Answer:

<h2>The scale factor is 7.</h2>

Step-by-step explanation:

In the image attached, you can observe that both triangles are similar, and we can establish the following proportionality

$\frac{UW}{XZ}=\frac{UV}{XY}=\frac{WV}{ZY}$

Replacing the length of each side, we have

$\frac{2}{14}=\frac{3}{21}=\frac{4}{28}\\\frac{1}{7}= \frac{1}{7}=\frac{1}{7}\\7=7=7$

Therefore, the scale factor between these triangles is 7, that is, ΔXYZ is seven times bigger than ΔUVW

XZ ~ UW
UV ~ XY
VW ~ YZ

Take any corresponding side and the ratio of it is your answer.

Example :

XZ / UW = 14/ 2 = 7
XY / UV = 21 / 3 = 7
YZ / VW = 28 / 4 = 7

Therefore, your answer is B. 7

Answer:

Step-by-step explanation:

(-9)^1/3 * (-81)^1/3

We can rewrite -81 as 9 * -9

So it can be rewritten as:

(-9)^1/3 * (9*-9)^1/3

Since they are all raised to the 1/3, we can combine the bases:

(-9*9*-9)^1/3 =

(9*9*9)^1/3, because the two negatives turn into a positive:

So this is basically:

(9^3)^1/3 = 9^1 = 9

What is the rate of change of the function?

Alona [7]

We have been given that on a coordinate plane a line with negative slope passes through points $(0,1)$ and $(1,-1)$ . We are asked to find the rate of the change of the function.

We know that slope represents rate of change of function.

We will use slope formula to solve our given problem.

$m=\frac{y_2-y_1}{x_2-x_1}$

Let $(x_1,y_1)=(0,1)$ and $(x_2,y_2)=(1,-1)$ .

$m=\frac{-1-1}{1-0}$

$m=\frac{-2}{1}$

$m=-2$

Therefore, the rate of change of the given function is $-2$ .

OK PLEASE HELP ME GUYS I ALWAYS HELP YOU so here it is

gtnhenbr [62]

F=P(1/2)^(t/h)
F=future amount
P=present amount
t=time elapsed
h=legnth of half life

P=96
t=2
h=1
F=96(1/2)^(2/1)
F=96(1/2)^2
F=96(1/4)
F=96/4
F=24 grams

grow by 35%
compound interest
F=P(1+rate)^time
F=95000(1+0.35)^10
F=95000(1.35)^10
F=95000(20.106555868618)
F=1910122.9075187

janice bought her mother a bunch of 10 flowers. two of the flowers are daisies. one half of the remaining flowers are tulips. wr

Paul [167]

2/10, or simplified as 1/5.
Since the part that are daisies is 2, and the total number of flowers is 10, the fraction is 2/10 or 1/5.
