Answers
Answer:
60°
Step-by-step explanation:
Complementary angles sum 90°
a + b = 90° Eq. 1
b = a/2 Eq. 2
Replacing Eq. 2 in the Eq. 1
a + a/2 = 90
2a/2 + a/2 = 90
3a/2 = 90
a = 90*2/3
a = 60
from the Eq. 2
b = 60/2
b = 30
Check:
from the Eq. 1
60 + 30 = 90

Answer:
Total interest = A - P = $2,223.00
Total amount = $10,023.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 9.5%/100 = 0.095 per year.
Solving our equation:
A = 7800(1 + (0.095 × 3)) = 10023
A = $10,023.00
The total amount accrued, principal plus interest, from simple interest on a principal of $7,800.00 at a rate of 9.5% per year for 3 years is $10,023.00.

(PLEASE ANSWER ILL GIVE YOU 20 POINTS) Determine if the relation is a function. If the relation is a function, find the domain and range.Required to answer. Single choice.
Answers
Answers:
The relation is a function
Domain = {-2, -1, 0, 1, 2}
Range = {-2, 0, 2}
=================================================
Explanation:
The blue points shown are
(-2,-2)
(-1,0)
(0,2)
(1,0)
(2,-2)
Note how the x values do not repeat themselves. Visually this graph passes the vertical line test. It is impossible to draw a single straight vertical line through more than one blue point at a time. It tells us that any x input leads to exactly one y output.
The relation is a function
The domain is the set of x coordinates of the points
Domain = {-2, -1, 0, 1, 2}
The range is the set of y coordinates of each point
Range = {-2, 0, 2}
Toss out any duplicate items that may occur in the range.
Answer:
The relation is a function.
The domains are 2, 1, 0, -1, -2.
The ranges are -2, 0, 2, 0, -2

To find
Coordinates of the image A'B'C' after a reflection over the x-axis
Solution
Rule for reflection over x-axis is
