How do you use exponents in a test

Mathematics
1 answer:
katrin2010 [14]3 years ago
7 0

Answer:

An exponent is a number that is to a certain value, like 5^2.

The ^2 means multiply by itself by itself ONCE,

so it would be 5x5.

5^3 means multiply it by itself TWO TIMES,

and going on and on.

Let's say you have a test and the question it's asking is to simplify 5^4.

It's 5x5x5x5, multiplying it by itself FIVE TIMES.

Hope this helped!

an open box is to be made from a piece of metal 16 by 30 inches by cutting out squares of equal size from the corners and bendin
blagie [28]
Let the lengths of the bottom of the box be x and y, and let the length of the squares being cu be z, then
V = xyz . . . (1)
2z + x = 16 => x = 16 - 2z . . . (2)
2z + y = 30 => y = 30 - 2z . . . (3)

Putting (2) and (3) into (1) gives:
V = (16 - 2z)(30 - 2z)z = z(480 - 32z - 60z + 4z^2) = z(480 - 92z + 4z^2) = 480z - 92z^2 + 4z^3
For maximum volume, dV/dz = 0
dV/dz = 480 - 184z + 12z^2 = 0
3z^2 - 46z + 120 = 0
z = 3 1/3 inches

Therefore, for maximum volume, a square of length 3 1/3 (3.33) inches should be cut out from each corner of the cardboard.
The maximum volume is 725 25/27 (725.9) cubic inches.

a circle pizza with a diameter of 10 inches. The pizza is in a square box with side lengths of 14 inches. In square inches, how
julsineya [31]

Answer:

117.45 in^2

Step-by-step explanation:

Given data

Diameter of pizza= 10in

Radius of pizza=10/2=  5in

Lenght of pizza box= 14in

Area of pizza= πr^2

A= 3.142*5^2

A= 3.142*25

A= 78.55 in^2

Area of pizza box= L^2

A= 14^2

A= 196 in^2

Hence the empty space is

=196-78.55

=117.45 in^2
