Answer:
x=13+√-13 or x=13-√-13
Step-by-step explanation:
Using the method of completing the square roots:
x²-26x=-13-169
x²-26x=-182
x²-26x+(-13)²=-182+(-13)²
(x-13)²=-182+169
(x-13)²=-13
Take square roots of both sides
(x-13)=√-13
x=13±√-13
That can also be written as
X=13+√13i,13-√13i
Answer:
360360
Step-by-step explanation:
We have the following information:
Number of ways of choosing 5 car models from 15 different models = 15C5
Number of arranging above 5 models = 5!
Therefore, the total number of displayong 5 models would be:
15C5 * 5!
nCr = n! / (r! * (n-r)!)
we replace:
15! / (5! * (15-5)!) * 5! = 15! / 10! = 360360
So there are a total of 360 360 ways to display the 5 car models.
Answer:
I believe that the answer is B,72.

V = pi(r)^2(h)
Answer with pi substitute (3.14):
4 * 4 = 16
3.14 * 16 * 4
V = 200.96
Answer without pi substitute:
4 * 4 = 16
v = pi(16)(4)
v = 64pi
Answer:
Step-by-step explanation:
f(x) = -8x + 20
f(-1) = -8* -1 + 20 = 8+20 =28
5 - 2[f(-1)] = 5 - 2*28 = 5 - 56 = -51
