Answer:

because

1/2+1/3+1/4

1/2x6+1/3x4+1/4x3

1/12+1/12+1/12

1+1+1/12

3/12

1/4

1:4 so,their is a proability that the problem will be solved.

at the park, people can climb a rope ladder to its top. rosa climbed 2/8 of the up the ladder. Justin climbed 2/6 of the way up

Lerok [7]

Well if you make the denominater of the fraction the same, aka finding the lowest common multiple you can find out so what you do is 8 and 6 both go into 24 8 goes into 24 3 times and 6 goes 4 times so you multiply the numerator by how many times the denominator goes into the LCM(lowest common multiple) and get 6/24 and 8/24 meaning justin climbed higher

Find the height of a cylinder with a volume of 1408 cubic feet and a radius of 8 feet

storchak [24]

Height of cylinder = h = 7.006 feet

Step-by-step explanation:

<u>We are given:</u>

Volume of cylinder = 1408 cubic feet

Radius = 8 feet

<u>We need to find:</u>

Height of cylinder = ?

<u>Formula used:</u>

$Volume = \pi r^2h$

Putting values in the formula and finding height:

$Volume = \pi r^2h\\1408=3.14*(8)^2*h\\1408=3.14*64*h\\1408=200.96*h\\h=\frac{1408}{200.96}\\h=7.006\,\,feet$

So, Height of cylinder = h = 7.006 feet

Let f(x)=e^x and G(x)=x+6. What are the domain and range of g(f(x))?

Lena [83]

Answer:

Domain and Range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively

Step-by-step explanation:

We have the functions, f(x) = eˣ and g(x) = x+6

So, their composition will be g(f(x)).

Then, g(f(x)) = g(eˣ) = eˣ+6

Thus, g(f(x)) = eˣ+6.

Since the domain and range of f(x) = eˣ are all real numbers and positive real numbers respectively.

Moreover, the function g(f(x)) = eˣ+6 is the function f(x) translated up by 6 units.

Hence, the domain and range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively.
