If two lines are perpendicular, which statement must be true? A) The product of their slopes is 1. B) Their slopes are opposites

castortr0y [4]

If two lines are perpendicular, the statement that must be true is : D. The product of their slopes is -1

Lets say that a line has a slope of 2, the line which perpendicular to that line would have a slope of -1/2

Which means, the product would be 2(-1/2) = -1

For a circle with a radius of 6 feet, what is the measurement of the central angle (in degrees) that intercepts an arc with a le

makkiz [27]

Answer:

135 degrees

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=6\ ft$

substitute

$C=2\pi (6)$

$C=12\pi\ ft$

step 2

Remember that the circumference of the circle subtends a central angle of 360 degrees

using proportion

Find out the measurement of the central angle (in degrees) that intercepts an arc with a length of 9π/2 ft

$\frac{12\pi}{360^o}=\frac{(9\pi/2)}{x}\\\\x=360(9\pi/2)/12\pi\\\\x=135^o$

The area of a triangle is 24 square inches. What is the height of the triangle if the base length is 6 inches?

evablogger [386]

I think that it would be 8 inches because to find the area of a triangle is base times height divided by two. So I just doubled the area and divided by 6.

I'm sorry if this is incorrect!
