Anwser is 15 beacuse i got the anwser right now
Answer:
4 feet
Step-by-step explanation:
We know the the area of a triangle can be represented as 
.
Since the height is twice the base, we can substitute the value 
in as 
in the expression, making it 
. If the area is 16, we can make the equation
Now to solve for b.
Hope this helped!
Answer:
I think it would be y=4-3x
Step-by-step explanation:
If you're not sure then you always check Desmos it's a graphing calculator
Replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)
f(x)=x-1
y=x-1
x=y-1
x+1=y
x+1=f⁻¹(x)
f⁻¹(x)=x+1
The volume of a sphere is defined as:
V=(4*pi*r^3)/3
then, if we double the radius of the sphere (r=2r):
V=(4*pi*(2r)^3)/3
V=(4*pi*(2^3*r^3))/3
V=(4*pi*r^3)/3*8
Then, the answer is that if you double the radius of the sphere, its volume is increased 8 times.
