A. Like charges repel each other. Just think opposites attract for charged particles.
Answer:
ly = 14.75
Step-by-step explanation:
4ly – 51 – 8 = 0
4ly - 59 = 0
combine 59 and 0
4ly = 0 + 59
4ly = 59
divide by 4
4ly/4 = 59/4
ly = 14.75
To figure out this problem break it down into steps.
We know that there are 1 - 25 or 25 cards in total, one card is taken out and not replaced so now there are only 24 cards.
25 - 1 = 24.
Find the probability of getting one number greater than 10, this would be all numbers from 10 - 25, which are 25 - 10 = 15 options to choose that will give you a value greater than 10.
Probability = 15/24 = 5/8.
For 2 cards simply multiply the probability by itself to get 2 cards where the number is greater than 10.
5/8 • 5/8 = 25/64.
The probability of getting 2 cards that are greater than 10, are 25/64.
This is the solution.
Answer:
x = -1/2 ( 3±sqrt(37))
Step-by-step explanation:
x^2 + 3x − 7 = 0
Add 7 to each side
x^2 + 3x =7
Using complete the square
Taking the coefficient of x
3
Divide by 2
3/2
Square it
(3/2)^2 = 9/4
Add this to each side
x^2 + 3x+ 9/4 = 7+9/4
( x+ 3/2) ^2 = 28/4 + 9/4
( x+ 3/2) ^2 = 37/4
Take the square root of each side
x+3/2 = ±sqrt(37/4)
x+3/2 = ±sqrt(37) / sqrt(4)
x+ 3/2 = ±sqrt(37) / 2
Subtract 3/2 from each side
x = -3/2 ±sqrt(37) / 2
x = -1/2 ( 3±sqrt(37))
