Hello :
f(x) = (x-5)(x+2i)
= x² +2ix -5x-10i
f(x) = x² +(2i-5)x -10i
<span>coefficients : a =1 b = 2i-5 c =-10i</span>

Therefore the answer not rounded is 1.309 radians
Answer:
this is the answer
Step-by-step explanation:
The cost of the path around the swimming pool with length 15m and width 12m is $1,190
<h3>Area of a rectangle</h3>
Pathway with 2m wide:
- Length = 15m + 2m = 17m
- Width = 12m + 2m = 14m
Area of the path = length × width
= 17m × 14m
= 238 square meters
- Cost of the path = $5 per square meter
Total cost of the path = 238 square meters × $5
= $1,190

Answer:
k = 11
Step-by-step explanation:
f(x)=3x+k,
We know the input is -1 so replace x with -1 and the output is 8 so replace f(x) with 9
8 = 3(-1) +k
8 = -3+k
Add 3 to each side
8+3 = -3+3+k
11= k
