Answer:
-1/16

Explanation:
First, when we have a negative power in the numerator, the number with this power will be moved to the denominator and the power is converted to a positive one.
In other words: a^-x = 1 / a^x

In the question, we have:
-(4)^-2
This can be written as:
- 1 / 4^2 = -1 / (4*4) = -1/16

Hope this helps :)

- (4) ^ - 2
 By properties of exponents we have:
 - (1 / (4) ^ 2)
 Rewriting the expression:
 - (1 / (4 * 4))
 - (1 / (16))
 Answer: 
 simplified form of the expression - (4) ^ - 2 is:
 -1/16

Amanda, Bruno and Carla collected bottle caps for charity. Amanda collected (4f – 3) bottle caps. Bruno collects twice as many b
topjm [15]

Answer:

18f - 6 bottles

Step-by-step explanation:

Amanda, Bruno and Carla collected bottle caps for charity. Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda. Carla collects 3(5 + 2f) bottles. How many bottles did they collect altogether in terms of f ?

From the question

Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda.

= 2(4f - 3)

= 8f - 6 bottle caps

Carla collects 3(5 + 2f) bottles.

= 15 + 6f bottles

The number of bottles they collected altogether in terms of f is calculated as:

(4f – 3) bottle + 8f - 6 bottle + 15 + 6f bottle

4f - 3 + 8f - 6 + 15 + 6f

= 18f - 6

Four is a zero of the equation x^3+3x^2-18x-40=0.
Ahat [919]

If 4 is a root, then a factor must be x - 4.

Only choices A and D have x - 4 as a factor.

Now look at the constant term of each binomial in the factorizations of choices A and D.

A.: -4, 4, 5

Their product is -80.

The constant term of the original polynomial is -40, so this factorization cannot be correct.

D.: -4, 2, 5

Their product is -40.

This is the correct factorization.

Answer: D.

Three 5 pound bags= 15

1 pound=16 ounces.

16x15=240

240 divided by 10=24

The answer is 24 bags of 10-ounces.
