Answer:
=7^(-10) or = 1 / 7^10
Step-by-step explanation:
7^(-7)*7^(-3)
Exponent rule : a^n ⋅ a^m = a^n+m
7^(-7)*7^(-3)
= 7^(-7-3)
=7^(-10)
= 1 / 7^10

Answer: Choice A</h3>
- Domain: x > 4
- Range: y > 0
========================================================
Explanation:
We want to avoid having a negative number under the square root. Solving leads to
So it appears the domain could involve x = 4 itself; however, if we tried that x value, then we'd get a division by zero error.
So in reality, the domain is x > 4.
-------------
The range of y = sqrt(x) is the set of positive real numbers. So y > 0 is the range for this equation. Shifting left and right does not affect the range, so the range of y = sqrt(x-4) is also y > 0.
We are dividing a positive number (3) over some positive number in the denominator. Overall, the expression is positive because positive/positive = positive.
Therefore, the range of the given equation is y > 0
-------------
The graph is shown below. We have a vertical asymptote at x = 4 and a horizontal asymptote at y = 0. The green curve is fenced in the upper right corner (northeast corner).
I am pretty sure it is talking about interest and $640 is what you start with, with a 3% interest for 2 years
Answer:
zero
Step-by-step explanation:
Assuming your intended side lengths are {7 cm, 10 cm, 18 cm}, the sum of the short sides is not long enough to connect to the ends of the long side. No triangle can be formed.
