Step-by-step explanation:

Formula for area of cone: 1/3h\(\pi\)r²

Since there is a 45 - 45 - 90 triangle and 27 meters is one of the congruent sides, the other side must also be 27 meters.

Then, just plug it in.

1/3 x 27m x 3.1415... x (27m)²

= (27m)³ x 3.1415 x 1/3

= 20,611.3815m³

≈ 20,612.0 m³

The particular solution to the given differential equation dy/dx = sin(x) - 3 is,  y = - cos x - 3 x + 11π/2.

Given the differential equation is,

dy/dx = sin(x) - 3

dy = (sin x - 3) dx

Integrating the above differential equation we get,

∫ dy = ∫ (sin x - 3) dx

∫ dy = ∫ sin x . dx - ∫ 3 . dx

y = - cos x - 3 x + C, where C is the Integrating Constant. ............ (i)

Here the initial condition is when x = 3π/2 then y = π so putting this in equation (i) we get,

π = - cos (3π/2) - 3 (3π/2) + C

- 9π/2 + C = π

C = π + 9π/2 = 11π/2

Hence the particular solution of the differential equation is, y = - cos x - 3 x + 11π/2.

Answer:5

Step-by-step explanation:

Answer:

Add each given variable

(6x + 10) + (x + 2) + x = 8x + 12

The sum of all the angles equals 180ᴼ

8x + 12 = 180

Subtract 12 from both sides

8x = 168

Divide by 8 on both sides

x = 21

Now plug in 21 for each x to find the measure of each angle.

(6[21] + 10) = 126 + 10 = 136ᴼ

(21 + 2) = 23ᴼ

x = 21ᴼ

Step-by-step explanation:

The measurement of altitude BE is 4 unit.

As the average level of the sea's surface, sea level is used to measure altitude. A high altitude is defined as being significantly higher than sea level, such as Mount Everest. It is referred to as having a low altitude when something is closer to the ground, like a plane coming in to land.

As ABCD is rectangle

AD = BC = 12

ΔABC = ΔBCD

BE = FD

5² = 3²+BE²

AE = 3

BE = √(5²-3²)

BE = 4

Thus, The measurement of altitude BE is 4 unit.

False, a quadratic and a curvilinear term are not the same.

Step-by-step explanation:

The union of two sets is to avoid counting the same elements twice.

The mathematical logic subfield of set theory investigates sets, which can be loosely defined as collections of objects. Although any object can be combined into a set, set theory, as a mathematical discipline, focuses primarily on those that are relevant to mathematics as a whole.

Given union of set

(A ∪ B),

The set of all objects that are members of either A or B, or both, is the union of the sets A ∪ B.

let us take example,

A = { 1, 2, 3, 4}

B = {3, 4, 5, 6, 7}

(A ∪ B) = { 1, 2, 3, 4} ∪  {3, 4, 5, 6, 7}

we can simply write all of A and B's elements in a single set to avoid duplicates to find A U B.

(A ∪ B) = {1, 2, 3, 4, 5, 6, 7}

Hence the  union of two sets is a set that contains all the elements of both set and avoid duplicates.

Answer:

y = -0.5x + 3

Step-by-step explanation:

The equation of a linear model is generally represented as;

y = mx + b

where m

is slope and b is the y-intercept

We can get slope by using the slope equation

m =

(y2-y1)/(x2-x1)

(x1,y1) = (-4,5)

(x2,y2) = (4,1)

m = (1-5)/(4 + 4) = -4/8 = -0.5

The equation is thus;

y = -0.5x + b

to get b, we substitute any of the two points coordinates

1 = -0.5(4) + c

1 = -2 + c

c = 2 + 1

c = 3

(4) (2x) + (4) (1) = 6x + 10 Distribute

8x + 4 = 6x + 10

8x + 4 − 6x = 6x + 10 − 6x  subtract 6x from both sides

2x + 4 = 10

Hallo, I will help you with the problem T^T

Step-by-step explanation:

3.75r + 2.75b = 22.25

3.75r = The amount a red can costs, MULTIPLIED BY the amount of red cans they bought!

2.75b = The amount a black can costs, MULTIPLIED BY the amount of black cans they bought!

So this means that they bought:

3 cans of red paint.

And 4 cans of black paint.

Now you may be thinking, how do you know?

If you multiply the COST 3.75, by 3 cans of red paint, you get 11.25

And then if you multiply the COST of the black paint (The cost for a can of black paint is 2.75) multiply that by 4, you get 11 :0

So add 11 + 11.25 and you get 22.25 :]

The conditions for the sampling distribution of a difference in proportions to be approximated by a normal distribution are: n1 ≥ 5, n2 ≥ 5, n1p1 ≥ 5, n1p2 ≥ 5, n2p1 ≥ 5, n2p2 ≥ 5.

The formula provided seems to be a combination of various terms related to sample sizes (n1 and n2) and probabilities (p1 and p2). It appears to be related to the conditions for the approximation of the sampling distribution of a difference in proportions by a normal distribution.

In general, for the sampling distribution of a difference in proportions to be approximated by a normal distribution, the following conditions should be satisfied:

1. Both sample sizes (n1 and n2) are greater than or equal to 5.

2. For each sample, the product of the sample size (ni) and the probability of success (pi) is greater than or equal to 5 (n1p1 ≥ 5, n1p2 ≥ 5, n2p1 ≥ 5, n2p2 ≥ 5).

Answer:

12 units

Step-by-step explanation:

The lactus rectum for a parabola is equal to 4 times the length of the focus from the vertex. Therefore, we need to determine the focus \((h+p,k)\) by using the equation \((y-k)^2=4p(x-h)\) for a vertical parabola.

We can deduce that \(k=-3\), \(h=1\), and \(p=3\). Therefore, the focus of the parabola is \((1+3,-3)\) or \((4,-3)\).

Because the focus is \((4,-3)\), then it is 3 units away from the vertex \((4,0)\), making the length of the latus rectum 3*4=12 units.

The value of M can be found by evaluating the definite integral of the given function over the given interval.

Start with the integral: \(∫[0, 12] (12x + 30)/(x^2 + 2x - 8) dx.\)

Factor the denominator:\((x^2 + 2x - 8) = (x + 4)(x - 2).\)

Rewrite the integral using partial fraction decomposition:\(∫[0, 12] [(A/(x + 4)) + (B/(x - 2))] dx\), where A and B are constants to be determined.

Find the values of A and B by equating the numerators: \(12x + 30 = A(x - 2) + B(x + 4).\)

Solve for A and B by substituting suitable values of \(x (such as x = -4 and x = 2)\) to obtain a system of equations.

Once A and B are determined, integrate each term separately: \(∫[0, 12] (A/(x + 4)) dx + ∫[0, 12] (B/(x - 2)) dx.\)

Evaluate the integrals using the antiderivatives of the respective terms.

The value of M will depend on the constants A and B obtained in step 5, which can be substituted into the final expression.

x = 45/2 or 22.5

Step-by-step explanation:

Since we are given CDE ~ KLM, we know that C is similar to K, D is similar to L, and E is similar to M. The problem asks to find DE, so by comparison, it is known that DE is similar to LM.

From the two triangles, KM is similar to CE, and we can see that the ratio between the two is 8:15. We are given LM, which is 12, so we can find x using this equation to compare the smaller triangle to the bigger one:

KM/CE = LM/DE

Plug in your given values:

8/15 = 12/x

Find x:

x = 45/2 or 22.5
