The prime factorization of the given value is 2 × 2×2×√7
Prime factorization is the number of expressions written as a product of its prime factors.
Given the value 2√112
Prime numbers are numbers that can only be divisible by itself and 1.
2√112 = 2(√2×2×2×2×7)
2√112 = 2(√2⁴×7)
2√112 = 2(2²×√7)
2√112 = 2 × 2×2×√7
Hence the prime factorization of the given value is 2 × 2×2×√7

You can tell they are scaled copies because they retain the same shape as each other, even though they are different sizes. Another way you can tell is to find the measure of all the sides for both shapes and see if the ratio from the original to image is the same for all sides (indicating that all sides were scaled by the same amount)

When graphing data from a study the scale of the data:
A, may make the data misleading
B, should always be presented using a factor of 2.
C, is not important.
D, will not change how the data appears.
Answers
Answer:
B
Step-by-step explanation:
B no steps needed to do this
The scale factor enlarges or reduces the graph of the data set thus it will not change the shape thus option (D) is correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
The scale factor is used to enlarge any data set by the same multiplier.
For example, a coordinate (x,y) will be enlarged by (9x,9y) so 9 will be the scale factor.
The scale factor is useful to work with data which not lie in the range of the given axis in coordinate geometry.
When we apply the scale factor it will either enlarge or reduce the plot size but the shape will remain the same so the data representation will be the same.
Hence "The scale factor enlarges or reduces the graph of the data set thus it will not change the shape".

I = P • r • t
where:
I = interest on the loan
P = principal (loan amount) = $400
r = interest rate = 6% or 0.06
t = time = 60 days or 2/12 months
Substitute the given values into the formula:
I = P • r• t
I = $400 • 0.06 • 2/12
I = $4
Therefore, the student pays $4 in interest if the loan is paid back within 60 days.

We use the nCr combination formula because order doesn't matter.
The number of ways Kyle’s choose eight to attend his birthday party is 43263.
What is a combination?Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements. The number of combinations of n different things taken r at a time, denoted by nCr and it is given by, ⁿCr=n!/r!(n−r)!,where 0 ≤ r ≤ n.
Given that, there are 24 student in Kyle’s kindergarten class.
He choose eight to attend his birthday party
Now, number of ways is
²⁴C₈= 24!/8!(24-8)!
= 24×23×22×21×20×19×18×17×16!/8! 16!
= 24×23×22×21×20×19×18×17/8×7×6×5×4×3×2×1
= 3×23×11×3×4×19×3×17/4×3
= 3×23×11×3×19
= 43263
Therefore, the number of ways Kyle’s choose eight to attend his birthday party is 43263.

What is the slope of the line in the xy plane that passes through the points {-5/2 ,1} and {-1/2, 4}?
Answers
Answer:
m=3/2
Step-by-step explanation:
the line: y=mx+b
This line passes through the points
-> These points (x,y) are on the line
(-5/2,1) : x=-5/2 y=1
1=-5/2m+b
(-1/2,4) : x=-1/2 y=4
4=-1/2m+b
We have a system of equation:
1=-5/2m+b
4=-1/2m+b
After solving this, we have m=3/2 b=19/4
-> The slope is 3/2
