Answer:
y=3-3/2
Step-by-step explanation:
Combine like terms. remember to keep the signs.
5x² - 2x² = 3x²
3x - (-6x) = 3x + 6x = 9x
4 - (-3) = 7
3x² + 9x + 7 = Ax² + Bx + C
9 = B, because 9 is in the B's place
9 is your answer
hope this helps
Answer:
The fourth choice
24.2° and 114.2°
Step-by-step explanation:
Complementary angles add up to 90°
Supplementary angles add up to 180°
*a trick to remember this is to know that C is before S in the alphabet, and 90 is before 180, so Complementary is 90 and Supplementary is 180
Step 1: Find the complementary angle
Take 90° and subtract the give angle to find the angle you would need...
90° - 65.8° = 24.2°
Step 1: Find the supplementary angle
Take 180° and subtract the give angle to find the angle you would need...
180° - 65.8° = 114.2°
Taking the upward direction to be positive, the cannonball's height
in the air at time
is given by

where
is the magnitude of the acceleration due to gravity, 10 m/s^2, and
is the height of the building from which the ball is being thrown.
At the moment the cannonball reaches its maximum height of 30 m, its velocity at that time is 0, so that

Substitute this into the height equation above, and let
, for which we have
:

Solve for
: (units omitted for brevity; we know that
should be given in m)
