the appropriate z-factor to use when deriving a slope surface with the given horizontal and vertical units and resolutions is 0.1.

When deriving a slope surface, the z-factor represents the conversion factor from the vertical units to the horizontal units. In this case, the horizontal units are in feet with a horizontal resolution of 10, and the vertical units are also in feet but with a vertical resolution of 1. To calculate the appropriate z-factor for deriving a slope surface, we need to determine the ratio of the vertical to horizontal units.

The z-factor can be calculated as follows:

z-factor = vertical units / horizontal units

= 1 / 10

= 0.1

the final equivalent expression is 2(a - 1) / 3a2 for the expression 3a2-6a/3a3 can be simplified by factoring out the greatest common factor in the numerator and denominator.

The greatest common factor of the numerator is 3a, which can be factored out as follows:

3a(2a - 2) / 3a(3a2)

The 3a in the numerator and denominator cancel out, leaving:

2a - 2 / 3a2

Therefore, the expression is equivalent to (2a - 2) / (3a2).

This expression can be further simplified by factoring out a 2 in the numerator:

2(a - 1) / 3a2

So, the final equivalent expression is 2(a - 1) / 3a2.

In summary, the expression 3a2-6a/3a3 simplifies to 2(a - 1) / 3a2, which is the same as 2a - 2 / 3a2 after factoring out the greatest common factor. It is important to note that we assume the denominator does not equal zero because division by zero is undefined and not a valid mathematical operation.

Answer:

45 feet

Step-by-step explanation:

if 1 cm = 3 ft, we can scale up the drawing from there.

We are multiplying each cm by 3, and considering that length to be 3 feet.

If we had 2 cm, (multiply both by 3) we would have 6 feet.

So, if we had 15 cm, we also need to convert this scale length into actual length. We do this by multiplying

15 × 3 = 45

So, we know that the actual length of the playground in feet is 45 feet.

After using the concept of combinations, John can bring 10 different combinations of fruit to school.

To determine the number of combinations of fruit that John can bring to school, we need to calculate the number of ways he can choose 2 fruits from the given options. This can be done using the concept of combinations.

The formula for calculating combinations is:

C(n, r) = n! / (r! * (n - r)!)

Where n is the total number of items (fruits) and r is the number of items (fruits) to be chosen.

In this case, John has 5 fruits (n = 5) and he wants to bring 2 fruits (r = 2) to school.

Using the formula, we can calculate:

C(5, 2) = 5! / (2! * (5 - 2)!)

= 5! / (2! * 3!)

= (5 * 4 * 3!) / (2! * 3!)

= (5 * 4) / 2

= 10

Therefore, John can bring 10 different combinations of fruit to school.

The weighted moving average formula with weights of 0.3 and 0.7 can be calculated using the AVERAGE and SUMPRODUCT functions in Excel. This formula can be used to calculate forecasted values for a range of years.

To use a 2-year weighted moving average to calculate forecasts for the years 1992-2002 with the weight of 0.7 assigned to the most recent year data, we can use the SUMPRODUCT function.
First, we need to create a table that includes the years 1990-2002 and their corresponding data points. Then, we can use the following formula to calculate the weighted moving average:
=(0.3*AVERAGE(B2:B3))+(0.7*B3)
This formula calculates the weighted moving average for each year by taking 30% of the average of the data for the previous two years (B2:B3) and 70% of the data for the most recent year (B3). We can then drag the formula down to calculate the forecasted values for the remaining years.
The SUMPRODUCT function can be used to simplify this calculation. The formula for the weighted moving average using SUMPRODUCT would be:
=SUMPRODUCT(B3:B4,{0.3,0.7})
This formula multiplies the data for the previous two years (B3:B4) by their respective weights (0.3 and 0.7) and then sums the products to calculate the weighted moving average for the most recent year. We can then drag the formula down to calculate the forecasted values for the remaining years.
In summary, the weighted moving average formula with weights of 0.3 and 0.7 can be calculated using the AVERAGE and SUMPRODUCT functions in Excel. This formula can be used to calculate forecasted values for a range of years.

Answer:

The answer is 70

Step-by-step explanation:

5 x 5 = 25

14 x 5 = 70

Hope this helps

1. Let the four consecutive numbers be x, x+1, x+2, x+3

The sum of four consecutive number is already given to us = 70

Therefore

⇒(x)+(x+1)+(x+2)+(x+3)=70  

We need to combine x as we have four x terms in the equation. The next step is to get all of the x’s on one side of the equation and all the numbers on the other side. The same rule applies – whatever you do to one side of the equation, you must do to the other side as well!

⇒4x+6=70⇒4x=64⇒x=16

So, the four numbers are 16, 17, 18 and 19.

Hence, the greatest number among them is 19.

The answer is:

5/4

Work/explanation:

Let's work out the slope of the line.

The equation is in y = mx + b form where m = slope; b = y intercept.

Similarly, in y=5/4x - 7/4, the slope is 5/4.

Lucy has $7 less than Kristine and $5 more than Nina together, the three have $35. Lucy has $11.

Let's denote the amount of money that Kristine has as K, the amount of money that Lucy has as L, and the amount of money that Nina has as N.

According to the given information, we can form two equations:

Lucy has $7 less than Kristine: L = K - 7

Lucy has $5 more than Nina: L = N + 5

We also know that the three of them have a total of $35: K + L + N = 35

We can solve this system of equations to find the values of K, L, and N.

Substituting equation 1 into equation 3, we get:

K + (K - 7) + N = 35

2K - 7 + N = 35

Substituting equation 2 into the above equation, we get:

2K - 7 + (L - 5) = 35

2K + L - 12 = 35

Since Lucy has $7 less than Kristine (equation 1), we can substitute K - 7 for L in the above equation:

2K + (K - 7) - 12 = 35

3K - 19 = 35

Adding 19 to both sides:

3K = 54

Dividing both sides by 3:

K = 18

Now we can substitute the value of K into equation 1 to find L:

L = K - 7

L = 18 - 7

L = 11

Finally, we can find the value of N by substituting the values of K and L into equation 3:

K + L + N = 35

18 + 11 + N = 35

N = 35 - 18 - 11

N = 6

Therefore, Lucy has $11.

Area of the region inside the circle r=4cos(theta) and outside the circle r=2 is 4π/3 + 2√3

A form created using the polar coordinate system is called a polar curve. Points on polar curves have varying distances from the origin (the pole), depending on the angle taken off the positive x-axis to calculate distance. Both well-known Cartesian shapes like ellipses and some less well-known shapes like cardioids and lemniscates can be described by polar curves.

r = 1 − cosθsin3θ

Polar curves are more useful for describing paths that are an absolute distance from a certain point than Cartesian curves, which are good for describing paths in terms of horizontal and vertical lengths. Polar curves can be used to explain directional microphone pickup patterns, which is a useful application. Depending on where the sound is coming from outside the microphone, a directional microphone will take up sounds with varied tonal characteristics. A cardioid microphone, for instance, has a pickup pattern like a cardioid.

The area between two polar curves can be found by subtracting the area inside the inner curve away from the area inside the outer curve.

The figure attached shows the bounded region of the two graphs. The red curve is  r=4cos⁡(θ) and the blue curve is r=2.

The points of intersection of the two curves are

θ = π/3 and 5π/3

The area is calculated as follows:

Since the bounded region is symmetric about the horizontal axis, we will find the area of the top region, and then multiply by 2, so as to get the total area.

A = 2 \(\(\int_{0}^{\pi /3}\) ½ (4 cos (θ)² − ½ (2)² dθ

  =  \(\(\int_{0}^{\pi /3}\) 16 cos2 (θ) − 4dθ

  = \(\(\int_{0}^{\pi /3}\) 8 (1+cos(2θ)) − 4dθ

  =\(\(\int_{0}^{\pi /3}\) 4 + 8 cos (2θ) dθ

  = [4θ + 4sin (2θ)] \(\(\int_{0}^{\pi /3}\)

y(1) will be the median of a(2), 2, and r(0), and its specific value cannot be determined without more information about a(2) and r(0).

To find the response y(1) for the given system, we need to substitute the input signal x(n) into the system equation and evaluate it at n = 1.

Given that the input signal x(n) is defined as 0 for n ≤ 4 and 10 elsewhere, we can deduce the following values for the system equation at n = 1:

a(n+1) = a(2) (as n+1 = 2 for n = 1) r(n-1) = r(0) (as n-1 = 0 for n = 1)

Now, we need to evaluate the median of the three terms in the system equation:

y(1) = median{a(2), 2, r(0)}

Since we don't have any specific information about the values of a(2) and r(0), we cannot determine their exact values. However, we can say that the median of any three numbers will be the middle value when they are arranged in ascending order.

Therefore, y(1) will be the median of a(2), 2, and r(0), and its specific value cannot be determined without more information about a(2) and r(0).
