Hey there,
2 hours = 15 pages
1 hour = 15 / 2
           = 7.5 pages
15 pages = $40
1 page = $40 / 15
            = $2.666666666666667
7.5 pages= $2.666666666666667 x 7.5
               = $20

Hope this helps :))

What is the range of the function graphed?
victus00 [196]
The correct answer is B) 
-3 < y ≤ 3

You can tell this by looking at the graph. The lowest that it goes is -3. You'll also note that the -3 has an open circle, which means that it isn't includes and thus needs a <.

The highest it goes it 3. You'll note that it has a closed circle, which means it is included and needs a ≤.

Evaluate the line integral, where C is the given curve. (x + 4y) dx + x2 dy, C C consists of line segments from (0, 0) to (4, 1)
zubka84 [21]

Parameterize the line segments (call them C_1 and C_2, respectively, by

\vec r_1(t)=(1-t)(0,0)+t(4,1)=(4t,t)

\vec r_2(t)=(1-t)(4,1)+t(5,0)=(4+t,1-t)

both with 0\le t\le1. Then

\displaystyle\int_C(x+4y)\,\mathrm dx+x^2\,\mathrm dy

=\displaystyle\int_0^1\bigg((4t+4t)(4)+(4t)^2(1)\bigg)\,\mathrm dt+\int_0^1\bigg((4+t+4(1-t))(1)+(4+t)^2(-1)\bigg)\,\mathrm dt

=\displaystyle\int_0^115t^2+21t-8\,\mathrm dt=\boxed{\frac{15}2}

How can I use fractions tiles to help divide a whole number by a unit fraction
KonstantinChe [14]
To divide a whole number by a unit fraction, you can always multiply the whole number by the unit fraction's denominator to get the answer! Example: 5 divided by 1/7 is 5*7=35. This answer of 35 makes sense: there are seven 1/7's in a 1, so there are thirty-five 1/7's in a 5.

Jack invested some money in a bank at a fixed rate of interest compounded annually. The equation below shows the value of his in
pochemuha

Answer:

<em>The average rate of change of Jack's investment from the third year to the fifth year is </em><em>$6.43</em>

Step-by-step explanation:

The function that defines the value of his investment after x years,

f(x)=300(1.02)^x

Putting the value of x as 3 and 5, we can get the value of his investment after 3 years and 5 years respectively.

So,

f(3)=300(1.02)^3=318.36

f(5)=300(1.02)^5=331.22

Then,

\text{Average rate of change}=\dfrac{f(x_2)-f(x_1)}{x_2-x_1}

=\dfrac{331.22-318.36}{5-3}

=\dfrac{12.86}{2}

=\$6.43
