Answer:

1) 0, 180

2) 90

3) 3pi/2

4) pi/2, -3pi/2

5) 90, 270

6) 0

7) pi

8) -2pi, 0, 2pi

Step-by-step explanation:

1) sinx = 0

x = 0, 180, 360

2) sinx = 1

x = 90

3) sinx = -1

x = 270 or 3pi/2

4) sinx = 1

x = pi/2, pi/2 - 2pi = -3pi/2

5) cosx = 0

x = 90, 360

6) cosx = 1

x = 0, 360

7) cosx = -1

x = pi

8) cosx = 1

A local petting zoo had a total of 98,464 visitors last year. The zoo was open every day except thanksgiving, Christmas, and New

riadik2000 [5.3K]

Answer:

The average number of visitors per day is 272.

Step-by-step explanation:

Total number of visitors in the zoo in a year = 98,464

Now,we know that 1 YEAR = 365 DAYS

Also, the zoo was closed on thanksgiving, Christmas, and New Year's Eve

So, the Number of days zoo was open = Total Days in year - 3 days

= 365 - 3 = 362 days

⇒Number of visitors in 362 days = 98,464

So, $\textrm{Number of visitor per day} = \frac{\textrm{Total number of visitors in 352 days}}{\textrm{352 days}}$

$= \frac{98,464}{362} = 272$

or, the number of people visiting per day is 272.

Hence, the average number of visitors per day is 272.

Use the formula A=bh , where A is the area, b is the base length, and h is the height of the parallelogram, to solve this proble

harkovskaia [24]

We know that:

A = 1440
H = 32

So you need to work backwards to find base.

1440 / 32 = 45

We can check our work:

32 x 45 = 1440

B = 45
