please help im sorry i dont understand shapes and angles

Answer:

first blank: 15

second blank: 90

Step-by-step explanation:

Obviously, sin and cos are related, but they are not the same thing. In order for them to be equal:

sin(____) = cos(75)

the angles have to add up to 90 (complementary)

What + 75 is 90?

Do a tiny calc:

90 - 75 is 15

The second question is stating the rule generically.

x + (90 - x) is 90

The divergence theorem states that the surface integral of the divergence of a vector field over a closed surface is equal to the triple integral of the divergence of the vector field over the volume enclosed by the surface

we are given the vector field F = (11x, 2y, \(z^{2}\)) and the surface S defined by the equation \(x^2 + y^2 + z^2\)= 1, which represents a unit sphere.

To evaluate the surface integral ∬S F · ds using the divergence theorem, we first need to calculate the divergence of the vector field F. The divergence of F, denoted as ∇ · F, is given by the sum of the partial derivatives of the components of F with respect to their corresponding variables. Therefore, ∇ · F = ∂(11x)/∂x + ∂(2y)/∂y + ∂(z^2)/∂z = 11 + 2 + 2z.

Applying the divergence theorem, the surface integral ∬S F · ds is equal to the triple integral ∭V (∇ · F) dV, where V represents the volume enclosed by the surface S.

Since the surface S is a unit sphere centered at the origin, the triple integral ∭V (∇ · F) dV can be evaluated by integrating over the volume of the sphere.

Answer:

x = 9.

Step-by-step explanation:

The first step I did was replace y with 6.

\(2x+3\cdot \:6=36\)

I multiplied 3*6 next.

\(2x+18=36\)

Then I subtracted 18 from both sides of the equation.

\(2x+18-18=36-18\)

After, I simplified the equation.

2x=18

Divided the both by 2 and then simplified again to get...

\(\frac{2x}{2}=\frac{18}{2}\)  

\(x=9\)

So \(x=9\).

The difference in the proportion of males and the proportion of females that smoke is 0.08

In a sample of 61 males, 15 smoke, while in a sample of 48 females, 8 smoke.

The given parameters are:

                             Male           Female

Sample                  61                  48

Smokers               15                   8

The proportion is calculated using:

p = Smoker/Sample

So, we have:

Male = 15/61 = 0.25

Female = 8/48 = 0.17

The difference is then calculated as:

Difference = 0.25 - 0.17

Evaluate

Difference = 0.08

Hence, the difference in the proportion of males and the proportion of females that smoke is 0.08

the actual area of the basketball court is 4,700 square feet.

Its surface area is a reliable indicator of its overall size. When figuring out the right triangle's squared, the environment is taken into account. The surface area of everything determines its overall size. The total of the volumes from each of the twelve vertical sides makes up the water volume inside a cuboid. Utilize the following formula to get the box's dimensions: The region is represented by 2lh, 2lw, & 2hW. (SA). The area is represented by the flexible shape's entire surface area.

Here,

First, let's find the length and width of the basketball court in feet using the scale:

Length = 1 inch on the drawing represents 8 feet in reality

Length of the drawing = 11.75 inches

Actual length = 8 feet/inch × 11.75 inches = 94 feet

Width = 1 inch on the drawing represents 8 feet in reality

Width of the drawing = 6.25 inches

Actual width = 8 feet/inch × 6.25 inches = 50 feet

Now, we can find the actual area of the basketball court:

Actual area = Actual length × Actual width

Actual area = 94 feet × 50 feet

Actual area = 4,700 square feet

Therefore, the actual area of the basketball court is 4,700 square feet.

The function f is increasing on the interval (6, ∞).

The function f will be increasing in the intervals where f'(x) > 0.

To find these intervals, we can examine the sign of each factor of f'(x), which is (x + 1)²(x - 3)⁵(x - 6)⁴.

We can analyze the sign of f(x) by considering the factors individually:

(x+1)²: This factor is always positive since it is the square of a real number.

(x - 3)⁵: This factor is positive when x>3 and negative when x< 3.

(x - 6)⁴: This factor is positive when x>6 and  negative when x< 6.

We need to consider the overlapping regions of positivity for each factor.

When x>6, all three factors are positive, so  f ′ (x) is positive.

When 3<x<6: In this interval, the factor  (x+1)² is positive, but both (x−3)⁵ and (x−6)⁴ are negative.

Thus, f ′ (x) is negative.

When x<−1: In this interval,  (x+1)² is negative, while (x−3)⁵ and (x−6)⁴ are positive.

Hence, f ′ (x) is negative.

Therefore,  the function f(x) is increasing on the interval x>6.

A sphere thrown upward at a 45-degree angle to the horizontal in a classroom elastically bounces off the ceiling while still rising

At time t = 0, a sphere is launched with an initial velocity at a 45-degree angle to the horizontal in a classroom. The sphere follows a parabolic trajectory as it rises due to the upward component of its initial velocity and experiences the downward pull of gravity. While the sphere is still ascending, it reaches the ceiling and collides with it.

During the elastic collision, the sphere's motion is reversed. It rebounds off the ceiling, changing its direction but maintaining its kinetic energy. As a result, the sphere starts descending with the same speed it had before the collision but in the opposite direction. The angle of descent will also be 45 degrees to the horizontal, mirroring the angle of the initial launch.

Throughout the entire process, neglecting air resistance, the total mechanical energy of the sphere is conserved since the collision with the ceiling is elastic.

The odds of an earthquake is 1 to 50

We need to calculate the odds of an earthquake occurring. Odds are calculated as the ratio of the probability of the event happening to the probability of the event not happening.

The probability of an earthquake occurring is 0.02, so the probability of an earthquake not occurring is 1 - 0.02 = 0.98.

The odds of an earthquake occurring are therefore 0.02 / 0.98 = 0.0204.

To express the odds in the form of a ratio, we can write 0.0204 as a fraction and simplify it.

0.0204 = 204/10000 = 51/2500

The simplified ratio is 51 to 2500.

To convert the ratio to the requested format, we need to subtract 1 from each part of the ratio and express it as a whole number ratio.

51/2500 - 1 = 50/2500 = 1/50

So, the odds of an earthquake occurring are 1 to 50.

Rounded to four decimal places, the p-value is 0.0844.

To determine the p-value for this hypothesis test, we need to follow these steps:

Step 1: State the null and alternative hypotheses.

Null hypothesis: The percentage of readers who own a laptop is 26%.

Alternative hypothesis: The percentage of readers who own a laptop is different from 26%.

Step 2: Determine the test statistic.

We can use a z-test for proportions since we have a large enough sample size and we know the population proportion. The formula for the test statistic is:

z = (p - p) / √(p(1-p) / n)

where p is the sample proportion, p is the hypothesized population proportion, and n is the sample size.

Using the given values, we have:

z = (0.17 - 0.26) / √(0.26(1-0.26) / 100)

z = -1.72

Step 3: Determine the p-value.

Since this is a two-tailed test, we need to find the area in both tails of the standard normal distribution that corresponds to a z-score of -1.72. Using a table or a calculator, we find that the area in the left tail is 0.0422 and the area in the right tail is also 0.0422.

Therefore, the p-value is the sum of the areas in both tails:

Two non-planetary objects in the solar system are asteroids and comets.

What are the non-planetary abjects?

Asteroids are rocky objects that orbit the sun, primarily located in the asteroid belt between Mars and Jupiter. They can range in size from small pebbles to large objects over 500 km in diameter. Asteroids are believed to be remnants from the early solar system, and studying them can provide insights into the formation and evolution of the planets.

Comets are icy objects that originate from the Kuiper belt or the Oort cloud, which are located far beyond the orbit of Neptune. They have a distinct coma (a fuzzy atmosphere) and a tail that can extend for millions of kilometers as they approach the sun. Comets are believed to be remnants from the early solar system and contain information about the formation of the outer planets and the early solar system.

While both asteroids and comets are remnants from the early solar system, they differ in composition and behavior. Asteroids are primarily composed of rock and metal, while comets are made up of ice, dust, and rocky material. Comets also have highly elliptical orbits that can take them far from the sun, while asteroids have more circular orbits.
