Answer:

I think the answer is 2

Step-by-step explanation:

I it is perpendicular to y=2x-3 then the x value has to be -1 meaning that the x value has to be -2x

so we have Y=-2x+c

We know the Y value is -3 from the co ordinates (0,-3)

so now we have -3=-2x+c

we also know x=0 from the co-ordinates (0,-3)

so we now have -3=-2*0+c

-3=0+c

to make the equation work c has to be -3 meaning that we now have

-3=0-3 which is

Y=-2x-3

What is the measure of o

Helga [31]

Answer:

Step-by-step explanation:

We need the formula for arc length (in radians) to solve this problem. The formula is:

$s=r \theta$

Where

s is the arc length

r is the radius of the circle

$\theta$ is the intercepted angle

In this diagram, we can see that $\theta$ is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20

Also, if we look, we see that the radius is 5 cm, so r = 5

Now, we substitute into formula and find $\theta$ :

$s=r\theta\\20=5\theta\\\theta=\frac{20}{5}\\\theta=4$

This is given in radians, so $\theta$ is 4 radians

D is the correct answer choice.

Can someone help me with this please

ryzh [129]

Answer:

y=4

Step-by-step explanation:

You can ignore the 3 and 6 because this has no y value change(rise over run)

This is a straight horizontal line so the equation is y=4.
