Can anyone help me with this

b and c

Step-by-step explanation:

Sine = opp/hyp

Cosine = adj/hyp

Step-by-step explanation:

The answers are c and d.

Since it's only x needed, the 'y' is not to be included since there is no value for it.

To get the first answer, you can start from 25°.

11 is the hypotenuse and x is the adjacent, since the hypotenuse is the longest side and the adjacent has an angle lying on it.

With the use of CAH from the SOH CAH TOA, option c is proven to be correct.

To get the second answer, you can simply change the position of your screen and solve it like that too.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
