I'm too late but here ya go anyway :)
x = 180 - (31 + 40) is the answer.
Answer:
64
Step-by-step explanation:
<em>[using calculus] </em>When the function h(t) reaches its maximum value, its first derivative will be equal to zero (the first derivative represents velocity of the ball, which is instantaneously zero). We have 
, which equals zero when 
. The ball therefore reaches its maximum height when t = 1.5. To find the maximum height, we need to find h(1.5), which is 64 feet.
<em>[without calculus] </em>This is a quadratic function, so its maximum value will occur at its vertex. The formula for the x-coordinate of the vertex is -b/2a, so the maximum value occurs when t = -48/(2*16), which is 1.5. The maximum height is h(1.5), which is 64 feet.
Answer:
60
Step-by-step explanation:
The yellow and green angles form a right angle, so the measures of those combined will be 90 degrees.
90 - 30 = 60
Answer:
0
Step-by-step explanation:
–5(3 – q) + 4 = 5q – 11
-15 +5q + 4 = 5q -11
-11 + 5q = 5q - 11
+5q - 5q = -11 + 11
0=0
Answer:
K=13,5
y=13,5x, x=numbers of hours
Step-by-step explanation:
To find the proporcionality constant, divide the number of milles traveled in given time.
K=54/4=67,5/5=81/6=13.5 and the equation that describes the relationship is y=13,5x
