Solve The Following System of equations by graphing<br><br>3x + y = 5<br>x - 4y = 32​
Nostrana [21]

first you convert to slope intercept form

3x+y = 5 is the same as y = -3x+5

x - 4y = 32 is the same as y = 4x-8

then you graph

(starting with the y-intercepts as your first points)

the point where the two lines intercept is your solution.

Find all solutions of the equation in the interval [0,2pi)
irinina [24]

Answer:

{π/4, 5π/4}

Step-by-step explanation:

Tan theta -1=0 could be rewritten as tan Ф = 1.  The tangent function is 1 at Ф = π/4.  As the period of the tangent function is π,

tan Ф = 1 will be true for Ф = π/4 + π, or (5/4)π.

The solution set is {π/4, 5π/4}.

The area of the sector of a circle with a radius of 8 centimeters is 125.6 square centimeters. The estimated value of pi is 3.14
tangare [24]
\bf \textit{area of a sector of a circle}\\\\&#10;A=\cfrac{\theta\pi r^2}{360}\qquad &#10;\begin{cases}&#10;\theta=\textit{angle in degrees}\\&#10;r=radius\\&#10;----------\\&#10;r=8\\&#10;A=125.6&#10;\end{cases}&#10;\\\\\\&#10;360A=\theta\pi r^2\implies \cfrac{360A}{\pi r^2}=\theta\implies \cfrac{360\cdot 125.6}{\pi 8^2}=\theta
