A car’s velocity increases from 4.2m/s to 14.8 m/s, E, in 2.5 sec. What is its acceleration?

Answers

Answer 1

The acceleration is 4.24 m^2/s

What is acceleration?

They are accelerations and vector quantities. The direction of an object's acceleration is determined by the direction of the net force acting on it. Acceleration describes the rate at which a speed changes over time.

The velocity is changing over time. The velocity is actually changing at a constant rate of 10 m/s per second. If an object's velocity is changing, it is said to be accelerating; it has acceleration.

According to question,

Acceleration = final velocity- initial velocity/ time

Final velocity = 14.8 and initial velocity = 4.2

Hence, acceleration = 14.8-4.2/2.5

=10.6/2.5

=4.24.

The acceleration is 4.24 m^2/s.

What is an exponential function?

An exponential function is modeled according to the following rule:

[tex]y = ab^x[/tex]

In which the parameters are described as follows:

a is the initial value of the function, that is, the value of the function when x = 0.b is the rate of change of the function.

Lisa's function is already given, while for Xavier's, the parameters are given as follows:

a = 200, b = 270/200 = 1.35.

Hence his function is:

[tex]g(x) = 200(1.35)^x[/tex]

In 5 years, the amounts in each account will be given by the numeric values of the functions as follows:

Lisa: [tex]f(5) = 250(1.25)^5 = 763[/tex]Xavier: [tex]g(5) = 200(1.35)^5 = 897[/tex]

The positive difference is given by the subtraction of the greater amount by the lesser amount, hence:

897 - 763 = $134.

find the larger of 2 consecutive intergers if 4 times the smaller is 53 more than 3 times the larger

Answers

The larger of the two consecutive numbers is 57

What is a consecutive number?

Numbers that follow one another sequentially are known as consecutive numbers. Every time there are two numbers, there is a difference of 1 between them. If n is a number, then examples of consecutive numbers would be n, n+1, and n+2.  and 1, 2, 3, 4, 5, and so on.

From the question,

Let's say the smaller integer is x

Then the larger integer will be (x + 1)

According to the question,

4 times the smaller = 4x

3 times the larger = 3(x + 1)

⇒ 4x = 3(x + 1) + 53

⇒ 4x - 3x = 56

⇒ x = 56

(x + 1) = 57

Therefore, the larger of the two consecutive numbers is 57

Answers

a) Domain of the function 0 ≤ d ≤ 21 (0,21)

Range of the function 0 ≤ B ≤ 400 (0,400)

b) Estimate to the nearest hundreds for B(0) is 200

c) Ebony's bank balance first reached $0 on day 12 can be shown as functional notation as - we can add the number 12 below the first point reaching the horizontal axis.

d) Ebony's bank balance remained $0 from day 12 through day 15. The segment which represents the information is - segment 4.

(a) Domain: the collection of values used as input or arguments for the function.

Range: Either the codomain or the function's image is mentioned.

For three weeks, Ebony's bank account was active (21 days). then the domain is 0 ≤ d ≤ 21 (here 'd' refers to day)

Her highest balance was $400 and her lowest was zero, so the range is  0 ≤ B ≤ 400. (Here, 'B' refers to Balance)

(b) When d = 0, the graph's highest point, which represents her highest balance of $400, is displayed. This means that on the first day, the point will probably only be half as high as the highest point. Therefore, we may calculate the nearest hundred for B(0) is about equal to 0.5 * 400 = 200.

(c) In other words, the line of the function first touches the horizontal axis at d = 12; the balance first reached $0 on day 12. Below the first point that reaches the horizontal axis, we can add the number 12.

(d) From day 12 through day 15, the bank balance stayed at zero dollars; this is shown by the vertical axis of segment 4 of graph 4.

There are two cars, green car (gc) and a blue car (bc). gc is $15 plus $0.50 per mile driven, bc is $25 plus $0.15 per mile. how many miles do both cars have to drive to cost the same amount?

Answers

The number of miles that both the green car and the blue car have to drive to cost the same amount is equal to 28.5 miles.

The number of miles both cars have to travel to cost the same amount can be determined using an algebraic expression. An algebraic expression can be defined as a mathematical equation consisting of both letters and numbers.

As the green car (gc) cost $15 plus $0.50 per mile and the blue car (bc) costs $25 plus $0.15 per mile, an algebraic expression for this problem can be given as follows;

15 + 0.50(x) = 25 + 0.15(x)

Solving for x;

0.50x - 0.15x = 25 - 15

0.35x = 10

x = 10 / 0.35

x = 28.5

Hence, both cars have to drive 28.5 miles to cost the same amount.

At the local dairy farm, Kareem buys a 32-oz container of yogurt for $2.56. Jonah buys a 6-oz container of yogurt for $0.48. Are the cost, y, in dollars and the amount of yogurt, x, proportional?

The quantities Choose... proportional.

Answers

The dollar cost y and the amount of yogurt are proportionate

The formula is y = 0.08x

If y fluctuates as directly as x, you may express it as y = kx.

Where k is the proportionality constant.

 Determine the value of the proportionality constant. When y = 2.56 and x = 32, you get:

y = kx

k = y/x

k = 2.56/32

k = 0.08

 The equation is then: y = 0.08

 Check to see if they are directly proportionate. Substitute the amount of yogurt purchased by Jonah. The outcome must be $0,48:

y = 0.08 (6) (6)

y = 0.48

Answers

An exponential model to represent this situation  [tex]P =17000 (0.96)^{t}[/tex]

What is exponential growth of population?

Exponential growth occurs when a population's per capita growth rate remains constant regardless of population size, causing the population to grow faster and faster as it grows larger.

In exponential growth, the per capita (per individual) growth rate of a population remains constant regardless of population size, causing the population to grow faster and faster as it grows larger. In nature, populations may grow exponentially for a time, but they are eventually constrained by resource availability.

Given that,

P represents population, and

t the number of years of growth.

As we know,

P = [tex]a(b)^{t}[/tex]  

[here 'a' is the initial amount of population and 'b' is the amount of growth or shrink]

To get 'b,' start at 1 and either add or remove the decimal growth rate depending on whether it is rising or decreasing.

In this case a = 17,000, it is the value of population at the time zero.

As the population decreases 4% each year, then b = 1-0.04 = 0.96

So, the equation becomes, P = [tex]17000 (0.96)^{t}[/tex]
