I dont understand this question, i did the factor of 36x^2 - 49 but I dont understand the second part
Answers
Answer:
a = 6
b = 7
Step-by-step explanation:
Since both 36 and 49 are perfect squares, you can find their square roots which are 6 and 7.
To check to see if it is correct, replace the a with 6 and replace the b with 7, then evaluate the exponents.

If a new data point at 12 is added to the graph, The mean will increase more than the median, but both will increase.
What is Mean and Median?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.
Given a graph with the data points as,
1, 2, 2, 2, 3, 4, 4, 4, 5
Mean = (1 + 2 + 2 + 2 + 3 + 4 + 4 + 4 + 5) / 9 = 27 / 9 = 3
Median = 5th term = 3
When 12 is added, new data set has 10 data points.
1, 2, 2, 2, 3, 4, 4, 4, 5, 12
Mean = (1 + 2 + 2 + 2 + 3 + 4 + 4 + 4 + 5 + 12) / 10 = 3.9
Median = average of 5th and 6th term = (3 + 4) / 2 = 3.5
Hence the correct option is The mean will increase more than the median, but both will increase.

Find the value of x, y, and z in the rhombus below.
Answers
Answer:
Step-by-step explanation:
For a rhombus, the opposite angles are equal:
74=5y+9
5y=65
y=13
For a rhombus, the adjacent angles are supplementary:
74+(z-10)=180
z-10=106
z=116
74+(x+7)=180
x+7=106
x=99
Opposite angles in a paralleogram are equal
5y+9=745y=65y=13And Consecutive angels have sum 180
x+7+74=180x=180-81x=109And

Answers
Answer:
[tex]f(n) = \frac35 5^n[/tex]
Step-by-step explanation:
Let's assume the solution is of the form [tex]f(n) = \alpha k^n[/tex], where [tex]\alpha[/tex] is to be determined on the starting condition, and [tex]k \in \mathbb{R} \ne 0[/tex]
[tex]f(n+1) -5f(n) = 0\\\alpha k^{n+1} -5 \alpha k^n=0\\\alpha k^n (k-5) = 0 \rightarrow k= 5[/tex]
at this point we can use our starting condition to determine the value of [tex]\alpha[/tex]:
[tex]f(1)=3 \rightarrow \alpha 5^1 =3 \rightarrow \alpha =\frac 35[/tex]
Our solution is, thus [tex]f(n) = \frac35 5^n[/tex]

Polygon LMNPQR is shown on the coordinate grid and models the shape of a garden in a park,
Polygon LMNPQR will be dilated with the origin as the center of dilation to create polygon
L'M'N'P/Q'R'. The vertex Q' will be located at (21, 7).
Which rule best represents the dilation?
Answers
Dilation involves changing the size of the polygon
The best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]
How to determine the ruleThe coordinates of vertices Q and Q' are given as;
Q = (6,2)
Q' = (21, 7)
The scale factor of dilation is then calculated as:
[tex]k = \frac {Q'}{Q}[/tex]
So, we have:
[tex]k = \frac {(21,7)}{(6,2)}[/tex]
Factorize
[tex]k = \frac {7/2(6,2)}{(6,2)}[/tex]
Divide
[tex]k = \frac {7}2[/tex]
So, the transformation rule is:
[tex](x,y) \to \frac 72(x,y)[/tex]
Hence, the best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]

If 50% of some number is 75, what is 200% of that same number?
Answers
Answer:
300
Step-by-step explanation:
A percentage is a unit of proportion that represents a ratio.
For this question let the unknown number be represented by the variable x. We know that 75 is 50% of x, or half of x. This means that we can find the unknown number by doubling 75.
75*2=150This means that x is 150. Next, we need to find 200% of 150. 200% of any number is that number times 2. So, to find the final answer we must once again double 150.
150*2=300So, the final answer is 300.
Answer:
Step-by-step explanation:
270
50% equals to 1/2 so 1/2x=75. Times 2 on both sides you get x=135.
So 135 is x and you multiply 135 by 200%. Which get you 270.
