Answer:
37.7
Step-by-step explanation:
<h2><u>circumference of a circle:</u></h2>
Formula = 2πr
r is the radius
diameter = 2* radius
hence radius = 12/2
radius = 6 yards
2*π*6 = 37.6991

<h3><u>circle circumference is 37.7</u></h3>
This is a kite due to the adjacent congruent sides (shown by the tickmarks). With any kite, the diagonals are perpendicular. So angle 3 is 90 degrees.
<h3>Answer: 90 degrees</h3>
X/y (3/-1 just look at where the a is if it is o. ln the x axis or y axis then look to see if it's positive or negative
In this case, the best method starts with finding one percent of the selling price. To do this, divide the commission ($11825) by 5.5. This gets you 1%, which is $2150. Next, multiply this number by 100, turning 1% into 100%. Your final answer is $215,000.
The only non-linear equation from your choices is the area of a circle as it is:
A=πr^2 and if you take the derivative of A you have:
dA/dr=2πr
So the rate of change changes as r changes, it is not constant thus the function has acceleration, so velocity changes.
This is in contrast to any linear equation which is of the form:
y=mx+b now taking the derivative you see that:
dy/dx=m, now m is a constant value, which means that there is no acceleration and the velocity remains constant.
