5. Linear

In a linear function, the rate of change is constant.

A linear function is also of the first degree.

Item 1:

From -3 to -1, the rate of change is of

From -1 to 1, the rate of change is of .

Different rates of change, so non-linear.

Item 2:

At function b, from 0 to 1, the rate of change is of 1, from 1 to 2 of 3, different rates of change, so non-linear.

Item 3:

Highest degree of x is 1, so first degree, and thus linear.

Item 4:

The only non-linear is , which is of the second degree.

is a constant function, with a rate of change of 0, so linear.

The last function is written as:

Highest degree of x is 1, so also linear.

Item 5:

In all cases, the rate of change is constant, so linear

Find the value of x. Round your answer to the nearest tenth. Will mark brainlist !

mars1129 [50]

Answer:

answer is 17.5

Step-by-step explanation:

use formula a^2 + b^2 = c^2 (letters represent each side of the triangle)

9^2 + 15^2 = 306

306 = x^2. find the square root of 306 to find x

√306 = 17.4928557

rounded it to the nearest 10th

Find the arc length on a circle with radius =4 inches and central angle of 30°

Elenna [48]

Answer:

Step-by-step explanation:

I'm assuming you're not doing the pre-calculus version of this equation where your angle is in radians. So we'll do the Geometry version which looks like this:

$AL=\frac{\theta}{360}*2\pi r$

Our angle is 30 and our radius is 4, so we fill in accordingly:

$AL=\frac{30}{360}*2(3.1415)(4)$ (this is if you multiply in pi. We'll find the answer in terms of pi as well).

AL = $\frac{1}{12}*25.132$ and

AL = 2.09433 inches

In terms of pi, the answer would be

AL = $\frac{2}{3}\pi$ inches
