X^2 +2x +10 = 0
D = 4 -40 = - 36
x_1,2 = (-2 +/- sqrt(-36))/2 = (-2 +/- 6i)/2 = 2(-1 +/- 3i)/2 = -1 +/- 3i
x_1,2 = -1 +/- 3i or more understandably
x_1 = -1 -3i and x_2 = -1 +3i
hope this will help you

Answer:
5.1% (nearest tenth)
Step-by-step explanation:
<u>Annual Compound Interest Formula</u>

where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- A = $2,209
- P = $2,000
- t = 2 years
Substitute the given values into the formula and solve for r:







Therefore, the annual interest rate is 5.1% (nearest tenth)

Answer:
5≤x≤7
Step-by-step explanation:
For a given function f(x), the average rate of change in a given interval:
a ≤ x ≤ b
is given by:

Here we have:
f(x) = 4*log(x + 2)
And we want to see which interval has the smallest average rate of change, so we just need fo find the average rate of change for these 4 intervals.
1) 1≤x≤3
here we have:

2) 5≤x≤7

3) 3≤x≤5

4) −1≤x≤1

So we can see that the smalles average rate of change is in 5≤x≤7
