The lines are not coincident, they do are not, essentially, touching at all points. coincident lines overlap each other, appearing like one line.
Answer:
56 cupcakes
Step-by-step explanation:
First, I convert 3/5 to a percent because I prefer to work with percents:
3/5 = 0.6 = 60%
Then, subtract 60% from 100% for the percent of the total cupcakes that JoJo needs to make:
100 - 60 = 40%
Finally, multiply the total cupcakes by the percent as a decimal:
140 × 0.4 = 56
Answer:
1. 1/2 +/-√5
2. 1 +/- i √6/2.
Step-by-step explanation:
1. f(x) = 4x^2 - 8x - 1
x = [-(-8) +/-√((-8)^2 - 4*4*-1)] / (2*4)
x =[ 8 +/- √80] / 8
= 1 +/- 4√5/8
= 1 +/- √5/2
= 1/2 +/-√5
2. By a similar method the zeros of the the second equation are:
x = [-(-4) +/- √((-4)^2 - 4*2*5)] / 4
= 4 +/- √(16 - 40) / 4
= 1 +/- √(-24)/4
= 1 +/- i √6 * 2 / 4
= 1 +/- i √6/2.
Answer:
Step-by-step explanation:
circumference = 2* pi * radius = 1
-> radius = 0.1592 mile
-
> diameter = 2* radius = 0.31847 mile
