For tan(405 degrees):

405° = 360° + 45° = 45° = 9π/4 = π/4 

tanx = sinx/cosx 

sin(π/4) = √2/2 

cos(π/4) = √2/2 

[√2/2] / [√2/2] = 1 

<span>Therefore: tan(405°) = 1

You may use the same method for the other given functions.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

MaRussiya [10]
To convert these numbers to a percent, divide the subset by the total, then multiply by 100.
$241.50 (subset) divided by $1,050 (total)
Is 0.23. Next, multiply the quotient (0.23) by 100 to get your answer.
0.23*100 = 23.
The interest rate would be 23%.

A set of data is summarized by the stem and leaf plot below.
Andre45 [30]

Answer:

30 values ; greater than or equal to 10 and less Than or equal to 39

Step-by-step explanation:

Counting the number of leaves in the plot, we have 30 leaf values. This gives the number of dataset.

The minimum value is the number created by the combination of the least stem value and the lowest leaf value, which is 10

The maximum value is obtained from the combination of the highest stem and leaf value. The highest value is 39

Can anyone help with pre- alerba
faust18 [17]

Answer:

\sqrt{x^2} = |x|

Step-by-step explanation:

\sqrt{x^2} = |x|

The radical symbol when used for a square root means the non-negative  square root. You cannot state that sqrt(x^2) = x because x may be negative. That is why you need use the absolute value symbol.
