Which expression is equivalent to (1-sin^2x)(sec x)

1 answer:

8 0

(1-sin²x)(sec x)

(1-sin²x) = cos²x (since sin²x +cos²x = 1)

(sec x) = 1/cosx

(cos²x) . (1/cosx) ==>(cos²x)/cosx) ==> ===> cosx

ehidna [41]

Ok so if we have five dollars per shirt, and if the number of shirts we buy is x, we have 5x dollars for the price. there is also a $40 design fee, so that adds 40. we do not need to pay 40 for every shirt, just once for the whole group, so we have 5x+40 as our answer

3y + 8 = ½ y + 28 Find y

Bess [88]

$\text{Hi there! :]}$

$\large\boxed{y = 8}$

$3y + 8 = 1/2y + 28\\\\\text{Subtract 8 from both sides:}\\\\3y + 8 - 8 = 1/2y + 28 - 8\\\\3y = 1/2y + 20\\\\\text{Subtract 1/2y from both sides:}\\\\3y - 1/2y = 1/2y - 1/2y+ 20\\ \\\text{Convert 3y to 6/2y to make subtracting easier:}\\5/2y = 20\\\\\text{Divide both sides by 5/2 (Multiply by reciprocal, or 2/5):}\\\\\\5/2y * 2/5 = 20 * 2/ 5\\\\y = 8$

(b)<br> Using the formula 2T = M + 3K, find the value of K when T = 11 and M = 4.

Sunny_sXe [5.5K]

Answer:

K = 6

Step-by-step explanation:

Plug in what the letter equals to

Equation will look like:

2(11) = 4 + 3k or 3k + 4 = 2(11)

multiple the 2 by 11 and get 22

3k + 4 = 22 subtract the 4 so it can leave the 3k alone

22 - 4 = 18 now divide 3 from k and do it in the other side

18/3 = 6

so K = 6
