We know that 40$ is a constant and the number of texts sent (t) will change the price therefire we can plug it in the basic linear equation (p being the total price): p= 0.2t + 40

Pipe cost $3 per foot. The equation y = 3x relates the cost of a piece of pipe (y) to the number of feet (X). Identify the unit
JulsSmile [24]

Answer:

The unit rate is 3\frac{\$}{ft}

Step-by-step explanation:

Let

x ----> the number of feet

y ----> represent the cost of a piece of pipe

we have

y=3x

Remember that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have a proportional relationship

The unit rate is the same that the slope of the linear function or the constant of proportionality k

so

m=k=3\frac{\$}{ft}

therefore

The unit rate is 3\frac{\$}{ft}

<h3>Answer:</h3>

sec²(x)

<h3>Explanation:</h3>

As required:

... = (sin²(x)/cos²(x))(1 +(cos²(x)/sin²(x))

... = (sin²(x)·(sin²(x)+cos²(x)) / (cos²(x)·sin²(x))

... = 1/cos²(x) = sec²(x)

_____

Alternatively, multiply out the given expression, then use trig identities.

... = tan²(x) + (tan(x)·cot(x))² = tan²(x) +1 = sec²(x)
