Given the definitions of f (x) and g(x) below, find the value of (gof)(-8).
f(x) = -x + 8
g(x) = x2 – 3x+2

Answers

Answer 1

Answer:

(gof)(-8) = 210

Step-by-step explanation:

(gof) = (-x + 8)² - 3(-x + 8) = 2

        = x² - 16x + 64 + 3x - 24 + 2

        = x² - 13x + 42

(gof)(-8) = (-8)² - 13(-8) + 42

             = 64 + 104 + 42

             = 210

An angle measures 38° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

One angle is 26 degrees and the other is 64 degrees.

Step-by-step explanation:

Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:

90 = (x-38) + (x)

52 = 2x

26 = x

This means that one of the angles is 26 degrees, and the other is 64 degrees.

Answer:

[tex] y = \frac {1}{2}x +2[/tex]

Step-by-step explanation:

Line is passing through the points (0, 2) & (2, 3)

Slope of line = (3 - 2)/(2 - 0) = 1/2

Equation of line in point slope form is given as:

y - 2 = 1/2(x - 0)

2(y - 2) = x

2y - 4 = x

2y = x + 4

[tex] y = \frac {1}{2}x +\frac {4}{2}[/tex]

[tex] y = \frac {1}{2}x +2[/tex]

is the required equation of blue line.

Answer:

2y-4 =x

Rearranged as:

2y = x + 4

x = 2y - 4

y = x/2 +4

Actually Welcome to the Concept of the Volumes.

Volume = base area * Height

hence, here,

base area = 1/2(3)(4)

base area = 6 sq. inches,

now volume = 6 * height

==> Volume = 6*11 = 66 cubic inches

====> hence the volume of the triangular prism is 66 cubic inches.
