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:
C
Step-by-step explanation:
There are two arcs a major and a minor arc. You should never have to rely on a diagram to get the right answer.
The circumference is 2 * pi * r
r = 6 km
C = 2* pi * 6
C = 12 pi
The arc size is
arc size = 135 / 360 * 12pi
arc size = 3/8 * 12 pi
arc size = 4 1/2 pi = 9 pi /2 km
Answer:
66.67 %
Step-by-step explanation:
As we can see from the figure
We are given a bar graph in which bars represent the number of reserved campsites at a camp ground for one week from Monday to Sunday.
First of all
Lets the count the total number of reservations made by campsites during the week.
Total Number of campsite reservations = 5+3+4+7+26+30+9
Total Number of campsite reservations =84
Now
we have to calculate what percent of reservations were made for friday or saturday.
% of reservations made on friday or saturday = 
% of reservations made on friday or saturday = 
% of reservations made on friday or saturday = 
% of reservations made on friday or saturday = 66.67 %
So in total 66.67 % reservations are on friday and saturday.
