3 x 3 - ( (-1)^2 - 2)^2

Start evaluating the one in the most inner bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1 - 2)^2

There is one more bracket, so we do what is in the bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1

Between x and -, we do the x first:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1

Then we do the -:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1
= 8

Since FA || BE, then angle 1 must equal angle 2 since they are corresponding angles along parallel lines where the transverse line cuts.
Thus, if angle 1 is 59, then angle 2 must also be 59 (ie D)

A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 30 ft/s. Its height

Crank

Answer:

a) h = 0.1: $\bar v = -11\,\frac{ft}{s}$ , h = 0.01: $\bar v = -10.1\,\frac{ft}{s}$ , h = 0.001: $\bar v = -10\,\frac{ft}{s}$ , b) The instantaneous velocity of the ball when $t = 2\,s$ is $-10$ feet per second.

Step-by-step explanation:

a) We know that $y = 30\cdot t -10\cdot t^{2}$ describes the position of the ball, measured in feet, in time, measured in seconds, and the average velocity ( $\bar v$ ), measured in feet per second, can be done by means of the following definition:
