2 y = - x - 12 y = x + 5

- x - 1 = x + 5- 2 x = 5 + 1- 2 x = 6x = - 6 : 2x = - 32 y = - 3 + 52 y = 2y = 1The solution is ( - 3 , 1 ).Answer: x = - 3.

The circumference of a circle is 23π m. What is the area, in square meters? Express your answer in terms of \piπ
LenaWriter [7]

Answer:

Area of the circle =   \frac{529}{4}  π  m²    or      132.25 π  m²

Step-by-step explanation:

To find the area, we will follow the steps below.

First write down the formular for the circumference of a circle, then use the formula to find the radius of the circle after which you can now find the area of the circle.

That is;

C = 2πr

where c is the circumference of the circle and   r is the radius of the circle

From the question given, circumference C = 23π

23π = 2π r

Divide both-side of the equation by 2π

23π/2π  =  2πr/2π

23/2   =  r

radius =   \frac{23}{2}  m

Formula for calculating the area of a circle is given by;

A = πr²

where A= area of the circle   and   r is the radius of the circle

A = π ( \frac{23}{2} )²

A = \frac{529}{4}  π  m²    or      132.25 π  m²

Area of the circle =   \frac{529}{4}  π  m²    or      132.25 π  m²

Find sec(x) and csc(x) if tan(x) = 3 and cos > 0
Zielflug [23.3K]

Recall that

1+\tan^2x=\sec^2x\implies\sec x=\sqrt{1+\tan^2x}

We know to take the positive root here because \cos x>0, which means \sec x>0 as well. Then

\sec x=\sqrt{1+3^2}=\sqrt4=2\implies\cos x=\dfrac12

We then have

\tan x=\dfrac{\sin x}{\cos x}=\dfrac{\sin x}{\frac12}=3\implies\sin x=\dfrac32\implies\sec x=\dfrac23
