Given f(x)=5x 5 and g(x)=6x 1 then what is (f g)(−8)) ?

Answers

Answer 1

Answer: f(x) = 5x+5
g(x) = 6x+1

Just add these functions to find (f+g)(x)

(f+g)(x)=5x+5+6x+1=11x+6

Then substitute -8 for "x" :

(f+g)(-8) = 11 * (-8) + 6 = -88 + 6 = -82

How many square units are in the greatest area that can be enclosed by a rectangle whose perimeter is 20 units?

Answers

In order to have a greatest rectangle, it has to be a square. Because the perimeter is 20 units, the length of 1 side of the rectangle is 20:4=5. Thus, there are 5*5= 25 units could be enclosed in the rectangle. Feel free to ask more :))

Find the value of x when (x+12) 110

Answers

(x+12)=110

Subtract 12 from both sides.

x=110−12

Subtract 12 from 110 to get 98.

x=98

If (x+12) = 110

You would isolate the variable by subtracting 12

(x+12) -12 = 110 -12

Simplify

x = 98

$Answer:y=-(5)/(4)x+8$

This requires y2 - y1/ x2 - x1 as the slope. I got y=-5/4x+8 as my answer

Jack walks 30 miles at 30 degrees north of east, then walks 30 miles at 45 degrees north of east. how many miles east of his starting point will he end up?

Answers

We are given with the distance traveled and the direction
30 miles at 30 degrees north of east
30 miles at 45 degrees north of east
You calculate the horizontal and vertical component using these equations
x = d cos θ
y = d cos θ

where d is the distance traveled

Then, you get the distance from the starting point using the formula
D = √[(∑x)² + (∑y)²]

The answer is
59.47 miles

If a circle has a circumference of C, what is the area of the circle in terms of C?

Answers

First you have to write down the formula on how to get the circumference of the circle (C = 2pi * Radius) and the Area of the circle which is (A=Pi*Radius^2). In getting the radius you need to transform the formula of the circumference by making the radius to be the unknown variable so it would become(R=C/2pi), after that you need to replace the radius in the formula of the area by the transformed formula of the circumference and you will come up of the formula of (A=Pi(C/2pi)^2).
