A store is selling five cans of tomato sauce for $5.25. What is the unit price?

Svetach [21]

The unit price is tantamount to saying the price of each. For this item, we are asked to determine the price of each can. Thus, it can be determined by dividing the price to number of cans.
$5.25 / 5 = 1.05
Thus, each can of tomato sauce costs $1.05.

If 2y=x³ + 2x², find dy/dx when x=2.

scZoUnD [109]

Answer:

Step-by-step explanation:

$\boxed{\textsf{If }y=x^n,\: \textsf{then }\dfrac{\text{d}y}{\text{d}x}=nx^{n-1}}$

<u>Given equation</u>:

$2y=x^3+2x^2$

Isolate y by dividing both sides by 2:

$\implies y=\dfrac{1}{2}x^3+x^2$

Differentiate with respect to x:

$\implies \dfrac{\text{d}y}{\text{d}x}=3 \cdot \dfrac{1}{2}x^{3-1}+2 \cdot x^{2-1}$

$\implies \dfrac{\text{d}y}{\text{d}x}=\dfrac{3}{2}x^2+2x$

Finally, substitute x = 2 into the differentiated equation:

$\begin{aligned} \implies \dfrac{\text{d}y}{\text{d}x} & =\dfrac{3}{2}(2)^2+2(2)\\\\ & = \dfrac{3}{2}(4)+4\\\\ & = \dfrac{12}{2}+4\\\\ & = 6+4\\\\ & = 10\end{aligned}$

If a person walks 1/6 mile in 10 mintues how far will that person walk in one hour

zvonat [6]

Answer:

1 mile

Step-by-step explanation:

We can write a ratio to solve

We know 1 hour is 60 minutes

1/6 mile x miles

------------ = ---------------

10 minutes 60 minutes

Using cross products

1/6 miles * 60 minutes = 10 minutes * x

10 = 10x

Divide by 10

1 = x

1 mile
