Answer:
-0.95
Step-by-step explanation:
Divide the percent by 100 and since you are decreasing it would be a negative.
Okay so.
We have two basic equations
Tower A+ B+720 A is 720ft taller than B.
Tower A+B= 1982 Combined height is 1982ft
Replace A with B+720 in 2nd equation and solve for B
B+720+B=1982 Combine like terms
2B+720=1982 Subtract 720 from both sides
2B=1262 Divide both sides by 2
B=1262/2
B= 631ft
We know that A=B+720 so you simply need to do that addition to have the height of both towers.
Answer:
The domain is (-∞,∞) and range is (k,∞)
Step-by-step explanation:
The graph is given as 
.
When x =0, we have f(x) 
= y intercept
Consider the exponential function y = 
.
This is defined for domain all real numbers and range = (0,infinity) for all positive a.
This function is transformed into our function by horizontal shift of h units to left and vertical units of k units up.
i.e. Y = y-k and X = x-h
Since x has domain as set of all real numbers X also set of real numbers
So domain is (-∞,∞)
Since range of original graph is (0,∞), we have Y minimum value as k and max as infinity.
Range = (k,∞)
5+3r=4+4r
subtract 4 from both sides
1+3r=4r
subtract 3r from both sides
1=r
Answer: 69.3
Explanation: So if the height is 13.1, that means that the length is 2.3. And to find volume, you do length times width times height. So the width would be 2.3 because it is a even square if that makes since. Now 2.3 times 2.3 is 5.29. Now we multiply 5.29 by 13.1. The answer is 69.299. Now we round this to the nearest tenth, so the answer would be 69.3.
