Answer:

$3m^4 - 2 + 8 = 3(m^4 + 2)$

Step-by-step explanation:

Given

$3m^4 - 2 + 8$

Required

Simplify

$3m^4 - 2 + 8$

Subtract 2 from 8

$3m^4 - 2 + 8 = 3m^4 + 6$

Factorize

$3m^4 - 2 + 8 = 3(m^4 + 2)$

The expression cannot be further simplified;

Hence;

$3m^4 - 2 + 8 = 3(m^4 + 2)$

Find the equation of the line that is perpendicular to y = 1/4 x – 2 and passes though the point (5, –2).

zlopas [31]

$\textsf{Let y = ax + b the line we want to find.}$

$\textsf{We know that the slope of y = ax + b is the inverse of the slope of } \mathsf{ y = \frac{1}{4}x - 2.}$

$\textsf{Thus:}$

$\mathsf{a = \dfrac{1}{\frac{1}{4}} = 4}$

$\textsf{As y = 4x + b passes thought (5, -2):}$

$\mathsf{-2 = 4 \cdot 5 + b \Rightarrow 20 + b = -2 \Rightarrow b = -22}$

$\textsf{Hence the line y = 4x - 22 is perpendicular to }\mathsf{y=\frac{1}{4}x - 2}\textsf{ and passes for the point (5, -2).}$

What is the area of the given sector

Romashka-Z-Leto [24]

Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.

Then, using the circle area formula, the area of the 1/9 circle would be:
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57

PLZ HELP! I will give brainliest! A theater can hold 160 giants or 240 elves. If 100 giants are inside, how many elves can also

slava [35]

Answer:

150

Step-by-step explanation:

100 : 160 :: e : 240 proportion

160e = (100)(240)

160e = 24000

elves = 150
