Solve 4^(x+2) = 12 for x using the change of base formula log base b of y equals log y over log b.

nalin [4]

Answer:

x=ln(12)/ln(4)-2

Step-by-step explanation:

4^(x+2)=12

x+2=ln(12)/ln(4)

x=ln(12)/ln(4)-2

What is the multiplicative inverse of the sum of 1/3 + 1/5 ? Express in simplest form

Dima020 [189]

$\frac{8}{15}$

My Work/Reasoning:
First we find the sum of 1/3 and 1/5. $\frac{1}{3} + \frac{1}{5} = \frac{5}{15} + \frac{3}{15} = \frac{8}{15}$
Then, we find the multiplicative inverse, I guess it's also known as the reciprocal. $\frac{8}{15}$ turns into $\frac{15}{8}$
Finally, we simplify. $\frac{15}{8}=1 \frac{7}{8}$

19. The temperatures at sunrise and sunset<br> are shown in the table

Likurg_2 [28]

The temperature change on the second day is greater than the temperature change on the first day.

<h3>What is temperature change?</h3>

The term temperature change refers to the difference in the temperature between the sunrise and the sunset. The temperature at sunrise and sunset are shown in the table attached to this answer.

The change in temperature on the first day is;

13.49 - (-11.31) = 24.80

The change in temperature on the second day is;

25.25 - (-7.69) = 32.94

Thus, the temperature change on the second day is greater than the temperature change on the first day.

What is a difference of squares that has a factor of x+8?

uysha [10]

Answer:

x^2 - 64

Step-by-step explanation:

A difference of squares is a special product in the form (a^2 - b^2)..their factored form is (a - b)(a + b)..

Thus here a = x and b = 8, thus if x + 8 is a factor, then x - 8 is also a factor..

(x + 8)(x - 8) <-- expand this out using difference of squares rules..

= (x)^2 - (8)^2

= x^2 - 64 <-- answer...

You could also expand that using FOIL (FOIL - first, outer, inner, last)..

(x + 8)(x - 8)

= (x)(x) + (x)(-8) + (8)(x) + (8)(-8)

= x^2 - 8x + 8x - 64 <-- the -8x and 8x cancels out..leaving you with..

= x^2 - 64
