Mathematics
1 answer:
swat323 years ago
3 0

Answer:

Step-by-step explanation:

<em>L</em> is 2* <em>W</em> so L=2W

perimeter= 2w+2l

plug in whats given to get

perimeter=2w+4w   4w is because L is *2 of W so that makes L=2w

36=6w

36/6=6

6w/6=w

w=6

6*2=12=L

now we have 6*12=72=Area

ValentinkaMS [17]

Answer:

a. 40

Step-by-step explanation:

Given

g(x)=2x and h(x)=x^2+4

(h\circ g)(x)=h(g(x))

(h\circ g)(x)=h(2x)

We plug in 2x into  h(x)=x^2+4.

(h\circ g)(x)=(2x)^2+4

(h\circ g)(x)=4x^2+4

We now substitute x=-3.

(h\circ g)(-3)=4(-3)^2+4

(h\circ g)(-3)=36+4=40

The correct choice is A.

When having the same radius and height what fraction of a cylinder have the same volume as one cone?
trasher [3.6K]

Answer:

1/3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone = 1/3(nr^2h)

n = 22/7

r = radius  

h = height

If the volume of a cylinder is 300, the volume of a cone = 1/3 x 300 = 100

the capacity of a cone is 1/3 that of a cylinder

Write as<br> logarithm with base 4:<br> 4<br> -5<br> 2<br> -4
NeX [460]

Answer:

log_4(256)=4

log_4(1/1024)=-5

log_4(16)=2

log_4(1/256)=-4

Step-by-step explanation:

We want to write a number, x, such that

Log_4(y)=x.

In exponential form that is 4^x=y.

So first number is x=4.

4^4=256 which means log_4(256) is 4 as a logarithm with base 4.

The second number is x=-5.

4^-5=1/4^5=1/1024 which means log_4(1/1024) is -5 as a logarithm with base 4.

The third number is x=2.

4^2=16 so log_4(16) is 2 as a logarithm with base 4.

The fourth number is x=-4.

Since 4^4=256 then 4^-4=1/256 which means -4 as a logarithm with base 4 is log_4(1/256).
