The line in red
Coordinate points (1, 1) and (0, -1)
slope m = (1 + 1)/(1 - 0) = 2
b = y intercept = -1
so equation in slope intercept form: y = mx + b
in this red line y = 2x - 1
Answer
Red: y = 2x - 1
I don’t see anything love, please redo them I will answer :p
<u>ANSWER:
</u>
The engine have 5.39 qt approximately.
<u>SOLUTION:
</u>
Given, a specific cars engine has a capacity of 5.1 L of oil.
We need to find how many quarts of oil does the engine have?
Number of quarts of oil is product of number of liters of oil and the number of quarts per liter.
We know that, one liter of liquid contains 1.056 quarts approximately.
Number of quarts of oil = number of liters of oil x number of quarts per liter.
Number of quarts of oil = 5.1 liters x 1.056 quarts.
Number of quarts of oil = 5.1 x 1.056
Number of quarts of oil = 5.389 qt.
Hence, the engine have 5.39 qt approximately
Prob(a head on 1 toss) = 1/2
So probability of 8 heads in a row = (1/2)^8 = 1/256 or close to 0.391%
#3 sin(x) = -sqrt(2)/2 so x = 315 degrees. So we have sin(x+pi/3) = sin(375) = sin(15) which in exact form would be (sqrt(3) -1)/(2sqrt(2))
#4 to find x we take the arctan(20/21) which is approximately 43.6 degrees and add 180 to it since it's in the 3rd quadrant which is 223.6 degrees so we do sin(223.6 + 90) = sin(313.6) which equals -21/29. This can also be done with the pythagorean theorem. -21/29.
#5 13^2 - 5^2 = 12^2. so sin is -12/-13 = 12/13. we take arcsin of that and add 180 and then divide by 2 and take the sin of that and its approximately 3/sqrt(13).
#6 sin is 4/5 so we take arcsin of that and get 143.13 which -60 is 83.13 and we take the sin of that to get 3/10 + 2sqrt(3)/5
Hope this helped :L
