F(x) = x^3 (a) computer f(x)dx (b) computer the approximation L, and T, for n=4, 8, and 16 for the integral in part (a). For each of these, compute the corresponding absolute error.

Answers

Answer and Step-by-step explanation:

F(x) = x^3 (a)

then

compute f(x) dx for each of these, compute the corresponding absolute error.

Solution:  f(x) = x3

            F(x) d(x) = 3x2

The absolute error are ∆x= |x-ẋ|, ∆f=|f(x) – f(ẋ)|

(b) Compute the approximation L, and T, for n=4, 8, and 16 for an integral part.

The linear (L) approximation of function f(x) = x3, n= 4

  f(4) = (4)3 = 64 and f”(4) = 3(4)2 = 48

The linear approximation is  L4(x) = f (4) + f’(4)(x-4)

                       

                           = 64 + 48 (x-4)

For n= 8,

  f(8) = 512 and f,(8)= 3(8)2= 192

The linear approximate is L8(x) = f(8) + f’(8)(x-8)

Similarly for n= 16 the linear approximate is L16(x) = f (16) + f (16) (x-16)

The approximation for T, trapezoidal rule is:

a ʃb f(x)dx = Tn

for n = 4 the T approximation is:

T4  =a ʃb  x3 dx

For n= 8 :

T8 = a ʃb x3 dx

For n= 16 : T16= a ʃb x3 dx.

Answers

Answer:

its the last one y = -1/3x + 3

Answer:

y= - 1/3x + 3

Step-by-step explanation:

Use 2 points and plug them into the slope formula

(0,3)(3,2)

Slope =(y2−y1)/(x2−x1)

                 (2−3)/(3−0)

                      −1/3

Slope is negative 1/3

Now look on the graph where the line goes through 0,3

This is the y intercept

How do you do this question?

Answers

Step-by-step explanation:

f(x) = 38 cos(x²)

Use chain rule to take the derivative.

f'(x) = -38 sin(x²) (2x)

f'(x) = -76x sin(x²)

Use product rule and chain rule to take the derivative.

f"(x) = -76x cos(x²) (2x) + (-76) sin(x²)

f"(x) = -152x² cos(x²) − 76 sin(x²)

How do you determine the last digit in any measured number? Select one: Round up to one digit larger than the smallest precisely known digit or marking. Estimate one digit past the smallest precisely known digit or marking. Consult the unique rule for each type of lab measurement and instrument. Record the digit corresponding to the smallest precisely known digit or marking.

Answers

Answer:

Estimate one digit past the smallest precisely known digit or marking

Step-by-step explanation:

To determine the last digit in any measured number : Estimate one digit past the smallest precisely known digit or marking

This is employed mostly when trying to round off a measured or calculated number to a precise number of digits and in other to determine the last digit in the given number we will have to estimate one digit past the smallest precisely known digit

The true statement about how to determine the last digit in any measured number is (b) Estimate one digit past the smallest precisely known digit or marking

A measured number is a number derived from taking measurements (take for instance weight, length, distance etc.)

The number that ends the measured number (i.e. the last digit) is always an estimated digit.

This means that, we have to count one digit past the supposed last digit and then estimate (i.e. approximate)

Hence, the true option is (b)

five times a number plus 5 has the same value as twice the number plus 10

Answers

Answer: x=5/3

Step-by-step explanation:

For this problem, we can use teh information given to write out an equation and solve. Let's use x for the unknown number.

5x+5=2x+10

The left side of the equation comes from the part that says "five times a number plus 5". That is modeled above. The right side of the equation comes from "has the same value as twice the number plus 10".

5x+5=2x+10                     [subtract both sides by 2x]

3x+5=10                           [subtract both sides by 5]

3x=5                                [divide both sides by 3]

x=5/3

Now, we have found the unknown number, x=5/3.

Find:

Probability of choosing number

Suppose we take a look at a three-dimensional space with perpendicular x-, y- and z-axes.  If we let one of these three variables be a constant, then the resulting area is a plane (with two-dimenions).  if we held z constant, then the plane would be the xy plane, and any two lines lying entirely in this plane are deemed to be "coplanar:"  they lie in the same plane.

Angela is shopping for pet supplies and needs to buy a kennel and several toys. At Paws R Us, she would pay $50.75 for the kennel and $3.75 for each pet toy. At Truth or Tail, she would pay $43.25 for the kennel and $5 for each pet toy. Write an inequality to represent t, the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option.​

Answers

Answer: t>6

Step-by-step explanation:

Amount to pay = Cost of kennel + (Cost per toy )x (Number of toys)

Let t = the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option.​

Given, At Paws R Us, she would pay $50.75 for the kennel and $3.75 for each pet toy.

Amount to pay =  $(50.75 + 3.75t)

At Truth or Tail, she would pay $43.25 for the kennel and $5 for each pet toy.

Amount to pay =  $(43.25 + 5t)

According to the question , we have

50.75 + 3.75t < 43.25 + 5t

Subtract 3.75t from both sides

50.75+ 3.75t -3.75t   < 43.25 + 5t -3.75t

⇒ 50.75< 43.25 +1.25 t

Subtract  43.25 from both sides, we get

50.75 - 43.25 < 1.25 t

⇒  7.5< 1.25 t

Divide both sides by 1.25 we get

⇒   6<t

Hence, the required inequality to represent t, the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option:
