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
Answer:
4 answer
Step-by-step explanation:
The volume of the given figure is 104 m³.
We need to find the volume of the given figure.
<h3>What is volume?</h3>
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
Divide the given figure into two convenient cuboids. That is one with dimensions length=4 m, breadth=4 m and height=3 m. Another with length=4 m, breadth=7 m and height=2 m.
We know that, the volume of cuboid =l×b×h cubic units.
Now, the volume of cuboid=4×4×3=48 m³ and the volume of another
cuboid=4×7×2=56 m³.
The volume of the given figure=48+56=104 m³.
Therefore, the volume of the given figure is 104 m³.

200 and 150 because 25% of 200 is 50 so subtract 50 from 200 because it is supposed to be 25% smaller
Answer:
10
Step-by-step explanation:
so what we have to do is plug the values in
6y/x
so x=3 and y=5
so we just have to plug the values in correspondingly
6(5)/3
30/3
