Answer:

Option C.

Step-by-step explanation:

A dashed straight line has a negative slope and goes through (0, 2) and (4, 0).

The given inequality is

$y$

We need find the point which is a solution to the given linear inequality.

Check the given inequality for point (2, 3).

$3$

This statement is false. Option 1 is incorrect.

Check the given inequality for point (2, 1).

$1$

This statement is false. Option 2 is incorrect.

Check the given inequality for point (3, -2).

$-2$

This statement is false. Option 3 is correct.

Check the given inequality for point (-1,3).

$3$

This statement is false. Option 4 is incorrect.

Therefore, the correct option is C.

svetlana [45]

There are 60 minutes in an hour and percent means per one hundred so:

p/100=18/60

p=1800/60

p=30%

Describe, in general, the steps for producing a frieze pattern.

Delvig [45]

An infinite strip with a symmetric pattern is called a frieze pattern.

There are only seven possible frieze pattern.

1. Translation symmetry only.

2. Glide reflection plus translation symmetry.

3. Reflection over a horizontal line plus translation.

4. Reflection over a vertical line plus translation.

5. Rotation (a half-turn about a point on the mid line of the strip) plus translation.

6. Reflection over a vertical line plus a reflection over a horizontal line plus translation.

7. Reflection over a vertical line plus glide reflection plus translation.

Find the range of the following piecewise function.

Anna11 [10]

Given:

The piecewise function is

$f(x)=\begin{cases}x+4 & \text{ if } -4\leq x$

To find:

The range of given piecewise function.

Solution:

Range is the set of output values.

Both functions $f(x)=x+4$ and $f(x)=2x-1$ as linear functions.

Starting value of $f(x)=x+4$ is at x=-4 and end value is at x=3.

Starting value: $f(-4)=-4+4=0$

End value: $f(3)=3+4=7$

Starting value of $f(x)=2x-1$ is at x=3 and end value is at x=6.

Starting value: $f(3)=2(3)-1=5$

End value: $f(6)=2(6)-1=11$

Least range value is 0 at x=-4 and 0 is included in the range because -4 is included in the domain.

Largest range value is 11 at x=6 and 11 is not included in the range because 6 is not included in the domain.

So, the range of the given piecewise function is [0,11).

Therefore, the correct option is A.

What is the value of the expression 2^0/4^2

xz_007 [3.2K]

Anything to the zeroth power is equal to 1. (The numerator is equal to one because of this rule)

So.

$\frac{1}{4^2} = \frac{1}{16}$
