Explain why statement 3^(-2)=-6 is false

1 answer:

malfutka [58]2 years ago

6 0

Answer: -9

Step-by-step explanation: You are not doing 3(-2) to get -6. That's incorrect. What you are supposed to do is multiply the base which is 3 and then multiply it with -2 so that would 3(3) twice and don't forget the negative in front of the two so that would be -9 as the correct answer. :)

Given f(x)=2x^2-3 and g(x) = x+4 What is (fg)(x)?

Ira Lisetskai [31]

Answer: $f(g(x))=2x^2+16x+29$

Step-by-step explanation:

$f(x)=2x^2-3\\g(x)=x+4$

f of g of x means "function f, replace x by the value of g of x"

$f(g(x))=2x^2-3\\f(g(x))=2(x+4)^2-3\\f(g(x))=2(x^2+8x+16)-3\\f(g(x))=2x^2+16x+32-3\\f(g(x))=2x^2+16x+29$

A farmer is able to prepare 1/2 are of soil in 3 days. How long will it take him to prepare 2 1/4 acres of soil?

Alexxx [7]

Answer:

x = 13 1/2 days

Step-by-step explanation:

1/2 acre 2 1/4 acre

------------ = -------------------------

3 days x days

using cross products

1/2 * x = 2 1/4 * 3

change 2 1/4 to an improper fraction (4*2+1)/4 =9/4

1/2 x = 9/4*3

1/2x = 27/4

multiply each side by 2

2 * 1/2 x = 27/4 * 2

x = 27/2

change back to a mixed number

x = 13 1/2
