Answer:
x Square root 5x
Step-by-step explanation:
Okay, well for a right triangle with legs a and b and hypotenuse c we have:
a2+b2= c2
since we know the hypotenuse (c), we have:
a2+b2= 25
since the short leg is 1 inch shorter than the longer leg,
we can say that a = b-1
So now we have:
(b-1)2+ b2 = 25
b2 - 2b +1 +b2 = 25
2b2-2b -24 = 0
2(b2-b-12) = 0
b2-b-12 = 0
(b-4)(b+3) = 0
Because you can't have a negative length, b = 4
If b = 4, then a = 4-1 = 3
So,
b=4
a=3
Answer:
g(x)=3^-2x
g(x)=9^-x
g(x)=(1/9)^x

Hope this helps!
I "believe" its 0.67 or 0.667
I might be wrong so just wait for other answers.
This question can be solved using a ratio.
3/5 : 3/20
x : 1
x/1 = (3/5) / (3/20)
x = (3/5) x (20/3)
x = 4 miles
