Answer:
(a) Coterminal =495, -225
(b) Coterminal = 135,-585
Step-by-step explanation:
The angles are:
(a) 135° (b) −225°
The coterminal angle of angle x is derived by:

Solving (a): 135°
Substitute 135 for x in 

Split


Solving (b): -225°
Substitute -225 for x in 

Split


First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
putting time into years for simplicity,
4 months ÷ 12 months/year = 0.333333 years,
then, solving our equation
I = $ 376.00
I = 18800 × 0.06 × 0.333333 = 375.999624
I = $ 376.00
The simple interest accumulated
on a principal of $ 18,800.00
at a rate of 6% per year
for 0.333333 years (4 months) is $ 376.00.
Answer:
Step-by-step explanation:
Plot the points and connect in pairs.
We got a right triangle.
<u>The legs have the length:</u>
- 1 - (-2) = 3 units and
- 1 - (-3) = 4 units
<u>The area of the triangle is:</u>
- A = 1/2bh
- A = 1/2*3*4 = 6 square unit
2^3=2*2*2=8
⇒ 8+8-7=16-7=9
