Evaluate 15r -1 when r=5

alukav5142 [94]

Answer:

Step-by-step explanation:

You just have to substitute r with 5.

Now, the equation looks like this:

$15(5)-1$

Next, solve $15*5$ first according to PEMDAS

And $15*5$ equals 75

$\frac{\left[\begin{array}{ccc}1&5\\5\\\end{array}\right] }{75}$

Lastly, do $75-1$ which equals 74

$\frac{\left[\begin{array}{ccc}7&5\\-1\\\end{array}\right] }{74}$

Therefore, 74 is your answer.

Sec={ }

Eduardwww [97]

Answer:

A choice

Step-by-step explanation:

sec is defined as 1/cos.

cos is again defined as adjacent to hypotenuse.

We know that adjacent is x and hypotenuse is r.

Therefore:- cos is x/r

Now sec is 1/cos = 1/(x/r)

1 ÷ x/r is 1•r/x

Thus:-

sec is r/x
