Answer:
Step-by-step explanation:
h(t) = t² - t + 7
h(3) = 3² - 3 + 7 = 9 - 3 + 7 = <em>13</em>
Answer:
(4/5) = n
Step-by-step explanation:
12 = 15n
divide both sides by 15
(12/15) = n
simplify
(4/5) = n

Answer:
First notice that θ is in quadrant I, where the sine and tangent will also be positive.
Then draw the angle in quadrant I. Drop a perpendicular to the x axis.
Since cosθ= 7/25, label the horizontal leg 7, and the hypotenuse 25; the vertical leg will be 24 by Pythagorean theorem.
Then sinθ=vertical/hypotenuse= 24/25 and tanθ= vertical/horizontal= 24/7
