The attatchment is what needs to be solved!!

Hi There! Here's your answer:

To make it easier, let's write this in fraction form:

[tex]\frac{2.4}{0.75}[/tex]

Now, multiply the numerator and denominator by 100 to remove the decimal point.

[tex]\frac{2.4}{0.75}[/tex] × [tex]\frac{100}{100}[/tex] = [tex]\frac{240}{75}[/tex]

Now, you can either divide using long division, or you can take out common factors and simplify the fraction that way.

Upon common factor simplification, we get the final fraction to be:

[tex]\frac{240}{75}[/tex] = [tex]\frac{48}{15}[/tex] (Common factor 5) = [tex]\frac{16}{5}[/tex] (Common factor 3)

Therefore, we get the final fraction as [tex]\frac{16}{5}[/tex] which is 3.2.

Correct Answer:

x(t) = 9cos(t)

y(t) = 9sin(t)

z(t) = 54sin(t)cos(t)

What is the parametric equation?

The parametric equation of a curve is a representation of the curve in terms of one or more independent variables (known as parameters), usually represented as t. Each parameter value t corresponds to a unique point (x, y, z) on the curve.

For the given curve, the intersection of the cylinder x²  + y² = 81 and the surface z = 6xy can be found by setting the equation of the cylinder equal to the equation of the surface and solving for x, y, and z in terms of a single parameter t.

Starting with the cylinder: x²  + y² = 81, we can parameterize x and y as follows:

x(t) = 9cos(t)

y(t) = 9sin(t)

Substituting these expressions into the equation of the surface:

z(t) = 6x(t)y(t) = 6 * 9cos(t) * 9sin(t) = 54sin(t)cos(t)

So, the parametric equations of the curve given by the intersection of the cylinder x² + y² = 81 and the surface z = 6xy are:

x(t) = 9cos(t)

y(t) = 9sin(t)

z(t) = 54sin(t)cos(t)

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.

60°, 45° ,30° are special angles with definite values

To solve for a;

sin60 = 2√3/a

√3/2 = 2√3/a

a = 2√3/√3/2

a = 2√3 ×2/√3

a = 2× 2 = 4

The height of the mountain above the level plain is 4465.2 feet

An equation is an expression that contains numbers and variables linked together by mathematical operations of addition, subtraction, multiplication, division and exponents. An equation can either  be linear, quadratic, cubic, depending of the degree of the variable.

Trigonometric ratio is used to show the relationship between the sides and angles of a right triangle.

Let h represent the height of the mountain. Let d represent the distance from the plain to the mountain base

Using trigonometric ratio:

tan(32) = h/d

h = d * tan(32)

Also:

tan(36) = h / (d - 1000)

h = (d - 1000) * tan(36)

Equating:

d * tan(32) = (d - 1000) * tan(36)

d = 7145.9 feet

h = d * tan(32) = 7145.9 * tan(32) = 4465.2 feet

The required standard deviation of the given data is 54.6.

To find the sample standard deviation for the weights of the offensive linemen, we first need to calculate the mean of the sample and then use that to find the variance and standard deviation.

Mean:

The mean (μ) is the sum of all the values in the sample divided by the number of values in the sample. In this case, the mean is:

(359 + 297 + 350 + 254 + 312 + 250 + 359 + 253 + 254 + 326 + 254 + 331) / 12 = 298.75

Variance:

The variance (σ²) is a measure of the spread of the data. It is calculated as the sum of the squared deviations of each value from the mean divided by the sample size minus one. In this case, the variance is:

( (359 - 298.75)² + (297 - 298.75)² + (350 - 298.75)² + (254 - 298.75)² + (312 - 298.75)² + (250 - 298.75)² + (359 - 298.75)² + (253 - 298.75)² + (254 - 298.75)² + (326 - 298.75)² + (254 - 298.75)² + (331 - 298.75)² ) / (12 - 1) = 2987.5

Standard Deviation:

The standard deviation (σ) is the square root of the variance. In this case, the standard deviation is:

√2987.5 = 54.59

Therefore, the sample standard deviation of the weights of the offensive linemen is 54.59 pounds.

Answer:  a. To find f(-2), substitute -2 for x in the function f(x):

f(-2) = 3(-2)² - 2(-2) + 4 = 3(4) - 2(-2) + 4 = 12 - (-4) + 4 = 16

So, f(-2) = 16.

b. To find f(k+1), substitute (k+1) for x in the function f(x):

f(k+1) = 3(k+1)² - 2(k+1) + 4 = 3k² + 6k + 3 - 2k - 2 + 4 = 3k² + 4k + 5

So, f(k+1) = 3k² + 4k + 5.

After the shutdown, the hospital will maintain 126 acute hospital beds available for usage.

Hospitals are classified as general, specialist, or government facilities by the source of their funding. In a medical center, nursing education and patient care are both integrated. A care facility which is smaller than a hospital is called a clinic.

If 28% of the hospital's acute card beds are going to ever be closed, that leaves 100% - 28% = 72% of such beds available for utilization.

72% of 175 beds = 0.72 x 175 = 126 beds

The expression that is equivalent to (1 + cos(x))2Tangent (StartFraction x Over 2 EndFraction) ) is option D. (1 + cos(x))(sin (x))

The expression (1 + cos(x))2Tangent (StartFraction x Over 2 EndFraction) is equivalent to (1 + cos(x))(sin (x)) because of the double angle identity for tangent.

here, we have,

The double angle identity states that tangent of 2 times an angle is equal to 2 times the tangent of that angle divided by 1 minus the square of the tangent of that angle. In other words,

tan(2θ) = 2tan(θ)/(1 - tan2(θ))

In this expression, we have tangent of x/2,

so substituting θ = x/2 gives us:

tan(x) = 2tan(x/2)/(1 - tan2(x/2))

Since cos(x) = 1 - 2sin2(x/2),

we can simplify the expression to:

(1 + cos(x))2tan(x/2) = (1 + 1 - 2sin2(x/2))2tan(x/2)

                               = (2 - 2sin2(x/2))(2sin(x/2)/(1 - sin2(x/2)))

Expanding the product of the two factors gives us the final result:

(1 + cos(x))2tan(x/2) = (2 - 2sin2(x/2))(sin(x)) = (1 + cos(x))(sin(x))

Answer: In a triangle, the medians divide the triangle into six smaller triangles with equal area. This can be proven using the fact that the medians of a triangle are concurrent, meaning they all intersect at a single point called the centroid.

Let's assume that AD = 2BE, then the area of △ADG is equal to four times the area of △BEG. This can be expressed as follows:

Area(△ADG) = 4 * Area(△BEG)

Since GD is one of the medians, it must be equal to one-third of AD. So, we can write:

GD = AD/3

Since the area of △ADG is equal to four times the area of △BEG, we can write:

Area(△ADG) = 4 * Area(△BEG)

(2BE)^2/2 * GD / 2 = 4 * BE^2/2 * EG / 2

Expanding and simplifying the above equation gives us:

BE^2 * GD / 2 = 4 * BE^2/2 * EG / 2

And, finally, dividing both sides of the equation by BE^2/2, we get:

GD = 1/3 * AD

This result holds true regardless of the relative lengths of AD and BE. Hence, the conclusion that GD = 1/3 AD is always true for any triangle △ABC where AD and BE are medians.

Answer:

The expression can be solved using algebraic methods. The result is -(2^7)z^2y^3.

Step-by-step explanation:

The solution to the equation 4/(9)((3/2)z^2y^3)^5 is y^15z^10. This can be solved by using the steps of algebraic manipulation. First, the parentheses can be simplified by multiplying the numerator and denominator together, resulting in 4/27z^2y^3. Then, the exponent can be applied to both terms, resulting in y^15z^10. Finally, this answer can be checked by substituting it into the original equation and verifying that it is true.

The assumption must be false, which means that either x < 8 or y < 8 must hold true.

What is the Proof by Contradiction?

A proof by contradiction is a method of proof in which we assume the opposite of what we want to prove, and then show that this assumption leads to a contradiction. The contradiction then serves as evidence that the assumption must be false, and therefore the original statement must be true.

In this case, we want to prove that for any positive real numbers x and y, if x · y ≤ 50, then either x < 8 or y < 8.

Suppose for the sake of contradiction that x and y are positive real numbers such that x · y ≤ 50 and x ≥ 8 and y ≥ 8. Then, since x and y are positive, we have x · y = xy ≥ 64, which contradicts the assumption that x · y ≤ 50.

Therefore, we have shown that the assumption that x and y are positive real numbers such that x · y ≤ 50 and x ≥ 8 and y ≥ 8 leads to a contradiction.

Hence, the assumption must be false, which means that either x < 8 or y < 8 must hold true.

An integer is a whole number that can be positive, negative, or zero. It is a number without any fractional or decimal component. Integers include the counting numbers (1, 2, 3, ...) and their negatives (-1, -2, -3, ...), as well as 0. Examples of integers are -5, -3, -1, 0, 1, 2, 3, 5, and so on. Integers are used in a variety of mathematical operations, such as addition, subtraction, multiplication, and division, and they play a key role in many areas of mathematics, including number theory, algebra, and discrete mathematics.

(a) Suppose that gcd(a, b) is not equal to 1. Then, there exists a positive integer k such that k divides both a and b. Let a = ka' and b = kb', where a' and b' are relatively prime.

Since there are integers u and v satisfying au + bv = 1, it follows that ka'u + kb'v = k(a'u + b'v) = k. But this means that k divides 1, which is a contradiction. Hence, gcd(a, b) must equal 1.

(b) No, it is not necessarily true that gcd(a, b) = 6 just because au + bv = 6. Consider the counter example a = 4 and b = 2. In this case, we have 2u + 4v = 6, but gcd(a, b) = 2, not 6.

In general, if there are integers u and v satisfying au + bv = k, then gcd(a, b) divides k. However, the converse is not necessarily true; that is, just because gcd(a, b) divides k does not mean there are integers u and v satisfying au + bv = k.
