Vsphere=(4/3)pir^3

d/2=r
d=6,
6/2=3=r

Vsphere=(4/3)pi(3^3)
Vsphere=(4/3)pi(27)
Vsphere=36pi cubic inches

How to solve 2a x a x a x3a + b +4b

kodGreya [7K]

Answer:

$6 {a}^{4} + 5b$

Step-by-step explanation:

$2a \times a\times a \times 3 a+ b + 4b \\ 2a \times a = 2 {a}^{2} \\ 2 {a}^{2} \times a = 2 {a}^{3} \\ 2 {a}^{3} \times 3a = 6 {a}^{4} \\b + 4b = 5b$

Therefore the answer is

$6 {a}^{4} + 5b$

Find the inverse of h(x)=(2x-4)/3

Agata [3.3K]

Answer:

The inverse of the h(x) is $h^{-1}(x)=\frac{3x}{2}+2$ Step-by-step explanation:

Given : Expression $h(x)=\frac{2x-4}{3}$

To find : The inverse of the expression ?

Solution :

Expression $h(x)=\frac{2x-4}{3}$

Let, h(x)=y then $y=\frac{2x-4}{3}$

For inverse we replace the value of x and y and find the value of y in terms of x.

Replace the value of x and y,

$x=\frac{2y-4}{3}$

Solve for y by cross multiply,

$3x=2y-4$

Adding 4 both side,

$3x+4=2y$

Dividing by 2 both side,

$\frac{3x+4}{2}=y$

Therefore, The inverse of the h(x) is $h^{-1}(x)=\frac{3x}{2}+2$

In triangle ABC, a=7, b=3 and cos C = 1/2. The value of c is

aalyn [17]

Answer:

Correct option: 2 -> sqrt(37)

Step-by-step explanation:

To solve this problem, we just need to use the law of cosines. This law is used to find the third side of a triangle, when we have the two other sides and the angle between them.

The equation of the law of cosines is:

c^2 = a^2 + b^2 - 2 * a * b * cos(C)

So, we have that:

c^2 = 7^2 + 3^2 - 2 * 7 * 3 * (1/2)

c^2 = 49 + 9 - 21

c^2 = 37

c = sqrt(37)

Correct option: 2
