A body moving with a velocity of 20 m/s begins to accelerate at 3 m/s2. How far does the body move in 5 seconds?A. 196 m
B. 137.5 m
C. 260 m
D. 162.5 m

Answers

Answer 1

Answer: Answer is B. According to the equation of motion s = vt + 1/2 at2 Where s is distance covered, v is velocity, a is acceleration and t is time taken. So, by putting all the values, we get s = (20)(5) + 1/2 (3)(5)2 s = 100 + 1/2 (3)(25) s = 100 + 1/2 75 s = 100 + 37.5 s = 137.5 meters

Once Isabel rented the warehouse space, she decided to post ads on several social media sites to advertise her online bookstore. Let m represent the number of months the ads have been posted. Isabel finds that the function below describes the number of books sold as a function of the number of months her ads have been posted. f(x) = 1000(∛x) + 1000 How many books were sold after 8 months? (3 points)

Graph the function. (10 points)

Answers

The solution is 3000 books

The number of books sold after 8 months is given by the equation

f ( 8 ) = 3000 books

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

f ( x ) = 1000 ∛( x ) + 1000 be equation (1)

Let the number of months be represented as x

Now , the number of books sold by Isabel for 8 months is given by the equation ,

when x = 8

Substitute the value of x = 8 in the equation , we get

f ( x ) = 1000 ∛( x ) + 1000

f ( 8 ) = 1000 ∛8 + 1000

f ( 8 ) = 1000 ( 2 ) + 1000

f ( 8 ) = 2000 + 1000

f ( 8 ) = 3000 books

Therefore , the value of f ( 8 ) is 3000 books

Hence , the number of books sold is 3000 books
