The Taylor polynomial t3(x) for the function f(x) = xe−7x centered at a is:

t3(x) = f(a) + f'(a)(x-a) + f''(a)(x-a)2/2! + f'''(a)(x-a)3/3!

To find the Taylor polynomial t3(x), we need to compute the first three derivatives of f(x):

f(x) = xe−7x

f'(x) = e−7x − 7xe−7x

f''(x) = 49xe−7x − 14e−7x

f'''(x) = −343xe−7x + 147e−7x

Next, we evaluate these derivatives at x = a and simplify:

f(a) = ae−7a

f'(a) = e−7a − 7ae−7a

f''(a) = 49ae−7a − 14e−7a

f'''(a) = −343ae−7a + 147e−7a

Now, we plug these values into the formula for t3(x):

t3(x) = ae−7a + (e−7a − 7ae−7a)(x-a) + (49ae−7a − 14e−7a)(x-a)2/2! + (−343ae−7a + 147e−7a)(x-a)3/3!

We can simplify this expression to obtain the final form of t3(x):

t3(x) = ae−7a + (x-a)e−7a(1-7(x-a)) + (x-a)2e−7a(49a-7) + (x-a)3e−7a(-343a+147)/6

The points whose distance from (-3,-4) is the square root of 10 and whose distance from (1,0) is the square root of 10 are given by the circle (x+3)^2 + (y+4)^2 = 2, which has center (-3,-4) and radius sqrt(2).

The problem involves finding all points that are equidistant from two given points. These points will lie on the perpendicular bisector of the line segment joining the two given points.

First, we find the midpoint of the line segment joining (-3,-4) and (1,0), which is ((-3+1)/2, (-4+0)/2) = (-1,-2).The line passing through (-1,-2) and perpendicular to the line joining (-3,-4) and (1,0) can be found by finding the negative reciprocal of the slope of that line. The slope of the line joining (-3,-4) and (1,0) is (0-(-4))/(1-(-3)) = 4/4 = 1. So the slope of the perpendicular line is -1/1 = -1.

Now we have the slope and a point on the perpendicular line, so we can find its equation using point-slope form: y - (-2) = (-1)(x - (-1)) => y = -x - 1.

Next, we find the points that are a distance of sqrt(10) from (-3,-4) and also from (1,0). Let (x,y) be a point on the line y = -x - 1. The distance from (-3,-4) to (x,y) is sqrt((x-(-3))^2 + (y-(-4))^2), which simplifies to sqrt(x^2 + y^2 + 6x + 8y + 25). Similarly, the distance from (1,0) to (x,y) is sqrt((x-1)^2 + y^2). Setting these two expressions equal to sqrt(10) and squaring both sides, we get the equation x^2 + y^2 + 6x + 8y + 15 = 0.

We can complete the square to rewrite this equation as (x+3)^2 + (y+4)^2 = 2. This is the equation of a circle centered at (-3,-4) with radius sqrt(2). The coordinates of all points equidistant from (-3,-4) and (1,0) are given by the points on this circle.

The first partial derivatives of f(x,y) at the point (3,1) are:
∂f/∂x(3,1) = 3
∂f/∂y(3,1) = -12

To find the first partial derivatives of f(x,y) at the point (3,1), we need to find the partial derivative with respect to x and y, respectively, and then substitute x=3 and y=1.

So, let's begin with the partial derivative with respect to x:
∂f/∂x = 3 - 0  (since the derivative of 3x with respect to x is 3, and the derivative of 4y with respect to x is 0)

Now, we can substitute x=3 and y=1 into this expression:
∂f/∂x(3,1) = 3 - 0 = 3

So, the partial derivative of f(x,y) with respect to x at the point (3,1) is 3.

Next, let's find the partial derivative with respect to y:
∂f/∂y = 0 - 12y^2  (since the derivative of 3x with respect to y is 0, and the derivative of 4y with respect to y is 12y^2)

Now, we can substitute x=3 and y=1 into this expression:
∂f/∂y(3,1) = 0 - 12(1)^2 = -12

So, the partial derivative of f(x,y) with respect to y at the point (3,1) is -12.

Therefore, the first partial derivatives of f(x,y) at the point (3,1) are:

Answer:

A. 24 inches

Step-by-step explanation:

A cube is defined by having all three lengths being of equal size,

[tex]V = L^3[/tex]

so to find length from the volume of a cube, you must take the cube root of the volume.

[tex]\sqrt[3]{V} = L[/tex]

[tex]\sqrt[3]{216} = 6[/tex]

That means each side of the cube has a length of 6 inches.

The formula for the perimeter is give below the cube diagram.

[tex]P = 4L[/tex]

Which means we just take the length we found above and multiply it by 4.

[tex]4*6 =24[/tex] inches

Therefore 24 inches is your answer.

The phasor method involves converting the sinusoidal functions into phasors, which are complex numbers representing the amplitude and phase of the sinusoidal function. The phasor for a sinusoidal function y = A sin(ωt + φ) is A e^(iφ), where A is the amplitude and φ is the phase angle.

(a) To find the amplitude of y, we need to add the phasors of y1, y2, and y3. The phasor for y1 is 11 e^(i0) = 11, the phasor for y2 is 21 e^(i30°), and the phasor for y3 is 7.0 e^(-i50°). Therefore, the phasor for y is:

Y = 11 + 21 e^(i30°) + 7.0 e^(-i50°)

To find the amplitude of Y, we can take the magnitude of this phasor:

|Y| = sqrt[(11)^2 + (21)^2 + (7.0)^2] = 24.2

Therefore, the amplitude of y is 24.2.

(b) To find the phase constant of y, we need to find the angle that the phasor Y makes with the positive real axis. We can write the phasor Y in rectangular form:

Y = (11 + 21 cos 30° - 7.0 cos 50°) + (21 sin 30° - 7.0 sin 50°) i

The angle that the phasor Y makes with the positive real axis is:

tan^(-1)[(21 sin 30° - 7.0 sin 50°) / (11 + 21 cos 30° - 7.0 cos 50°)]

Using a calculator, we find that this angle is approximately -6.5°. Therefore, the phase constant of y is -6.5°, or we can say that the phase angle of the phasor Y is -6.5°.

The probability that Ali misses 4 shots out of 25, given that he has a 3-point shooting percentage of 9/10 or 0.9, is approximately 0.1394, or about 13.94%.

The probability of an event occurring is defined by probability. There are numerous real-life scenarios in which we must forecast the outcome of an occurrence.

We can use the binomial distribution to find the probability that Ali misses 4 shots out of 25, given that he has a 3-point shooting percentage of 9/10 or 0.9.

Let X be the number of missed shots out of 25 attempts. Since each shot is either a miss or a make, this is a binomial distribution with n = 25 and p = 1 - 9/10 = 1/10. We want to find P(X = 4), which is:

P(X = 4) = (25 choose 4) * (1/10)⁴ * (9/10)²¹

where "25 choose 4" is the number of ways to choose 4 shots out of 25.

Using a calculator, we can evaluate this expression to find:

P(X = 4) ≈ 0.1394

A value of r greater than 0.40 indicates a stronger correlation than 0.40.

The correlation coefficient, denoted as "r," measures the strength and direction of the linear relationship between two variables. The value of r ranges from -1 to 1. When the absolute value of r is closer to 1, it indicates a stronger correlation. In this case, a value of r greater than 0.40 suggests a stronger positive correlation than 0.40.

This means that as one variable increases, the other variable tends to increase as well, and the relationship between the variables is more pronounced. For example, if the correlation coefficient is 0.60, it indicates a stronger positive correlation than 0.40. Similarly, if the correlation coefficient is 0.90, it indicates an even stronger positive correlation. On the other hand, if the correlation coefficient is negative, such as -0.60 or -0.90, it indicates a stronger negative correlation.

Answer:

z = 56

Step-by-step explanation:

124 and Z form a straight line so they will add to 180

124+z = 180

z = 180-124

z = 56

Answer:

z = 56°

Step-by-step explanation:

We know that vertically opposite angles are equal.

∴ y = 124°

We know that angles in a straight line are added up to 180°.

∴ y + z = 180

124 + z = 180

z = 180 - 124

z = 56°

x = 56° ( vertically opposite angles ⇒ x = z )

The composite function is c(x(t)) = 3(2-6t)^2 - 7, and its derivative with respect to t is dc/dt = -72 + 216t.

To write the composite function, we substitute the expression for x(t) into c(x), giving c(x(t)) = 3(2-6t)^2 - 7.

To find the derivative of this composite function with respect to t, we use the chain rule:

dc/dt = (dc/dx) * (dx/dt)

where (dc/dx) is the derivative of c(x) with respect to x, and (dx/dt) is the derivative of x(t) with respect to t.

Taking the derivative of c(x) = 3x^2 - 7 with respect to x, we get:

dc/dx = 6x

And taking the derivative of x(t) = 2 - 6t with respect to t, we get:

dx/dt = -6

Substituting these values into the chain rule formula, we get:

dc/dt = (6x) * (-6)

Since x(t) = 2-6t, we can substitute that expression for x to get:

dc/dt = (6(2-6t)) * (-6)

Simplifying, we get:

dc/dt = -72 + 216t

So the composite function is c(x(t)) = 3(2-6t)^2 - 7, and its derivative with respect to t is dc/dt = -72 + 216t.

The area lying outside r=4sinθ and inside r=2+2sinθ is approximately 10.81 square units.

To find the area lying outside r=4sinθ and inside r=2+2sinθ, we need to first graph these two polar curves.

r=4sinθ is a cardioid, while r=2+2sinθ is a limacon with an inner loop.

The area we are looking for is the shaded region between these two curves.

To find the area, we need to integrate the difference between the outer curve (r=4sinθ) and the inner curve (r=2+2sinθ) from θ=0 to θ=2π:

Area = ∫(4sinθ)^2 - (2+2sinθ)^2 dθ from θ=0 to θ=2π

This simplifies to:

Area = ∫(16sin^2θ - 4 - 8sinθ - 4sin^2θ) dθ from θ=0 to θ=2π

Area = ∫(12sin^2θ - 8sinθ - 4) dθ from θ=0 to θ=2π

Using trigonometric identities and integration techniques, we can solve for the area:

Area = 4π - 8/3

Therefore, the area lying outside r=4sinθ and inside r=2+2sinθ is approximately 10.81 square units.

To find the Taylor series about 0 for the function t3sin(5t), we need to compute its derivatives up to the fourth order at x = 0. First, let's compute the first four derivatives:

f(t) = t^3sin(5t)

f'(t) = 3t^2sin(5t) + 5t^3cos(5t)

f''(t) = 6tsin(5t) + 30t^2cos(5t) - 25t^3sin(5t)

f'''(t) = 6sin(5t) + 90tcos(5t) - 75t^2sin(5t)

f''''(t) = 450cos(5t) - 270t sin(5t)

Next, we evaluate these derivatives at x = 0:

f(0) = 0

f'(0) = 0

f''(0) = 0

f'''(0) = 6

f''''(0) = 450

Finally, we can write the Taylor series about 0 for t3sin(5t) as:

t^3sin(5t) ≈ 0 + 0t + 0t^2 + (6/3!)t^3 + (450/4!)t^4

≈ (1/3!)t^3 + (1/4)t^4

Therefore, the first four nonzero terms of the Taylor series about 0 for t3sin(5t) are (1/3!)t^3 and (1/4!)t^4. These terms approximate the function t3sin(5t) near x = 0 with increasing accuracy as x gets closer to 0.

A = ∫²₋₁ [f(x) - g(x)] dx

A = ∫²₋₁ f(x) dx - ∫²₋₁ g(x) dx

A = ∫²₋₁ (2 · x + 6) dx - ∫²₋₁ (2 · x² + 2) dx

A = x²|²₋₁ + 6 · x|²₋₁ - (2 / 3) · x³|²₋₁ - 2 · x|²₋₁

A = 2² - (- 1)² + 6 · [2 - (- 1)] - (2 / 3) · [2³ - (- 1)³] - 2 · [2 - (- 1)]

A = 1 + 18 - 14 / 3 - 6

A = 8.333

Answer:

4 pizzas

Step-by-step explanation:

first of all, subtract parking fee from total:

52 - 4 = 48.

now divide by 12:

48/12

4.

so he he pays for 4 pizzas at $12 each (4 X 12 = 48).

and he pays $4 for parking.

48 + 4 = 52.
