Answer:

a. domain: {0, 2, 4}, range: {2, 6, 10}

Step-by-step explanation:

The given diagram depicts a function.

Let us define function:

A function is a mapping of inputs to output.

The left ones are the input of the function while the right side values are the output of the function.

The domain of the function is the set of values that are given as input to the function while the outputs are called range.

so, in the given question

The domain is: {0,2,4} and the range is: {2,6,10}

So, Option A is correct ..

Find the measure of Q, the smallest angle in the triangle whose sides have lengths 4-5, and 6. Round the measure to the nearest

kakasveta [241]

<u>Given</u>:

Given that PQR is a triangle.

The measures of the sides of the triangle are 4,5 and 6.

We need to determine the measure of ∠Q.

<u>Measure of ∠Q:</u>

The measure of ∠Q can be determined using the law of cosines formula.

Thus, we have;

$\cos (Q)=\frac{p^{2}+r^{2}-q^{2}}{2 p r}$

Substituting p = 6, q = 4, r = 5, we get;

$\cos (Q)=\frac{6^{2}+5^{2}-4^{2}}{2 (6)(5)}$

Simplifying, we get;

$\cos (Q)=\frac{36+25-16}{2 (30)}$

$\cos (Q)=\frac{45}{60}$

Dividing, we get;

$\cos (Q)=0.75$

$Q=cos^{-1}(0.75)$

$Q=41^{\circ}$

Thus, the measure of ∠Q is 41°

Hence, Option b is the correct answer.

The length of a rectangle is 15 and its width is w.

Fed [463]

A rectangle with sides 15 and w has perimeter

$2p = 2(15+w) = 2w+30$

We want this quantity to be at most 50, so it must be less than or equal to 50:

$2w+30\leq 50$

For the record, this implies that

$2w\leq 20 \iff w \leq 10$

So, the width can be at most 10.
