<h2>As the graph shows the cost of apples at a local market, Use the graph to answer problems 1-3</h2>

Part 1)

What is the cost of 1 apple and of 3 apples? How do you know?

Answer:

From the given graph which shows the cost of apples at a local market, it is clear that:

When we buy 1 apple, the cost is indicating 0.5+ (0.5/2) = 0.5+0.25 = $0.75

We know because x-axis is representing the number of apples and y-axis is representing the cost.

Therefore, when the number of apples is 1 on x-axis, then the cost is showing $0.75 on y-axis.

also

when we buy 3 apple, the cost is indicating 2+ (0.5/2) = 2+0.25 = $2.25

We know because x-axis is representing the number of apples and y-axis is representing the cost.

Therefore, when the number of apples is 3 on x-axis, then the cost is showing $2.25 on y-axis.

Part 2)

What does the point (0, 0) represent in this context?

The (0, 0) represents the origin of the graph.

It means that the cost will be zero US dollars if you do not buy any apple. In other words, for 0 number of apples, the cost will be $0.

Part 3)

What does the point (2, 1.5) represent in this context?

The (2, 1.5) represents that when you buy 2 apples, the cost for buying 2 apples will be $1.5.

We know because x-axis is representing the number of apples and y-axis is representing the cost.

Therefore, when the number of apples is 2 on x-axis, then the cost is showing $1.5 on y-axis.

A can has a radius of 2 inches and a volume of 62.8 cubic inches. Find the height of the can.

irina [24]

ANSWER
The height of the cylinder is,
$h=5inches$

EXPLANATION

The volume of a cylinder can be found using the formula,

$V = \pi {r}^{2} h$

To make h the subject, we divide through by
$\pi \: {r}^{2}$

This will give us,

$\frac{V}{ \pi \: {r}^{2} } = h$

We now substitute

$V=62.8$
$r = 2$
and

$\pi = 3.14$

into the given expression for h to obtain,

$h = \frac{62.8}{3.14 \times {(2)}^{2} }$

We simplify to get,

$h = \frac{62.8}{12.56}$

$h = 5$

Therefore the height of the cylinder is 5 inches.
