Answer: C. 150 km²

<u>Step-by-step explanation:</u>

Use similar triangle proportion to find x:

$\dfrac{x}{4.5}=\dfrac{15.3+7.4}{7.4}\\\\\\x=\dfrac{4.5(22.7)}{7.4}\\\\\\x=13.8\\\\\text{Notice that x is the diameter of the circle}\implies r=\dfrac{13.8}{2}=6.9\\\\\\\text{Find the area of the circle using }A=\pi r^2\\A=\pi (6.9)^2\\\\.\ =\pi (47.6)\\\\.\ =149.6\\\\.\ \approx150$

owen and rose each thought of a linear function. Owen's function is y = 3 4 x + 1, and rose's function is shown in the graph. Wh

slega [8]

Answer:

D) Owen’s function has a greater slope, and Rose’s function has a greater y-intercept

Step-by-step explanation:

slope-intercept form of linear equation: y = mx + b

(where m is the slope and b is the y-intercept)

Slope = change in y ÷ change in x

y-intercept is where the line crosses the y-axis

Owen: y = (3/4)x + 1

Rose: y = (2/3)x + 2

Owen's function has a greater slope, since 3/4 > 2/3

Rose's function has a greater y-intercept, since 2 > 1

Help me understand this better pls

The coordinates of point L are (12, 0).

Step-by-step explanation:

Step 1:

In order to determine the scale factor, we divide the measurement after scaling by the same measurement before scaling.

K is the point before scaling and L is the point after scaling. K and L lie on the same line.

N is the point before scaling and M is the point after scaling. They both lie on the same line.

Step 2:

The scale factor for M $= \frac{-12}{-4} = 3.$

So to determine the coordinates of point L, we multiply point K's coordinates with the scale factor.

Coordinates of point L $= 3 (3, 0) = (3(3), 3(0)) = (12,0).$

So the coordinates of point L are (12, 0).
