The given function is y = x³ and the interval on which we are finding the area is [0, 1].

Using right endpoints, the value of x that we use for each rectangle will be the right endpoint of the subinterval on which the rectangle is being constructed. We divide the interval [0, 1] into n equal subintervals of width Δx, where Δx = (b - a) / n = (1 - 0) / n = 1 / n. Thus, the ith subinterval has endpoints xᵢ₋₁ and xᵢ, where xᵢ₋₁ = (i - 1)Δx and xᵢ = iΔx.For each subinterval, we construct a rectangle with height f(xᵢ) and width Δx, whose area is given by ΔAᵢ = f(xᵢ)Δx. Using right endpoints, we have that f(xᵢ) = f(i/n). Therefore, the area of the entire region S can be approximated by the sum of the areas of these rectangles, given by

Rn = f(Δx)Δx + f(2Δx)Δx + f(3Δx)Δx + ... + f(nΔx)Δx = ∑ᵢ₌₁ⁿf(i/n)Δx.

We can express this sum in sigma notation as

Rn = Σᵢ₌₁ⁿf(i/n)Δx.To find the exact area, we take the limit of this sum as the number of rectangles approaches infinity, or equivalently, as the width of the rectangles approaches zero, which gives us

A = lim Rn = lim Σᵢ₌₁ⁿf(i/n)Δx n→∞ n→∞

By the definition given, we can write this as

A = lim Σᵢ₌₁ⁿf(xᵢ)Δx n→∞This is the area formula using right endpoints. Now, we can apply this formula to the function y = x³ over the interval [0, 1].

We need to use the formula A = lim Σᵢ₌₁ⁿf(xᵢ)Δx to find the area under the curve y = x³ from 0 to 1.

Using right endpoints, we divide the interval [0, 1] into n equal subintervals of width Δx = 1 / n. The ith subinterval has endpoints xᵢ₋₁ = (i - 1)Δx and xᵢ = iΔx. We construct a rectangle with height f(xᵢ) = f(i/n) and width Δx for each subinterval.For the function y = x³, we have f(x) = x³. Therefore, f(i/n) = (i/n)³, and the area formula becomes

A = lim Σᵢ₌₁ⁿf(i/n)Δx= lim Σᵢ₌₁ⁿ[(i/n)³](1/n)= lim Σᵢ₌₁ⁿi³/n⁴

Taking the limit as n approaches infinity gives usA = ∫₀¹ x³ dxWe can evaluate this integral using the power rule of integration to getA = [x⁴/4]₀¹ = 1/4

Therefore, the area under the curve y = x³ from 0 to 1 is 1/4

We used the definition of the area formula with right endpoints to find the area under the curve y = x³ from 0 to 1. We divided the interval [0, 1] into n equal subintervals of width Δx, and used right endpoints to construct rectangles with height f(i/n) = (i/n)³ and width Δx = 1/n. We then took the limit of the sum of these areas as the number of rectangles approached infinity to find the exact area. Applying this formula to the function y = x³ over the interval [0, 1], we found that the area is 1/4.

Step-by-step explanation:

The TV cost without VAT is €479.04.

To calculate the cost of the TV without VAT, we need to remove the VAT amount from the total cost.

First, let's determine the VAT amount. Given that the TV price with VAT is €598.80 and the VAT rate is 20%, we can calculate the VAT amount as follows:

VAT amount = Total cost * (VAT rate / 100)

= €598.80 * (20 / 100)

= €119.76

To find the cost of the TV without VAT, we subtract the VAT amount from the total cost:

Cost without VAT = Total cost - VAT amount

= €598.80 - €119.76

= €479.04

It's important to note that VAT is typically added to the price of goods and services, and to find the cost without VAT, we subtract the VAT amount. The VAT rate is expressed as a percentage and is applied to the total cost to determine the VAT amount. By subtracting the VAT amount from the total cost, we obtain the cost of the TV without including the VAT.

Answer:To calculate the percent increase in Jonathan's hourly wage, we can use the following formula:

Step-by-step explanation:

Percent Increase = ((New Value - Old Value) / Old Value) * 100

Let's plug in the values:

Old Value (hourly wage) = $7.50

New Value (hourly wage) = $8.25

Percent Increase = (($8.25 - $7.50) / $7.50) * 100

Simplifying the calculation:

Percent Increase = ($0.75 / $7.50) * 100

Percent Increase = 0.10 * 100

Percent Increase = 10%

Therefore, Jonathan's hourly wage increased by 10%.

Answer:

The average daily pay of 14 employees is $ [tex]70\frac{6}{7}[/tex]

Step-by-step explanation:

If there is a set of data with n terms, then the average is the sum of their values divided by n

Average = sum of values of the n terms ÷ n

Let us solve the question using this rule

∵ Two employees earn daily $160 each

∴ Their total earn = 2 × 160 = 320

∴ Their total earn a day = $320

∵ Twelve employees earn daily $56 each

∴ Their total earn = 12 × 56 = 672

∴ Their total earn a day = $672

To find the average of the 14 employees, find their total earns and divide it by their number

∵ The total earn of 14 employees = 320 + 672 = 992

∵ They are 14 employees

∴ Their daily average = 992 ÷ 14 = [tex]70\frac{6}{7}[/tex]

∴ The average daily pay of 14 employees is $[tex]70\frac{6}{7}[/tex]

The probability of event B occurring given that event A has already occurred is 0.84. The probability of event A occurring is 0.49. Therefore, the probability of both events B and A occurring is **0.412**, rounded to three decimal places.

The probability of event B occurring given that event A has already occurred is denoted by P(B|A). In this case, P(B|A) = 0.84. This means that if event A occurs, there is an 84% chance that event B will also occur.

The probability of event A occurring is denoted by P(A). In this case, P(A) = 0.49. This means that there is a 49% chance that event A will occur.

The probability of both events B and A occurring is calculated using the following formula:

```

P(B AND A) = P(B|A) * P(A)

```

Substituting the values we have, we get:

```

P(B AND A) = 0.84 * 0.49 = 0.412

```

Therefore, the probability of both events B and A occurring is **0.412**, rounded to three decimal places.

Answer:

The height of the ball is the same after 1.5 seconds and 3.5 seconds. ⇒ (A)

Step-by-step explanation:

The quadratic function is represented by a parabola

∵ The quadratic function modeling the height of a ball over time

∴ f(t) = at² + bt + c

→ t is the time in second, f(t) is the height of the ball after t seconds

∵ It is symmetric about the line t = 2.5

∴ The x-coordinate of its vertex is 2.5

→ That means the average of the x-coordinates of any two

   opposite points belong to f(t) is 2.5

∵ The average of 1.5 and 3.5 = [tex]\frac{1.5+3.5}{2}=\frac{5}{2}=2.5[/tex]

∴ 1.5 and 3.5 have the same value of f(t)

∴ 1.5 and 3.5 have the same height

The height of the ball is the same after 1.5 seconds and 3.5 seconds.

Step-by-step explanation:

You are told that the line segment MO has a total length of 20.

You are also told that point N is somewhere on that line between M and O.  They tell you that the distance from point N to point O is 6.  So to find the distance from point N to point M, you just subtract the length of N to O from the total length of the M to O segment.

                                                                           N to O = 6                                                

<-----M---------------------------------------------------N--------------------O------------------>

                                                    M to O = 20

So if M to O = 20 and you subtract the distance of N to O (6), you will get the distance from M to N.

Step-by-step explanation:

x(x+5)+6(x+5)=(x+5)

Distribute

x^2 + 5x + 6x + 30 = x + 5

Combine

x^2 + 11x + 30 = x + 5

Subtract 1x from both sides

x^2 + 10x + 30 = 5

Subtract 30 from both sides

12x = -25

Divide 12 on both sides

The dimensions of the largest rectangular building that can be constructed on the triangular corner lot, with one side coincident with the longest side of the lot, are 15 m x 15 m.

To find the dimensions of the largest rectangular building, we need to consider the given triangular corner lot. The longest side of the lot is 40 m, and the perpendicular sides are 30 m and 40 m.

Since the rectangular building's side must be coincident with the longest side of the lot, one side of the rectangle will be 40 m. Now, we need to determine the other side to maximize the area.

To maximize the area, we need to make the rectangle as square as possible. This means the other side should be equal to the shorter perpendicular side of the lot, which is 30 m.

Thus, the dimensions of the largest rectangular building that can be constructed on the lot with one side coincident with the longest side of the lot are 40 m x 30 m, which can be simplified to 15 m x 15 m.

When the cloud coverage was 4 percent or less, Glen Sarin took approximately 45 photographs.

Glen Sarin, the photographer, wonders if there is a correlation between the percentage of cloud cover and the number of photographs she captures. She maintains a record that is depicted in the scatterplot below.

When the cloud coverage was 4 percent or less, how many photographs did she take?We can observe that, as the percentage of cloud cover increases, the number of photographs taken by Glen Sarin decreases. As per the scatterplot,  

This can be done by reading the point where the 4% line of cloud cover intersects with the line of best fit and drawing a line perpendicular to the x-axis to see what is the corresponding y-value (which represents the number of photographs)

This can be interpreted as follows: the scatterplot shows a negative correlation between the percentage of cloud cover and the number of photographs taken.

This indicates that as the percentage of cloud cover increases, the number of photographs taken decreases. Glen Sarin may use this information to make informed decisions about when and where to photograph.

Answer:

10=40

50=30

Step-by-step explanation:

Suppose the number of 10 paise coins =x

∴ the number of 50 paise coins =70−x

Now, value of 10 paise coins = Rs.  

10 x  and value of 50 paise coins = Rs.   2 70−x

Total value of coins =   10 x +  2 70−x

​∴  10 x  +  2 70−x  =19

Multiplying both sides by 10, (LCM of 10,2=10), we get  

x+5(70−x)=19×10    

x+350−5x=190

−4x=−160

−4 −4x  =  −4 −160

​∴x=40

∴ number of 10 paise coins =40  

Number of 50 paise coins =70−40=30.
