Answer:
i have no idea just getting points
Step-by-step explanation:
Answer:
First of all, find x from the Pythagorean theorem 
, which c is the hypotenuse.
c=25 or x=25
Next, we have to figure out the value of y and z. So, you need to use inverse trigonometric functions.
arctan
degrees. arctan
degrees.
All in all, the values are
x=25
y=16.3
z=73.7
Hope this helps and have a nice day!
Given that the value of the bought car depreciates by 14%, its value is only 86% of its value from the previous year. With the known equation,
V = P x (1-d)^n
Where V is the current value, P is the original value, d is the depreciation rate, and n is the number of years. Substituting,
V = ($17,440) x (1 - 0.14)^6
= $7055.65
Thus, after 6 years, the car would only be $7055.65.
Answer: -9/6
Step-by-step explanation:
Substitute the value of X and Y into the equation. Therefore
X-2y
When X = -1 and when Y= 4
-1-2(4)
-1-8=-9
Y-2x
When X= -1 and when Y=4
4-2(-1)
When multiplying 2 negatives it becomes a positive so...
4+2=6
-9,6 would be your answers... hope this helps you!!
