Answer:

Step-by-step explanation:

The height of the tree which is the opposite side of the right triangle is 145 meters.

The angle of elevation is 36 degrees.

The situation forms a right angle triangle.

Therefore,

base of the triangle = 200 m

Hence, using trigonometric ratios,

tan 36 = opposite / adjacent

tan 36 = x / 200

x = 200 tan 36

x = 200 × 0.726542528

x = 145.308505601

x = 145.31 m

The theory of emotion that best explains these results is the James-Lange theory of emotion.

According to the James-Lange theory of emotion, our emotional experience is a result of our physiological responses to stimuli. This theory suggests that emotions are a direct consequence of bodily changes triggered by external events. In the given scenario, Teddy and Owen were both given the same drug that produced general arousal. Teddy's emotional state was described as happy when placed in a room with a happy person, while Owen's emotional state was described as angry when placed in a room with an angry person. The James-Lange theory would explain Teddy's happiness and Owen's anger as a result of the physiological responses elicited by the drug and the presence of the happy and angry individuals. Teddy's general arousal may have led to positive physiological changes that she interpreted as happiness, while Owen's general arousal may have led to negative physiological changes that he interpreted as anger. This suggests that our emotions are influenced by our bodily responses to stimuli and that different physiological states can lead to different emotional experiences.

Hourly service is $ 75

Required equation

y = 75x + 15

What is linear equation?

At first it is important to know about equation

Equation shows the equality between two algebraic expressions by connecting the two algerbraic expressions by an equal to sign.

A one degree equation is known as linear equation.

From the table, it is seen that hourly rate for 2 hours is $165

Now cost for diagonosing the car = $15

Rate for 2 hours = $(165 - 15) = $150

Rate for 1 hour = $\(\frac{150}{2}\)

Rate for 1 hour is $75

Now for the equation

Rate for x hours = $75x

The formula for allocation deviation is as follows:σA = (w1σ1^2 + w2σ2^2 + … + wσn^2)^(1/2)σB = (w1σ1^2 + w2σ2^2 + … + wσn^2)^(1/2)

Here,

σ1 = 15%

σ2 = 10%

w1 = 50%,

w2 = 50%

Substituting the values in the above formula:

σA = (0.5 × 0.15^2 + 0.5 × 0.10^2)^(1/2)

= (0.0225 + 0.0100)^(1/2)

= 0.0158 = 1.58%σB

= (0.5 × 0.15^2 + 0.5 × 0.10^2)^(1/2)

= (0.0225 + 0.0100)^(1/2)

= 0.0158

= 1.58%

Hence, the correct option is

D. σ(A) = 14.14%;

Answer:

Step-by-step explanation:

Henry is 3 more than twice Nicholas' age. You can write this as :

H = 3 + 2N

Marcus is 9 less than 6 times Nicholas' age:

M = 6N - 9

Since Henry and Marcus are twins, this means H = N.

3 + 2N = 6N - 9

Add 9 to both sides

12 + 2N = 6N

Subtract 2N from both sides

12 = 4N

Divide both sides by 4 to find N.

N = 12/4 = 3

The distance between point P and line l is

1. Distance = 2√2

2. Distance =0

3. Distance =6

4. Distance =1

5. Distance =√10

To find the distance between a point and a line, we can use the formula for the distance between a point and a line in the coordinate plane. The formula is:

Distance = |Ax + By + C| / √(A² + B²)

1. Line & contains points (0, -3) and (7, 4). Point P has coordinates (4,3).

The equation of the line is y = x - 3. We can rewrite it as x - y + 3 = 0.

So, Distance = |4 - 3 + 3| / √(1² + (-1)²)

= |4| / √2

= 4 / √2

= 2√2

2. Line & contains points (11, -1) and (-3, -11). Point P has coordinates (-1, 1).

The equation of the line is y = -2x - 1. We can rewrite it as 2x + y + 1 = 0.

So, Distance = |2(-1) + 1 + 1| / √(2² + 1²)

= |-2 + 2| / √5

= 0 / √5

= 0

3. Line & contains points (-2, 1) and (4, 1). Point P has coordinates (5, 7).

The equation of the line is y = 1.

So, Distance = |0(5) + 7 - 1| / √(0² + 1²)

= |6| / √1

= 6

4. Line & contains points (4, -1) and (4, 9). Point P has coordinates (1, 6).

The line is vertical, and its equation is x = 4.

so, Distance = |1 - 4 + 4| / √(1² + 0²)

= |-1| / √1

= 1

5. Line & contains points (1, 5) and (4, -4). Point P has coordinates (-1, 1).

The equation of the line is y = -3x + 8.

So, Distance = |3(-1) + 1 - 8| / √(3² + 1²)

= |-3 - 7| / √10

= |-10| / √10

= 10 / √10

= 10√10 / 10

= √10

The vector product (cross product) of M and N is -10j + 155k - 362j - 6k + 24i.

The vector product (cross product) of two vectors M and N is calculated using the determinant method. The cross product of M and N is denoted as M x N. To calculate M x N, we can use the following formula,

M x N = (2 * (-1) - (-4) * (-6))i + ((-4) * 61 - 31 * (-1))j + (31 * (-6) - 2 * 61)k

Simplifying the equation, we get,

M x N = -10j + 155k - 362j - 6k + 24i

Therefore, the vector product M x N is -10j + 155k - 362j - 6k + 24i.

The difference quotient of \(f(x) = x^2 - 6x + 5\) is is 2x - 6 + h.

To find the difference quotient for the function \(f(x) = x^2 - 6x + 5\), we need to evaluate

(f(x + h) - f(x)) / h, where h is not equal to 0.

First, let's find f(x + h):

\(f(x + h) = (x + h)^2 - 6(x + h) + 5\)

\(= x^2 + 2hx + h^2 - 6x - 6h + 5\)

\(= x^2 - 6x + 5 + 2hx - 6h + h^2\)

Now, we can substitute the values of f(x + h) and f(x) into the difference quotient:

\((f(x + h) - f(x)) / h = ((x^2 - 6x + 5 + 2hx - 6h + h^2) - (x^2 - 6x + 5)) / h\)

= (2hx - 6h + h^2) / h

= 2x - 6 + h

Therefore, the difference quotient of \(f(x) = x^2 - 6x + 5\) is 2x - 6 + h.

The right alternative to replace the question mark (?) is nik.

The given series is wfb, tgd, qhg. To find the right alternative to replace the question mark (?), we need to identify the pattern in the series.

Looking at the series, we can observe that the first letter in each term is moving back two steps in alphabetical order, while the second letter is moving forward one step, and the third letter is moving forward one step and then moving forward two steps which means that it is moving forward with "n+1" steps where n = 0, 1, 2, 3,...

Applying this, we can determine the next term in the series:

w → t → q → n

f → g → h → i

b → d → g → k

To detect an odd number that is 40 or more in a variable named x, the correct if statement(s) that apply are: if x >= 40 and x % 2 != 0: if x % 2 != 0 and x >= 40:

if x >= 40 and x % 2 != 0: checks two conditions. First, it checks if x is greater than or equal to 40 (x >= 40). This ensures that the number is 40 or more. Then, it checks if x modulo 2 is not equal to 0 (x % 2 != 0). This condition checks if the number is odd since odd numbers have a remainder of 1 when divided by 2.

if x % 2 != 0 and x >= 40: also checks two conditions. First, it checks if x modulo 2 is not equal to 0 (x % 2 != 0). This condition checks if the number is odd since odd numbers have a remainder of 1 when divided by 2. Then, it checks if x is greater than or equal to 40 (x >= 40). This condition ensures that the number is 40 or more.

Answer:

Step-by-step explanation:

m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.

m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.

Step-by-step explanation:

148 + x = 180

x = 180 - 148

x = 32

Find m<CAB basically means find the measure of the angle of A ( m<A )

m<B + m<A + x = 180

85 + m<A + 32 = 180

117 + m<A = 180

m<A = 180 - 117

m< A = 63, so m<CAB = 63

And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.

So m<BCA = 32

The expectation, E(X²) of the random variable X is 2/3

Here we are given that the pdf or the probability density function of X is given by

4x³, where 0 < x < 1

clearly this is a continuous distribution. Hence we know that the formula for expectation for random variable X with probability density function f(x) is

∫x.f(x)

and, the formula for expectation

E(X²) = ∫x².f(x)

Hence here we will get

\(\int\limits^1_0 {x^2 . 4x^3} \, dx\)

here we will get the limits as 0 and 1 as we have been given that x lies between 0 and 1

simplifying the equation gives us

\(4\int\limits^1_0 {x^5} \, dx\)

we know that ∫xⁿ = x⁽ⁿ⁺¹⁾ / (n + 1)

hence we get

\(4[\frac{x^6}{6} ]_0^1\)

now substituting the limits will give us

\(4[\frac{1^6 - 0^6}{6} ]\)

= 4/6

= 2/3
