Step-by-step explanation:
Hi there!
First, complete the square:
Simplify:
I hope this helps!
Step-by-step explanation:
let the angle in 3rd quadrant be X
x+2=180
None 3 * 66 = 198
ALL triangles have a total degree measure of 180 degrees
Answer:
(1) The slope intercept should be y=1/2x-5
So the table should be
x y point
-2 -6 (-2,-6)
0 -5 (0,-5)
2 -4 (2,-4)
(2) The slope -5/4
Step-by-step explanation:
(1) The reason why when she graphed the points is incorrect is because she needs to graph it in point slope form not in standard form and when she used the equation.
To find the slope intercept form you need to get the y on one side by itself:
x-2y=10
Subtract x on both sides:
-2y=-x+10
Divide by -2 on both sides:
y=1/2x-5
(2)The formula for the slope is y2-y1/x2-x1
-2-3/5-1
Which is -5/4
Thus the slope is -5/4

Answer:
c.132
Step-by-step explanation:
so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**
but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**
so we have to divide 42/2 which equals 21
now we need to set up the formula;
c=2πr/c=2xπxr **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**
c=2π21
=131.946891451
and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132
good luck :)
i hope this helps
have a good one !!
