The formula for the surface area of a sphere is 4πr^2

This can be used in the following way, getting the diameter at 18.3:
18.3/2 = 9.15
Saying PI is 3.14 you can do this:

SA = 4*3.14*9.15^2 = 1051.6 m^2

Formula for volume is:
(4/3)πr^3

V = (4/3)*3.14*9.15^3 = 3207.2 m^3

Use inductive reasoning to describe the pattern. Then find the next two numbers in the pattern. 1, 4, 7, 10, . . .

The reasoning would be that the pattern is going up by 3 every time. 13, 16

What is the solution of log2x+3125 = 3? (1 point)

enot [183]

Answer:

$x = - 1062.5$

Step-by-step explanation:

Assuming the equation is:

$log(2x + 3125) = 3$

Then taking antilogarithms gives:

$2x + 3125 = {10}^{3}$

We simplify on the left to get:

$2x + 3125 = 10 \times 10 \times 10$

This gives us:

$2x + 3125 =1000$

We subtract 3125 from both sides to get:

$2x = 1000 - 3125$

$2x = - 2125$

$x = - 1062.5$

Find the solution of Equation: (3x-2)/(x+3)-1=(3x-3)/(x+1)-2

saveliy_v [14]

Answer:

Solution tends to infinity

Step-by-step explanation:

Given the expression

(3x-2)/(x+3)-1=(3x-3)/(x+1)-2

This can also be expressed as;

(3x-2)/x+2 = 3x-3/x-1

3x-2/x+2 = 3(x-1)/x-1

3x-2/x+2 = 3

Cross multiply

3x-2 = 3(x+2)

3x-2 =3x+6

Collect like terms

3x-3x =6+3

0x = 9

x = 9/0

x = infinity

Hence the expression had no solution. It tends to infinity
