Answer:
And solving we have:
And we can write the expression like this:
The vertex for this case would be:
And the minimum for the function would be 3 and there is no maximum value for the function
Step-by-step explanation:
For this case we have the following equation given:
We can complete the square like this:
And solving we have:
And we can write the expression like this:
The vertex for this case would be:
And the minimum for the function would be 3 and there is no maximum value for the function
Answer: 66 degrees
Step-by-step explanation:
Sum of the angle measures is 180, so:
71 + x + 49 + x + 72 = 180
2x + 192 = 180
2x = -12
x = -6
Meaning the measure of angle A = -6 + 72 = 66 deg.
Answer:
21
Step-by-step explanation:
f(x) =x^2 - 6x + 21
f(xl =0
Answer:
substitute 0 for x
f(0) = 0^2 - 6(0) + 21
0. = 0 - 0 + 21
0. = 21
Answer: It was marked down by 35%
Step-by-step explanation:
1. find the difference of the two prices, 68-44.20=23.8
Take the fraction 23.8/68 (because that is how much the price changed and you need to find what percent that is.
You get 35%
