Answer:

For this equation to be true, a must = 13 and b must = 10 + 2i.

Step-by-step explanation:

First combine the numerators:  3 + 5 + 2i + 2, or 10 + 2i.

Next, multiply the denominators:  4 + 9 = 13

Then rewrite the original equation as:

10 + 2i      a

---------- * ---- = 1

    13        b

For this equation to be true, a must = 13 and b must = 10 + 2i.

Does this graph represent a function? Why or why not?
vlabodo [156]

Answer:

A

Step-by-step explanation:

In order for a graph to be a function, it has to only cross the vertical (up and down) lines that it covers once. Since this is an angle, it crosses all the lines in two different places, and isn't a function.

Please i need help on my math
Kamila [148]

Answer:

V = \pi (2.5)^2h

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

V = \pi (2.5)^2h

Need help fast, being timed!!

Answer:

Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.

Step-by-step explanation:

From given scatter plot, we see that upper quartile of Mrs. Cai's class = 4

lower quartile of Mr. Roland’s class = 4

Both are equal so that means.

That means Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.


Hence last choice is correct.

Jillian measured the distance around a small fish pond as 27 yards. Which would be a good estimate for the distance across the p
DochEvi [55]
Assuming the fish pond is round, what you're given is the circumference.
So you know that 2<span>πr = 27.
We want to solve for the diameter, or d = 2r. We should isolate that.
2r = 27/</span><span>π
2r = 8.59 yards, or ~9 yards.</span>
