f(2.5) means x is equal to 2.5.
Replace x in the equation with 2.5 and solve:
6(2.5) + 1.5 = 15 + 1.5 = 16.5
f(2.5) = 16.5
Answer:
given the sun has risen every day for the last 5000 years — or 1,826,213 days — the probability it will rise tomorrow is 1,826,214 / 1,826,215. which is 99.9%
Answer:
y = 2x/3 + 1
Step-by-step explanation:
<span>y = 3x - 7
3 = slope
-7 = y intercept
This line would cross the y intercept at -7, and go up by 3 (slope). </span>
Answer:
Sin x = a / b.
Step-by-step explanation:
The opposite side =a and the adjacent side = 4 (because tan x = a/4.
Cos x = 4/b so the hypotenuse = b ( because Cos = adjacent /hypotenuse.
So sin x = opposite /hypotenuse = a / b.
