Find a numerical value if one trigonometric function of x if tan2x-sin2x/sin2x=5

seropon [69]

Answer:

The values of x that satisfy the given equation are:

x1 = 1.183 + nπ

x2 = -1.183 + nπ

Step-by-step explanation:

Given tan²x - sin²x/sin²x = 5

Simplifying this, we have

tan²x - 1 = 5

Adding 1 to both sides, we have

tan²x = 6

Because tan²x = (tanx)², we can write as

(tanx)² = 6

Taking square roots of both sides, we have.

tanx = ±√6

x = arctan(±√6) + nπ

≈ 1.183 + nπ or -1.183 + nπ

Can anyone give me a hint or answer this?

RideAnS [48]

Answer:

x=8.5

Step-by-step explanation:

∠AOC=68

∠COD= (2x+5)

∠AOC and ∠COD are complimentary angles. This means that when you add them together you get 90.

∠AOC + ∠COD = 90

68 + (2x+5) =90

2x+5=22

2x=17

x=8.5

Ticket Taker Tony collects 90 tickets in 5 minutes. Ticket Taker Tina collects 128 tickets in 8 minutes. Which ticket taker coll

SpyIntel [72]

Answer:

Ticket Taker Tony collects more tickets per minute.

Step-by-step explanation:

In order to find out which ticket taker collects more tickets per minute, you need to solve for how many tickets each Ticket Taker collects per minute to compare. Since 90:5 and 128:8 are different ratios, you need to find the unit rate, or how many tickets each collects per minute. To find unit rate, you divide the numerator by the denominator:

Ticket Taker Tony: $\frac{90 tickets}{5 minutes}$ = $\frac{18 tickets}{1 minute}$

Ticket Taker Tina: $\frac{128 tickets}{8 minutes}$ = $\frac{16 tickets}{1 minute}$

Every minute, Tony collects 18 tickets, while Tina only collects 16, so Ticket Taker Tony collects more.
