Find the following indefinite integrals (show steps): (2 ) (323 + 5 +2') do ( b ) 5 + 2sin I di COS' I 8. A point P moves along the x-axis so that its position x at time t is given by I = 2t3 - 15t2 + 36t + 4. (a) Find the velocity and acceleration of P at time t.

Answers

Answer 1

a. The acceleration of P at time t is a(t) = 12t - 30.

b.  The indefinite integral of 5 + 2sin^2(x) dx is 6x - (1/2)sin(2x) + C, where C is the constant of integration.

(a) To find the velocity and acceleration of point P at time t, we need to differentiate the position function x(t) = 2t^3 - 15t^2 + 36t + 4 with respect to time.

Given:

x(t) = 2t^3 - 15t^2 + 36t + 4

Velocity:

The velocity of P is given by the derivative of the position function, which is the first derivative of x(t).

v(t) = dx/dt

Differentiating x(t) with respect to t:

v(t) = d/dt(2t^3 - 15t^2 + 36t + 4)

= 6t^2 - 30t + 36

Therefore, the velocity of P at time t is v(t) = 6t^2 - 30t + 36.

Acceleration:

The acceleration of P is given by the derivative of the velocity function, which is the second derivative of x(t).

a(t) = dv/dt

Differentiating v(t) with respect to t:

a(t) = d/dt(6t^2 - 30t + 36)

= 12t - 30

Therefore, the acceleration of P at time t is a(t) = 12t - 30.

(b) The indefinite integral of 5 + 2sin^2(x) dx:

∫(5 + 2sin^2(x)) dx

Using the identity sin^2(x) = (1/2)(1 - cos(2x)):

∫(5 + (2/2)(1 - cos(2x))) dx

∫(5 + (1 - cos(2x))) dx

∫(6 - cos(2x)) dx

Integrating term by term:

∫6 dx - ∫cos(2x) dx

Integrating each term:

6x - (1/2)sin(2x) + C

Therefore, the indefinite integral of 5 + 2sin^2(x) dx is 6x - (1/2)sin(2x) + C, where C is the constant of integration.

Answers

Answer:

42 should be in the blank.

Step-by-step explanation:

If you multiply 7/8 by 6, watch what happens...

7/8 *6 = 42/48

The denominators are the same, which shows how the equations are probably equal.

I know it might seem confusing because I'm not great at explaining, but I hope it helps! Have an awesome day c:

Answer: 42

Explanation:
First, you should divide both denominators to find what number you are multiplying by.

48/8 = 6

So now you know that the number you are multiplying by is 6. Now you want to multiply 7/8 by 6.

7/8 x 6 = 42/48

Find the value of the discriminant. Then describe the number and type of roots for the equation. 3x^2\:+\:4x\:-7=0

Answers

The given equation has two real and distinct roots.

The formula for the discriminant is b² - 4ac. For the given equation, 3x² + 4x - 7 = 0,

the value of a = 3, b = 4 and c = -7.Substituting these values in the formula for discriminant, we get:$$\begin{aligned}b^2-4ac&=4^2-4\times3\times(-7) \\&=16+84 \\&=100 \end{aligned}$$

Hence, the value of discriminant is 100.Using the value of the discriminant, we can determine the nature of roots. If the discriminant is positive, then the roots are real and distinct.

If the discriminant is zero, then the roots are real and equal.

If the discriminant is negative, then the roots are imaginary and conjugate.In this case, the discriminant is positive (100), so the roots will be real and distinct.

A uniform distribution is defined over the interval from 2 to 5.
What is the range of the random variable, x?
Over the range, what is the probability of the random variable, x?
What is the area of this uniform distribution?

Answers

The probability of x within this range is constant and equal to 1/3. The area under the uniform distribution curve is 1.

The range of the random variable, x, in a uniform distribution from 2 to 5 is [2, 5]. It represents the entire interval of possible values for x.

The probability of the random variable, x, in a uniform distribution is constant over the range. Since it is a uniform distribution, the probability density function is equal for all values within the range. Therefore, the probability of x taking any specific value within the range [2, 5] is the same, and it is given by 1 divided by the length of the range:

Probability of x = 1 / (length of range)

= [tex]P(x) = \frac{1}{5 - 2} = \frac{1}{3}[/tex]

The area of the uniform distribution is represented by the probability density function over the range. Since it is a uniform distribution, the probability density is constant within the range. Therefore, the area under the curve is equal to the length of the range multiplied by the constant probability density:

Area = (length of range) * (probability density) = (5 - 2) * (1 / (5 - 2)) = 3 * (1 / 3) = 1.

Hence, the area of the uniform distribution is 1.

water runs into a conical tank at the rate of 26 cubic inches per second. the tank stands point down and has a height of 11 inches and a base radius of 7 inches. how fast is the water level rising when the water is 5 inches deep?

Answers

The water level is rising at a rate of approximately 0.017 inches per second when the water is 5 inches deep.

Let's start with the formula for the volume of a cone.V= 1/3πr²h

Here, h is the height of the water level at a given time. We are given that water is flowing in at a rate of 26 cubic inches per second. Therefore, we can calculate the rate of change of volume as dV/dt = 26.The tank stands point down, which means that the apex of the cone is at the bottom and the base is at the top. The height of the tank is 11 inches, so when the water level is 5 inches deep, the remaining height of the tank that is empty is 11 - 5 = 6 inches.The radius of the tank at the base is 7 inches, which means that the radius of the top of the water level is proportional to the height of the water level. Therefore, the radius of the top of the water level when the water level is 5 inches deep is: r = (5/11) x 7 = 3.18 inches.Now we can use the formula for the volume of a cone to find the volume of water in the tank when the water level is 5 inches deep.

V= 1/3πr²h= 1/3 x π x (3.18)² x 5= 53.4 cubic inches

Now we can find the rate of change of height with respect to time using the formula

dV/dt = A dh/dt, where A is the area of the base of the tank.

A = πr² = π(7)² = 49π square inches.

Therefore, we have:

26 = 49π dh/dt

dh/dt = 26 / (49π)

dh/dt ≈ 0.017

The water level is rising at a rate of approximately 0.017 inches per second when the water is 5 inches deep.

Use the remainder Theorem to find the remainder for (x2- 2)/(x - 1) and state whether or not the binomial is a factor of
the polynomial.

Answers

Answer:

The remainder is -1

The binomial is not a factor of the polynomial

Step-by-step explanation:

In the algebraic division, there are 4 terms

Dividend ⇒ the term before the division signDivisor ⇒ the term after the division signQuotient ⇒ the answerRemainder ⇒ appear when the dividend not divisible by the divisor (the divisor is not a factor of the dividend)

The remainder theorem:

If you divide a polynomial f(x) by (x - h), then the remainder is f(h).You do not need to use the long division to find the remainder, just evaluate the polynomial when x = h to find the remainder.If h(h) = 0, then (x - h) is a factor of f(x)

Let us use it to solve the question

∵ The dividend is x² - 2

∴ f(x) = x² - 2

∵ The divisor is x - 1

∴ (x - h) = (x - 1)

h = 1

Let us find f(1)

∵ f(1) = (1)² - 2 = 1 - 2 = -1

∴ f(1) = -1

The remainder is -1

∵ f(1) ≠ 0

∴ x - 1 is not a factor of x² - 2

The binomial is not a factor of the polynomial

which equation in a standar form has a grpah that passes through the point (-4,2) and has a slope 9/2

Answers

Equation in standard form that has a graph that passes through point (-4, 2) and has slope of 9/2 is calculated to be as equal to -40.

The equation in standard form that has a graph that passes through the point (-4, 2) and has a slope of 9/2 is given by  :

Step 1: Recall the standard form of a linear equation

The standard form of a linear equation is Ax + By = C, where A, B, and C are constants.

Step 2: Substitute given values

The equation should pass through the point (-4, 2) and should have a slope of 9/2.

Therefore, the slope-intercept form of the equation is given by:

y - 2 = (9/2)(x + 4)

Multiplying through by 2, we have: 2y - 4 = 9(x + 4)2y - 4

= 9x + 36

Rearranging, we get: 9x - 2y

= -40

Therefore, the equation in standard form that has a graph that passes through the point (-4, 2) and has a slope of 9/2 is 9x - 2y

= -40.
