Let's say the original radius was "r", so the circumference is 2πr and the area is πr².
Now when you double the radius, the you get a new circle with radius 2r, circumference 2π(2r) = 4πr, and area π(2r)² = 4πr².
Answer:
h(x) = x/5
Step-by-step explanation:
We want to know the value of y to satisfy the given equation. So:
Hence, since h(x) returns the value of y we found before:
Step-by-step explanation:
I think its Domain: -2,-1,3,-5,-8
Range:5,-2,5,-2,-2
Answer:
Option A) y=1000(1.15)^6 2313 bacteria
Step-by-step explanation:
The initial value is 1,000 and the growth factor would be the the 15%.
15% can be rewritten to .15, but you have to have to add 1 for the start to make the equation easier. Thus making the growth factor 1.15
After multiplying 1000(1.15)^6 you will get 2313.06076562 which is simplified to 2,313 bacteria.
Hope this is helpful. :)
6x^2+14x+4
First factor out all numerical factors (=2 in this case)
2(3x^2+7x+2)
look for m,n such that m*n=3*2, m+n=7 => m=6, n=1
2(3x^2+6x + 1x+2)
Factor 3x^2+6x into 3x(x+2)
2( 3x(x+2)+1(x+2) )
factor out common factor (x+2)
2(x+2)(3x+1)
=>
6x^2+14x+4=2(x+2)(3x+1)
