Answer:

The bottom question is wrong. You have to multiply 8 to get the amount earned. But the rest is correct.

Step-by-step explanation:

6.25 x 8 = 50

12.5 x 8 = 100

18.75 x 8 = 150

25 x 8 = 200

31.25 x 8 = 250

With what initial velocity must an object be thrown upwards so that it will reach a maximum height of 800 feet? Assume the that

Flauer [41]

Answer:

Option b is right.

Step-by-step explanation:

When an object is thrown upwards, the acceleration acting is acceleration due to gravity in a negative manner.

a = -32 ft/sec square

Initial velocity let it be u

Final velocity when it reaches maximum height is 0

Use the formula connecting, u, v, a and s

$v^2=u^2+2as\\0 = u^2-2(32)(800)\\u = \sqrt{64(800)} \\u = 160*0.707\\= 226.27$ ft/sec

Hence we find that initial velocity is 226 ft/sec

Option b is right.

Are the expressions (4x)^2 and 4x^2 equal in value? How would you explain your answer?

Nastasia [14]

additon or subtraction

(4x)^2=4x times 4x
4x^2=4 times x times x=4(x^2)

(4x)^2=16x^2
4x^2=4(x^2)
values are not equal
(just for fun: 4x^2=(2x)^2)
