$({4}^{11} \times {4}^{1} ) ^{3}$
put 11 for p

${}^{11 + } {}^{1}$
add exponents. base stays the same
$({4}^{12} ) ^{3}$
multiply exponents. base stays same
$12 \times 3$
answer:
${4}^{36}$
His answer is inncorrect becase he added the exponents 12 and 3 instead of multiplying. You multiply exponents when one is raised to another.
for example:
$({2}^{2} ) ^{3 } \\ 2 \times 3 \\ {2}^{6}$
still check internet to make sure if im right.

A baseball is thrown with a vertical velocity of 50 ft/s from an initial height of 6 ft. The height h in feet of the baseball ca

marin [14]

To find the time to reach the maximum height you can subtract the constant 6 and write the function as:

h'(t) = -16t^2 + 50t

Then factor it: h'(t) = -2t(8t-25)
Then find the two roots:
t =0 and
8t - 25 = 0 ⇒ t = 25/8 = 3.125

The vertex is in the half between 0 and 3.125, i.e. [0+3.125]/2 = 1.5625

Then the time searched is approximately 1.56 seconds.

Jeremiah paid $29.52 for a pair of boots thatwere on sale. The original price of the boots was$36.00. Enter the percentage disco

Colt1911 [192]

Remark

The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?

Solution

36 * (x/100) = 29.52 Multiply both sides by 100

36 * x = 29.52 * 100 The 100 on the left disappears.

36 * x = 2952 The decimal disappears. Divide by 36

x = 2952/36

x = 82%

That is not your answer. That just tells you what % of 36 is that would give 29.52

Answer

The % discount is 100 - 82 = 18%. That is the % discount.
