Answer:

The volume of a cone is given by the equation:

$V=\frac{1}{3}\pi r^2 h$

where

r is the radius of the cone

h is its height

We have several examples of cones in real life: for instance, the cone of an ice-cream, it has a conic shape.

The volume of a prism instead is given by:

$V=lwh$

where:

l is the length of the base

w is the width of the base

h is the height of the prism

Again, we have several examples of prisms in daily life: for example, boxes have usually the form of a prism, so it can be useful to know their size in order to calculate their volume.

Ashley has a balance of $4,000 on her credit card with an annual interest rate of 13%. To pay off the $4,000 in three years, Ash

Bond [772]

Answer:

Ashley would have to pay an additional $608.52 in interest when the length of the loan changes from 3 years to 5 years.

Step-by-step explanation:

Although the problem gives us the initial amount of the balance ($4000) and the interest rate (13%), we are really only concerned with the total amount Ashley will make in payments in three years versus five years. If she pays $134.78 for three years, that is 36 months, or $134.78 times 36 which is equal to $4852.08. However, if she decides to take longer to pay it and instead pays $91.01 for five years, or 60 months, then her total amount paid would be $5460.60. To find the difference between these two, simply subtract $5460.60-$4852.08 to get $608.52.

Which equation is not a linear equation?

Bond [772]

Answer:

2/x + 3/y = 5

Step-by-step explanation:

A linear equation refers to any equation that can be written in the form;

ax+b=0 or y - mx -c = 0

The graph of a linear equation will always be a straight line; Vertical, horizontal or with a given degree of steepness (slope).

All the equations given are linear, except the last equation;

2/x + 3/y = 5. The exponents of the variables x and y is not 1 hence the equation is non-linear. Find the graph attached;

Write an equation in point – slope form from the line through the given point with the given slope. (-10, -1); m=-1

Alexxandr [17]

Answer:

y = -x - 11

Step-by-step explanation:

We know the equation must be: y = -x + c

However we do not know what "C" is. If we plug in our x and y values then we can find out the value of C.

So:

-1 = -(-10) + c

-1 = 10 + c

so c = -11

So our equation is:

y = -x - 11
