What is the piecewise-defined function that expresses the cost of the order, C(x), in terms of the number of photos ordered, x?

Answer:

See below

Step-by-step explanation:

The values in the table change by $3.80 from one line to the next. Since each change from line to line changes in number of photos by 20, the average cost per photo is $3.80/20 = $0.19. There is apparently a $5.80 -3.80 = $2.00 shipping charge for numbers of photos in the range shown in the table.

Thus, the piecewise function has 3 pieces:

for x < 100: $2.00 + 0.19x

for x < 200: $4.50 + 0.17x

for x ≥ 200: $0.15x

This could be written as ...

C(x)=\left\{\begin{array}{rcl}\$2.00+0.19x&\text{for}&0\le x

the perimeter of a scalene triangle is 14.5 cm. the longest side is twice that of the shortest side. which equation can be used
madreJ [45]
Let a = longest side      <em> (Establishing labels)</em>
let b = shortest side
let c = third side

P = 14.5                <em>     (Given)</em>
a = 6.2
b = 1/2(a)

P = a + b + c
P = 6.2 + 3.1 + c        <em>(Fill in given info in equation)</em>

P = 9.3 + c                <em>(Simplify)</em>

14.5 = 9.3 + c           <em>(Simplify)</em>

c = 14.5 - 9.3           <em>(Solve)</em>
c = 5.2

Hope this made sense!

Hello please help me! There are 3 questions, I will give brainliest!
Shalnov [3]

Answer:

1) There are 13 students in Jerry's study.

2) There are 39 students in Kathy's study.

3) Jerry's study is more trustworthy!

Step-by-step explanation:

1) Jerry's study is the one with the dot plot.

Now, the number of students is calculated by adding the total number of dots in the plot.

We have a total of 13 dots.

Thus, there are 13 students in Jerry's study.

2) Kathy's study is the one with the histogram.

The total number of students is gotten by adding the corresponding number of students on the y-axis for each range of distance on the x-axis.

Total number of students = 9 + 11 + 7 + 12 = 39 students

3) Jerry's study where he used a dot plot is likely to be more trustworthy because it gives exact values of the number of students for each distance represented whereas, Kathy's study where she used a histogram doesn't give exact values but just gives a range of distances for a particular number of people.

What is the slope???​
Natalka [10]

Answer:

0.25

Step-by-step explanation:

formula is y2-y1 / x2-x1

-1.5 - (-3) / 0 - (-6)

-1.5 - (-3) = 1.5

0 - (-6) = 6

1.5 / 6 = 0.25
