Answer:
<u>Circumference</u> shares the same concept with perimeter.
First, let's use the formula for the circumference of a <u>full</u> circle.
C = 2πr
Where 'π' stands for pi(22/7 or 3.14) and 'r' stands for the radius.
or
C = πd
Where 'π' represents pi(22/7 or 3.14) and 'd' stands for the diameter.
But, we are trying to find a <u>semi-</u>circle's circumference. So, what you would do is that you would divide the whole product of the formula by 2.
For this, I'll be using this formula C = πd. Though, since we are dividing by 2 we can apply that to the diameter and make it a radius in our formula.
So the 'd' in the formula will be 'r'.
Now, let's find the radius.
D/2 = R
So,
35/2 = 17.5
Use this in our formula:-
C = πr
C = 3.14(17.5)
C = <u>54.95</u> inches.
First let’s put 5x+2y = 12 into slope-intercept form.
2y = -5x + 12
y = (-5/2)x + 6
So any line that is parallel to y = (-5/2)x + 6 must have a slope of -5/2.
Our answer then is y = (-5/2)x + c
Now all that remains is to find out the value of c.
We know this line passes through the point (-2,4). Which means when x = -2, y = 4.
4 = (-5/2)(-2) + c
4 = 5+c
c = -1
Hence the line you want is y = (-5/2)x - 1
Since the question gave the line in standard form and didn’t ask for any particular form, let’s give the answer in the same form that the question asked.
2y = -5x - 2
5x + 2y = -2
Answer:
d. 15-(-18)
Step-by-step explanation:
Take the second point and subtract the first point
15 - (-18)
15 + 18
