For the function y = -2+5sin(pi/12(x-2)), what is the maximum value?

Answers

Answer 1

Answer: To get the function y = -2+5sin(pi/12(x-2)), the maximum value can be determined by differentiating the function and equating it to zero. The value of x will give the maximum value of the function.
dy/dx = 5 cos (pi/12 (x-2)) (pi/12)
dy/dx = 5 pi/12 cos(pi/12 (x-2))

Equate to zero:
5 pi/12 cos(pi/12 (x-2)) =0
pi/12 (x-2) = 3pi/2
x = 8

Substituting,
y= -2 + 5sin( pi/12 (8-2)
y = -1.86

Answer:

Option A is right

Step-by-step explanation:

The graph represents the results of a survey where 400 people were asked to identify the preferred TV channcel.

Of those the data collected gave

WKOD 13%

WANR 22%

WCLM 24%

WWCN 41%

Ratio of people who preferred WANR to those who preferred WCLM

= 22%/24%

=11:12

Hence answer is 11:12

WANR - 22%
WCLM - 24%

Ratio WANR/WCLM=0.22/0.24=11:12

The school hall is 4 times as long as it is wide. If the perimeter is 55m, what is the length? and what is the width?

Answers

-- The width of the school is ' W '. We don't know what that is yet,
but we're going to find out.

-- We're told that the length is 4 times as much. So the length is ' 4 W '.

-- Perimeter is (2 widths) + (2 lengths).

2 widths = 2 W
2 lengths = 8 W
Perimeter = 10 W

-- We're also told that the perimeter is 55m. That's just what we need.

10 W = 55 m

Divide each side of this equation by 10:

W = 5.5 m

There's the width !
The length of the hall is 4 times as much.

Length = 4 W = 22 m

pdcms sold a total of 110 tickets for the school play. an adult ticket is $7 and a student ticket is$4. the school collected a total of $569 how many adults and how many students attended the play

Answers

Let the number of adult tickets be x.
Since there are 110 tickets sold in all, student tickets will be 110 - x.

Cost for adult tickets = 7*x = 7x
Cost for student tickets = 4*(110 -x) = 4*110 - 4*x = 440 - 4x

Total cost = $569

7x + (440 - 4x) = 569

7x + 440 - 4x = 569

7x - 4x = 569 - 440

3x = 129

x = 129/3

x = 43

Recall x is the number of adults tickets = 43

Student tickets = (110 - x) = 110 - 43 = 67

Therefore from the number of tickets sold it is safe to assume that 43 adults and 67 students attended the play.
