Consider f(x)=2|x|
What is the rate of change over the interval 0≤x≤4?

How is the rate of change over this interval related to the form of the function?

Answers

Answer 1

Answer:

Please check the explanation.

Step-by-step explanation:

As we know that the average rate of change of f(x) in the closed

interval [a, b] is

[tex]\frac{f\left(b\right)-f\left(a\right)}{b-a}[/tex]

Given the interval [a, b] = [0, 4]

as

[tex]f(x)=2|x|[/tex]

[tex]f(b)=f(2)=2\cdot \:4[/tex]       ∵  [tex]\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0[/tex]

      [tex]= 8[/tex]

   

[tex]f(x)=2|x|[/tex]

[tex]f(a)=f(0)=2\cdot \:0[/tex]       ∵  [tex]\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0[/tex]

       [tex]= 0[/tex]

so the average rate of change  :

[tex]\frac{f\left(b\right)-f\left(a\right)}{b-a}=\frac{8-0}{4-0}[/tex]

              [tex]=\frac{8}{4}[/tex]

               [tex]= 2[/tex]

We know that a rate of change basically indicates how an output quantity changes relative to the change in the input quantity. Here, it is clear the value of y increase with the increase of input.

The value of the function f (x) is 15/2 when x = -5 and is -73/2 when x = 3. What is the equation of the function?

Answers

Answer:

y = -5.5x - 20

Step-by-step explanation:

There are many functions that cross those points.

Assuming you're looking at a straight line.

y = mx + b

15/2 = -5m + b  --> 7.5 = -5m + b

-73/2 = 3m + b  --> -36.5 = 3m + b

Subtract the first from the second.

-44 = 8m

m = -5.5

Plugging back into the first equation, we get b = -20

Answer:

f(x) = −11/2x − 20

Emma was about to finish grocery shopping when she noticed that cans of soup were on sale. Her total bill for groceries would be $89.61 if she purchased two cans of soup and $94.98 if she bought five cans. Which equation could be used to describe Emma's grocery bill, B, in dollars as a function of the number of cans, C, purchased?

B(C)=2.69C+84.23

B(C)=1.99C+85.63

B(C)=1.79C+86.03

B(C)=1.07C+87.47

Answers

Answer:

3rd option: B(C)= 1.79C +86.03

Step-by-step explanation:

Total bill

= cost of cans(number of cans) +cost of other groceries

Let the cost of other groceries be G, and the cost of cans be X.

Given that number of cans= C,

Total bill= XC +G

If 2 cans were purchased,

2X+G= 89.61 -----(1)

If 5 cans were purchased,

5X +G= 94.98 -----(2)

(2) -(1):

(5X +G) -(2X +G)= 94.98 -89.61

5X +G -2x -G= 5.37

3X= 5.37

X= 5.37 ÷3 (÷3 on both sides)

X= 1.79

Subst. X= 1.79 into (1):

2(1.79) +G= 89.61

3.58 +G= 89.61

G= 89.61 -3.58 (-3.58 on both sides)

G= 86.03 (simplify)

Total bill

= XC +G

= 1.79C +86.03

Thus, the function is B(C)= 1.79C +86.03.

Answer:

the answer is (C)=1.79C+86.03

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x = [tex]\frac{19}{9}[/tex]

Step-by-step explanation:

First, make all the different parts into fractions with a common denominator, so that you can add and subtract them easily. In this case, the common denominator is four.

Doing this, you get  [tex]\frac{3}{4} x + \frac{8}{4} x = -\frac{1}{4} + \frac{2}{4} x + \frac{20}{4}[/tex]

Isolate all the variables to get [tex]\frac{3}{4} x + \frac{8}{4} x - \frac{2}{4} x = -\frac{1}{4} +\frac{20}{4}[/tex]

Then, combine like terms [tex]\frac{9}{4} x = \frac{19}{4}[/tex]

Multiply both sides by 4 to get 9x=19

Divide both sides by 9, and you get [tex]x= \frac{19}{9}[/tex]

Hope this helps! :)

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that, When Mei was born, her parents gave her 6 dolls to start her collection. Each year, she receives 4 new dolls as gifts.

The function, f(x), models the total number of dolls in her collection after x number of years is,

f(x) =6+4x.

Okay so what you need to understand first is that this is a line right?

So, ask yourself if you know how to graph this line.

If you do graph it, and because this line has a < less than sign it means you shade down but it also means that any point directly on the line won't be a solution because the line is dashed!

There can be many solutions to this line, but only in the solution area/shaded region. This in on the lower right side of the diagonal line that is crossing from almost 2 x-axis to -4 y- axis on the line!

If you would've shown me the list of ordered pairs I would've been able to select the correct ones.

Find the angle measures. Justify your responses.

Given: a||b, m∠3=63

Find: m∠6,m∠7

Answers

Answer:

m∠6 = 117°

m∠7 = 63°

Step-by-step explanation:

It's given that a║b and m∠3 = 63°

Since, ∠3 and ∠6 are the consecutive interior angles,

m∠3 + m∠6 = 180°

63° + m∠6 = 180°

m∠6 = 180° - 63°

        = 117°

Since, ∠3 and ∠7 are the corresponding angles,

Therefore, ∠3 ≅ ∠7

m∠7 = m∠3 = 63°
