Answer:
v(t) = 6t^2 +5
Step-by-step explanation:
Velocity is the derivative of position. The derivative of a sum is the sum of the derivatives of its terms. The power rule for derivatives is ...
(d/dx)(x^n) = n·x^(n-1)
So, the derivative of d(t) is ...
v(t) = 2(3t^2) +5(1t^0)
v(t) = 6t^2 +5 . . . . matches choice C
The answer is D because Sine and cosine equals 90.

Answer:
Number of rocks and fossils collected by you is 1 and 24 respectively
Number of rocks and fossils collected by your friend is 3 and 12 respectively
Step-by-step explanation:
Let the number of Rocks you collect be x
Let the number of Fossils you collect be y
Then the total number pf objects you collected will be
x + y = 25
x = 25 - y------------------------------(1)
Your friend collects three times as many rocks and half as many fossils as you.
This can be written as
-------------------(2)
Substituting (1) in (2)
Grouping the like terms we get,
y= 24
Substituting y value in equation(1) we get
x = 25 - 24
x= 1
Friends collects 3 times rock
so collects 3x =3(1) = 3rocks
Also he collects half as many fossils
That is
Answer:
The new side lengths will be 24 inches and 40 inches
Step-by-step explanation:
Here, given the width and length of a rectangle and we want to create a scaled copy using a scale factor of 4, we want to know the new side lengths
What we simply want to do here is to scale up or dilate the side lengths of the rectangle using a scale factor of 4
Hence, the new side lengths will be (4 * 6) inches and (10 * 4) inches
The new side lengths will be 24 inches and 40 inches
