Pentagon ABCDE is a regular polygon. The length of side BC is represented by 3x - 4. The length of side DE is represented by the

dimulka [17.4K]

Answer:

Length of side AB = 5

Step-by-step explanation:

A regular polygon is one in which all angles are equal and all the sides have the same length.

Now, it means that;

AB = BC = CD = DE = AE

We are told that BC is represented by 3x - 4 while DE is represented by the expression 4x - 9.

Thus, from equal length of sides of a regular polygon, we have;

3x - 4 = 4x - 9

4x - 3x = 9 - 4

x = 5

Thus, length of BC = 3(5) - 4 = 15 - 4 = 11

Therefore, Length of AB = 5

Sunscreen is priced at $10.00 per bottle, plus 8% tax. If Sonya purchases a bottle of sunscreen with a $20.00 bill, then what is

MatroZZZ [7]

Answer:

$9.20

Step-by-step explanation:

the tax would be $0.80 because 8% of $10 is $0.80

so the total cost is $10.80

now subtract that by her $20 bill

20-10.80= 9.20

so she will be given $9.20 back in change

Shay works each day and earns more money per hour the longer she works. Write a function to represent a starting pay of $20 with

Masja [62]

Answer:

<u>Function</u>: $p(x)=20(1.04)^x$

<u>Range</u>: option D. 20 ≤ x ≤ 27.37

Explanation:

The function must meet the rule that the pay starts at $20 and it increases each hour by 4%.

A table will help you to visualize the rule or pattern that defines the function:

x (# hours) pay ($) = p(x)

0 20 . . . . . . . . [starting pay]

1 20 × 1.04 . . . [ increase of 4%]

2 20 × 1.04² . . . [increase of 4% over the previous pay]

x 20 × 1.04ˣ

Hence, the function is: $p(x)=20(1.04)^x$

The range is the set of possible outputs of the function. To find the range, take into account that this is a growing exponential function, meaning that the least output is the starting point, and from there the output will incrase.

The choices name x this output. Hence, the starting point is x = 20 and the upper bound is when the number of hours is 8: 20(1.04)⁸ = 27.37.

Then the range is from 20 to 27.37 (dollars), which is represented by 20 ≤ x ≤ 27.37 (option D from the choices).

We will have to find the best option that has a wide wider range of 15 milimeters.

From the images given,

Option A will not be suitable because most of the worms tend towards 30 and 50

Option B is most suitable because most of the worm fall reasonably within this range
