Answer:

The missing number in the sequence is 73155.

Step-by-step explanation:

To solve this question, we have to find patterns in the numbers.

The number 16351 was generated from a pattern in the number 88511. What pattern?

8 + 8 = 16

So adding the first two digits of the first number, we get the first two digits of the second number

8 - 5 = 3

Subtracting the second and the third digit of the first number, we get the third digit of the second number.

5*1 = 5

Multiplying the third and the fourth digit of the first number, we get the fourth digit of the second number.

1/1 = 1

Dividing the fourth and the fifth digit of the first number, we get the fifth digit of the second number.

Third number

Just like we applied the patterns on the first number to get the second, we can apply the patterns on the second to get the third. So

1 + 6 = 7

6 - 3 = 3

3*5 = 15

5/1 = 5

So

The missing number is 73155.

Confirmation: Third and fourth number:

7 + 3 = 10

3 - 1 = 2

1 * 5 = 5

5/5 = 1

Which shows that the third number is, in fact, 73155

Answer:

To find the fraction of games won, you need to convert the decimal 0.444... to a fraction. One way to do this is to subtract the decimal from 1 and find the repeating decimal's reciprocal.

The power of ten to multiply by depends on the number of decimal places in the repeating decimal, which in this case is an infinite number of 4's. To determine this, you can use the fact that 0.444... is equal to 4/9.

When converting a repeating decimal to a fraction, you need to determine the number of repeating decimal places and then multiply both the numerator and denominator by 10 raised to that power. In the case of 0.444..., there is an infinite number of 4's after the decimal point, so we multiply both the numerator (4) and denominator (9) by an infinite power of 10.

In practice, it's often sufficient to multiply by a high enough power of 10 such that the repeating decimal part becomes a whole number in the numerator and the fraction is reduced to its simplest form.

The additional number of minutes that it takes Minnie to complete the ride than it takes Penny would be 65 minutes.

To determine the additional time that it takes Minnie to complete the ride than it takes Penny we would have to calculate the total time taken by each individual. For Minnie, the time is as follows;

Uphill from town A to B = distance/speed = 10/5 = 2hrs

Downhill from town B to C = 15/30 = 0.5 hrs

Flat road movement from town C to A = 20/20 = 1 hr

Total time = 3.5 hrs

For Penny, the time spent is as follows:

Flat road from town A to C = 20/30 = 0.67 hrs

Uphill from town C to B = 15/10 = 1.5 hrs

Downhill from B to A = 10/40 = 0.25 hrs

Total time = 2.42 hrs

The difference in time between the individuals

= 3.5 hrs - 2.42 hrs

= 1.08 hrs

To solve the differential equation y(4) - 4y" + 4y = 0, we made the substitution z = y" and reduced the order of the equation. After solving for z, we substituted back to solve for y, yielding the general solution y(t) = (c1/4) e^(2t) + (c2/3) t^3 e^(2t) + C1t + C2.

The given differential equation is y(4) - 4y" + 4y = 0, where y(4) represents the fourth derivative of y with respect to the independent variable.

To solve this differential equation, we can make a substitution of the form z = y", which is a common technique used to reduce the order of a differential equation. Taking the second derivative of z with respect to the independent variable, we get:

z' = y"' and z" = y(4)

Substituting these into the original differential equation, we get:

z" - 4z' + 4y = 0

This is a second-order differential equation in z, which we can solve using the characteristic equation method. The characteristic equation is:

r^2 - 4r + 4 = 0

Solving for the roots of this equation, we get:

r = 2 (multiplicity 2)

Therefore, the general solution to the differential equation in z is:

z(t) = c1e^(2t) + c2te^(2t)

where c1 and c2 are constants to be determined based on the initial conditions.

Now, we can substitute back into our original substitution of z = y" to get:

y" = z(t) = c1e^(2t) + c2te^(2t)

Integrating with respect to t once, we get:

y'(t) = c1/2 e^(2t) + c2te^(2t) + C1

where C1 is a constant of integration.

Integrating again, we get:

y(t) = (c1/4) e^(2t) + (c2/3) t^3 e^(2t) + C1t + C2

where C2 is another constant of integration.

Therefore, the general solution to the given differential equation is:

y(t) = (c1/4) e^(2t) + (c2/3) t^3 e^(2t) + C1t + C2

where c1, c2, C1, and C2 are constants to be determined based on the initial conditions.

Answer:

Answer:

\(y=-\frac{1}{4}x - \frac{2}{3}\)

Step-by-step explanation:

Hi there!

We are given the equation 3x + 12y = -8 and we want to convert it into slope-intercept form

The equation is currently in standard form, which is ax+by=c, where a, b, and c are free integer coefficients

Slope-intercept form is y=mx+b, where m is the slope and b is the y intercept

Notice that in standard form, the terms containing x and y are both on the same side, but in slope-intercept form, the expression is set equal to y (x is on the other side)

So first, we'll need to subtract 3x from both sides to remove it from the left side.

3x + 12y = -8

-3x            -3x

_______________

12y=-3x-8

Now divide both sides by 12, since we want to isolate y by itself (it's a bit like solving the equation for y)

12y=-3x-8

÷12   ÷12

___________

y=-3/12x -8/12

We can simplify the fractions to get:

\(y=-\frac{1}{4}x - \frac{2}{3}\)

This is our final answer.

Linear function : y = x + 4

Exponential function : y = 4.5 e^(0.144 x)

Power function : y = 4.5 x^0.415

Answer:

Step-by-step explanation:

If cost price (CP) is greater than selling price (SP) , then the item is sold for loss.

Loss = CP - SP

Loss% = \(\frac{loss}{CP}*100\)

If SP is greater than Cp, then the item is sold for a profit.

Profit =SP -CP

Gain % = \(\frac{gain}{CP}*100\)

a)  CP = $50    ; SP = $30   ; CP > SP,  loss

Loss = 50 - 30 = $ 20

Loss % = \(\frac{20}{50}*100=20*2\)

            = 40% loss

b) CP = £ 5000 ; SP = £6250  ; SP > CP ,  Profit

Profit = 6250 - 5000 = £ 1250

Profit % = \(\frac{1250}{5000}*100=25\)
