Answer:

The period of function is 5 and amplitude is 3.

Step-by-step explanation:

<em>The period of the function is the time interval after which it repeats itself.</em>

It means the time interval after which the same value of graph is attained.

In the above case looking at the peak point at time 5 seconds, the same value is obtained at time 10 seconds.

Thus the time interval is (10 - 5) 5 seconds.

<em>Amplitude is the maximum value attained by the graph in the complete interval.</em>

In the above case, the maximum value attained is 3.

Answer:

First option: 45x + 20 + 45y

Step-by-step explanation:

The missing options are:

45x + 20 + 45y\\65x + 45y\\45x - 20 + 45y\\\\45x + 65y

 We know that "x" represents the number of weeks Bess worked and "y" the number of weeks Gina worked.

According to the data  given in the exercise, Gina and Bess earn $45 per week for delivering flowers, this is:

45x+45y

Since earned an additional total bonus of $20, then the total money in  in dollars that Bess and Gina earned for delivering flowers can be shown with the following expression:

(45x+20)+45y=45x+20+45y

Notice that this expression matches with the one shown in the first option.

Answer:

m<B = 141 degrees

Step-by-step explanation:

This shape is a heptagon meaning its angles should have a sum of 900 degrees.

we are given the degrees and we need to ad them up

148+90+120+129+130+142=749

then we subtract 749 from 900 which looks like

900-749=141

from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees
