SinA=(7/25), determine CosA and TanA exactly

bixtya [17]

Answer:

Cos A = 24/25 & Tan A = 7/24

Step-by-step explanation:

See the attached figure.

Construct a right triangle and sign one angle as A

So, Sin A = opposite/hypotenuse = 7/25

∴hypotenuse = 25 and opposite = 7

∴ adjacent = √(25² - 7² ) = √576 = 24

∴ Cos A = adjacent/hypotenuse = 24/25

And

Tan A = opposite/adjacent = 7/24

Parallel, intersecting or skew?

const2013 [10]

Two lines are:

Parallel if they don't intersect and lie on the same plane
Intersecting if...well, they intersect at one point
Skew if they don't intersect and they lie on two different planes

So, we have:

AB and BC intersect at point B
AE and BF don't intersect, but both lie on the plane AEFB
EF and AD don't intersect and don't lie on a common plane
ABC and ABF intersect on segment AB
AED and BFC are parallel (they're both perpendicular to plane ABC)

f(x) = 0.5x - money per ticket

g(x) = 8x - tickets per hour

We replace g(x) with its value (8x).

f(g(x)) = f(8x)

We replace the x in f(x) with 8x.

f(8x) = 0,5 × 8x

f(8x) = 4x

⇒ f(g(x)) = 4x

Correct answer:

a. f(g(x)) = 4x, which represents the money Aurora made in dollars per hour
