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.
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.
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.
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)

Which statement is true regarding the graphed functions?
Options:
• f(4) = g(4)
• f(4) = g(-2)
•f(2) = g(-2)
•f(-2) = g(-2)
Answer: D. f(-2)=g(-2)
Step-by-step explanation:
This problem is asking which of the options are correct. Looking at the options, you can see that it is saying that the same x-coordinate on f(x) and g(x) gives you the same solution. Therefore, we want to find the solution of the graph.
Looking at the graph, we can see that the solution is (-2,4). We know this because that is the intersection point of f(x) and g(x). Therefore, D is the correct answer.

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.
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:

20+(y-10)+4y help please
Answer:
below
Step-by-step explanation:
[tex]20 + (y - 10) + 4y \\20 + y -10 + 4y \\20 - 10 + y + 4y \\10 + 5y[/tex]
The simplification form of the expression 20 + (y - 10) + 4y is 5y + 10 after adding like terms.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The linear expression is:
= 20 + (y - 10) + 4y
As we know, the linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.
If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.
After simplifcation:
Adding like terms:
= 5y + 10
Thus, the simplification form of the expression 20 + (y - 10) + 4y is 5y + 10 after adding like terms.

What is rounding for math
Answer:
Step-by-step explanation:
Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. But 76 goes up to 80. There are many ways to round.
Hey there!
Rounding is estimating a number to its closest value. Let's say for example the number 226. If you round 226 to the nearest ten, you would get 230. This is what rounding is.
Hope this helps!

Gavin, Colin and Dan share some sweets in the ratio 2:4:3. Gavin gets 24 sweets
How many more sweets does Colin get over Dan?
Answer:
12
Step-by-step explanation:
[tex]G:C:D\\----\\2:4:3[/tex]
Gavin has 24 sweets which is 2 units.
2 units = 24 sweets
1 unit = [tex]24\ sweets \div 2 = 12\ sweets[/tex]
Colin has 4 units, while Dan has 3 units.
Colin has 1 unit more than Dan.
Since 1 unit is 12 sweets, Colin has 12 more sweets than Dan.

How do you do this question?
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)

Classify the two given samples as independent or dependent.Sample 1:The gas mileage for 48 trucksThe gas mileage for 48 trucks nothingSample 2:The gas mileage for the same 48 trucks after receiving a tuneupThe gas mileage for the same 48 trucks after receiving a tuneup nothingChoose the correct answer below.A.The two given samples are independent because different vehicles were sampled.B.The two given samples are dependent because the same vehicles were sampled.C.The two given samples are independent because the same vehicles were sampled.D.The two given samples are dependent because different vehicles were sampled.
Answer:
Option B
Step-by-step explanation:
The two samples are paired as the gas mileage of 48 trucks is measured for before tuneup and after tuneup. The gas mileage of 48 trucks will be affected by receiving tuneup. As the same 48 trucks are selected for tuneup, so the sample will be dependent. Hence the two samples are dependent because the same trucks are sampled.

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