Answer: 168,750 chocolates

Step-by-step explanation:

If there are 90 chocolates in a box and there are 1,875 boxes, you multiply 1,875 by 90 to get the total number of chocolates needed to complete the order.

1,875 * 90 = 168,750

There are 168,750 chocolates needed to complete the order.

The volumes of the solids formed by revolving the given region about the specified lines are as follows:

a) Volume = π∫[a,b] (16 – x^2)^2 dx, where a = -5 and b = 0.

b) Volume = π∫[a,b] (32 – y)^2 dy, where a = 0 and b = 16.

c) Volume = π∫[a,b] (8^2 – x)^2 dx, where a = 0 and b = 16.

a) To find the volume when revolving about y = -5, we integrate the squared equation of the given region (y = 16 – x^2) with respect to x from -5 to 0.

b) When revolving about y = 32, we integrate the squared equation (y = 16 – x^2) with respect to y from 0 to 16.

c) Finally, when revolving about x = 8, we integrate the squared equation (y = 16 – x^2) with respect to x from 0 to 16.

Answer:

wish you bad luck you dummy

The computation of the equation shows that the answers will be:

12. 340 units

13. 2(270) + (2 × x) = 690

14. x = 5

12. The first equation that's given will be:

(13.50 × x) - (3.65 × x) = 3349

13.50x - 3.65x = 3349

9.85x = 3349

x = 3349/9.85

x = 340

The number to break even is 340 units

13. The equation that can be used to find the perimeter will be:

2(270) + (2 × x) = 690

540 + 2x = 690

2x = 690 - 540

2x = 150

x = 150/2 = 75

14. x + x + 2 + 8 = 20

2x + 10 = 20

2x = 20 - 10

2x = 10

x = 10/2

x = 5

Cam will have approximately $18,034.48 in his savings account when he finishes his studies.

Explanation:

Cam saved $270 per month for three years while working. Considering that money is worth 4.8% compounded monthly, we can calculate the total amount he will have in his savings account when he finishes his studies.

To find the future value, we can use the formula for compound interest:

FV = PV * (1 + r)^n

Where:

FV is the future value

PV is the present value

r is the interest rate per compounding period

n is the number of compounding periods

In this case, Cam saved $270 per month for three years, which gives us a present value (PV) of $9,720. The interest rate (r) is 4.8% divided by 12 to get the monthly interest rate of 0.4%, and the number of compounding periods (n) is 5 years multiplied by 12 months, which equals 60.

Plugging these values into the formula, we get:

FV = $9,720 * (1 + 0.004)^60

≈ $18,034.48

Therefore, Cam will have approximately $18,034.48 in his savings account when he finishes his studies.

Answer:

2(x-3)² - 11 where a = 2, b = -3, c = -11

Step-by-step explanation:

Taking the first 2 terms,

2x² - 12x ==> 2(x² -6x)   [1]

x² -6x can be rewritten as (x -3)² - 9 [2]

since (x-3)² = x² -6x + 9  

Substituting for x² -6x in [1] we get

2(x² -6x) = 2((x -3)² - 9 ) = 2(x-3)² -18

Therefore substituting for 2x² - 12x in the original equation we get

2x² - 12x + 7 = 2(x-3)² -18 + 7 ==> 2(x-3)² -11

this is in the form (a(x+b) + c where a = 2, b = -3 and c= -11

Cross-check
2(x-3)² - 11 ==> 2 (x² -6x +9) -11 ==> 2x² -12x +18 - 11 ==> 2x² -12x + 7

Answer:

16 rows

Step-by-step explanation

48x10=480, then divide 480 by 30. 480÷30=16. So, there will be 16 rows.

The number of litres (Volume) of oil that is present in the tank of given dimension is calculated to be 806 litres (approximately).

The volume of any cylinder can be calculated using the formula,

V = πr²h

(Here V is the volume, r is the radius of the base, and h is the height of the cylinder)

As, the cylinder is one-fifth full of oil, which means that it is four-fifths empty. Therefore, the volume of oil in the tank is:

Volume of oil = (1/5) x Total Volume

Substituting the given values, we have:

Total Volume =  π(80cm)²(200cm) = 4,031,240 cm³

Volume of oil = (1/5) x 4,031,240 cm³ = 806,248 cm³

Converting cm³ to litres, we have:

1 litre = 1000 cm³

Volume of oil = 806,248 cm³ ÷ 1000 = 806.248 litres

Therefore, after rounding of the final volume (806.248 litres) to the nearest litre, the final answer is found to be 806 litres of oil.

The constant of proportionality is 9.2

Total train cars = 20

Total wheels = 184

The constant of proportionality represents the relationship between two directly proportional quantities. In this case, the constant of proportionality represents the relationship between the number of train cars and the number of wheels.

Y = kx can be used to describe the relationship between two variables when they are directly or indirectly proportional to one another. To find the constant of proportionality in this situation, it is required to divide the number of train cars by the number of wheels.

Using the formula -

If the number of wheels (w) ∝ Number of train cars (t)

w = kt

Where k is the proportionality constant

Thus,

k = w/t

The required equation of the parabola in the vertex form is \(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)

A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line is called a parabola.

Given that, a parabola has the directrix x=6 and the focus (3,-5), we need to find the equation of the parabola,

The standard form of a left-right parabola is given as:

4p(x-h) = (y-k)²

Focus = (p+h, k)

Therefore,

h+p = 3....(i)

Directrix =

x = h-p

h-p = 6...(ii)

Solving the equations we get,

h = 9/2

p = -3/2

Substitute into the standard form:

4p(x-h) = (y-k)²

4(-3/2)(x-9/2) = (y+5)²

-6(x-9/2) = (y+5)²

\(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)

Hence, the required equation of the parabola in the vertex form is \(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)

c=1/2  which makes fx|y (x, y) a valid conditional probability mass function.

What is conditional probability?

The possibility of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability. It is determined by multiplying the likelihood of the earlier event by the increased likelihood of the later, or conditional, event.

Given that;

p(x) = \(c (\frac{2}{3} )^n\)   where x = 1,2,3,........

for getting value of c we are using the expression :

\(\sum_{n=1}^{\infty} c(\frac{2}{3})^n = 1\)

\(c\sum_{n=1}^{\infty} (\frac{2}{3})^n = 1\)

Since we want p(x) to be a Probability Mass Function, your approach is correct, since for any such function

fX:A→[0,1],X:S→A⊆R, it is :

\(\sum _{x\in A} \ fX(x)=1\)

As long as you've correctly understood that condition, you can proceed with your specific exercise as follows:

\(\sum_{n=1}^{\infty} c(\frac{2}{3})^n = 1\)

⇔ \(c\sum_{n=1}^{\infty} (\frac{2}{3})^n = 1\)

⇔2c = 1

⇔c = 1/2

Hence c =  1/2 is the valid conditional probability mass function.
