Write the ratios for sin C, cos C, and tan C.
rosijanka [135]

Answer:

sin C = 7/25

cos C = 24/25

tan C = 7/24

Step-by-step explanation:

opposite of C = 7

adjacent of C = 24

hypotenuse of C = 25

sin = opposite / hypotenuse

so sin C = 7/25

cos C = adjacent / hypotenuse

so cos C = 24/25

tan = opposite / adjacent

so tan C = 7/24

1<br> 1. For f(x) =<br> x²-3<br> find:<br> (a) f(3) (3 points)<br> (b) f(2+h) (3 points)<br> Answer:
Irina18 [472]

Answer:

f(x) = 1/ x² - 3

f(3) = 1 / 3²- 3

=1/6

f(2+h) = 1 / (2+ h) ² - 3

= 1 / 4 + 4h + h² - 3

therefore...

f(2 + h) = 1 / 1 + 4h + h²
