Answer:
35 combinations
Step-by-step explanation:
You have to use the formula for finding combinations in probability. It looks like this:
₇C₃ = 
so that gives you
₇C₃ = 
The 4 factorials cancel each other out, and when you do the math, you get 210/6. That divides evenly into 35. So there are 35 combinations.
The answer is CD = √3
This is because of the fact that a 30-60-90 right triangle has proportions of 1-√3-2 based on the length opposite of the angle. Since we are given the segment opposite to the right angle as 2, we know that we can use the base numbers for the proportions to find the rest. Since CD is opposite of the 60 degree angle, it must be √3.
Answer:
1) Clare's stone hit first.
2) 1 seconds.
3) Same maximum height for both.
4) 9 feet
Part A:
h = (-16t -8)(t - 1)
When the stone hits the water, the height will be 0
⇒ (-16t - 8)(t - 1) = 0
<u>set to zero</u>
⇒ -16t - 8 = 0, t - 1 = 0
<u>simplify</u>
⇒ t = -1/2, t = 1
So, time was 1 seconds for Clare and 1.25 seconds or Lin. Clare's hit first.
Part B:
For Lin's stone: maximum height: 9 feet.
For Clare stone: (-16(0.25) - 8)((0.25) - 1) = 9 feet
No both stone reached the maximum height of 9 feet.
Answer:
-28
Step-by-step explanation:
2(x-5) = 3(x+6)
Solve for x by first distributing
2x-10=3x+18
Subtract 2x to both side to get x by itself
-10 = x +18
<em> x = -28</em>
