Answer:

D. Infinite number

Step-by-step explanation:

A circular plate can be rotated by a part of a degree and it will look the same (as long as it does not have a design on it)

Assuming this plate does not have a design on it, we can rotate through infinite number of lines of symmetry

What is the range of ƒ(x) = |x|?<br><br> (–∞, 0)<br> (–∞, ∞)<br> (0, ∞)<br> [0, ∞)

larisa86 [58]

The range of the function f(x) = |x| is [0,∞)

<h3>How to determine the range?</h3>

The function is given as:

f(x) = |x|

The above is the parent equation of an absolute value function.

The above function cannot output any negative value.

This means that:

ƒ(x) >= 0

As an interval notation, we have:

[0,∞)

Hence, the range of the function f(x) = |x| is [0,∞)

Answer:

$9450

Step-by-step explanation:

We will use compound interest formula:

$F=P(1+r)^t$

Where

F is future amount [what we want to figure out]

P is present amount [9000]

r is rate of interest [since we want for 6 months, the annual interest divided by 2 is r. So r = 10/2 = 5% or 0.05]

t is the time [ the time period is for 6 months so t = 1 since we already converted the interest rate to 6 month chunk]

Putting in formula, we get:

$F=P(1+r)^t\\F=9000(1+0.05)^1\\F=9000(1.05)\\F=9450$
