Answer:
(3,16)
Step-by-step explanation:
Factor the equation to find out that the roots are 7 and -1. The vertex's x will be in the center of these two points, so the center point between 7 and -1 is 3. Continue to substitute the x in the equation with 3 to get the other coordinate for vertex.
Answer:
9.00 square units
Step-by-step explanation:
The width of the interval is 4 − 0 = 4. Divided by 4 equal subintervals, the width of each subinterval is 4/4 = 1.
The subintervals are:
0 ≤ x ≤ 1
1 ≤ x ≤ 2
2 ≤ x ≤ 3
3 ≤ x ≤ 4
MRAM is midpoint rectangular approximation method. So we use the midpoints of each interval to find the height of the rectangle:
f(0.5) = (0.5)² − 4(0.5) + 5 = 3.25
f(1.5) = (1.5)² − 4(1.5) + 5 = 1.25
f(2.5) = (2.5)² − 4(2.5) + 5 = 1.25
f(3.5) = (3.5)² − 4(3.5) + 5 = 3.25
So the total approximate area is:
A = 3.25 + 1.25 + 1.25 + 3.25
A = 9.00

I think the answer is 1 for every 4
Answer:
Part A) The percentage increase was 
Part B) Michael is financially better off this year than last year
Step-by-step explanation:
Part A)
we know that
Using proportion
Let
x-----> the percentage increase
Part B) Compare the percentage increase with the inflation
The percentage increase is greater than the inflation
therefore
Michael is financially better off this year than last year
So the step process for this is to factor it out so this is a complex trinomial so u will have to multiply 2 by -9 and the rest should be in your notes .
then once u factor it out you rearrange those two factored brackets and example of this would be
(x+3)(2x+1)
so x+3=0
therefore x=-3. you bring the 3 over to where the zero is and change the sign
for 2x+1=0
2x=-1
2x/2=-1
x=-1/2
so for this one you isolate for x and in order to get rid of 2x you divide by 2 for both
