V= 4/3 pi r^
6/2= 3 (radius.)
V = 4/3(pi)(3^3) = 113.0973355
(4k+2)(k-2)/(k^2-4)(2k+1)
=2(2k+1)(k-2)/ (k^2-2^2)(2k+1)
Cancel out 2k+1
2(k-2)/(k-2)(k+2) using a^2-b^2=(a-b)(a+b)
cancel out k-2
2/k+2
Therefore numerator is 2
Answer:
45
sorry if it is not what u needed
Answer:
As per the statement:
Elizabeth claims that the fourth root of 2 can be expressed as 2^m
"fourth root of 2" means
then;
On comparing both sides we get;
Since, it is also given:
Solve for n;
then;
On comparing both sides we get;
Multiply 4 both sides we get;
n = 4
Therefore, value of m and n are and 4
Answer:
90 miles
Step-by-step explanation:
2 hours = work
speed = x
Distance to work = y
y = 2x
y = 3(x - 15)
3 * x = 3x
3 * -15 = -45
y = 2x
y = 3x - 45
Let's graph this (attached below)
We must find the point at which they intercept.
They intercept at (45, 90)
That means that x = 45 and y = 90
So, she is 90 miles from her office.
Let's check our work:
y = 2(45)
y = 3(45) - 45
y = y
y = 90
2 * 45 = 90
3 * 45 = 135
135 - 45 = 90
This proves that y = y and that y = 90.
