What is the length of PR?

d.9 is the length

The reason is because as we have 2 triangles and 21 is divided by 3 we have proof that 27/3=9.

Hope I helped!

You can use deductive reasoning for this. The angle measures are the same so they are similar triangles. This means that they are proportionate. Because the smaller left side is 1/3 the amount of the bigger one, you can assume that the other side follows the same pattern. The smaller side would be 1/3 the size of the bigger side and 1/3 of 27 is 9.

Which is the graph of f(x)=2(3)^x

likoan [24]

Let's plug the values and see which couple satisfy the equation: since $y = 2\cdot 3^x$ , if we plug the values from the first option $(x,y)=(1,6)$ we have

$6 = 2\cdot 3^1 = 2\cdot 3$

which is correct.

If we plug the values from the second option $(x,y)=(1,9)$ we have

$9 = 2\cdot 3^1 = 2\cdot 3$

which is not correct

If we plug the values from the third option $(x,y)=(2,9)$ we have

$9 = 2\cdot 3^2= 2\cdot 9$

which is not correct

If we plug the values from the fourth option $(x,y)=(2,12)$ we have

$12 = 2\cdot 3^2= 2\cdot 9$

which is not correct

So, the answer is the first one.

Ann has to make payments twice a year on her health insurance. If each payment is $2,316, how much money should she budget for h

siniylev [52]

Answer:

$386

Step-by-step explanation:

If Ann has to pay $2316 twice a year

(every 6 months), then, we calculate

$2316/6 = $386 every month.

Hence, Ann's budget for health

insurance each month is $386.

Hope it helps!

6 A U 3 3 1 2 3 What is the equation of the line in slope-intercept form? The equation of the line is

AleksandrR [38]

Answer:

$y = -\frac{5}{4} x+5$

Step-by-step explanation:

1) First, find the slope of the line by using two points on the graph. We can see that (0,5) and (4,0) are clearly marked on the line, so let's use those points. Use the slope formula $m = \frac{y_2-y_1}{x_2-x_1}$ and substitute the x and y values of those points into it, then simplify:

$m =\frac{0-5}{4-0} \\m = \frac{-5}{4}$

So, the slope is $-\frac{5}{4}$ .

2) Now, identify the y-intercept on the graph. The y-intercept is the point at which the line intersects the y-axis. By reading the graph, we can see that the line intersects the y-axis at (0,5), so that must be the y-intercept.

3) Substitute values for $m$ and $b$ in the slope-intercept formula, $y = mx + b$ , to write the equation of the line. Since $m$ represents the slope, substitute $-\frac{5}{4}$ for it. Since $b$ represents the y-intercept, substitute 5 in its place. This gives the following answer and equation in slope-intercept form:

$y = -\frac{5}{4} x+5$
