To evaluate the expression of m=4 and n=9, you would replace the variables (n and m) with the corresponding numbers. Giving you this equation: 9+5(4).
9+20 once simplified. 29 is your final answer.

PLZ, HELP WILL GET BRAINLIEST AND A LOT OF POINTS.
TEA [102]

Answer:

y=2(4^x)

Step-by-step explanation:

if you notice, all the y-values are multiplied by 4 for each x-value. this means 4 is raised to the power of x. however, when you plug this in, you realize that the value produced is only half the actual y-values, so you multiply this whole thing by 2.

y=2(4^x)

Answer:

Do you know the cylinder volume formula?Answer is: V=Pi*r^2*h Let me explain what that means. So the Pi is a constant number equal to 3.14..... and continue and this doesn't effect the volume while radius and height are the ones who do that.The volume is more effected by the radius because if both of them are a same number the radius would be greater than the height.

If r= 2 and h=2 than V=Pi*2^2*2 V=3.14*4*2

Step-by-step explanation:

Let me solve the problem!

a) r=3 h=10 than V=Pi*3^2*10 V=Pi*9*10 V=90Pi

When we increase the raduis by 1

b)r=4 h=10

V=Pi*4^2*10 so V=Pi*16*10 so V=160Pi

c)r=3 h=11

V=Pi*3^2*11 so V=Pi*9*11 so V=99Pi

It meas that when the radius is increased by 1inc the volume is greater than when you increase the height by 1.

Thank!
