The power rule applies to each term.
... (d/dt)(t^n) = n·t^(n-1)
... g'(t) = 2t +5
... g'(7) = 2·7 +5 = 19
Y = - 13 + 3x
1) the equation is a striaght line with y-intercept - 13 and slope 3
2) the horizontal axis is x, number of hours.
3) the vertical axis is y, temperature measured in °F
4) y-intercept = - 13=>: point (0, - 13)
5) x - intercept: y = 0 => x = 13/3 => point (13/3 , 0)
With all that information you can draw the graph easily.
Answer:
Step-by-step explanation:
That's a complex expression, let's simplify it, step by step, off the start, we'll simplify the 55/11:
Then we'll simplify the x's and y's:
Let's split the square root in two and solve the bottom part:
The solution is then:
