Which lines of A, B, and C are perpendicular?

Mathematics
1 answer:
g100num [7]3 years ago
4 0

Answer:

a is perpendicular to both b and c; the product of the slopes a and b or a and c is -1

Step-by-step explanation:

perpendicular slopes multiplied by each other would be -1

-1/3 * 3 for a and both other lines is -1

that means a is perpendicular to both b and c

Which describes how to graph h(x)= -3 squared root x+8 by transforming the parent function?
storchak [24]
The parent function is f(x) = ∛x


When you change the sign to get g(x) = - ∛x you are reflecting the function over the x-axis (because you are changing the sign of all the images).

When you do g(x + 8) to get h(x) = - ∛ (x + 8) you are shifting the functions 8 units to the left.

Therefore, the answer is the fourth option: reflect the parent function over the x-axis and translate it 8 units to the left.

Find the measure of an angle whose complement is five times its measure.
ch4aika [34]

Answer:

The measure of the unknown angle is 15°.

Step-by-step explanation:

Represent this angle by A.  Then the complement of A is 90° - A.

"Angle whose complement is five times its measure" would be expressed as

90° - A = 5A

Solve this for A by adding A to both sides:

90° = 6A.  Then A = 90°/6, or 15°

A line with a slope of 4 passes through the points (8,7) and (7,p). What is the value of p
gayaneshka [121]

Answer:

p=3

Step-by-step explanation:

There are multiple ways to solve this, but since two points are provided (8,7) and (7,p) and the slope is also given (m=4), we can use the formula for the slope.

m = \dfrac{y_2-y_1}{x_2-x_1}

Here,

m=4\quad, (x_1,y_1)=(8,7)\quad,(x_2,y_2)=(7,p)

4 = \dfrac{p-7}{7-8}

Now we'll just solve for 'p'

4 = \dfrac{p-7}{-1}

4(-1) = p-7

-4+7 =p

p=3

Hence, the line passes through (8,7) and (7,3)
