Answer:
Given:
Relation between position of an object at time t is given by:
s(t) = -9 - 3t
To Find:
Instantaneous velocity (v) at t = 8
Step-by-step explanation:
To find instantaneous velocity we will differentiate relation between position of an object at time t by t:
Differentiate the sum term by term and factor out constants:
The derivative of -9 is zero:
Simplify the expression:
The derivative of t is 1:
Simplify the expression:
(As, there is no variable after differentiating the relation between position of an object at time t by t so at time t = 8 is of no use.)
So,
Instantaneous velocity (v) at t = 8 is -3
-/7? imagine that there is an -1 as the numerator. so now -/7 turns into -1/7
The answer is B.
x² + 7x + 10 factors into (x + 2)(x + 5), so x = -2 and x = -5. Since the y-intercepts of the graph are also -2 and -5, you know that the function correlates to that graph.

Answer:
b: 36
Step-by-step explanation:
Since each shovel makes up 50 percent of the profit.
50N=1800
N=1800/50
N=36
