Here, y is a cubic function of x.
When x = 3,



Hence, when x = 3, y = 126.
To start, we can factor the "3" in the parentheses - then move the -4 over. So,
y - 4 = 3x - 3
y = 3x + 1
So the y-intercept of the equation is "1", and the slope is 3.
Answer:
A
Step-by-step explanation:
Answer: c
Step-by-step explanation:
Answer:
It's choice 2. c = 3 sin 45 / sin 40.
Step by-step explanation:
m< A = 180 - 45-95
= 180 - 140
= 40 degrees.
So by the Sine Rule:
c / sin 45 = 3 / sin A
Cross multiply:
c sin A = 3 sin 45
c = 3 sin 45 / sin 40.
