Radius of circle O has a slope of 2.5. What is the slope of the tangent line to circle O through point A?

1 answer:

6 0

The tangent line is perpendicular to the radius, so will have slope
.. -1/2.5 = -0.4 . . . . . . corresponding to the 3rd selection

netineya [11]

Answer:

Assuming "the speaker takes up 1/6 of the internal volume"

volume is 9³ in³

you want the remaining volume, which is 5/6 of the total

(5/6)9³ = 607.5 in³

double that if you want the remaining volume for BOTH speakers....

Which graph represents the function y = 4?

Temka [501]

Answer:

The first one

Step-by-step explanation:

This is a constant function, i.e. the value for y doesn't depend on x. So, every x value will lead to the same y value, in this case 4.

This implies that the graph is a horizontal line, composed by all points like (x,4), where x can be any value and 4 is fixes as the y coordinate.

Find the slope of the line passing through the points (7, 8) and (-7, 1). Show your work.

anygoal [31]

Answer:

The slope is $\frac{1}{2}$

Step-by-step explanation:

∵ The rule of the slope passing through 2 points is:

m = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

∵ The points are (7 , 8) and (-7 , 1)

∴ m = $\frac{1-8}{-7-7}=\frac{-7}{-14}=\frac{1}{2}$
