Answer:

Assume you need to find distance CD, between points C(-2, 2), D(4, -4)

<u>Use distance formula:</u>

$CD = \sqrt{(4 + 2)^2+(-4-2)^2} = \sqrt{72} = 6\sqrt{2}$ ≈ 8.5 units

Answer:

C(x1,y1)=(-2, 2), D(4, -4)

D(x2,y2)=(4, -4)

we have

the length of line segment CD

= $\sqrt{(x2-x1)²+(y2-y1)²}\\ \sqrt{(4+2)²+(-4-2)²}=8.48 units$

What is the scale factor from ALMN to AOPQ?

Nitella [24]

Answer:

Step-by-step explanation:

There 2 ways to interpret this problem.

From the info given:

These two triangles are congruent by SSS and congruent triangles have congruent or equal side lengths so the answer have to be 1.

If the triangles are similar, the side lengths form a proportion of that

$\frac{3}{3} = \frac{3}{3}$

So the ratio or scale factor is 1.

Find the IQR for the data set 24, 36, 42, 57, 65

Zielflug [23.3K]

Answer:

Step-by-step explanation:

The median of this data set is 42.

The 1st quadrant is the mean of 24 and 36: 30.

The 3rd quadrant is the mean of 57 and 65, or 61.

Thus, the IQR is the difference between 61 and 30: It is 31.

The polynomial p(x)=7^3-7x-6 has a known factor of (x+1) rewrite p(x) as a product of linear functions

san4es73 [151]

Answer:

$p(x)=(x+1)(x+2)(x-3)$ .

Step-by-step explanation:

Note: The given function is not correct.

Consider the given polynomial is

$p(x)=x^3-7x-6$

It is given that (x+1) is a factor of given function.

Using synthetic division, divide P(x) by (x+1) as shown below.

-1 | 1 0 -7 -6

| -1 1 6

--------------------------------------

1 -1 -6 0

--------------------------------------

Bottom line represents the coefficients of quotient except the last element because it is remainder. So, the given function can be written as

$p(x)=(x+1)(x^2-x-6)$

$p(x)=(x+1)(x^2-3x+2x-6)$

$p(x)=(x+1)(x(x-3)+2(x-3))$

$p(x)=(x+1)(x+2)(x-3)$

Therefore, the function as a product of linear functions is $p(x)=(x+1)(x+2)(x-3)$ .

Giselle graphs the function f(x) = x2. Robin graphs the function g(x) = –x2. How does Robin’s graph relate to Giselle’s? Robin’s

Sergio039 [100]

Answer: First Option: Robin's graph is a reflection of Giselle´s graph over the x-axis.

A reflection of the graph f(x)=y is g(x)=-y. In this case y=x^2, then:
g(x)=-x^2 that corresponds with the Robin's function
