Answer:

1. A

2. E

3. B

4. C

5. D

Step-by-step explanation:

1. Hitting a golf on the moon will give higher max height and farther distance due to low gravity. Equation A show 500x giving sum of root (SOR) -500/16 the highest sum among other showing that the distance between roots are larger

2. Hitting golf on top of tall building will have initial height higher compared from the rest. By subs x=0, the highest initial height is equation E with h = 300

3.jupiter has stronger gravity compared to earth and moon, hence max height will be lower than Moon and earth. The lowest max height is shown on equation B

4. A bionic man can hit stronger hence must have higher max height compared to the tall man. Either C or D. Choose C since the maximum height is higher than D

5. A 10 foot person has higher height compared to normal. At x = 0, h(x) for D is 8 which is around the arm height of the tall person. And the maximum hitting height of equation D is relatively lower than C. So option D is more logical for this tall person.

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each,

Sav [38]

Answer:

6 laptops

Step-by-step explanation:

First, find the amount spent on the textbooks:

30(116)

= 3480

Subtract this from the total amount they have to spend:

6500 - 3480

= 3020

Divide this amount by 439 to find how many laptops they can buy:

3020/439

= 6.8

Round down to 6 since you can only have full laptops:

= 6

So, they can buy 6 laptops

A) exponential is the right answer.

Step-by-step explanation:

The formula used for increase after same number of time is:

$A_t = A_0(1+r)^t\\Here\\A_0\ is\ the\ initial amount\\r\ is\ the\ rate\\and\\t\ is\ time$

We are given

A_0 = 35000

r = 3%

$A_t = 35000(1+0.03)^t\\A_t = 35000(1.03)^t$

The function is an exponential function is the value of t can be put equal to 1,2,3,4..... which will increase the final output exponentially

Hence,

A) exponential is the right answer.

1. Consider a lottery with three possible outcomes:-$125 will be received with probability 0.2-$100 will be received with probab

Norma-Jean [14]

Answer:

The expected value of the lottery is $80

Step-by-step explanation:

To get the expected value, we have to multiply each outcome by its probability

Then we proceed to add up all of these to get the expected value of the lottery

we have this as ;;

125(0.2) + 100(0.3) + 50(0.5)

= 25 + 30 + 25 = $80
