r= change in y

chAnswer:

<h2> C. The relationship is not linear. </h2>

Step-by-step explanation:

When the rate of change is constant of one variable is corresponding to the change in the other variable , then the relationship is said to be linear.

The rate of change is given by:-

r= change in y and in x

⇒r= 2-1 and 7 -3=1/4

Also,

⇒r= 5-3 and 18-11=2/7

but 1/4 ≠ 2/7

Therefore, the rate of change is not constant .

Hence, The relationship is not linear.

Answer:

The answer is C) $12\sqrt{2}$ .

Step-by-step explanation:

For a real number $a$ ,

$\sqrt{a} \cdot \sqrt{a} = a$ .

In other words, multiplying a square root by itself gets rid of the square root.

How does this rule apply here?

$24 = 2\times 12$ .

Similarly,

$\sqrt{24} = \sqrt{2}\times \sqrt{12}$ .

That is:

$\begin{aligned}\sqrt{24}\times \sqrt{12} &= (\sqrt{2}\times \sqrt{12}) \times \sqrt{12}\\&=\sqrt{2}\times (\sqrt{12}\times \sqrt{12}) && \begin{array}{l}\text{By the associative property}\\\text{of multiplication}\end{array}\\&=\sqrt{2} \times 12\\ &= 12\sqrt{2}\end{aligned}$ .

Uv = 8 and wx=5 find the missing measure of a rhombus

Harlamova29_29 [7]

Answer:

TU = UV = VW = WT = 8
WX = UX = 5
XV = XT = √39

Step-by-step explanation:

At first we should know the following about the rhombus

1) All sides are congruent

2) The diagonals are perpendicular and bisects each other.

Given UV = 8 and WX = 5

So, according to (1)

TU = UV = VW = WT = 8

And according to (2)

WX = UX = 5

And ΔWXV is a right triangle at ∠x

So, XV² = WV² - WX² = 8² - 5² = 64 - 25 = 39

∴XV = √39

So, XV = XT = √39

So, the missing measure of a rhombus are as following:

TU = UV = VW = WT = 8
WX = UX = 5
XV = XT = √39
