Aneli [31]

Plug in -1 for x and work it ou'

g(-1) = (-1)^3 + 6(-1)^2 + 12(-1) + 8

= -1 + 6 - 12 + 8

= 1

What is the arc measure of abc in degrees

Virty [35]

Given:

The measure of arc AB is (4y + 6)°

The measure of arc BC is (20y - 11)°

The measure of arc AC is (7y - 7)°

We need to determine the measure of arc ABC.

Value of y:

The value of y is given by

$m \widehat{AB}+m \widehat{BC}+ m \widehat{AC}=360$

Substituting the values, we get;

$4y+6+20y-11+7y-7=360$

Adding the like terms, we have;

$31y-12=360$

Adding both sides of the equation by 12, we have;

$31y=372$

$y=12$

Thus, the value of y is 12.

Measure of arc ABC:

The measure of arc ABC can be determined by adding the measure of arc AB and arc BC.

Thus, we have;

$m \widehat{ABC}=m \widehat{AB}+ m \widehat{BC}$

$m \widehat{AB}+m \widehat {BC}=4y+6+20y-11$

$=24y-5$

Substituting y = 12, we get;

$m \widehat{AB}+m \widehat {BC}=24(12)-5$

$=288-5$

$m \widehat{AB}+m \widehat {BC}=283^{\circ}$

Thus, the measure of arc ABC is 283°

In Lucy's coin collection, 15% of the coins are quarters.

stepan [7]

The total number of coins in Lucy's coin collection is equal to 80 coins.

Let the total number of coins be C.

Given the following data:

Percentage of quarters = 15%

Total number of quarters = 12 quarters

To the total number of coins in Lucy's coin collection:

Since the percentage of the quarters in Lucy's coin collection is equal to fifteen percent (15%) of the total number of coins. Thus, we would multiply the total number of coins by 15% and equate it to 12 quarters.

Total number of coins:

$\frac{15}{100} \times C = 12\\\\15C=12 \times 100\\\\15C =1200\\\\C=\frac{1200}{15}$

C = 80 coins.
