Answer:
a.2s b.43.6m
Step-by-step explanation:
h(t)=−4.9t2+19.6t+24
24m = inittial possition
-4.9 t2= -1/2 g t2
19.6t= Vo t
as the initial velocity is positive, the ball is thrown up.
the maximum height of the ball is reached when the velocity is 0
V= Vo-gt=19.6m/s-9.8m/s2 t=0
t=19.6/9.8=2s
<u>it takes 2seconds for the ball to reach its maximum height</u>
h(t)=−4.9t2+19.6t+24
h(2)=-19.6m+39.2m+24=43.6m
<u>the maximum height of the ball is 43.6m</u>
Answer:
$323
Step-by-step explanation:
70% of 190 is 133
133 + 190 = 323
Answer:
5x -2y = -10
Step-by-step explanation:
Slope-intercept form of the equation for a line is ...
y = mx + b . . . . where m is the slope and b is the y-intercept.
Using the given numbers, the equation is ...
y = 5/2x + 5
Multiplying by 2 gives ...
2y = 5x + 10
Subtracting 2y+10 puts the equation into standard form, with positive leading coefficient and mutually prime coefficients.
5x - 2y = -10
