Find the secant of angle z
a.4/5
b.4/3
c.3/5
d.5/3

D 5/3

Step-by-step explanation:

Secθ= Hypotenuse/Adjacent

Secθ=10/6

Simplify: 10/6 -->5/3

Ans: D 5/3

remember your six trigonometric functions:

Sinθ=Opp/Hyp -->Cscθ=Adj/Hyp

Cosθ=Adj/Hyp -->Secθ=Hyp/Adj

Tanθ=Opp/Adj-->Cotθ=Opp?Adj

It is basically the opposite of each other, don't forget when you are at the last step you simplify! never forget. Also working with square roots will be a bit tricky when converting to Csc/ Sec/ Cot. Just noting you that Square roots don't belong in denominators!

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
