Hello :
<span>f(x)=x²−18x+157
= x²-2(9)(x) +9²-9²+157
= (x-9)² </span>-9²+157
f(x) = (x-9)²+76....(<span>the vertex form of f(x) )
</span><span>Minimum value of f(x): y = 76</span>
Answer:
I believe it would be B.
Step-by-step explanation:
Range: area of variation with real numbers
Also, seeing the quadrant it is in means there are negative numbers. This takes out the possibility of option A.
Find the area of all six rectangular faces of the prism. (A= l x b)
A1: 3.1 x 5 = 15.5
A2: 7.4 x 3.1 = 22.94
A3: 5 x 7.4 = 37
A4: 3.1 x 7.4 = 22.94
A5: 7.4 x 5 = 37
A6: 3.1 x 5 = 15.5
Add all answers together to get your answer of 150.88 cm^2.
Hope this helps!!
The answer is B.
Negative numbers are to the far left if you were using a number line, so -1 to the 3rd power is -1. Everything else is positive. 1/4 is the same as 0.25 which is less than positive 1, positive 8.8 is next and the last would be -5 to the 2nd power which is 25.
