Answer:

B

Step-by-step explanation:

We have the function:

[tex]f(x)=x^2-5x[/tex]

And we are given that:

[tex]f(n)=-4[/tex]

And we want to find the value of n such that this is true.

So, let's substitute f(x) for -4 and x for n. This yields:

[tex]-4=n^2-5n[/tex]

Let's solve for n. First, add 4 to both sides:

[tex]n^2-5n+4=0[/tex]

This is a quadratic. We can solve by factoring:

[tex](n-1)(n-4)=0[/tex]

Zero Product Property:

[tex]n-1=0\text{ or } n-4=0[/tex]

Solve for n for each equation:

[tex]n=1\text{ or }n=4[/tex]

So, n can be either 1 or 4.

Our of our answer choices, the correct answer is B.

And we're done!

Consider the function f(x) = 10(x2 – 7x). What are the additive and multiplicative inverses?
O The additive inverse is g(x) = 10(x2 + 7x) and the multiplicative inverse is h(x) =
1
10(x2 - 7x)
1
O The additive inverse is g(x) = -10(x2 – 7x) and the multiplicative inverse is h(x)
10(x2 - 7x)
o The additive inverse is g(x) = 10(x2 + 7x) and the multiplicative inverse is h(x) = 1o (x2-7x).
O The additive inverse is g(x) = –10(x2 – 7x) and the multiplicative inverse is h(x) = 10 (x2 - 7x)

To find the height of this tree, Luis marked the tree at eye level, 1.8 meters above the ground. He measured 32 m from the base of the tree and then held a 5-cm ruler vertically in front of his eye until the ruler just obscured the tree above the mark. Using a string tied through a hole in one end of the ruler, Luis found that the distance from his eye to the ruler was 4.7 centimeters. What was the height of the tree? Round to the nearest meter.
