I assume that by 0 you mean theta.

First you'd need to find the cosine of theta (because secant is the reciprocal of cosine). We can do this with right triangle trig. Sine is opposite over hypotenuse, so draw a right triangle, pick an angle and call it theta, and then lable the opposite side 17 and the hypotenuse 37. You can use the pythagorean theorem to get the measure of the third side.

17² + b² = 37²

289 + b² = 1369

b² = 1080

b = 6*sqrt(30)

The cosine of theta is 6*sqrt(30)/37. Therefore, the secant of theta is 37/6*sqrt(30). Apparently you're not supposed to leave radicals in the denominator of a fraction, so you'd multiply by sqrt(30)/sqrt(30) to get 37*sqrt(30)/6*30, which is 37*sqrt(30)/180.

Your good!!!!!

🤓😂

You make one penny the first day, two pennies the second day, four pennies the third day, eight pennies the fourth day, how many will i mak for 30 days

1+2+4+.......

a=1

r=2

n=30

\(S_n=\frac{a(r^n-1)}{r-1}\\ S_{30}=\frac{1(2^{30}-1)}{2-1}\\ S_{30}=2^{30}-1 \)

2^30-1 = 1 073 741 823 cents =   $10 737 418.23 

Radical form is just simplifying a radical so that there are no more square roots, cube roots, 4th roots, and etc. left to find. It also means removing any radicals in the denominator of a fraction.

I got u

so there is a couple diferent uses

first finding angles

in a triangle (theta is the angle)

if you put the two sides lets label them o and a (or x and y here)

we know that tan = o/a right?

so if we put 

tan^-1(o/a)= theta 

hope it helps 

:P

2 x 1/5  =  (2 * 5)^x

2/5        = 10^x

.2           = 10^x

log(.2) = x log 10

log .2    = x (1)

log .2 = x = - 0.69897

That is for you to decide my friend 

Yes, according to 2014 info, 2.943 million (that is 2.943 x 10^6) people (including YOU), live in Utah.   LOL

320 miles  /  20 miles/gal         x     $1.20 / gal    =        320/20 * 1.20 = $ 19.20

Car value = 22000(1 - .4)^n          n is the number of years    -.4 = 40% decrease each year

2r*9 = 18*r

multiply "r" by 18.

nice boi

10:48 PM to 7:12 am  is   8 hrs 24 min      this assumes you dreamt the 7:14 am time ....

2.8 trillion = 2,800,000,000,000 = 2.8 x 10^12 passwords

30 nanoseconds = .000 000 030 seconds = 3 x 10^(-8)

You can use the calculator to do this    enter  30  divided by 1 000 000 000 then =   and = again ....

Unit rate    miles per minute  =    26/148 = 0.175= 0.176 miles per minute (rounded)

If you want minutes per mile  148/26 = 5.69  min/mile      

Gather 'like' terms

(-6x+3x) + (4y-5y)  - 4 =

-3x + (-y) - 4

-3x - y -4

One variable 'y is already isolated   as  y =x-5    sub this value of y into the second equation to find 'x'

x + y = 9

x + (x-5) = 9

2x -5 = 9

2x = 14

x=7           Now that you have x  :      y= x-5  = 7-5 = 2    x,y = 7,2

6=6/1 so you do the numerators x the denominators which is 6x2/1x3=12/3 then simplify and make into a mixed number so final answer is 4

One leg is given by   10 sqrt3  x sin 30

Other leg is given by  10 sqrt3 x sin 60
