Step-by-step explanation:

The formulas we need are below:

C=dπ

A=r²π

d=2r

Plug in the values.

d=12

C=12π

A=36π

C=12(3.14)=37.68

A=36(3.14)=113.04

mezya [45]

This boils down to simple algebraic manipulation.

f'(x)=2x\implies\dfrac{f'(x)}2=x\implies\dfrac{xf'(x)}2=x^2=f(x)

So one possible ODE (the simplest, in fact) is

f'(x)=\dfrac2x f(x)

Digiron [165]

Answer:

d= 8.6 ft

Step-by-step explanation:

In similar triangles, the corresponding sides are in proportion.

\boxed{\dfrac{AW}{MZ}=\dfrac{AJ}{MJ}=\dfrac{WJ}{ZJ}}

To find the value of x,

\dfrac{AJ}{MJ}=\dfrac{WJ}{ZJ}\\\\\\\dfrac{6}{7}=\dfrac{d}{10}\\\\\\\dfrac{6}{7}*10=d

d = 8.6 ft

Answer:

a=11

Step-by-step explanation:

3/a + 5/2a = 1/2

Determine the range

3/a +5/2a = 1/2 , a=0

Write all numerators with common denominators above 2a

11/2a = 1/2

11/2a = 1/2 Simplify the equation using cross-multiplication

22=2a Switch sides of the equation

2a=22 divide both sides of the equation by 2

a=11 is your answer
