A Particle Moves Along The R-axis So That Its Velocity Vat Any Given Time T, For 0 St $ 16, Is Given

Answers

Answer 1

Given: The velocity function of a moving particle as

[tex]V(t)=e^{2sint}-1[/tex]

To Determine: The time at which the acceleration equals to zero

Solution

Note that at time t=0, the particle is at origin, so

[tex]\begin{gathered} V(0)=e^{2sin0}-1 \\ V(0)=e^{2\times0}-1 \\ V(0)=e^0-1 \\ V(0)=1-1 \\ V(0)=0 \end{gathered}[/tex]

Determine the acceleration function

The acceleration of a particle is the rate of change of velocity or the derivative of the velocity function. Therefore,

[tex]A(t)=\frac{dV(t)}{dt},or,A(t)=V^{\prime}(t)[/tex][tex]\begin{gathered} V(t)=e^{2sint}-1 \\ let:u=2sint:\frac{du}{dt}=2cost \\ V(t)=e^u \\ \frac{dV(t)}{du}=e^u=e^{2sint} \\ A(t)=\frac{dV(t)}{dt}=\frac{dV}{du}\times\frac{du}{dt} \\ A(t)=e^{2sint}\times2cost \\ A(t)=2e^{2sint}cost \end{gathered}[/tex]

When the acceleration is equal to zero, then we have

[tex]\begin{gathered} A(t)=0 \\ 2e^{2sint}cost=0 \end{gathered}[/tex]

Let us plot the graph of the acceleration function

The time for given interval for which the acceleration is zero are

[tex]t=\frac{\pi}{2},\frac{3\pi}{2},\frac{5\pi}{2},\frac{7\pi}{2},\frac{9\pi}{2}[/tex]

ence, thre first time the acceleration is zero is π/2 or 1.571

The cost to travel X miles east or west on a train is the same. The function for the cost
c(x) = 0.75|x| + 25.

Describe how c(x) is related to its parent function and interpret the function in the context of the situation.

Answers

C(x) is related to its parent function c(x) = 0.75|x| + 25.

The function in the context of the situation illustrated that the cost is the same.

How to illustrate the information?

It should be noted that a function is used to show the relationship between the variables.

In this case, the cost to travel X miles east or west on a train is the same. The function for the cost is given as c(x) = 0.75|x| + 25.

Let East = positive direction

Let West = negative direction

Let the travel distance in East = x

Travel distance for West = -x mile

The cost to travel East x miles will be:

= 0.75(x) + 24

= 0.75x + 25

The cost to travel West will be:

c(-x) = 0.75x + 25

This shows that the cost will be the same even though there in different directions.

find the measure of each angle. JKL=5x+4 and LKM=3x

Answers

Angle JKL has a measure of 24 degrees while angle LKM has a measure of 12 degrees

How to determine the measure of each angle?

The possible question is added at the end of the solution and as an attachment

From the attached figure, we have the following angles

Angle 1: Angle JKL = 5x+4Angle 2: Angle LKM = 3x

From the attached figure, we can see that:

Angle 1 is twice the measure of angle 2

This is so because, the angle 1 is the vertex angle of an isosceles triangle

While the angle 2 is half of it

So, we have

Angle 1 = 2 * Angle 2

Substitute the known values in the above equation

So, we have

2 * 3x = 5x + 4

Evaluate the product

So, we have

6x = 5x + 4

Evaluate the like terms

x = 4

Substitute x = 4 in the equations JKL=5x+4 and LKM=3x

So, we have

JKL= 5 x 4 + 4

LKM = 3 x 4

Evaluate the equations

So, we have

JKL= 24

LKM = 12

Hence, the measures of the angles are JKL= 24 and LKM = 12, respectively

The value of expression c − a + b d on simplification is (-10101.2).

As per question we need to solve the given equation i.e., c − a + b d

And we are provided with the values of a, b , c and d.

Here we have ,

a=78,

b=−716

c=0.8

and d=14

The given equation is,

c − a + b d

Now we need to substitute the value of a, b, c and d. On substituting the value of a, b, c and d , we get

(0.8) - 78 + (-716) (14)

= (0.8) - 78 - 10024

= (-10101.2)

So, we can conclude that the value of given expression on simplification is  (-10101.2).

Integers are like the above ones, but also includes the zero and negative numbers.

Rationals are the ones that can be written as a quotient between two integers, and irrationals are these ones that can't be written like that.

Finally, real numbers are all the numbers.

In this case we have the square root of a prime number, √2, this is always a irrational number.

Given : Solution A contains 20% alcohol, while Solution B contains 6% alcohol.

It is  also given that Charlie uses 300 milliliters of Solution A.

Let's say that the mixture contained x ml of the 6% solution B.

x + 300 = resulting mixture of 12 % alcohol.

20% (300) + 6% (x) = 12% (x+300)

How many of each type of shirt were sold?

Answers

A store sold 22 colored shirts and 8 white shirts.

Let x be the number of colored shorts and y be the number of white shirts.

A store sold 14 more colored shirts than white shirts.

so, we get an equation,

x = y + 14                       ....................(1)

The white shirts cost $9.95, and the colored shirts cost $10.50. The store sold $310.60 worth of shirts.

So we get an equation,

10.50x + 9.95y = 310.60           .............(2)

Substitute above value of x in equation (2)

10.50(y + 14) + 9.95y = 310.60          

10.50y + 147 + 9.95y = 310.60          

20.45y = 310.60 - 147

20.45y = 163.6

y = 8

Substitute above value of y in equation (1)

Answers

Based on the equations given, the best comparison between them is that they are intersecting but not perpendicular.

How to know lines that are perpendicular?

When lines are perpendicular to each other, one line will have a slope that is the negative reciprocal of the other. For instance, if the slope of one line is 2, the slope of the perpendicular line will be -1/2.

Parallel lines will have the exact same slope.

The slope of the first line is:

2x - 7y = -5

(2x - 7y = -5) x 1/7

2/7x - y = -5/7

Slope = 2/7

The slope of the second line is:
x - 3y = 4

(x - 3y = 4) x 1/3

1/3x - y = 4/3

Slope = 1/3

The slopes are neither negative reciprocals nor the same so the lines must be intersecting but not perpendicular.

3. A bus travels a distance of 60 km at a steady speed of 60 km/h. (a) Does the distance travelled vary directly with time?If the journey takes 8 hours, find its speed.​

Answers

a) The distance that the bus traveled varies directly with time.

b) If the journey of 60 km takes 8 hours, the speed of the bus is 7.5 km/h.

What is the relationship between distance and speed?

The relationship between distance and speed can best be explained below:

For a constant speed, for example, 60 km/h, the distance traveled, 60 km, is proportional to the time used.

But if the distance is fixed at 60 km, the time it takes the bus, for example, 8 hours, is inversely proportional to the speed.

Total distance = 60 km

Steady speed = 60 km/h

Thus, for every kilometer, the bus takes one minute (60/60) and for every minute, the bus travels a kilometer.

Procedure:

• Finding the angles

We know that C = 90° as the image shows the symbols. Also, we know that the sum of the interior angles of a triangle are 180°. Then, to get A we have to do the following:

[tex]A+B+C=180[/tex]

Replacing the values we know:

• Finding side ,a

Using trigonometric functions, we can get a.

[tex]\tan (A)=\frac{a}{b}[/tex]

As we already know the value of A and b, we can isolate for a:

[tex]a=b\cdot\tan (A)[/tex]

Replacing the values:

[tex]a=19\cdot\tan (20)\approx6.92[/tex]

• Finding side ,c

Finally, using the Pythagorean Theorem, we can calculate c:
