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.

The polynomial function f(x) = 3x5 – 2x2 + 7x models the motion of a roller coaster. The roots of the function represent when th

Answer:

$x=0$

Step-by-step explanation:

We have been given that a polynomial function $f(x)=3x^{5}-2x^{2}+7x$ models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.

In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:

$f(x)=3x^{5}-2x^{2}+7x\\f(x)=x(3x^{4}-2x+7)\\$
