Answer:

The answer to 9 is table A

Step-by-step explanation:

The table has the value of x as -4 in two different spots, therefore it would fail the vertical line test. You could change one of the two values with -4 to anything but -4

PLZ HELP MARKIN BRAINIEST!!!
Dahasolnce [82]

From the graph, when x = 1, y = 57,000.

Replace x with 1 in the equations and see if any of the Y 's equal 57,000 :

y = -2610.82(1) + 47860.82 = 45,250

y = 219(1)^2 - 6,506.78(1) + 59,385 = 219 - 6506.78 + 59385 = 53,097.22

y = 54041.5(0.9)^1 =  48,637.35

y = 10,504.6 (1.1)^1 = 11,555.06

The second equation is the closest. so try another x value to see if it is close to the Y value:

Let's try x = 14:

y = 219(14)^2 - 6506.78(14) + 59,385 = 42924 - 91094.92 + 59385 = 11,214.08

This is close to Y = 12,00 shown on the graph

SO the closest equitation is y = 219x^2 - 6506.78x + 59385

Given that circumference of a circle is 44m. Calculate it's area​
dimaraw [331]

Answer:

Area=154.062 m^{2}

Step-by-step explanation:

As Circumference of a circle is given by;

C=2\times \pi\times r

As the circumference is 44m so we can calculate the value of r by using the above formula.

44=2\times \pi \times r\\\\\frac{44}{2\pi} =r\\\\\implies r=\frac{22}{\pi} =7.003 m

Now to Calculate the Area of a Circle.

As the area of a circle is,

Area =\pi \times r^{2}\\ Area=\pi \times (7.003)^{2} \\Area=\pi \times 49.039\\Area=154.062m^{2}
