Answer:
77°F
Step-by-step explanation:
C = 5/9 (F - 32)
25 = 5/9 (F - 32)
-----------------------
5/9
45 = F - 32
+32 +32
------------------
77=F
Answer:
use logarithms
Step-by-step explanation:
Taking the logarithm of an expression with a variable in the exponent makes the exponent become a coefficient of the logarithm of the base.

You will note that this approach works well enough for ...
a^(x+3) = b^(x-6) . . . . . . . . . . . variables in the exponents
(x+3)log(a) = (x-6)log(b) . . . . . a linear equation after taking logs
but doesn't do anything to help you solve ...
x +3 = b^(x -6)
There is no algebraic way to solve equations that are a mix of polynomial and exponential functions.

Some functions have been defined to help in certain situations. For example, the "product log" function (or its inverse) can be used to solve a certain class of equations with variables in the exponent. However, these functions and their use are not normally studied in algebra courses.
In any event, I find a graphing calculator to be an extremely useful tool for solving exponential equations.
Yes it is a sin your life matters and god loves you god will take your life away when he wants to if you do subside you go to hell but I just want to let your know that you are loved and I pray that god helps you in any situation you are in the name of Jesus amen
Answer:
15 inches
Step-by-step explanation:
The longest side of the right triangular window frame is 39 inches
The height is 36 inches
Let the base of the window frame be x inches
So according to Pythagoras theorem,
x² + 36² = 39²
x² = 39² - 36² = 225
x =
= 15 inches
The third side of the window frame is therefore equal to 15 inches.
