The volume of the solid enclosed by the two paraboloids is approximately 1365.34π cubic units.

Here, we have to find the volume of the solid enclosed by the two paraboloids [tex]y = x^2 + z^2[/tex] and [tex]y = 32 - x^2 - z^2[/tex],

we need to set up a triple integral in cylindrical coordinates.

In cylindrical coordinates, we have:

x = r cos(θ)

z = r sin(θ)

y = y

The limits of integration for r, θ, and y will depend on the region of integration.

First, let's find the intersection points of the two paraboloids:

[tex]x^2 + z^2 = 32 - x^2 - z^2\\2x^2 + 2z^2 = 32\\x^2 + z^2 = 16[/tex]

This represents a circular region with radius r = 4 in the x-z plane.

Now, let's find the limits of integration for r, θ, and y:

For r:

Since the circular region has a radius of 4, the limits of r will be from 0 to 4.

0 ≤ r ≤ 4

For θ:

The intersection points form a complete circle in the x-z plane, so the limits of θ will be from 0 to 2π.

0 ≤ θ ≤ 2π

For y:

The lower paraboloid is given by [tex]y = x^2 + z^2[/tex], and the upper paraboloid is given by [tex]y = 32 - x^2 - z^2[/tex].

The limits of y will be from the lower paraboloid to the upper paraboloid.

[tex]x^2 + z^2 \leq y \leq 32 - x^2 - z^2[/tex]

Now, we can set up the triple integral to find the volume V:

V = ∫∫∫ (y) dy dθ dr

V = ∫∫∫ [tex](r^2 cos^2(\theta) + r^2 sin^2(\theta)) dy d\theta dr[/tex]

V = ∫∫∫ [tex](r^2) dy d\theta dr[/tex]

V = ∫∫ [tex](r^2) y|_{(x^2+z^2)}^{(32-x^2-z^2)} d\theta dr[/tex]

V = ∫∫ [tex](r^2) (32 - 2x^2 - 2z^2) d\theta dr[/tex]

V = ∫ [tex](32r^2 - 2r^2(x^2 + z^2)) d\theta dr[/tex]

V = ∫ [tex](32r^2 - 2r^2r^2) d\theta dr[/tex]

V = ∫ [tex](32r^2 - 2r^4) d\theta dr[/tex]

Now, integrate with respect to θ from 0 to 2π:

V = ∫(0 to 2π) ∫(0 to 4) [tex](32r^2 - 2r^4)[/tex] dr dθ

Now, integrate with respect to r from 0 to 4:

V = ∫(0 to 2π) [tex][(32/3)r^3 - (1/3)r^5] |_0 ^4[/tex] dθ

V = ∫(0 to 2π) [tex][(32/3)(4^3) - (1/3)(4^5)][/tex] dθ

V = ∫(0 to 2π) [(32/3)(64) - (1/3)(1024)] dθ

V = ∫(0 to 2π) [682.67] dθ

V = 682.67 * (2π) - 682.67 * (0)

V = 1365.34π cubic units

Therefore, the volume of the solid enclosed by the two paraboloids is approximately 1365.34π cubic units.

The missing side (the adjacent side) is approximately 13.257 units long.

To find the missing side, we can use the cosine function which relates the cosine of an angle to the adjacent side and the hypotenuse of a right triangle.

cos(28°) = adjacent side / hypotenuse

We are given the measure of the angle and the length of one side, so we can plug in those values and solve for the missing side.

cos(28°) = adjacent side / 15

adjacent side = 15 cos(28°)

Using a calculator to evaluate cos(28°) to four decimal places:

cos(28°) ≈ 0.8838

Substituting into the equation:

adjacent side ≈ 15 × 0.8838

There are 34,650 distinct ways to order the letters of "mississippi" subject to the requirement that no two S's are adjacent and no two P's are adjacent.

To find the number of ways to order the letters of the word "mississippi" while satisfying the given conditions, we can use the principle of inclusion-exclusion.

First, we consider all the ways to order the letters without any restrictions. There are 11 letters in "mississippi", so there are 11! ways to order them.

Next, we consider the cases where two S's are adjacent and the cases where two P's are adjacent. To count these cases, we can treat each pair of adjacent S's or P's as a single letter. So we have 10 letters to order in the case of adjacent S's, and 9 letters to order in the case of adjacent P's.

For the case of adjacent S's, we have 10! ways to order the letters. However, we have overcounted the cases where both pairs of S's are adjacent, so we need to subtract those out. There are 9 letters in this case (M, I, S1, S2, I, P, P, I), so there are 9! ways to order them. Therefore, the number of cases where two S's are adjacent is 10! - 9!.

Similarly, for the case of adjacent P's, we have 9! ways to order the letters. But we have overcounted the cases where both pairs of P's are adjacent, so we need to subtract those out. There are 8 letters in this case (M, I, S1, S2, I, P1, P2, I), so there are 8! ways to order them. Therefore, the number of cases where two P's are adjacent is 9! - 8!.

Now we need to add back in the cases where both pairs of S's and both pairs of P's are adjacent, because we subtracted them out twice. There are 8 letters in this case (M, I, S1, S2, P1, P2, I, I), so there are 8! ways to order them. Therefore, the number of cases where both pairs of S's and both pairs of P's are adjacent is 8!.

Finally, we subtract all these cases from the total number of ways to order the letters:

11! - (10! - 9!) - (9! - 8!) + 8! = 34,650

1. The x-intercepts are: x = -1/2 and x = 2

2. The vertex is at (3/4, 19).

3. To graph the function f(x) = -16x² + 24x + 16,

1. Solve for x:

-16x² + 24x + 16 = 0

Dividing both sides by -8, we get:

2x² - 3x - 2 = 0

Using the quadratic formula, we have:

x = [3 ± ✓ (3² - 4(2)(-2))]/(2(2))

x = [3 ±  ✓ (25)]/4

x = [3 ± 5]/4

The x-intercepts are: x = -1/2 and x = 2

2. The vertex of the graph of f(x) can be found by using the formula x = -b/(2a) and plugging it into the function to find the corresponding y-value.

In this case, we have:

x = -24/(2(-16)) = 3/4

f(3/4) = -16(3/4)² + 24(3/4) + 16 = 19

Therefore, the vertex is at (3/4, 19).

3 To graph the function f(x) = -16x² + 24x + 16, you can follow these steps:

Find the vertex of the parabola: The vertex is given by the formula x = -b/2a, where a = -16 and b = 24.

Find the y-intercept: The y-intercept is the value of f(x) when x = 0. Therefore, f(0) = -16(0)² + 24(0) + 16 = 16. The y-intercept is (0, 16).

Find the x-intercepts: The x-intercepts are the values of x for which f(x) = 0. To find them, solve the quadratic equation -16x² + 24x + 16 = 0.

B ≈ 1.03°

C ≈ 76° 27'

We are given angle A = 12° 33' and side c = 283 ft. Let's first find angle C using the sine ratio:

sin C = opposite / hypotenuse

sin C = a / c

a = c * sin C

Using a calculator:

sin C = sin(90° - A) ≈ 0.996

a ≈ 282.95 ft

Therefore, we have side a ≈ 282.95 ft. To find the remaining side b, we can use the Pythagorean theorem:

b² = c² - a²

b² = (283 ft)² - (282.95 ft)²

b ≈ 0.79 ft

(Note that we may have some rounding error in the last digit due to using approximate values for a and c, but it should be insignificant.)

Now let's find the angles:

Angle B = 90° - A ≈ 77° 27'

Using the sine ratio again:

sin B = opposite / hypotenuse

sin B = b / c

B ≈ 1.03°

(Note that we may have some rounding error here due to using an approximate value for b, but it should be insignificant compared to the precision of the given angles.)

Answer:

$21,366.54

Step-by-step explanation:

Assuming that the interest is compounded annually, we can use the formula:

A = P(1 + r/n)^(n*t)

Where:

A = the final amount

P = the initial principal (or amount borrowed)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, P = $18,000, r = 0.045, n = 1 (compounded annually), and t = 4. Plugging in these values, we get:

A = 18000(1 + 0.045/1)^(1*4) = $21,366.54

Let X be the number of heads Max gets and Y be the number of heads Sam gets. Both X and Y follow a binomial distribution with parameters k and 0.5.

We want to find P(Y>X), which can be expressed as:

P(Y>X) = P(Y-X>0)

Let Z = Y - X. Then Z follows a binomial distribution with parameters k and p = 0.5 - 0.5 = 0.

The mean of Z is E(Z) = E(Y-X) = E(Y) - E(X) = k/2 - k/2 = 0.

The variance of Z is Var(Z) = Var(Y-X) = Var(Y) + Var(X) = k/4 + k/4 = k/2.

Using the normal approximation to the binomial distribution, we can approximate Z as a normal distribution with mean 0 and variance k/2, for large enough values of k.

Therefore, P(Y>X) = P(Z>0) can be approximated using the standard normal distribution:

P(Z>0) = P((Z-0)/sqrt(k/2) > (0-0)/sqrt(k/2)) = P(Z/sqrt(k/2) > 0)
