You would multiply it by 4
4(3x^2 +2 )
12x^2 +8
It is 546.4583333333333, which would simplify to 546.46 if to the hundredths place or 546.5 to the tens place
Answer:
1 = 115°
2 = 115°
3 = 65°
Step-by-step explanation:
P=65, so S (3) =65
360-65-65=230
230/2=115
Q (1) = 115
R (2) = 115
Answer:
Y= -2x +40
Step-by-step explanation:
The given equation is
where h is the height, in feet, of a ball and t is the time, in seconds.
<u>Part a: The height of the ball when t = 2 seconds:</u>
The height of the ball above the ground 2 seconds after it is released can be determined by substituting t= 2 in the equation
, we get;

Simplifying the terms, we get;


Thus, the height of the ball after 2 seconds is 100 feet.
<u>Part b: The height of the ball when t = 4 seconds:</u>
The height of the ball above the ground 4 seconds after it is released can be determined by substituting t = 4 in the equation
, we get;

Simplifying the terms, we get;


Thus, the height of the ball after 4 seconds is 68 feet.
