Answer:
141; 6526; 28d.
Step-by-step explanation:
try this option, all the details are in the attachment.
Diameter is 2.36 cm.
Given:
Circumference = 7.38 cm
Circumference of a circle is computed by multiplying 2, pi, and its radius.
C = 2πr
7.38 = 2 (3.14) r
7.38 = 6.28r
7.38/6.28 = 6.28r/6.28
1.18 = radius
Diameter = 2r
Diameter = 2(1.18)
Diameter = 2.36 cm
That's point-slope form:
y - y1 = m(x - x1)
Where y1 is the y-value of a point on the line, x1 is the x-value, and 'm' is the slope.
So let's find out what goes in the first blank.
As we can see, they replaced 'x1' with -1, and one of our points have an x-value of -1, that point is (-1, -2), this means y2 must be -2:
y + 2 = m(x + 1)
Now let's find the slope between the two points.
m = y2-y1/x2-x1
m = (10+2)/(3+1)
m = 12/4
m = 3
So the slope is 3, plug that in:
y + 2 = 3(x + 1)
