The original price of the novel is $21.5

The first step is to write out the parameters given in the question

Last year, Gloria buys a novel for $18.70

This price is with a discount of 15% form the original price

The original price of the novel can be calculated as follows

15/100 × 18.70

= 0.15 × 18.70

= 2.805

The next step is to add 2.805 to the price of the novel last year($18.70)

We know that the measure of AB is 240°.

Given that AC is a diameter of D and MBDC = 150°, we know that angle ABC is a right angle (90°) because it is inscribed in a semicircle.

Using the fact that the sum of angles in a triangle is 180°, we can find angle MBC:

MBC + 150° + 90° = 180°
MBC  = -60°

Since angle MBC is negative, we know that it must actually be 360° - 60° = 300°.

Finally, using the fact that angles on a straight line add up to 180°, we can find angle ABM:

ABM + MBC = 180°
ABM + 300° = 180°
ABM = -120°

Again, since angle ABM  is negative, we know that it must actually be 360° - 120° = 240°.

Therefore, the measure of AB is 240°.

To show that the series Σα) f(n)/2n^3 - 1 n converges regardless of the rule for f, we can use the Comparison Test. Let's choose a series that is easier to compare to, such as Σ(1/2n^3).

First, note that 0 ≤ f(n) ≤ 1 for all n, since f is a function that is not negative and bounded by 1. Thus, we have: 0 ≤ f(n)/2n^3 - 1 n ≤ 1/2n^3, Now, we can compare the given series to the series Σ(1/2n^3) using the Comparison Test. Since 0 ≤ f(n)/2n^3 - 1 n ≤ 1/2n^3 for all n, we know that: 0 ≤ Σα) f(n)/2n^3 - 1 n ≤ Σ(1/2n^3), The series Σ(1/2n^3) is a convergent p-series with p = 3 > 1, so by the Comparison Test, the given series Σα) f(n)/2n^3 - 1 n also converges.

Adding 12 apples to a basket initially containing c apples results in a total of 13.50 apples.

How can a real-world situation be represented by the equation 12 + c = 13.50?

The equation 12 + c = 13.50 can represent a real-world situation of purchasing items at a store and calculating the total cost. In this scenario, let's assume that 12 represents the price of a particular item, and c represents the additional cost, such as taxes or fees.

The equation states that when the additional cost is added to the base price of 12, the total cost becomes 13.50. This can occur when there is a sales tax or an additional charge applied to the base price. By solving the equation for c, we find that the additional cost is 1.50.

Therefore, in this situation, the real-world interpretation is that the item costs 12 dollars, and the additional cost, such as taxes, is 1.50 dollars, resulting in a total cost of 13.50 dollars.

You should always measure your following distance in seconds. The correct answer for measuring following distance is A.  

It is important to keep a safe distance between vehicles on the road, which is known as following distance. Measuring following distance in seconds is a more reliable method than measuring it in car lengths or feet.

The recommended following distance is typically two to three seconds. This means that when the vehicle in front of you passes a fixed point on the road, you should not reach that same point before two to three seconds have elapsed.

Measuring in seconds is more effective as it takes into account the speed at which both vehicles are traveling. If you measure in car lengths or feet, it may not be accurate as the length of the cars may differ, and it does not account for the speed of the vehicles. By measuring in seconds, you can maintain a safe distance and reduce the risk of accidents or collisions.

The height of the statue is 288 feet.

The scale factor is 240:1

Or, the ratio of the height of the statue to the height of the drawing = 240:1.

This means, for 1 unit height of drawing, the height of the statue = 240 units

Or, for 1 feet height of the drawing, the height of the statue = 240 feet.

Let us suppose the actual height of the statue to be x.

The height of the drawing = 1.2 feet    (given)

So, the ratio of the height of the statue to the height of the drawing = x/1.2

But, the scale factor  = 240:1 = 240/1

∴ 240/1=x/1.2

⇒x=240×1.2

⇒x=288

Hence, the height of the statue is 288 feet.

To evaluate the integral ∫(x^2+10x-9)e^-4x dx using integration by parts, we need to choose two functions to multiply together, one of which we differentiate and the other we integrate. A common choice is to let u = x^2+10x-9 and dv = e^-4x dx, which gives du = (2x+10) dx and v = (-1/4)e^-4x.

Using the formula for integration by parts, we have:

∫(x^2+10x-9)e^-4x dx = uv - ∫v du

= (-1/4)(x^2+10x-9)e^-4x - ∫(-1/4)(2x+10)e^-4x dx

= (-1/4)(x^2+10x-9)e^-4x + (1/2)∫(x+5)e^-4x dx.

Now we can use integration by substitution to evaluate the second integral on the right-hand side:

(1/2)∫(x+5)e^-4x dx = (-1/8)(x+5)e^-4x - (1/32)e^-4x + C,

where C is the constant of integration.

Substituting this back into our previous equation, we get:

∫(x^2+10x-9)e^-4x dx = (-1/4)(x^2+10x-9)e^-4x - (1/8)(x+5)e^-4x - (1/32)e^-4x + C.

Answer:

Sure. Here is the equation for the cost, C, after h hours of babysitting:

```

C = 3 + 5h

```

This equation can be found by combining the flat fee of $3 with the hourly rate of $5. For example, if Nicole babysits for 2 hours, she will make $3 + (2 * $5) = $13.

To find how much Nicole will make after babysitting for 8 hours, we can simply substitute h = 8 into the equation. This gives us:

```

C = 3 + 5(8) = 3 + 40 = $43

```

Therefore, Nicole will make $43 after babysitting for 8 hours.

Answer:c= 3 + 5(8)

Step-by-step explanation:

3 is flat fee, and then plus $5 and hour. you know she's going for 8 hours, so you multiply hourly rate by the number of hours plus flat fee and you get your answer

The original number was 17 to which when Angad adds 20, then doubles it and gets an answer of 53.

To solve this problem, we need to work backwards from the final answer. If Angad added 20 to the original number, we can subtract 20 from 53 to get 33. This means that after Angad doubled the number, he had 33.

To find the original number, we need to undo the doubling process. If Angad had 33 after doubling the number, we can divide 33 by 2 to get the original number.

33 divided by 2 equals 16.5. However, we know that the original number must be a whole number since we cannot add 20 to a decimal. Therefore, we can round up to the nearest whole number to get 17.

So, the original number was 17.

In summary, to find the original number, we worked backwards from the final answer and undid the steps that Angad took. We subtracted 20 to undo the addition, then divided by 2 to undo the doubling. We rounded up to the nearest whole number since the original number must be a whole number.

The length of the minor arc GD is approximately 0.196π units.

To get the length of the minor arc GD, we need to subtract the measure of the major arc mDUG from the circumference of the circle, and then divide by 360° to find the length of one degree of arc.
First, we need to find the circumference of the circle. Since GA = 29, we know that the radius of the circle is also 29. The formula for the circumference of a circle is C = 2πr, so for this circle we have: C = 2π(29) = 58π
Next, we need to subtract the measure of the major arc mDUG from the circumference of the circle. Since mDUG = 185°, we have:
58π - (185/360)(58π) = (175/360)(58π)
Simplifying this expression, we get: (175/360)(58π) = 29(175/72)π ≈ 70.48π
Finally, we divide this value by 360° to find the length of one degree of arc:
(70.48π)/360 ≈ 0.196π
Therefore, the length of the minor arc GD is approximately 0.196π units.

True. In a continuous uniform distribution, all values within a specified interval are equally likely to occur. The mean or expected value of this distribution can be found by taking the average of the upper and lower limits of the interval.

This can be represented mathematically as (a+b)/2, where a and b are the lower and upper limits of the interval. For example, if we have a continuous uniform distribution on the interval [0,10], the mean value would be (0+10)/2 = 5.

This means that on average, we would expect a randomly selected value from this distribution to be around 5. It's important to note that the mean of a continuous uniform distribution is not affected by the shape or spread of the distribution, as all values have an equal chance of occurring.
