a skydiver jumps out from the plane at 10,000 feet above the ground. the skydiver decends at a rate of 175 feet per seconds. how high in the air is the skydiver when he opens his parachute after 25 seconds?

Answers

Answer:

5625 feet

I hope it's helps you

Answer:

5625 feets

Step-by-step explanation:

Rate(feet/seconds) = height(feets)/time(seconds)

175 = x/25

x = 4375

After the skydiver opens his parachute the height reduces

Initial height – reduced height

10000 – 4375

= 5625 feets

Answer:

Function 1: None of the Above

Function 2: Quadratic

Function 3: Linear

Step-by-step explanation:

Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.

Function 2: It has a vertex-(6,32)

Function 3: The y-axis goes up at a constant rate of 6.

While walking to the gym, Marie decides to play a game using a her lucky fair
six-sided die (which she carries with her all the time). Tossing an even number would
indicate walking forward that many steps and, likewise, tossing an odd number would
mean walking backwards that many steps (i.e. if she tosses a 3, she walks backward 3
steps). If the probability that after 2 rolls of the die, she is further away from the gym
that she was at the beginning of the game, can be represented as m/n
for m and n being relatively prime positive integers, find m^2 + n^2 ?

She will have to earn $3,100

Step-by-step explanation:

6,600-3,500=3,100

3,100

You add up what she is getting and than subtract how much she needs with what she has so far. And that’s the answer. So 2000+ 1500= 3500 than 6,600-3500

Sue saved $360. She spent 75% of her savings. How much does she have left

Answers

Answer:

Step-by-step explanation:

Expense = 75%

Percentage of amount left = (100 -75)% = 25%

25% of 360 = 0.25* 360 = 90

Remaining amount left with Sue = $ 90

She would only have 25% remaining so 25% times 360 is $90

1)88 2)44.5

Step-by-step explanation:

i'm not sure about 3 and 4

Answer:

1.) 88cm²

2.) 44.5cm²

3.) 141.37cm²

4.) 44cm²

Step-by-step explanation:

Alrighty, we're just going to do an abridged version, but if you need me to explain it more, I can:

1.) 6 x 8 ÷ 2 = 24

8 x 8 = 64

64 + 24 = 88

1.) 88cm²

2.) 2 + 2 + 3 = 7

7 x 5 ÷ 2 = 17.5

9 x 3 = 27

27 + 17.5 = 44.5

2.) 44.5cm²

3.) 3.14 x 3² = 28.27

3.14 x 6² = 113.1

28.27 + 113.1 = 141.37

3.) 141.37cm²

4.) 3.14 x 4² ÷ 2 = 25.135

4 x 2 = 8

8 x 9 ÷ 2 = 36

8 + 36 = 44

4.) 44cm²

Answers

Answer:

B

Step-by-step explanation:

I am not sure what your teacher wants but I guess you can say the following:

at n = 1, the cost is 4 dollars.

at n = 2, the cost is 8 dollars.

This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.

For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.
