11.8 to a mixed number is 11 8/10 or 11 4/5.
Answer:
Step-by-step explanation:
It is a matter of just substituting the values into the given equation.
4m^2-2n+5
If m=5 and n=9 then it becomes
4(5^2)-2(9)+5
4(25)-18+5
100-18+5
87
Y = mx + b
m = 1
b = 3
y = x+3
Hope it helps :)
The angle is in the second quadrant so only the sine is positive .
Length of the hypotenuse = sqrt (-1^2 + 3^2) = sqrt10
sine = 1/sqrt10 = 0.3162 to 4 dec places
tangent = 1 / -3 = -0.3333 to 4 d p's
cosine = -3/sqrt10 = -0.9487 to 4 d, p's.
