well, I'd say never, since intersection by its definition means, <u>it comes from somewheres, hits the other, and keeps on going</u>, like the planes P and Q in the picture below.
so intersection by definition is not in a straight line.
Answer:
0.7
Step-by-step explanation:
2,3,4,6,8,9,10 are the possible choices.
∴P(even no. or multiple of 3)
= 7/10
After 3.2 or 3 hours and 12 minutes, the total cost of services is equal.
Explanation:
First, set up equations for total cost for both Happy Paws and Woof Watchers.
x= number of hours
y= total cost
Happy Paws
y= 1.5x + 19
Woof Watchers
y= 2.75x + 15
Because you have to find when the total cost is equal, then the y's of both equations are equal to each other. That means you can substitute the Woof Watchers' 2.75x + 15 into the y of Happy Paws.
2.75x + 15 = 1.5x + 19
Rearrange the equation so the variable, x, is on one side and the numbers on the other and solve.
1.25x = 4
x= 3.2
You can check the answer by plugging 3.2 into x in the two equations and see if they yield the same total cost.
Happy Paws: 1.5(3.2) + 19 = 23.8
Woof Watchers: 2.75(3.2) + 15 = 23.8
Answer:
No ,its irrational
Step-by-step explanation:
bcoz of it is not fixed number
it is infinite number
Answer:
≈ 23 years
Step-by-step explanation:
Initial price= $995
Value increase= 3.1%
a) $995 +3.1%= $995*1.031= $1025.85
b) $995*1.031^x= $2000
1.031^x= 2000/995
1.031^x= 2.01
x= log 2/log 1.031= 22.7 ≈ 23 years
