Step-by-step explanation:
Part 1:
Rotation counterclockwise 90 °ree; of a point is
Here is a table of the transformation of all four points:
P(-7,0)-> P'(-0,-7) =P'(0,-7)
A(-4,2)-> A'(-2,-4)
R(-3,0)-> R'(0,-3)
K(-6,2)-> K'(-2,-6)
The initial and rotated images are shown attached.
Part 2: it needs to be done with the technology tool that you have. We can check your work if you post what you did.
(x,y)—>(-y,x)
A’(1,0) B’(-3,0) C’(2,3)
Hope this helped :)
Answer:
$16,534.95
Step-by-step explanation:
To compute interest on loans, we use the compounded interest equation. We use the equation
where
- P is the principle or starting value
- A is the total amount after interest and a period of time
- r is the rate at which interest gathers as a decimal
- n is the number of times compounded in a year.
For this problem, we know P=$8000, r=19%=0.19, t=4 years and n=2. We substitute into the formula and simplify to find the total amount A.

Answer:
See below
Step-by-step explanation:
Graphing all three equations can be done on one DESMOS plot, but it gets very busy and cluttered. The attached image demonstrates an approach that simplifies the graph.
Enter the three equations and three inequalities separately into six DESMOS input boxes. Then I clicked off the color circles of the ones I didn't want to see, leaving only two visible at one time. Each pair represents one line of the function and limit for that function. Then find the intersection point for the values indicated in the second half of the equation.
One can also calculate the answers:
a) (-21,442)
b) (-4,-1)
c) (18,15.5)
d) (20,17)
