HELP!! I'm not sure what goes in the blank.

Answer:

10sin^{2} (β)

Step-by-step explanation:

We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10sin^{2} (β) on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10sin^{2} (β).

You can also use double angle formulas from the previous step:

(sin(2β) = 2 sin(β) cos(β))and find that:

5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =

10sin^{2} (β) cos(β)

But since cos(β) is already present, we can see that the answer is 10sin^{2} (β)

A small theater sold 72 tickets for a
Mariulka [41]

Answer:

Number of child tickets = 9

Number of adult tickets = 36

Number of senior tickets = 27

Step-by-step explanation:

Given:

The ratio of adult tickets to child tickets = 4:1

Ratio of adult  tickets to senior tickets = 4:3

Number of total tickets = 72

Find:

The number of each ticket.

Computation:

Ratio between Adult to senior to child = 4:3:1

So,

Number of child tickets = [1 / (4+3+1)]Total tickets

Number of child tickets = [1 / (8)]72

Number of child tickets = 9

Number of adult tickets = [4 / (4+3+1)]Total tickets

Number of adult tickets = 36

Number of senior tickets = [3 / (4+3+1)]Total tickets

Number of senior tickets = 27

How many whole numbers are between 1 and 50 that are divisible by 2?
kupik [55]

Answer:

25

Step-by-step explanation:

The first number in the range 1 - 50 that is divisible by 2 is 2 itself.  Then 4, 6, 8, ....

Here's one way to think and count:

2 \rightarrow 1\\4 \rightarrow 2\\6 \rightarrow 3\\8 \rightarrow 4\\\vdots\\50\rightarrow 25

In the table, the number on the right is <u>half</u> the number on the left.  The numbers on the right are just counting numbers (natural numbers), so there are 25 even numbers between 1 and 50.

Assume you have collected data pairs (x, y) on a certain variety of tree. x is the number of weeks since the tree was planted an
Dvinal [7]
I'm not sure what the answers are, but I can help. If you go to the x axis and search for 50, then go straight up to the line of best fit, you'll find the estimated height of the tree. It appears to be about 70. 

Hope this helps!
