Answer:

Step-by-step explanation:
Given

Required
The speed of the particle
To do this, we simply differentiate the position function
i.e.

So, we have:

Differentiate


So, the speed function is:

Composite Figures in Geometry:
In geometry, if a given geometrical figure is made up of two or more geometrical figures, we call it a composite figure. When a composite figure is a three-dimensional geometrical figure, it has a volume that is equal to the amount of space that is inside the figure.
I hope that helps!
the math behind it:
your equation looks like this: .25x = 10
then you divide both sides by .25 and then ur equation looks like this: x=40
by the way the variable x stands for the number you are looking for. and since x=40, the number you are looking for is 40
well i hope i helped!
Answer: the hourly fee for the rototiller is $3
Step-by-step explanation:
Let h represent the hourly fee for renting the rototiller.
The rental company charged an initial fee of $43 with an additional fee per hour. Assuming that they rented the rototiller for x hours. This means that if they rented the rototiller for x hours, the total amount that they would pay is
43 + hx
If they paid $64 after renting the rototiller for 7 hours, the equation that models this problem would be
43 + 7h = 64
7h = 64 - 43 = 21
h = 21/7 = $3
Answer:
To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same
Step-by-step explanation:
A monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers. That means that
42,5x,14x12,2pq
