F(x) = x²-4x-5, quadratic function,
Domain (the values if x) is all real numbers.
To find range we should draw a graph or to write an equation in vertex form.
f(x) = x²-4x+4-4-5
f(x) = (x-2)²-9
Point (-2,-9) is the vertex of the parabola, and it is a minimum because a parabola has positive sign in front of x², so it is looking up. Minimum value of y =-9
Range(the values of y) is [-9, ∞)
To find the length of the side of a square when the area is known, find the square root of the area:
Side length = √729
Side Length = 27 feet.
Answer:
8587 should be in the box
Step-by-step explanation:
we would see it question as: 12/- 8587
12 goes into 85 7 times, so 7
12 goes into 18 1 time, so 1
12 goes into 67 5 times, so 5
then the remainder is 7
or you further divide to get . 5 8 3333333...
so your answer should be 715r7 or 715.58333
Answer:
D.2.58
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
That is z with a pvalue of 
, so Z = 2.58.
The answer is given by option D.
