What is a negative 3 cubed written as a fraction
Advocard [28]
When you have an exponent that is negative, it means to take reciprocal of the fraction then take it the power.

Some examples:

5^-2 = 1/5^2 = 1/25
10^-3 = 1/10^-3 = 1/1000

If this answer wasn't clear enough, just comment below or DM me a message!

Please help guys need help

Answer:

A) slope = 20.

B)  The slope of 20 dollars per hour means that for every hour, the price of the service call increases by 20 dollars (or you could say the price of the service call is 20 dollars every hour, both work.)

Step-by-step explanation:

Recall that slope is y2 - y1 / x2 - x1.

Excellent. We are provided with two points: (1, 60) and (3, 100). Let’s enter this into our formula.

Slope = (100 - 60) / (3 - 1) = 40 / 2 = 20.

Now, to determine what the slope means, we can look at the axis titles on the graph. The x axis title is hours, or time in hours. The y axis title is price of the service call in dollars. Therefore, the slope is price (in dollars) per time (in hours).

This can be restated as: The slope of 20 dollars per hour means that for every hour, the price of the service call increases by 20 dollars (or you could say the price of the service call is 20 dollars every hour, both work.)

Hope this helps!

Use the given transformation to evaluate the integral.
GuDViN [60]

For the transformation

\begin{cases}x=7u+v\\y=u+7v\end{cases}

the Jacobian is

\dfrac{\partial(x,y)}{\partial(u,v)}=\begin{bmatrix}7&1\\1&7\end{bmatrix}

with determinant

\det\left(\begin{bmatrix}7&1\\1&7\end{bmatrix}\right)=48

The vertices of the triangle in the u,v-plane are

(x,y)=(0,0)\implies(u,v)=(0,0)

(x,y)=(7,1)\implies(u,v)=(1,0)

(x,y)=(1,7)\implies(u,v)=(0,1)

Then the integral is

\displaystyle\iint_R(x-8y)\,\mathrm dA=-48\int_0^1\int_0^{1-v}(u+55v)\,\mathrm du\,\mathrm dv=\boxed{-448}

Plz help me!!!<br><br> find the value of {3-2(3-4)^3}^3
maxonik [38]

Answer:

-226,981

Step-by-step explanation:

This is how you do it.

First, you do 3-2 which is 1.

Then, you do 3-4 to the 3rd power which is -61.

After, you do 1*-61 because there are parenthesis, which equals -61.

Then, you do -61, which is the total of everything in parenthesis, and do it times the power of 3 to get -226,981.

Hope it helps!!^_^
