The functions r and s are defined as follows. r(x)=2x-2 s(x)=-x^2 find the value of s(r(-3)) (please help!)
swat32

Solving equation s(r(x)) for x= -3, you find as result s(r(-3))=-64

<h3>Solving Equations</h3>

The equations can be solved when you replace the variable x for a given value or find the zero of functions.

The question gives:

                                 r(x)=2x-2

                                 s(x)=-x²

First, you will find r(-3). For this, in the equation r(x)=2x-2, you should replace x for -3. Then,

                                r(x)=2*(-3)-2

                                r(x)=-6-2= -8

Like r(-3)= -8, you should replace x, in s(x), for -8.

                                 s(x)=-(-8)²

                                 s(x)=-64

Hence, s(r(-3)=-64.

Help me please<br> 8. Match each angle pair with the corresponding drawing. Choose the best answer!
sdas [7]

Answer:

1. D

2. B

3.  A

4. C

Step-by-step explanation:

1. Vertical angles are a pair of opposite angles formed by the intersection of lines. Choice D has two lines intersecting, and two opposite angles formed by it.

2. Adjacent angles are two angles that have a common vertex and common side but do not overlap. Choice B is two angles with a common vertex and common side, and they don't overlap.

3. Supplementary angles are angles that add up to 180 degrees/make a straight angle. Choice A has two angles that add up to 180 degrees, and the two angles combined make a straight angle/line.

4. Two angles are called complementary angles if they add up to 90 degrees and form a right angle. Choice C has two angles that form a right triangle, meaning it adds up to 90 degrees.

An amount of 25,000 is borrow for 15 years at 5.5% interest, compounded annually. If the loan is paid in full at the end of that
Airida [17]

Answer: 55,811.91

Step-by-step explanation:

Given

Principal amount is 25,000

Time Period is t=15\ yr

Rate of interest r=5.5\%

Amount in compound interest is given by

\Rightarrow A=P\left(1+r\%\right)^t

Insert the values

\Rightarrow A=25,000(1+\dfrac{5.5}{100})^{15}\\\\\Rightarrow A=25,000(1.055)^{15}\\\Rightarrow A=55,811.91

Therefore, 55,811.91 must be paid back
