Which of the following functions is graphed below?

astraxan [27]

Answer: A

Step-by-step explanation:

Take the point (0, -6). The floor of 0 is 0, so normally it would be (0, 0). However, since the y coordinate is -6, not 0, we know it was translated down 6 units. Therefore, the answer is A.

Find the area of the figure. Round your answer to the nearest tenth.

Ulleksa [173]

Answer:

Area of the parallelogram= $10\sqrt{3} m^2$

Step-by-step explanation:

Area of a parallelogram = Length * Perpendicular height

To find the perpendicular height of the parallelogram:

Using given angle 60° in the triangle.

$sin(60)=\frac{Perpendicular}{Hypotenuse}$

$\frac{\sqrt{3} }{2}=\frac{Perpendicular}{4} \\\\Perpendicular=\frac{4\sqrt{3} }{2} \\\\Perpendicular=2\sqrt{3} m$

Area of the Parallelogram:

$=5*2\sqrt{3}\\\\ =10\sqrt{3}$

Area of the parallelogram= $10\sqrt{3} m^2$

Write, in slope intercept form, the equation of the line that passes through (8, -9) and has a slope of -5/4.

dezoksy [38]

Answer:

The equation in the slope-intercept form will be:

$y=-\frac{5}{4}x+1$

Step-by-step explanation:

Given

slope = m = -5/4

point = (8, -9)

As we know that the equation of a line in point-slope form is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -5/4 and point = (8, -9)

$y-\left(-9\right)=\frac{-5}{4}\left(x-8\right)$

$y+9=\frac{-5}{4}\left(x-8\right)$

Writing the equation in slope-intercept form

$y=mx+b$

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

$y+9=\frac{-5}{4}\left(x-8\right)$

subtract 9 from both sides

$y+9-9=\frac{-5}{4}\left(x-8\right)-9$

$y=-\frac{5}{4}x+1$

Therefore, the equation in the slope-intercept form will be:

$y=-\frac{5}{4}x+1$

Least to greatest again? I can't visualize this one.. -11/5, -2.4, 1.6, 15/10, -2.25 Thanks

Tcecarenko [31]

Answer:

Hey again! Just remember about the number lines. If it's easier, you can use a calculator to divide the fractions to make them easier to visualize in decimal form.

The answer to this one is:

-2.4

-2.25

-11/5 (which is -2.2)

-15/10 (1.5)

-1.6
