Answer:

x = 12.3

y = 15.9

Step-by-step explanation:

Apply trigonometric ratio to find x and Reference angle = 51°

Opposite side length = x

Adjacent side length = 10

Hypotensive length = y

✔️To find x, apply TOA:

Tan 51° = Opp/Adj

Tan 51° = x/10

x = Tan 51° × 10

x = 12.3 (nearest tenth)

✔️To find y, apply CAH:

Cos 51° = Adj/Hyp

Cos 51° = 10/y

y × Cos 51° = 10

Divide both sides by Cos 51

y = 10/Cos 51

y = 15.9 (nearest tenth)

Which expressions are equivalent to the one below? Check all that apply.<br> 36x/6x

KonstantinChe [14]

For this case we must indicate expressions equivalent to:

$\frac {36 ^ x} {6 ^ x}$

We have to:

$36 ^ x = (6 ^ 2) ^ x = 6 ^ {2x}$

Rewriting the expression:

$\frac {6 ^ {2x}} {6 ^ x}$

To divide powers of the same base, we place the same base and subtract the exponents:

$6 ^ {2x-x} = 6 ^ x$

The options are:

A) $\frac {6 ^ {x} * 6 ^{ x}} {6^{x}}$

B) 6

C) $(\frac {36} {6}) ^ x$

D) $(36-6) ^ x$

E) $6 ^ x$

F) $36 ^ x$

So if we simplify option A) we have: $6 ^ x$

Option C) we have: $6 ^ x$

Option E) is $6 ^ x$

Answer:

Option A, C, E

What is 0.41 divided by 3.69

Ratling [72]

$0.41:3.69= \frac{0.41}{3.69} = \frac{0.41\cdot100}{3.69\cdot100} =\frac{41}{369} =\frac{41}{41\cdot9}=\frac{1}{9}$
