Answer:
No.
Step-by-step explanation:
A circle is defined as a figure in which all points are equidistant from the center, or C. In order to determine how far points A and B are from the center, we must first find the difference in positioning from (2,5) to each point and then use Pythagorean Theorem to calculate the length of the hypotenuse. Point A establishes that the radius of the circle must be 10 units, and Point Bis only about 8 units away.
Answer:
You would need 2.5
Step-by-step explanation:
You can use a porportion to solve.
(cross multiply and solve)
Answer:
2s+5p=40
Step-by-step explanation:
s=sodas
p=popcorn
you can plug in 0 for s or for p to see how many of the other she can get (if you plug in 0 for s you see she can get 8 popcorns, if you plug in 0 for popcorn, she can buy 20 sodas)
69 out of 100 because if you turn 3/10 into a fraction with a like denominator as 39/100 you get 30/100 and then you add 39 and 30 and get 69/100
Answer:
Let y=x² . Then:
x4−10x2+9=y2−10y+9
y²-10y+9=(y-9)(y-1)
Substitute x² for y:
x4−10x2+9=(x2−9)(x2−1)
x²-9=(x+3)(x-3)
x²-1=(x+1)(x-1)
x4−10x2+9=(x+3)(x−3)(x+1)(x−1)
