1 answer:
Answer:
1) Photographer B (4%)
2) Photographer D (27%)
3) Photographer C (29%)
4) Photographer A (40%)
Step-by-step explanation:
<u><em>The correct question is</em></u>
Four photographers are taking pictures at a school dance. Photographer A takes 2/5 of the pictures, Photographer B takes 4% , Photographer C takes 0.29 , and Photographer D takes 27/100 . Which choice lists the photographers in order from least to greatest by the amount of pictures they take?
we know that
1) Photographer A takes 2/5 of the pictures
That means
the amount of pictures take by photographer A in percent form is equal to multiply the fraction by 100
---> percentage form
2) Photographer B takes 4%
3) Photographer C takes 0.29
That means
the amount of pictures take by photographer C in percent form is equal to multiply the decimal number by 100
---> percentage form
4) Photographer D takes 27/100
That means
the amount of pictures take by photographer D in percent form is equal to multiply the fraction by 100
---> percentage form
Lists the photographers in order from least to greatest by the amount of pictures they take
1) Photographer B (4%)
2) Photographer D (27%)
3) Photographer C (29%)
4) Photographer A (40%)

The values of cosine Ф and cotangent Ф are and -1
Step-by-step explanation:
When a terminal side of an angle intersect the unit circle at
point (x , y), then:
- The x-coordinate is equal to cosine the angle between the positive part of x-axis and the terminal side
- The y-coordinate is equal to sine the angle between the positive part of x-axis and the terminal side
- If x and y coordinates are positive, then the angle lies in the 1st quadrant
- If x-coordinate is negative and y-coordinate is positive, then the angle lies in the 2nd quadrant
- If x and y coordinates are negative, then the angle lies in the 3rd quadrant
- If x-coordinate is positive and y-coordinate is negative, then the angle lies in the 4th quadrant
∵ The terminal ray of angle Ф intersects the unit circle at point
- According to the 1st and 2nd notes above
∴ cosФ = x-coordinate of the point
∴ sinФ = y-coordinate of the point
∵ The x-coordinate of the point is negative
∵ They-coordinate of the point is positive
- According the the 4th note above
∴ Angle Ф lies in the 2nd quadrant
∵ x-coordinate =
∴ cosФ =
∵ y-coordinate =
∴ sinФ =
- cotФ is the reciprocal of tanФ
∵ tanФ = sinФ ÷ cosФ
∴ cotФ = cosФ ÷ sinФ
∴ cotФ = ÷
∴ cotФ = -1
The values of cosine Ф and cotangent Ф are and -1

Answer:
= 5n
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 10 - 5 = 15 - 10 = 20 - 15 = 25 - 20 = 30 - 25 = 5
This indicates the sequence is arithmetic with explicit formula
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 5 , then
= 5 + 5(n - 1) = 5 + 5n - 5 = 5n
