Answer:

B

Step-by-step explanation:

Look at the graph, it passes to (0,3), so you need to replace that coordinate into A,B,C,D. Then you can see, there is only B and C satisfies.

Y=3(\frac{1}{3} )^{0}=3.1=3.

and

Y=(\frac{1}{2} )^{0}+2=1+2=3

Next step, you can see when x approach to infinite then Y approach to 0.

Hence, we will take limit of B and C, if limit B or C equals to 0 then we will choose.

\lim_{x \to \infty} {3(\frac{1}{3})^x=3. \lim_{x \to \infty} {(\frac{1}{3})^x=3.0=0

and

\lim_{x \to \infty} {[(\frac{1}{2})^x+2]}=  \lim_{x \to \infty} {(\frac{1}{2})^x}+ \lim_{x \to \infty} {2}=0+2=2

We can see that only B is satisfied.

Which side in the smallest triangle would correspond with HI in the largest triangle?
tensa zangetsu [6.8K]

The side of the small triangle that will correspond to the side of HI is side IK.

<h3>How to find corresponding side of similar triangles?</h3>

Similar triangles are triangles that have the same shape but different size.

In similar triangles, corresponding sides are always in the same ratio.

The corresponding angles are equal.

Therefore, the side of the small triangle that will correspond to the side of HI is side IK.

A worker submits the following data on a timesheet: Week 1 — Total hours: 42 (including 4 hrs sick leave, 6 hrs travel) Week 2 —
Assoli18 [71]

Answer:

12.5%

Step-by-step explanation:

In order to find the percentage the worker spent traveling, we can make us of the following ratio:

\frac{number}{ammount}=\frac{percent}{100}

where number is how many hours he spent traveling, ammount is the total ammount of hours he reported and percent is the percentage we want to find. So we can solve the ratio for the percent, so we get:

percent=\frac{number}{ammount}*100%

now, we need to find the total amount of hours he spent traveling, this is gotten by adding the provided data:

6hrs+5hrs=11hrs

next we need to find the total amount of hours reported:

42hrs+46hrs=88hrs

so now we can substitute the data the problem provided us with:

percent=\frac{11}{88}*100%

which yields:

percent=12.5%
