The value of y is 5 or -5.
This is because absolute value makes every number positive.

A. What would be the cost of the Standard Daily Rate plus Mileage plan?

Jobisdone [24]

Answer:

Part a) $\$190$

Part b) $\$315$

Part c) Standard Daily Rate plus Mileage plan

Step-by-step explanation:

Part a) What would be the cost of the Standard Daily Rate plus Mileage plan?

Let

y ----> the total cost

x ----> the number of kilometers

we have that

For a Luxury car

$y=70+0.30x$

For x=400 km

substitute

$y=70+0.30(400)$

$y=\$190$

Part b) What would be the cost of the Unlimited Mileage plan?

we know that

The Unlimited Mileage plan for a Luxury car is $105 per day (see the table)

The trip are three days

To find the total cost multiply $105 by 3

$3(\$105)=\$315$

Part c) Which is the better plan?

Compare

$\$190 < \$315$

therefore

For this trip the better plan is the Standard Daily Rate plus Mileage plan

Write using exponential notation?<br> 5.5.2.2.2.2

inna [77]

Answer:

$5 ^{2} \times 2^{4}$

Step-by-step explanation:

Multiplying 5 by itself is the same thing as raising it to the second power:

$5 \times 5 = {5}^{2} = 25$

We multiply 2 by itself two seperate times. That's the same thing as raising 2 to the second power to the second power or in simpler terms raising two to the fourth power:

$2 \times 2 \times 2 \times 2 = {({2}^{2})}^{2} = {2}^{4} = 16$

Since only multiplication is present, we can combine the two terms to get:

$5^{2} \times {2}^{4}$

What is the sum of the measures of the exterior angles in a nonagon? explain

DedPeter [7]

The sum of the measures of all exterior angle in a polygon with n sides is always $360^{\circ}$ .

Nonagon is a polygon with 9 sides. If this nonagon is regular or equiangular, then all interior angle are congruent, and therefore all exterior angles are congruent. Then the measure of each exterior angle is $\dfrac{360^{\circ}}{9} =40^{\circ}$ .
