X = 2V6 + 4 or x =-2V6 + 4
Answer:
10s²-6s+9
Step-by-step explanation:
C = -3 + 5s²
B = -2s + 5
2(-3 + 5s²) = -6 + 10s²
3(-2s + 5) = -6s + 15
10s² - 6s + 9
You haven't shared all of the question, so I'll guess that you want to find "how fast is the area of the sphere increasing?"
Area of a sphere = 4*pi*r^2
Rate of change of area of a sphere with respect to radius r:
dA/dr = 8*pi*r*(dr/dt)
Here, that would come out to
dA/dr = 8*pi*r*(2 inches / sec)
If you meant, "how fast is the volume of the sphere increasing?" you'd need to use a different equation:
V = (4/3)*pi)*r^3
and go through a similar process.
Answer:
C and E
Step-by-step explanation:
JUST MULTYPLY:):):)
So pemdas
parenthasees first
do inner first to outer
(4+6) is innermost
4+6=10
and
(24-17)
24-17=7
we now have
{[3 times 10]-8}+[4 times 7]
we do the multilication
3 itme s10=30
4 tim es7=28
now we have
{[30]-8}+[28]
addition
{22}+[28]
22+28=50
the answer is 50
