f(10) = -130
16. Which is greater, 4^-2 or
2^-4? How do you know?
Those are exponents.
Answer:
Both are equal to [tex]\frac{1}{16}[/tex]
Step-by-step explanation:
If the exponent is negative we can turn it into a fraction and make it positive.
This means the number goes to the denominator and the numerator becomes one. Therefore the following.
[tex]4^{-2} = \frac{1}{4^{2} } =\frac{1}{16}[/tex]
[tex]2^{-4} =\frac{1}{2^{4} } = \frac{1}{16}[/tex]

Given the side measurements, classify the triangle as acute, obtuse, right, or not a triangle. 8, 12, 14
Answer: It's an acute triangle.
Step-by-step explanation: I have the same problem, and I tried each choice, acute was the correct answer
The triangle with side lengths 8, 12, 14 is an obtuse triangle.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
To determine whether the triangle is acute, obtuse, or right, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.
8² + 12² = 64 + 144 = 208
14² = 196
Since 208 is greater than 196, we can see that the triangle does not satisfy the Pythagorean theorem. Therefore, the triangle is not a right triangle.
Since the longest side is 14 and the sum of the squares of the two shorter sides is less than the square of the longest side, we can conclude that the triangle is obtuse.
Therefore, the triangle with side lengths 8, 12, 14 is an obtuse triangle.

A rectangular box has a width of x meters, length of x + 3 meters, and
a height of x 2 meters. Write an expression for its volume.
Answer:
x*(x+3)*(x^2)
Step-by-step explanation:
Width: x meters, length: x + 3 meters, height x^2 meters
It's an expression, so there's no simplifying needed.
x(x+3)(x^2)
But if I'm wrong and it's supposed to be simplified, Read the rest.
First, multiply x by x + 3
x(x + 3)
x^2 + 3x
Now, multiply x^2 + 3x by x^2

1/2 ornament in an hour
Step-by-step explanation:
Given

Determine the ornaments per hour
This question implies that we calculate the unit rate.
[tex]Unit\ Rate = \frac{Orna\ ments}{Time}[/tex]
Substitute values for Time and number of ornaments
[tex]Unit\ Rate = \frac{2}{4}[/tex]
[tex]Unit\ Rate = \frac{1}{2}[/tex]

To solve , equate to zero, that is
(2x - 4)² = 0, so
2x - 4 = 0 ( add 4 to both sides )
2x = 4 ( divide both sides by 2 )

What is the original price of the tennis racquet?
A drawing of a tennis racquet with a tag for sale labeled “30 percent off. Now 21 dollars.”
The original price is $
The original price of the racket is $30
Markup and discount priceLet the original price be x
If there is 30% off the original price, then the new price will be 0.7x
If the price of tennis racquet is now $21, hence;
0.7x = 21
Divide both sides by 0.7
0.7x/0.7 = 21/0.7
x = 21/0.7
x = $30
Hence the original price of the racket is $30

Step-by-step explanation:
It's simplest form is when it's fully expanded.
To expand: (3s-4)(4s+5)
(3s * 4s) + (3s * 5) + (-4 * 4s) + (-4 * 5)

= 12s^2 - s - 20
Explain how solving an equation with variables on both sides of the equation is different than solving an equation with a variable on only one side. Please use an example of each to show your work. You may use these examples or make up your own: 6x -9 = 15 16x - 20 = 44+ 5x show your work and explain your steps and why.
Answer:
See explanations below
Step-by-step explanation:
Given the equation
6x-9 = 15
Add 9 to both sides
6x-9+9 = 15+9
6x = 24
x = 24/6
x = 4
For the equation
16x - 20 = 44+ 5x
Since we have x variables on both sides, we will collect the like terms
16x - 5x = 44+20
11x = 64
Divide both sides by 11
11x/11 = 64/11
x = 64/11
x = 5.82
Hence the value of x is 5.82

A light bulb consumes 11700 watt-hours in 3 days and 6 hours. How many watt hours does it consume per day?
Answer:
3600 watt-hours consumed per day.
Step-by-step explanation:
First we'll want to find how many hours are in 3 days and 6 hours.
3 x 24 = 72 + 6 = 78
78 hours is 3 days and 6 hours.
We then divide 11700 by 78 to find out how many watt-hours it will consume per hour.
11700 / 78 = 150
Now that we know how many watt-hours it will consume per hour, we can multiply it by 24 to find out how many it will consume in a day.
150 x 24 = 3600
