Suppose that F(t) is a continuous function with known values listed in the table below.
t −1 −0.4 0.2 0.8 1.4 2
F(t) 6.1 4.7 7.3 ___8.1 7.9
Fill in a value for F(0.8) in the blank provided that would guarantee that the equation
F(t) = 6.5 has at least 3 solutions in the interval [−1, 2].

Write the expression as a constant , a single trigonometric function, or a power of a trigonometric function. sin x cos x/ tan x

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
