Which is the graph of y = _0.4x? A. B. C. D.

1 answer:

8 0

Y = -0.4x

1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °

With all that information you can identify the graph, given that you didn't include the options.

The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 and 5.6 feet. What is the height of the trapezoid

olasank [31]

Answer:

The height is 8.3 feet

Step-by-step explanation:

The area of a trapezoid is calculated using the formula:

Area=½(sum of bases)*height

We substitute area=70.55, and the base lengths 11.4 and 5.6 feet and solve for the height.

$70.55 = \frac{1}{2} (11.4 + 5.6)h$

$70.55 = \frac{1}{2} (17)h$

$70 .55 = 8.5h$

$h = \frac{70.55}{8.5}$

$h = 8.3$

Here is my anser:

We need to find the slope of the of and from the graph, we see that if x increases from 2 to 4, y decreases from 4 to -2. Thus, the slope of the blue line is : $\frac{-2-4}{4-2}$ = -3

But the slope of the perpend. bisector of the blue line is the negative reciprocal of -3, or m= 1/3.

Let's find the slope-intercept form of this bisector. We need to determine b in y=mx+b. Referring to the midpoint of the blue line, x= 3; y= 1; and m=1/3. Then

y=mx+b becomes 1=(1/3)(3) + b. Solving for b: 1=1+b. Then b=0.

Thus, the equation of the perpendicular bisector of the blue line through (3,1) is y=mx + b, or y=(1/3)x + 0, or y=x/3.
