What’s the value of p?

Mathematics

Answer:

p = 10

Step-by-step explanation:

Given

x³(x-y)^{9} - y³(x-y)^{9} ← factor out (x-y)^{9} from each term

= (x-y)^{9} (x³ - y³ )

x³ - y³ ← is a difference of cubes and factors as

(x - y)(x² + xy + y² )

Thus expression can now be written

= (x-9)^{9} (x - 9)(x² + xy + y²)

= x-y)^{10} (x² + y² + xy)

with the exponent of (x-y)^{p} being p = 10

Answer:

In statistical hypothesis testing, the p-value or probability value is, for a given statistical model, the probability that, when the null hypothesis is true, the statistical summary (such as the absolute value of the sample mean difference between two compared groups) would be greater than or equal to the actual

If break starts at 2:45pm this friday, the 26th, and we are back at 7:45am april 5, how many hours of vacation do we get? (add y
Black_prince [1.1K]

Answer: 9 days + 17 hours

Step-by-step explanation:

Lets calculate the hours first. Because the minutes are the same lets just calculate hours.

12-2=10

Now we add the morning hours.

7+10=17

Now all we have to do is add the days. We also have to keep in mind that this Friday is the 26th. It would also be 5 days until the month ends.

Because we already calculated the rest of the day of the 26th and 5th of April we won't include those as days.

5+4=9 days.

I added the five days until March ended and the 4 days of april. We aren't adding the 5th day of April since we already calculated the hours.

9 days + 17 hours

Mad math for pi, I have no clue how to do this!!
bogdanovich [222]

To calculate the volume of this figure, we just have to find the volume of the hemisphere and the volume of the cone, then sum them up.

The volume of a hemisphere (the half of a sphere) is given by the formula:

V=\frac{2}{3}\pi r^3

Where r is the radius.

The volume of a cone is given by the formula:

V=\frac{1}{3}\pi r^2h

Where h is the height of the cone.

From the figure we have:

r = 5.3in

h = 9 in

Then, when we substitute these values into the above formulas, we get:

For the hemisphere:

V=\frac{2}{3}\pi r^3=\frac{2}{3}\times3.14\times(5.3)^3=311.6

The volume of the hemisphere is 311.6in^3

For the cone:

V=\frac{1}{3}\pi r^2h=\frac{1}{3}\times3.14\times5.3^2\times9=264.7

As mentioned, the volume of the whole figure is the sum of the volume of the cone and the volume of the hemisphere, then, the volume of the figure is:

V=311.6in^3 + 264.7in^3 = 576.3in^3

Then, the correct answer is option A
