The sides of a square are 3 2/7 inches long.<br> What is the area of the square?

vredina [299]

Area is just height times width so if it’s a square all sides are equal so you do 3 2/7 time 3 2/7 and get 10.796 in^2

Find the constant of variation (k) where y varies directly with x. y = 2, when<br> X = 6.

ExtremeBDS [4]

Answer:

The graph below models the value of a $20,000 car t years after it was purchased.

Value of Car

A graph titled Value of Car has years on the x-axis and Dollars on the y-axis. A line curves down and goes through points (0, 20,000), (4, 10,000), and (14, 2,000).

Which statement best describes why the value of the car is a function of the number of years since it was purchased?

Each car value, y, is associated with exactly one time, t.

Each time, t, is associated with exactly one car value, y.

The rate at which the car decreases in value is not constant.

There is no time, t, at which the value of the car is 0.

Answer:

Using the point-slope form:

The equation of the line is given by:

$y-y_1 =m(x-x_1)$ .....[1] where

m is the slope of the line and $(x_1, y_1)$ is the point on the line.

As per the statement:

Given: Two points i,e (34, 76) and (42, 91)

First calculate slope(m):

Slope is given by:

$\text{Slope} = \frac{y_2-y_1}{x_2-x_1}$

Substitute the given values we have;

$\text{Slope (m)} = \frac{91-76}{42-34}=\frac{15}{8}=1.875$

Now, substitute the value of m and (34, 76) in [1] we have;

$y-76 =1.875(x-34)$

Using distributive property: $a \cdot (b+c) = a\cdot b+ a\cdot c$

$y-76 =1.875x-63.75$

Add 76 to both sides we get;

$y=1.875x+76$

Therefore, the equation of the trend line is: $y=1.875x+76$
