The terminal point of an angle is (0,1), and we are asked to determine the tangent of the said angle. We can exemplify the problem in the following diagram.

Even though the point (0,1) lies in the y-axis, the idea if the diagram is to show that the terminal point of an angle represents the values of the adjacent and opposite sides of a triangle. Therefore, in the given terminal point the triangle has adjacent side 0 and opposite side 1. Now let's remember the definition of the function tangent:

Replacing the values we get:

Because we have a division by zero the function tangent of theta is undefined for this terminal point.

Here we have a dilation of scale factor 2.

We can see that bot figures we have the same slope, so we just have a dilation of scale factor K to go from figure A to figure B.

To find the value of K, notice that for some side length L in figure A, the correspondent length L' in figure B must be:

L' = K*L

Here if we use the left sides, we will get:

for figure A; L= 2

for figure B: L = 4

4 = K*2

4/2 = K

2 = K

So this is a dilation of scale factor k = 2.

Step-by-step explanation:

Answer:

To calculate 2 3/4 of 500 grams, follow these steps:

1. Convert the mixed number to an improper fraction:

2 3/4 = (2 x 4 + 3)/4 = 11/4

2. Multiply the improper fraction by 500:

11/4 x 500 = (11 x 500)/4 = 2,750/4

3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:

2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2

Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

Step-by-step explanation:

A => 4.05
b =>5.95

now they  told in the coffee blend their ratio is 2:1 :: B:A
So if we take x amounts of A then 2x amount of B
So cost of A => x * 4.05
So cost of B => 2x * 5.95

And result is given 606.1

Hence
x * 4.05 + 2x*5.95 = 606.1

Solve and get x = 38

The statement which is true include the following: A. The median can not possibly appear as a number in the data set.

In Mathematics, a median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.

In Mathematics, a mode can be defined as a statistical term that is used to denote the value that appears most often or occurs repeatedly in a given data set.

In this context, we can reasonably infer and logically deduce that the median differs from the mode of a given data set.

Answer:

=to 50

Step-by-step explanation:

The probability that the total weight exceeds 290 Kg is 0.23 and this can be determined by using the normal distribution formula.

Given :

The mean of T is given by the following calculation:

\(\mu_T = 4\times 65\)

\(\mu_T = 260\)

The standard deviation of T is given by the following calculation:

\(\sigma^2_T=12^2+12^2+12^2+12^2\)

\(\sigma_T = \sqrt{4\times 12^2}\)

\(\sigma_T = 24\)

To determine the probability P(T > 290) use the formula of normal distribution which is given below:

\(\rm P(T>290) = \int\limits^{9999}_{290} {\dfrac{e^{\frac{-(x-260)^2}{24}}}{24\sqrt{2\pi} } \, dx\)

By simplifying the above integration the value of the probability is given by:

P(T > 290) = 0.23

So, the probability that the total weight exceeds 290 Kg is 0.23.

Step-by-step explanation:

       To show your work for this problem, you will write out every step that you take to solve for x.

Given:

     3x - 5 = x + 2 - 10 - 7x

Combine like terms:

     3x - 5 = - 6x - 8

Add 5 and 6x to both sides of the equation:

     9x  = - 3

Divide both sides of the equation by 9 and simplify the fraction:

Answer:

A.

Step-by-step explanation:

A quadrilateral inscribed in a circle has its opposite angles adding up to 180°

So

<NOP + <M = 180

4x+8x-24 = 180

12x = 180+24

12x = 204

Dividing both sides by 12

x = 17

<NOP = 4(17)

Answer:

$21473.33

Step-by-step explanation:

Let the original price be x

76% discount gives $153.60

This means 24/100 * x = $153.60

X= 153.60 * 100 /24 = $21473.33

The original price of the sofa is $21473.33.

Discount is the difference in price between the selling price of an object and the price listed on the object marked price.

Given that, a sofa is being sold for $153.60, which was on the 76% discount.

Let the original price be x,

x - 76% of x = $153.60,

⇒ 24/100 · x = $153.60

⇒ x = 153.60 · 100 /24 = $21473.33

Hence, the original price of the sofa is $21473.33.

Answer: It is a reflection of Reflections of You (second location) in the x-axis.

Step-by-step explanation: Based on the given information, the relationship between the new location (The Gridiron) and the previous locations can be determined.

The correct answer is:

   It is a reflection of Reflections of You (second location) in the x-axis.

The coordinates of the first three checkpoints of The Gridiron (A''(0,−5), B''(9,−5), and C''(4,−5)) indicate that they have the same y-coordinate (-5) as the corresponding checkpoints in the second location, Reflections of You. However, there is no indication of a reflection in the y-axis or any transformation related to the first location, Transformation Fitness Studios. Therefore, the correct answer is that The Gridiron is a reflection of Reflections of You in the x-axis.

Answer: 0.16

Step-by-step explanation:

Let X be a random variable that represents the heights of women at a large university are approximately bell-shaped, with a mean of 66 inches and standard deviation of 3 inches.

According to the Empirical Rule, for bell-shaped distributions, about 68% of the values fall within 1 standard deviation of the mean.

About 68% woman have height between ( 66-3) inches and (66+3) inches.

i.e. About 68% woman have height between 63 inches and 69 inches.

The percentage of woman have height either less than 69 inches or greater than 69 inches =100% - 68%= 32% [both share equal area on curve.]

The percentage of woman have height  is 69 inches or taller = 32%÷2

= 16%

Hence, the probability that a randomly selected woman from this university is 69 inches or taller =16%=0.16

The Fibonacci sequence is the sequence in which the numbers are written such that each succeeding number is sum of two preceding numbers.

The Fibonacci sequence is defined recursively as follows:

F0 = 0

F1 = 1

For n > 1, Fn = Fn-1 + Fn-2

(b) The sequence of partial sums is:

S0 = 0

S1 = 0 + 1 = 1

S2 = 0 + 1 + 1 = 2

S3 = 0 + 1 + 1 + 2 = 4

S4 = 0 + 1 + 1 + 2 + 3 = 7

S5 = 0 + 1 + 1 + 2 + 3 + 5 = 12

(c) A closed formula for the sequence of partial sums in terms of Fn is not possible, since the sequence of partial sums depends on the values of all previous terms in the Fibonacci sequence. However, it is possible to express the nth term of the sequence of partial sums, Sn, in terms of the nth term of the Fibonacci sequence, Fn, using the following formula:

Sn = F0 + F1 + ... + Fn = (F0 + F1) + (F1 + F2) + ... + (Fn-1 + Fn) = F1 + F2 + ... + Fn + F0 + F1 + ... + Fn-1 = 2Sn-1 - Fn + F0

This formula can be derived by considering the previous term in the sequence of partial sums and adding the current term of the Fibonacci sequence to it.
