Answer:
B
Step-by-step explanation:
If you are allowed to use a graphing calculator, this can solve a lot of time. Graphing y = (x - 705)(x - 795) + 800(x - 750)(x - 835) gets us a parabola with x-intercepts of 749.97 and 834.924.
These roots are real and distinct, or choice B.
If you aren't allowed to use a graphing calculator, you can expand and combine like terms to get 801x^2 − 1269500x + 501560475. Looking at the discriminant, we see that (−1269500)^2 - 4*801*501560475 = 4630488100 is greater than 0 and not a perfect square, so it is real and distinct, or choice B.
I hope that helps!
Answer:
6
Step-by-step explanation:
8(1/4) is 2 bc 1/4 of 8 is 2
2-1=.5(10)
.5 works like 1/2 so 1/2 is 10 is 5
then you get 2-1+5 then after that you get 6
Answer:
15 square units.
Step-by-step explanation:
To find the area, we must find the width and length of the rectangle. To find the width and length, we need to find the length of AB and the length of BC. We use the distance formula.
AB: A(-8, 3); B(-3, 3).
= 
= 
= 
= 5
BC: B(-3, 3); C(-3, 6).
= 
= 
= 
= 
= 3
Now that we have both the width and the length, we can solve for the area using A = lw, where A is the area, l is the length, and w is the width. In this case, l = 5 and w = 3.
A = lw
A = 5 * 3
A = 15
So, the area of the rectangle is 15 square units.
Hope this helps!
Answer:
825 people voted in the town of Markston during the elections this year.
Step-by-step explanation:
Hi there!
The total number of people of the town of Markston (1500) is the 100%. Then, the 55% of 1500 can be calculated by multiplying 1500 by 55/100:
55% of 1500 = 1500 · 55/100 = 825
Another way to see this:
If 100% is 1500, then the 55% will be x:
100% -------- 1500
55% ----------- x = 55 · 1500 / 100 = 825
Then, 825 people voted in the town of Markston during the elections this year.
Have a nice day!
Answer:
-16 because the difference in between 10 and -4 is -16
