Answer:
Equation of tangent to the line will be 
Step-by-step explanation:
We have given equation 
We have to find the equation of tangent passing through the point (0,8)
Slope of the line will be equal to 
At point (0,8) slope will be 
Equation of line is given by
, here m is slope of the line which is equal to 6 here
So equation of line passing through (0,8)
So equation of tangent to the line will be
Answer:
60
Step-by-step explanation:
Answer:
Z = 90 degrees
Step-by-step explanation:
Reason is a diameter subtends angle of 90 degrees on the circumference
Make sure you know the formula pertaining to the question.
1. c=2(pi)(r)
2. c=2(pi)(d)
r= radius
d= diameter
c= sircumference
So we are given that the circumference of a circle is 12.3pi and the radius is unknown.
So let's plug in the known values
**we use the formula with the radius, becuase we are looking for the radius.
c=2(pi)(r)
12.3(pi)=2(pi)(r)
divide each side by pi
12.3=2(r)
divide each side by 2
r=6.15 in.
Answer:
first one is 42/7 = 6
11*6 = 66
second one
1/2 inch = 3/2 feet
17/2 inches = 17*3 = 51/2 = 25.5
