It would mean the world to me if some one can answer both questions 1 and 2 please help

Answer:

See below.

Step-by-step explanation:

The perimeter = 2*length + 2 * width.

As the ratio is 3:2 the fraction 3 / (3 +2)  is used to find the length:

The measure of the 2 lengths = 3/ (3+2)  * 60

= 3/5 * 60

= 36 cm

So the measure of the length = 18 cm

So the measure of  the width = (60 - 36) / 2

= 24/2

= 12 cm.

Answer:

Step-by-step explanation:

Let's assume the initial number of men at the exhibition is 10x, and the initial number of women is 3x.

After 110 men left, the number of men remaining is 10x - 110.

The total number of people remaining is (10x - 110) + (3x) = 13x - 110.

According to the given information, the number of men remaining (10x - 110) is 5/12 of the total number of people remaining (13x - 110). We can write this as an equation:

10x - 110 = (5/12)(13x - 110)

To solve this equation, we can start by simplifying both sides:

10x - 110 = (65/12)x - (55/6)

To get rid of the fractions, we can multiply both sides of the equation by 12:

12(10x - 110) = 65x - 110(2)

120x - 1320 = 65x - 220

Next, we can bring the x terms to one side and the constant terms to the other side:

120x - 65x = 1320 - 220

55x = 1100

Dividing both sides by 55, we find:

x = 20

Now, we can substitute the value of x back into the initial expressions to find the number of men and women:

Number of men = 10x = 10(20) = 200

Number of women = 3x = 3(20) = 60

Therefore, there were 60 women at the exhibition

(a) The variance of X is undefined since the joint probability density function (PDF) provided does not specify the distribution of X alone.

(b) The variance of Y is undefined since the joint PDF provided does not specify the distribution of Y alone.

(c) The covariance between X and Y is zero since the joint PDF is zero everywhere except for a single point (0, 0).

(d) The variance of X + Y is also undefined since the joint PDF does not provide sufficient information about the distributions of X and Y separately.

The variance of a random variable measures the spread or dispersion of its values around the mean. However, to calculate the variance, we need to know the individual distributions of X and Y, which are not specified in the given joint PDF. Therefore, we cannot determine the variances of X and Y without additional information about their distributions.

Similarly, the covariance between X and Y measures the linear relationship between the two random variables. In this case, since the joint PDF is zero everywhere except for a single point (0, 0), the random variables X and Y are not related, and their covariance is zero.

The variance of the sum of two random variables, Var(X + Y), would require knowledge of the individual variances of X and Y, which are undefined in this context. Without information about their distributions, we cannot compute the variance of their sum.

b. The quadratic approximating polynomial for the function f(x) centered at a=1 is P2(x) = 11 + (x - 1) * f'(1) + (x - 1)^2 * f''(1).

c. Using the linear approximating polynomial P1(x), the approximation of f(1.06) is 11 + (1.06 - 1) * f'(1).

Using the quadratic approximating polynomial P2(x), the approximation of f(1.06) is 11 + (1.06 - 1) * f'(1) + (1.06 - 1)^2 * f''(1).

a. To obtain the linear approximating polynomial P1(x) centered at a=1, we need to consider the first derivative of f(x) evaluated at x=a. The linear polynomial can be constructed as P1(x) = f(a) + (x - a) * f'(a), where f'(a) represents the derivative of f(x) at x=a. In this case, the function f(x) is not provided, so we cannot determine the exact form of P1(x) without knowing the specific function.

b. For the quadratic approximating polynomial P2(x) centered at a=1, we consider the second derivative of f(x) evaluated at x=a. The quadratic polynomial can be expressed as P2(x) = f(a) + (x - a) * f'(a) + (x - a)^2 * f''(a), where f''(a) represents the second derivative of f(x) at x=a.

c. Using the linear approximating polynomial P1(x) to approximate f(1.06), we substitute x=1.06 and a=1 into the equation. The approximation is given by P1(1.06) = 11 + (1.06 - 1) * f'(1).

Similarly, using the quadratic approximating polynomial P2(x) to estimate f(1.06), we substitute x=1.06 and a=1 into the equation. The approximation is given by P2(1.06) = 11 + (1.06 - 1) * f'(1) + (1.06 - 1)^2 * f''(1).

However, since the function f(x) and its derivatives are not provided, the exact values for the approximations cannot be determined without further information.

The distance between the two towers is 30 meters, and the height of the second tower (Tower B) is 90 meters.

We have two towers. Let's call the first tower Tower A, and the second tower Tower B. The height of Tower A is given as 30 meters. The angle of elevation of the top of Tower A from the foot of Tower B is 60 degrees. The angle of elevation of the top of Tower B from the foot of Tower A is 30 degrees. Our goal is to find the distance between the two towers and the height of Tower B.

In triangle ABC, where A is the foot of Tower A, B is the top of Tower B, and C is the top of Tower A:

tan(30 degrees) = AB / BC

Since tan(30 degrees) = 1 / √3, we can rewrite the equation as:

1 / √3 = AB / BC

Cross-multiplying, we get:

BC = AB * √3

In triangle ABC:

tan(60 degrees) = AC / BC

Since tan(60 degrees) = √3, we can rewrite the equation as:

√3 = AC / BC

Substituting the value of BC from Step 3:

√3 = AC / (AB * √3)

Cross-multiplying, we get:

AC = AB * 3

We have two equations:

BC = AB * √3

AC = AB * 3

Dividing equation 2 by equation 1:

AC / BC = 3 / √3

Simplifying, we get:

√3 = 3 / √3

Cross-multiplying, we get:

3 = 3

Since 3 = 3 is a true statement, we can conclude that the two towers are at the same distance as their heights. Therefore, the distance between the two towers is 30 meters.

Using the value of the distance between the towers (30 meters), we can substitute this value into one of the previous equations to find the height of Tower B. Let's use equation 2:

AC = AB * 3

Substituting AB with the distance (30 meters):

AC = 30 * 3

Simplifying, we find:

AC = 90 meters

Therefore, the height of Tower B is 90 meters.

If the moon is setting at 6 a.m., we can determine its phase based on its position in relation to the Sun and Earth.

Considering the options provided:

a. First quarter: The first quarter moon is typically visible around sunset, not at 6 a.m. So, this option can be ruled out.

b. Third quarter: The third quarter moon is typically visible around sunrise, not at 6 a.m. So, this option can be ruled out.

c. New: The new moon is not visible in the sky as it is positioned between the Earth and the Sun. Therefore, it is not the phase of the moon that is setting at 6 a.m.

d. Full: The full moon is typically visible at night when it is opposite the Sun in the sky. So, this option can be ruled out.

e. Waning crescent: The waning crescent phase occurs after the third quarter moon and appears in the morning sky before sunrise. Given that the moon is setting at 6 a.m., the most likely phase is the waning crescent.

Answer:

\(y=-\frac{1}{3}x - 3\)

Step-by-step explanation:

Hi there!

We want to write an equation of the line that is perpendicular to y=3x-1 and passes through (3, -4)

Perpendicular lines have slopes that multiply to get the value of negative one.

Let's first figure out the slope of y=3x-1

The line is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

3 is in the place of where m is, so 3 is the slope of y=3x-1

Now let's find the slope of the line perpendicular to it.

We can use a formula like this:

\(m_1 * m_2= -1\)

If 3 is \(m_1\), then:

\(3*m_2=-1\)

Divide both sides by 3

\(m_2=-\frac{1}{3}\)

So the slope of the perpendicular line is -1/3

We can write this equation in slope-intercept form. So far, we know that the equation of the line is:

y=\(-\frac{1}{3}x + b\)

So let's find b

Remember that we are given that the line passes through the point (3, -4). That means that point is a solution to the equation that we're trying to find. Therefore, the values of that point should create a true statement when plugged into the equation.

So we can substitute 3 as x and -4 as y to help solve for b.

-4=\(-\frac{1}{3}(3)+b\)

Multiply

-4=\(-\frac{3}{3}\) + b

Simplify

-4 = -1 + b

Add 1 to both sides to isolate b

-3 = b

Substitute -3 as b in the equation

\(y=-\frac{1}{3}x - 3\)

A domain of a function refers to "all the values" that go into a function. The domain of a function is the set of all possible inputs for the function. The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. The domain of a function is the set of values that we are allowed to plug into our function.

This set is the x values in a function such as f(x).

The range of a function is the set of values that the function assumes. This set is the values

Given that f(t) has units of N and t has units of s. And 1N = 1kg.m/s²Therefore the dimensions of f(t) are, [f(t)] = N.As the dimensions of t are [t] = s.

Now the integral of f(t) over time t=0 to t=tl, is given by;`[∫_0^(tl)]f(t)dt`The units of momentum of the t-shirt are the units of the integral`∫_0^(tl) f(t) dt`Where f(t) has units of N and t has units of s.

According to the formula for momentum, p = mv where p is the momentum of the object of mass m moving with velocity v.

The dimensions of momentum are`[M][L]/[T]^2`Where `[M]` is the dimension of mass, `[L]` is the dimension of length, and `[T]` is the dimension of time.As N = kg.m/s², we can write the dimensions of

f(t) as;N = kg.m/s²`[f(t)] = [kg.m]/[s²]`

We can now substitute these dimensions into the integral and simplify as follows;

`[p] = [∫_0^(tl) f(t) dt]

= [f(t)][t]

= [N][s]

= [kg.m/s²] x [s]

Area of the triangle = 0

Step-by-step explanation:

We are given the vertices of a triangle as: (- 8,4 ), (- 6,6), (- 3,9)​

The formula to find the Area of the triangle =

Where :

(x₁, y₁) =  (- 8,4 )

(x₂, y₂) = (- 6,6)

(x₃, y₃) =  (- 3,9)

Area of the triangle = 1/2[-8(6 - 9) + -6(9 - 4) + -3(4 - 6)]

= 1/2[ (-8 × -3) +( -6 × 5) +( -3× -2)]
