=sec(atan(1/sqrt(3)))
=sec(atan(sqrt(3)/3))  .... evaluate atan(sqrt(3)/3), use unit circle
=sec(pi/6)
=1/cos(pi/6)...... evaluate cos(pi/6), use unit circle
=1/(sqrt(3)/2)  
=2/sqrt(3)  .... now rationalize

Volleyballs cost $22.00 each. The Athletic Director has $277.00 in her budget to spend on new volleyballs. There is a $13.00 shi
OLEGan [10]

Answer: The Athletic can other 12  volleyballs.

Step-by-step explanation:

If the director has $277 to spend then it means The director can spend at most $277.

Now one volleyball cost $22 and so we could represent the number of volleyballs you can buy by the expression 22x  and including the shipping fee,we will extend the expression to 22x + 13  Now since the Director can spend  up to $277 or less we can write the whole situation in a form of inequality as,

22x + 13 ≤ 277  Now solve for x to determine the number of volleyballs  

          -13   -13

22x  \leq 264

x \leq 12

Recall that the scores in Mr. Young’s class had a mean of 78 and a standard deviation of 8. About what percent of students score
Molodets [167]

Answer:

B. 34%.

Step-by-step explanation:

94 - 78 = 16 which is 2 times the standard deviation from the mean.

For a normal distribution this is 34% of the total students.

Helppppp please !!!!​
gtnhenbr [62]

Step-by-step explanation:

the extreme values (minimum, maximum) of a function are the zero points of the first derivation of the function.

so,

f'(x) = 2x + b

and then

2x + b = 0

we know, x = 20 for the minimum

2×20 + b = 0

40 + b = 0

b = -40

therefore, the actual function is

f(x) = x² - 40x + 164

the target format is

f(x) = (x - h)² + k = x² - 2hx + h² + k

so,

-40x = -2hx

-40 = -2h

h = 20

and

h² + k = 164

20² + k = 164

400 + k = 164

k = -236
