A diver jumps from a platform diving board that is 32 feet above water. The height , h of the diver above water , in feet, t seconds after jumping from the platform , can be determined by the equation h=-16t^2+20t+32. Determine the diver's height above water 2 seconds after jumping from the platform.
CAN SOMEONE HELP ME OUT PLEASE!!!!!!!!!!

Answers

Answer 1

Answer:

h=8

Step-by-step explanation:

h = -16t^2 + 20t + 32

h = -16(2)^2 + 20(2) + 32

h = -16(4) + 40 + 32

h = -64 + 72

h = 8

Option B871.5 feet

Step-by-step explanation:

Q1

∠PTQ + ∠QTS = ∠PTS, angle addition postulate

∠PTS is a straight line, therefore equals to 180°

Correct choice is:

B. The angles add to 180°

Q2

1 inch → 83 feet ⇒10.5 inches → 10.5*83 feet = 871.5 feet

HOWDY;)

1.Option B

2.871.5 feet

Q 1

PTQ + QTS =PTS,angle addition postulate

PTS is a straight line,therefore equals to 180°

Step-by-step explanation:

Asnwer:

10,920$

Step-by-step explanation:

So if 3.00$ is for one pack and she wants 7 packs then it would be 21$.

But if we also multiply it by 52 weeks then that would be 1,092$.

Then if she's buying that for 10 years then we multiply 10 x 1,092$ which would equal 10,920$

You can quiet literally write the question as it is.

The difference of a number x and 2 is 7.

This statement can be translated as x-2=7.

It is as simple as that!

What is the value of 9 2/3 minus 4 1/5

Answers

Answer:

5 7/15 = D

Step-by-step explanation:

Find a common denominator multiply the many times you did to the denominator to the numerator then subtract.

15 is your common denominator so I would multiply 5 to 2 to get 9 10/15 then I would multiply 3 to 1 to get 4 3/15

Answer:

5 7/15

Step-by-step explanation:

Let's solve your equation step by step.

We will solve it in just 3 simple steps.

Step 1: Converting into Improper Fraction.

Converting into an Improper Fraction is the only way to subtract fractions.

We will turn 9 2/3 into 29/3

First you need to know:

What is a numerator?

What is a denominator?

What is a whole number?

If you know, you can skip this part.

A denominator is the lower number below the line in a fraction. (ex. 2/3 <-- "3" is the denominator)

A numerator is the higher number above the line in a fraction. (ex. 2/3 <---"2" is the numerator)

A whole number is a number that has no fraction or decimal. (ex. "3" or "2" or "7".)

With that said, let's solve.

In 9 2/3, "9" is the whole number. "2" is the numerator, and "3" is the denominator.

We always multiply the whole number by the denominator, then we add the numerator.

So:

(9 x 3) + 2 = 29

Then, we keep the denominator the same. "3".

We then get:

29/3. Which is what we want.

Let's repeat the same steps with 4 1/5.

(4 x 5) + 1 = 21

Keep the denominator : 21/5

Now we are on Step 2.

We currently have 29/3 - 21/5

But we don't have the denominators the same.

We need to find the LCD (Least Common Denominator of 3 and 5.  

Since these numbers are less than 10, my trick is to just multiply them together. 3 x 5 = 15, simply put.

Now, let's change all the denominators to 15. Now let's change the numerators.

For the fraction that had 3 as the denominator, let's multiply 5 to it. And for the fraction that had 5 as the denominator, let's multiply 3 to it.

We then get :

145/15 - 63/15

We are now on Step 3.

This step is simple. Just subtract 145 - 63 because the denominators are the same.

145 - 63 = 82

We now have 82/15.

This is the answer, but we always need to simplify it.

How many times can 15 fit into 82? 5. But we have 7 left over.

So we now have :

5 7/15

Four friends shared 7 chocolate bars. Each of them was given an equal share of the chocolate bars. How many chocolate bars did each person get?
A: 4/7
B : 6/8
C: 1 1/4
D: 1 3/4

Answers

We are given:

There were 7 chocolate bars, evenly shared between 4 friends

Number of Bars one person will get:

Number of bars one person will get = Number of Bars / Number of Friends

Number of Bars = 7 / 4

but since this number does NOT match any of the given options, we will convert it to a mixed fraction

The number of bars one person will get will be [tex]1\frac{3}{4}[/tex], written as a mixed fraction.

Therefore, the correct answer is option D

Answer:

4 friends =7 chocolate

1 friend =7/4 chocolate =1 3/4 part of chocolate.

What is the value of the expression 3x+9 if x=6

Answers

Answer:

27

Step-by-step explanation:

3(6)=18

18+9=27

Answer:

27

Step-by-step explanation:

You would use PEMDAS to solve this equation, P (parenthesis) E (exponates)  M (multiply) D (divide) A (add) S (subtract). The way you use this is by following the steps in the order that you would spell PEMDAS, so 3x+9 would be 3•6+9. So look at the equation 3•6+9, so what would we use first? do we have parenthesis? No, Do we have exponents? No, Do we have multiplication?  Yes, so multiply 3 and 6 = 18. Now the equation will look like this 18+9 = 27.
