Does (-1, 2), (1, 1),( 1 -1), (2,1), (4,2) represent y as a function

No. A function maps one input to exactly one output. The given relation maps 1 to both 1 and -1, as indicated by the pairs (1, 1) and (1, -1).

There *must* be an easier way of simplifying this expression. What could I have done differently?

You can add the exponents of x^3*x^4 instead of writing it all out. Do you would just have to add 3+4 since the variable (x) is the same. And you would get x^7

Conner had 354$ and spent 243 cents. How much did conner have left and how many dollars? please help. If you do, then I will tel

Conner: $354 - 243 cents

243 cents = $2.43 because 100 cents = 1 dollar

Conner: $354 - $2.43 = $351.57

$351.57

He has 351 dollars left.

kathryn bought an aquarium to replace her fishbowl.The directions for the aquarium say that it should be filled with 9 cubic fee

lesya [120]

The water should fill the aquarium to 1.5 feet

Solution:

Given that the directions for the aquarium say that it should be filled with 9 cubic feet of water.

This means volume of aquarium is 9 cubic feet

Given that aquarium is 2 feet wide and 3 feet long

To find: Height of aquarium

Since a aquarium is in shape of cuboid, we can use the volume of cuboid formula

The volume of cuboid is given as:

volume of cuboid = $l \times w \times h$

Where "l" is the length

w is the width

"h" is the height

Substituting the values, we get,

$9 = 3 \times 2 \times h\\\\9 = 6 \times h\\\\h = \frac{9}{6} = 1.5$

Thus the height of aquarium is 1.5 feet

a cone has a diameter of 3 inches. The come holds 12 cubic inches of water. To the nearest inch, what is the height of the cone?

Shkiper50 [21]

Volume for a cone is 1/3 pi * r^2*h, where r is radius and h is height. We have diameter = 1/2 radius. Thus, radius = 1.5in. We also have volume is 12 in. Using formula for volume of a cone and plugging in what we know, we have 12 = 1/3*pi*(1.5)^2*h, were solving for h. To get, h= (12*3)/(pi*(1.5)^2), which is approximately 5.0931in, 5 inches
