C. 64

Rewrite the logarithm:

8=x^.5

Solve by raising both sides of the equation to the power of the inverse (in this case, the inverse of .5, which is 2):

8^2=x^(.5*2)

64=x

Answer:

$\frac{7}{x+7}$

Step-by-step explanation:

Step 1: Pull a 7 from the top

$\frac{7x + 42}{x^2 + 13x + 42}$

$\frac{7(x + 6)}{x^2 + 13x + 42}$

Step 2: Factor the bottom

$\frac{7(x + 6)}{(x + 7)(x + 6)}$

Step 3: Cancel the top (x+6) and the bottom (x+6)

$\frac{7}{x+7}$

Answer: $\frac{7}{x+7}$

Find the coordinates of the turning point for the equation of the graph below y=x^2+14x+45

USPshnik [31]

Answer:

(- 7, - 4 )

Step-by-step explanation:

Given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the turning point is

x = - $\frac{b}{2a}$

y = x² + 14x + 45 ← is in standard form

with a = 1, b = 14 , then

x = - $\frac{14}{2}$ = - 7

Substitute x = - 7 into the equation and evaluate for y

y = (- 7)² + 14(- 7) + 45 = 49 - 98 + 45 = - 4

coordinates of turning point = (- 7, - 4 )

Suppose you pay back $575 on a $525 loan you had for 75 days. What was your simple annual interest rate? State your result to th

KengaRu [80]

The simple annual interest rate for the $ 525 loan is equal to 46.35 %.

<h3>What is the interest rate behind a pay back?</h3>

In this situation we assume that the loan does not accumulate interests continuously in time. Hence, the interest rate for paying the loan back 75 days later is:

575 = 525 · (1 + r/100)

50 = 525 · r /100

5000 = 525 · r

r = 9.524

The loan has an interest rate of 9.524 % for 75 days. Simple annual interest rate is determine by rule of three:

r' = 9.524 × 365/75

r' = 46.350

The simple annual interest rate for the $ 525 loan is equal to 46.35 %.
