Answer:
<C =10°
Step-by-step explanation:
The sum of angles in a triangle is 180°. Hence,
<C+<D+<E =180
Given
<C =x-4
<D = 11x-11
<E = x+13
Substitute
x-4+11x-11+x+13 = 180
13x-2 = 180
13x =180+2
13x = 182
x = 182/13
x = 14
Get <C
Since <C = x-4
<C = 14-4
<C =10°

Answer:
- a) P(x) = 32000*1.04^x
- b) $37435
- c) During year 7
Step-by-step explanation:
<u>Given</u>
- Initial pay = $32000
- Increase rate = 4%
a. <u>Formula</u>
b. Year 5 is after 4 years, so we are looking for the value of P(4)
- P(4) = $32000*1.04^4 = $37435
c. <u>P(x) = 40000, x = ?</u>
- 40000 = 32000*1.04^x
- 1.04^x = 40000/32000
- 1.04^x = 1.25
- log 1.04^x = log 1.25
- x = log 1.25 / log 1.04
- x = 5.69, this is 6 years after
The required number of the years is 6 + 1 = 7
