WILL GIVE BRAIN AND 100 POINTS NEED HELP ASAP PLZZZ !!!! Suppose a parabola that has its vertex at (0, 0) opens to the left on t

he coordinate plane and the distance from the focus to the vertex is p. Collin says that the equation √(x+p)^2+(y−0)^2=p−x could be used to relate the distance between the point (x, y) on the parabola and the focus, and the distance between the point on the parabola and the directrix. Examine the equation to determine whether Collin is correct. If so, explain why. If not, correct his equation to match the parabola that was described.

Answer: 65000$ worth of things

This is edited, because I got it backwards last time.

We need to make 2500, but she only makes 4% of whatever she sells.

That means the equation is

2500 = 0.04x

Now, we just need to divide both sides by 0.04 and we get 65000.

Sorry for the confusion.

Help me i beg u plzzzz
Ainat [17]
We can say at month 0 she was 43 inches tall.

And at month 18 she was 52 inches tall.

We can say that x is the number of months and y is her height.

Rise/run
y2-y1/x2-x1
52-43/18-0
9/18
1/2

So the slope is 1/2 (which is what you are looking for.) and if you were to write an equation it would be y=1/2x+43

Brainliest my answer if it helps you out?

Given sin theta = 2/5 and 0 theta 90 find sin 2 theta
Liono4ka [1.6K]

Given:  sin theta = 2/5.  This tells us that the lengths of the opp side and the hyp are 2 and 5 respectively.  The adj side is found using the Pyth. Thm.:  5^2-2^2= 25-4 = 21, so that the adj side is sqrt(21).

The double angle formula for the sine is sin 2theta = 2 sin theta *cos theta.

In this particular problem, the sine of 2theta is 2*(2/5)*[sqrt(21) / 5], or:

                                                                              (4/25)*sqrt(21).
