I dont understand this question, i did the factor of 36x^2 - 49 but I dont understand the second part

Answers

Answer 1

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.

Given x + y = x ∙ y = 3, determine x3 + y3 ?

Answers

Answer:

Step-by-step explanation:

x³ + y³ = (x + y)(x² - xy + y²)

= (x + y)(x² + 2xy + y² - 3xy)

= (x + y)[(x + y)² - 3xy]

= 3(3² - 3(3)) = 3(0) = 0

Can anyone help me with this?

Answers

Answer:

yes

Step-by-step explanation:

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 rule

The 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=150

This 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=300

So, 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.

f(n+1)=5f(n), where f(1)=3 and n>1

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]

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=13

And Consecutive angels have sum 180

x+7+74=180x=180-81x=109

And

z-10=109+7z-10=116z=126

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.
