Step-by-step explanation:

We can set up the ration of the radian angle θ in your problem in terms of degrees given as the ratio: (Θ/2·pi) = (72/360), solving for Θ we get Θ = 1.26 radians. Then for the arc length s = Θ·r using this value gives s = 1.26·4 = 5.04

Does the equation represent a linear or nonlinear function? Explain.<br><br> y = x + 5

mrs_skeptik [129]

Answer:

Below.

Step-by-step explanation:

A linear function contains a variable of the first degree only - for example f(x) = 2x - 1 or f(z) = 3z.

So y = x + 5 is linear.

Willa says the slope of the graph is -1/3.What error did she make?

Nataly [62]

ANSWER

She counted the squares instead of using the scale.

EXPLANATION

The slope of a line is calculated using the formula

$m = \frac{rise}{run}$

This is the same as:

$m = \frac{y_2-y_1}{x_2-x_1}$

The given straight line passes through:

(4,24) and (16,18).

We plug in the values to obtain,

$m = \frac{18 - 24}{16 - 4}$

$m = \frac{ - 6}{12}$

$m = - \frac{ 1}{2}$

This is the correct expression for the slope.

But Willa mistakenly counted the squares instead of using the scale and had

$m = - \frac{1}{3}$

Each box on the y-axis is 3 units and each box on the x-axis is 2 units.

The rise is one box along the y-axis which is equal to 3 units the run is 3 boxes which is equal to 6 units.

The line has a negative slope.

Because she just counted the boxes and did use the scale, she got a wrong answer.

Algebra 2 help please ASAP

Burka [1]

Answer:

The option A,D and E are correct.

Step-by-step explanation:

Given: 2x^3-250x^2

Factor : 2x^2(x-125)

So, GCF = 2x^2

Now a = 1 and b= 5

we know that a^3-b^3 = (a-b)(a^2+ab+b^2)

(x)^3 - (5)^3 = (x-5)(x^2+5x+25)

So, the option A,D and E are correct.
