It should be A. 0, because any number with a power of 0 should equal 0. I hope I helped!
Answer:
no
Step-by-step explanation:
the punctuation was a little confusing, but heres what i think u meant
"A grocery store is giving a reusable bag to every person who donates more then than 5.00 to charity, Courtney donates 1.25, will she get a bag?"
for this answer we see that x is the amount of money someone donates, so x has to be greater then 5.00, so the mathematical expression would be shown like this
x > 5.00
if x is not greater then 5.00 (like if its equal or less) then the store will not give a new bag, in this case 1.25 is not an amount that x can be
Answer:
a c a b
Step-by-step explanation:
Remark
You'll see it a whole lot easier if you make a substitution so that it looks like something you have already seen
Solution
let y = x^2
x^4 = x^2 * x^2
x^4 = y * y
x^4 = y^2
Now the expression becomes
y^2 + 8 y - 9 = z
(y + 9)(y - 1) = z
Now put the x^2 back in.
(x^2 + 9) ( x^2 - 1) = z
x^2 - 1 becomes x + 1 and x - 1. At this level x^2 + 9 can't be factored.
Answer
(x^2 + 9) (x + 1)(x - 1)
Given that the chords intersect at the center, you conclude that they both are diameters.
Now, you have that the point p is the intersection point, so it is the center of the circle.
Then, the length of CP is the radius of the circle, and also the lenght of PB is the radius.
So, the length of CP is equal to the length of PB, and it is 8.
Answer: 8.
