Answer:
2x^2(root13)
Step-by-step explanation:
52 factors into 13 (prime number) and 4 (perfect sqare)
this means we can take the root of 4 and bring it outside to become a 2
x^4 is a perfect square and is x^2 squared.
so then we have a 2 and x^2 on the outside and a 13 on the inside.
Answer: 44.9 ft
Explanation: 5.6/8.1=0,6913 65•0,6913=44,94 ft
See the image.
y = -3x - 2
Since a < 0 we have a decreasing line, so it can be only the first or the last
And if we solve the equation for y = 0 we have
0 = -3x - 2
3x = -2
x = -2/3
So, the last one is the right
1.8 ; 11.8 ; 4.18
Given the data:
X : 2.4,1.6, 3.2,0.3, 1.5
Mean, m = Σx / n
Σx = 9 ; n = 5
m = 9 /5
m = 1.8
If data is increased by 10:
X : 12.4, 11.6, 13.2, 10.3, 11.5
Σx = 59 ; n = 5
m = 59 /5
m = 11.8
If data values is doubled :
X : 5.76, 2.56, 10.24, 0.09, 2.25
Σx = 20.9 ; n = 5
m = 20.9 /5
m = 4.18
11^-2 = 0.0082644628
11^-1 = 0.0909090909
11^0 = 1
11^1 = 11
11^2 = 121
