Answer:
sqrt(2x/a) = t
Step-by-step explanation:
X = 1/2at^2
Multiply by 2 on each side
2x = 2*1/2at^2
2x =at^2
Divide by a
2x/a=a/a t^2
2x/a =t^2
Take the square root of each side
sqrt(2x/a) =sqrt(t^2)
sqrt(2x/a) = t
Answer:
-22/3 =x
Step-by-step explanation:
(4x-4) /(x+4) = 10
Multiply each side by (x+4)
(4x-4) /(x+4) * (x+4) = 10 * (x+4)
(4x-4) = 10 * (x+4)
Distribute
4x-4 = 10x+40
Subtract 4x from each side
4x-4-4x = 10-4x+40
-4 = 6x+40
subtract 40 from each side
-4 -40 = 6x+40-40
-44 = 6x
Divide each side by 6
-44/6 = -6x/6
-22/3 =x
Answer:
n = -10
Step-by-step explanation:
1 / 8^n = 8^5^2
We know that 1/a^b = a^-b
We also know that a^b^c = a^(b*c)
8^-n = 8^(5*2)
8^-n = 8^(10)
Since the bases are the same, the exponents are the same
-n = 10
n = -10
-10x -120-11x
combine like terms so -10-11= -21x-120
Answer: 8
Step-by-step explanation:
The formula to find the t-test statistic for differences between in two population mean:-
,where = sample mean difference
SE= Sample error
Given : SE= 4 points
t-statistic = 2.00
Substitute theses values in the above formula , we get
Hence, the sample mean difference is
