilities are 1,000 and total assets are 8000 owner's e q u i t y must be

Solution 1

Total equity is equal to assets - liabilities.

Therefore,

8000 - 1000 = 7000

The owner's equity is**$7,000.**

Therefore,

8000 - 1000 = 7000

The owner's equity is

Question

n May, Bradley bought 48 Styrofoam balls and decorated them as toy figurines. In June, he sold 19 figurines. In May, Lupe bought 44 Styrofoam balls to decorate, and in June, she sold 21 figurines. Which matrix represents all of their May purchases and their June sales?

Solution 1

**Answer: The matrix would be **

**Step-by-step explanation:**

Since we have given that

Number of Styrofoam balls bought by Bradley in May = 48

Number of figurines sold by Bradley in June = 19

Number of Styrofoam balls bought by Lupe in May = 44

Number of figurines sold by Lupe in June = 21

So, it will be written as

** Purchases Sales **

**May ** 48 19

**June ** 44 21

**So, the matrix would be **

Solution 2

48 19

44 21. this is what it should look like

44 21. this is what it should look like

Question

Yanis fires pottery in a kiln. He decides to measure the rate of change of temperature of the pottery over time. What would be an appropriate unit for Yanis's purpose?

Solution 1

**Answer with explanation:**

Pottery is on a Kiln.

Unit of temperature can be Kelvin(°K) or Degree Celsius(°C) or Fahrenheit(°F).

Unit of time is second, minute and hour.

**Rate of change of temperature of the pottery over time can be written as**

Internationally , **Kelvin is used as S.I unit of Temperature.**

**So,Yanin can use **

** **

as Rate of change of temperature of the pottery over time.

Solution 2

Degrees celcius/ hour
