Your answer would be A because $4800 is your starting number and it increases 2% every year. How much is it in 20 years?

You use the formula ab^x
a is your starting number
b is the percentage
x is always the length of time

Since you are increasing and trying to get its worth larger than what it was before you use a number larger than one hundred percent in this case the number would be 1.02.


Y=4800(1.02)^20
Y=$7132.55

A square with side x, is changing with time where x(t)=3t+1. What is the formula for the rate of change of the area of the squar
lawyer [7]

Answer:

  A' = 6(3t +1)

Step-by-step explanation:

The area is the square of the side length, so ...

  A = (3t +1)²

The derivative with respect to t is then

  A' = 2(3t +1)·(3) = 6(3t +1)

If you like, you can multiply out the area expression first, then differentiate.

  A = 9t² +6t +1

  A' = 18t +6

This can be factored, if you like, to ...

  A' = 6(3t +1)

What is the slope of the line 6x + y = 24?
ValentinkaMS [17]

Answer:

-6

Step-by-step explanation:

You need to get it in Point-Slope form, or

y = mx + b

Isolate y by subtracting 6x

You are left with:

y = -6x + 24

M is the slope, so in this case, it is -6

Ben uses a compass and a straightedge to bisect angle PQR, as shown below: The figure shows two rays QP and QR with a common end
maria [59]

Answer:

The correct option is;

∠AQS ≅ ∠BQS when AS = BS

Step-by-step explanation:

Given that AQ is equal to BQ. When AS is drawn congruent to BS, we have;

QS is congruent to SQ by reflective property

Therefore;

The three sides of triangle QAS are congruent to the three sides of triangle QBS, from which we have;

∠AQS and ∠BQS are corresponding angles, therefore;

∠AQS ≅∠BQS because corresponding angles of congruent triangles are also congruent.
