Answers:
Part A: The value of x must be 0
Part B: The value of x can be any real number
----------------------------------------------------------------
Explanation:
Part A) We have the equation (7^2)^x = 1 which simplifies to 7^(2x) = 1. The only way to get the left side equal to the right side is to have the exponent of 2x equal zero. If 2x = 0, then x = 0. So that's why x = 0 is the only solution here.
--------------
Part B) Similar to part A above, but the exponent is slightly different now. We have (7^0)^x = 1 which turns into 7^(0*x) = 1. The exponent 0*x is really 0 no matter what x is. We can plug in any real number we want for x and the left side will always be 1. This is why the solution set to this equation is the set of all real numbers.
Answer:
60
Step-by-step explanation:
here are 360° used in a whole pie chart
Using proportion
30° → 5 people
360° → 5 × 360 / 30 = 5 × 12 = 60
There are 60 people altogether
Answer:
Step-by-step explanation:
<u>refer</u><u> the</u><u> attachment</u>
let the height be h
since we are given the adjacent side and want to figure out opposite side we'll use tan function
so our equation is
cross multiplication:
by using calculator we acquire:
hence,
about <u>5</u><u>3</u><u>.</u><u>6</u><u>f</u><u>t</u> high in the tree ate monkeys
320-70= 250
250X1/2=125
X=125
