Answer: 180/540
Simplified term would be 1/3
The answer is b
Answer:
43.96 or C
Step-by-step explanation:
c=(pi)(d)
pi --> 3.14
d --> diameter (in your case 14.)
c=3.14*14
c= 43.96
Both formulas work, 2(pi)r and (pi)(d)
But, if they give you the diameter then use (pi)(d).
If they give you the radius then use 2(pi)r
Lets say there are x blue marbles.
Purple marbles = 5 + 3x
Blue marbles = x
Total = 65
5 + 3x + x = 65
5 + 4x = 65
4x = 65 - 5 = 60
x = 60/4 = 15
Blue marbles = 15
65 - 15 = 50
There are 50 purple marbles.
Answer:
Step-by-step explanation:
so to find the equation tangent to the curve x^2+1 at the point (1,2)
-First we must find the derivative then plug in the point
d/d(x)=2x (power rule)
so then we plug in the x and y values (we don't need to worry about the 2-y value- because we did not need to compute and derivatives with y)
so we plug in 1 for the x
y=2(1)
2
now we plug it into equation of a line
y - 2 = 2(x - 1)
or
y=2x
