Express the given integral as the limit of a riemann sum but do not evaluate: the integral from 0 to 3 of the quantity x cubed minus 6 times x, dx.

Answers

We will use the right Riemann sum. We can break this integral in two parts.
[tex]\int_{0}^{3} (x^3-6x) dx=\int_{0}^{3} x^3 dx-6\int_{0}^{3} x dx[/tex]
We take the interval and we divide it n times:
[tex]\Delta x=\frac{b-a}{n}=\frac{3}{n}[/tex]
The area of the i-th rectangle in the right Riemann sum is:
[tex]A_i=\Delta xf(a+i\Delta x)=\Delta x f(i\Delta x)[/tex]
For the first part of our integral we have:
[tex]A_i=\Delta x(i\Delta x)^3=(\Delta x)^4 i^3[/tex]
For the second part we have:
[tex]A_i=-6\Delta x(i\Delta x)=-6(\Delta x)^2i[/tex]
We can now put it all together:
[tex]\sum_{i=1}^{i=n} [(\Delta x)^4 i^3-6(\Delta x)^2i]\\\sum_{i=1}^{i=n}[ (\frac{3}{n})^4 i^3-6(\frac{3}{n})^2i]\\ \sum_{i=1}^{i=n}(\frac{3}{n})^2i[(\frac{3}{n})^2 i^2-6][/tex]
We can also write n-th partial sum:
[tex]S_n=(\frac{3}{n})^4\cdot \frac{(n^2+n)^2}{4}
-6(\frac{3}{n})^2\cdot \frac{n^2+n}{2}[/tex]

Final answer:

To express the integral from 0 to 3 of the function  as the limit of a Riemann sum, divide the interval into [tex]f(x) = x^3 - 6x[/tex] subintervals of equal width, find a Riemann sum, and then take the limit as n approaches infinity.

Explanation:

To express the given integral as the limit of a Riemann sum without evaluating, we represent the integral of the function [tex]f(x) = x^3 - 6x[/tex]split the interval [0,3] into n equal subintervals, each of width Δx = 3/n. Then we choose sample points x_i in each subinterval [x_{i-1}, x_i]. The Riemann sum is thus [tex]R = Σ(x_i^3 - 6x_i)Δx[/tex]en from i=1 to n and x_i is any point in the ith subinterval.

As n approaches infinity, which is equivalent to Δx approaching zero, the Riemann sums converge to the integral. The limit of the Riemann sum is then represented as lim_{n to ∞} R, which gives the exact area under the curve f(x) between 0 and 3, but we are not evaluating this limit.

which descriptions from the list below accurately describe the relationship between QRS and TUV

Answers

answer is A. similar

hope it helps

Answer:

A. Similar

Step-by-step explanation:

We are given the measurements of ΔQRS and ΔTUV as,

QR = RS = 4, QS = 2 with ∠Q = ∠S = 76°, ∠R = 28°

TU = UV = 12, TV = 6 with ∠T = ∠V = 76°, ∠U = 28°

Now, we see that,

These triangles have different side lengths. So, option C i.e. same sides is not correct.

Also, they are different in size. So, option D i.e. same size is not correct.

Since, they do not have same size, they cannot overlap each other. Thus, are not congruent. So, option B is also not correct.

Thus, we see that from SAS Similarity and the measurements,

QR = RS = 4 and ∠R = 28°

TU = UV = 12 and ∠U = 28°

Both the triangles are similar to each other.

Hence, option A is correct.

The length of a rectangle is 7mm longer than its width. It’s perimeter is more than 62mm. Let W equal the width of the rectangle, write an inequality and solve it

Answers

this is the answer to the question.
First of all, what is the equation for the perimeter of a rectangle? 
2(l + w) = p
Since we know the perimeter (p) is greater than 62 we can say:
2(l + w) > 62
It is also given that the length is 7 mm longer than the width, so we know the value of the length in terms of w (the width).
w = w
l = w + 7
Substitute l with (w + 7) into the equation:
2[(w + 7) + w] > 62
Now combine like terms in the parentheses
2(2w + 7) >62
Distribute the 2 into the terms in the parentheses
4w + 14 > 62
Subtract both sides by 14
4w > 62 - 14
Combine like terms
4w > 48
Divide both sides by 4
w > 48

Final answer: w > 48

2. Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. Show your work.

Answer:
m < C =
m < B =
m < A =
m < D =

Answers

Ans: 
1. m ∠C = 88°
2. m ∠B = 100°
3. m ∠A = 92°
4. m ∠D = 80°

Explanation:
∠A and ∠C are supplementary angles; therefore:
∠A + ∠C = 180° --- (A)

Since,
∠A = (x+2)°
and
∠C = (x-2)°

Plug-in the values in equation (A):
(A) => (x+2)° + (x-2)° = 180°
=> x° + 2° + x° - 2° = 180°
=> 2x° = 180°
=> x = 90°

Since x = 90°, therefore,
∠A = (x+2)° = 92°,
and
∠C = (x-2)° = 88°

Since ∠B and ∠D are supplementary angles; therefore,
∠B + ∠D = 180°
∠B + (x-10)° = 180°

Since,
x = 90°; therefore,

∠B + 80° = 180°
∠B = 100°

And since,
∠B + ∠D = 180°
and
∠B = 100°

Therefore,

∠D = 180° - 100°
∠D= 80°

Kevin is 2 times as old as Gabriela. 12 years, Kevin was 6 times as old as Gabriela.How old is Gabriela now

Answers

The answer is that kevin is 30 years old today and gabriela is 15 years old today. 

Final answer:

Gabriela's current age is found by setting up algebraic equations based on the information that Kevin is twice as old as Gabriela now, and was six times as old 12 years ago. Solving the equations, we find that Gabriela is 15 years old.

Explanation:

Finding Gabriela's Current Age:

The problem statement tells us that Kevin is currently 2 times as old as Gabriela and that 12 years ago, Kevin was 6 times as old as Gabriela. To solve for Gabriela's current age, let us use algebra. Let's denote Gabriela's current age as G and Kevin's current age as K. The given information can be translated into the following two equations:

K = 2G (Kevin is 2 times as old as Gabriela now)K - 12 = 6(G - 12) (12 years ago, Kevin was 6 times as old as Gabriela)

Substituting the first equation into the second, we get:

2G - 12 = 6(G - 12)

Expanding both sides:

2G - 12 = 6G - 72

Moving all terms involving G to one side and constant terms to the other side, we get:

2G - 6G = -72 + 12

-4G = -60

Dividing both sides by -4 to solve for G:

G = 15

So, Gabriela is currently 15 years old.

Given Sin x= 0.5, what is cos x?
Enter your answer as a decimal, round only your final answer to the nearest hundredth.

Answers

sin x = 0.5
sin x = 1/2
sin x = opp/hyp
therefore the ratio of opp/hyp = 1/2, (opp = 1, hyp = 2)

Find the opp side

1² + x² = 2²
1 + x² = 4
x² = 4 -1
x² = 3
x =√3

The opp side is √3

cos x = opp/hyp = √3/2 = 0.87 (round to the nearest hundredths)

If sin x = 0.5, cos x is approximately 0.87.

What are trigonometric identities?

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

To find cos x, we can use the identity: cos² x + sin² x = 1

We are given that sin x = 0.5.

We can substitute this into the identity to solve for cos x:

cos² x + sin² x = 1

cos² x + (0.5)² = 1

cos² x + 0.25 = 1

cos² x = 0.75

cos x = ±√0.75

We take the positive square root since cosine is positive in the first and fourth quadrants.

Evaluating the square root gives:

cos x ≈ 0.87 (rounded to two decimal places)

Therefore,

cos x is approximately 0.87.

30,000+8,000+700+2
3,000+800+70+2

Answers

That would be the second choice

Final answer:

The expanded form of 38,072 is 30,000 + 8,000 + 70 + 2, where each term represents the digit's value as a product of its place value.

Explanation:

The expanded form of the number 38,072 is written by separating each digit according to its place value and expressing it as the digit multiplied by the power of ten that represents its position. Therefore, the correct expanded form is:

30,000 + 8,000 + 70 + 2

To understand this, we can consider the place value of each digit in the number 38,072. The '3' is in the ten-thousands place, so it is 3 times 10,000, which is 30,000. The '8' is in the thousands place, so it is 8 times 1,000, which is 8,000. The '0' stands for no hundreds, so we skip it. The '7' is in the tens place, so it is 7 times 10, which is 70. Finally, the '2' is in the ones place, which is just 2.

ASAP What is the lateral area of this regular octagonal pyramid?? Explain your answer if you can plz thanks

Answers

The lateral area would be 298.7 cm².

The lateral area is the area of all of the lateral faces of the pyramid.  There are 8 triangles making up the lateral faces.  Each has a base of 6.6.  The formula for the area of a triangle is

A=1/2bh,

so we still need the height of the triangle.

The height of each lateral triangle is the slant height of the pyramid.  The slant height of the pyramid forms a right triangle with the height of the pyramid and the "radius" as it were of the pyramid.  Thus we use the Pythagorean theorem:

8²+8²=h²
64+64=h²
128=h²
√128=√(h²)
8√2 = h

Substituting this into our area formula we have:
A=1/2(6.6)(8√2)

We will go ahead and multiply this by 8, since there are 8 lateral faces:
LA=8(1/2)(6.6)(8√2)
LA = 298.7

You have a bag of bubble gum containing six grape, nine sour apple and five regular flavored pieces. You randomly pick one piece , give it to your friend, and then randomly pick another piece for yourself. What is the probability that both pieces are grape?

Answers

Final answer:

The probability that both pieces of bubble gum picked are grape flavored is 3/38, calculated by multiplying the probability of picking a grape piece first (6/20) and then another after the first is given away (5/19).

Explanation:

The question asks us to calculate the probability that both pieces of bubble gum picked from the bag are grape flavored. The bag contains six grape, nine sour apple, and five regular flavored pieces. To find the probability that both pieces are grape, we calculate the probability of picking one grape piece and then another grape piece after the first has been given away.

The total number of pieces initially is 6 (grape) + 9 (sour apple) + 5 (regular) = 20 pieces. The probability of picking a grape piece first is 6/20. After giving it away, there are 5 grape pieces left and the total number of pieces in the bag is now 19. The probability of then picking another grape piece is 5/19. To find the overall probability of both events occurring, we multiply the individual probabilities: (6/20) * (5/19) = 30/380 = 3/38.

Therefore, the probability that both pieces are grape is 3/38.
