For the first, the initial value is found by finding y when x=0
When x=0
y=4 so the initial value is 4, making your answer
B. 4


For the second one take any two points and do y2-y1/x2-x1
We'll use points 0,0 and 1,3
3-0= 3
1-0=1
So the equation is 3/1x and there's no y intercept
So your answer is
D. y=3x



The speed of the motor boat is 62mph
So your answer is
A.62 miles per hour



The fixed amount is the same as the y intercept, so when x is 0
Y is 8
So your answer is B.$8

Suppose you hit a fly ball with an initial upward velocity of 20 feet per second. Which of the following equations would be a re
baherus [9]
A=g≈-32

v=⌠a dt  since a≈-32

v=-32t+C, where C is the initial velocity, which we are told is 20 ft/s

v=-32t+20

h=⌠v dt

h=-32t^2/2+20t+C, where C is the initial height, so what is a reasonable initial height?  How about 3 ft since we are swinging a bat around maybe our waist level... maybe :P

h=-16t^2+20t+3

Your choices may have made a different assumption about the initial height of course but you did not show your choices, but certainly it will be:

h(t)=-16t^2+20t+hi, where hi is the initial height in feet.

This of course ignores air resistance and flight dynamics of a spinning ball with seams, which will make a significant difference in real life :)

Heba ate 1/12 of a box of cereal. Now the box is 3/4 full.
Alex Ar [27]
3/4 = 3/4*1

3/4 = 3/4 * 3/3 = 9/12

Box is 9/12 full after heba ate 1/12 of a box of cereal

Initial fraction will be 9/12+1/12

=10/12= 5/6

You invest AED 5000 in a saving account that earns 4% interest each year. If you do not use the account for a year, how much mon
Viktor [21]

Answer:

5200 AED or 1404 USD

Step-by-step explanation:

You have 5000 in your account. If your money grows 4% each year, it's basically like multiplying by 1.04.

5000 * 1.04 = 5200

If the question is asking in USD, the conversion rate from AED to USD is

AED * 0.27 = USD

We can substitute

5200 AED* 0.27 = 1404 USD.
