Step-by-step explanation:

2/8 + 7/12 =

Solution,

Find the LCM of the denominators

Then,

The LCM is 4*2*3 = 24

The denominator of both the numbers. should be 24. then

2/8*3/3 = 6/24 + 7/12*2/2 = 14/24

Then we will add the answer after the multiplication,

6/24 + 14/24 = 20/24 

The answer = 20/24

A walffle cone has a height of 7 inches and a diameter of 3 inches. What is the volume of ice cram that can be contained within

Anna [14]

Answer:

16.49 cubic inches.

Step-by-step explanation:

Given:

A waffle cone has a height of 7 inches and a diameter of 3 inches.

Question asked:

What is the volume of ice cram that can be contained within the cone?

Solution:

First of we will find the radius ;-

Diameter = 3 inches

Radius, r = $\frac{Diameter}{2} =\frac{3}{2} =1.5\ inches$

As we know:

$Volume\ of\ cone=\frac{1}{3} \pi r^{2} h$

$=\frac{1}{3} \times3.14\times1.5\times1.5\times7\\ \\ =\frac{49.455}{3} \\ \\ =16.485$

Thus, volume of ice cream will be 16.49 cubic inches.

If f(x)=x2+1, then (f∘f)(x)=

PSYCHO15rus [73]

The resulting composite function (f∘f)(x) is x⁴+2x²+2

When a function is written inside another function, it is known as a composite function

Given the function f(x)=x²+1,

(f∘f)(x) = f(f(x))

f(f(x)) = f(x²+1)

This means we will need to replace x with x²+1 in f(x) as shown:

f(x²+1) = (x²+1)²+1

Expand

f(x²+1) = x⁴+2x²+1+1

f(x²+1) = x⁴+2x²+2

Hence the resulting composite function (f∘f)(x) is x⁴+2x²+2
