A bird leaves the branch of a tree and flies in a straight line. The height of the bird can be represented by the linear model b=23+8t, where b is the height of the bird in feet and t is the number of seconds since the bird left the branch. Part A
What is the meaning of the 23 in the linear model?

A. When the bird left the branch, its height was 23 feet.

B. The bird's vertical rate of change is 23 feet per second.

C. The bird's horizontal rate of change is 23 feet per second.

D. Eight seconds after the bird left the branch, its height was 23 feet.

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

idk

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
