Which three angle measures can be used to make ABC?

Answer: B: 41, C: 68, D: 71.

Step-by-step explanation: A triangle's angles have to add up to 180 degrees for it to be considered a triangle. If you were to add up 71, 41, and 68, then it would equal 180 degrees. This means that out of all the other measurements, these are the three possible angle measures that can be used to make a triangle.

(I figured this out by taking 3 random sides from the list there and adding them up to see if they equal 180.)

Which relations are functions?<br><br><br><br> Choose all answers that are correct.

Hello!

In a function, each input has only one output. In A, three has two outputs, 4 and 5, so A is not a function.

In B, you can use something called the vertical line test to see if each x value has one y value as an output. You move an imaginary vertical line across the graph, and if it intersects with two points it is not a function. If we do this on our graph, it will not intersect two points. Therefore, B is a function.

In C, we can see that each input has one output, or there are all different inputs, so C is a function.

For D we can use that vertical line test again. It intersects both the points (-1,1) and (-1,6) so D is not a function

Our final answers are B and C.

I hope this helps!

Answer:

10.5 minutes

Step-by-step explanation:

Thinking about the problem

The modeling function is of the form P(t)=A⋅Bf(t), where B=4B=4B, equals, 4 and f(t)=\dfrac{t}{10.5}f(t)=

10.5

f, left parenthesis, t, right parenthesis, equals, start fraction, t, divided by, 10, point, 5, end fraction.

Note that each time f(t)f(t)f, left parenthesis, t, right parenthesis increases by 111, the quantity is multiplied by B=4B=4B, equals, 4.

Therefore, we need to find the ttt-interval over which f(t)f(t)f, left parenthesis, t, right parenthesis increases by 111.

Hint #22 / 3

Finding the appropriate unit interval

fff is a linear function whose slope is \dfrac{1}{10.5}

10.5

start fraction, 1, divided by, 10, point, 5, end fraction.

This means that whenever ttt increases by \Delta tΔtdelta, t, f(t)f(t)f, left parenthesis, t, right parenthesis increases by \dfrac{\Delta t}{10.5}

10.5

Δt

start fraction, delta, t, divided by, 10, point, 5, end fraction.

Therefore, for f(t)f(t)f, left parenthesis, t, right parenthesis to increase by 111, we need \Delta t=10.5Δt=10.5delta, t, equals, 10, point, 5. In other words, the ttt-interval we are looking for is 10.510.510, point, 5 minutes.

Hint #33 / 3

Summary

If a person who works 40 hours per week earns $52,000 per year, estimate that person’s hourly wage. Use the estimate that there

oksano4ka [1.4K]

The hourly wage is approximately $26 per hour. Find out how many hours the person works per year by multiplying 40 x 50 to get 2,000 hours. Then divide 52,000 by 2,000 to get the person's hourly wage, which is $26 hours per hour.

Hi there!

First, scientific notation is when you take a number like 15,000 or 0.0015 and turn it into a number that is less than 10 and greater than 1. What you do to make it that is you move that decimal point over to the left or right as needed. So for example, 15,000 would be 1.5 × $10^{4}$ and 0.0015 is 1.5 × $10^{-3}$ .

So if one light year is 5.88 × $10^{12}$ mi. that is just the scientific notation for 5880000000000 mi.

So if you take 5880000000000 mi. and multiply it by 11 then you get 64680000000000

5880000000000 × 11 = 64680000000000 or 6.468 × $10^{13}$

So the answer would be $\boxed{64680000000000}$ or $\boxed{6.468*10^{13} }$
