From the equation of motion, we know,
Where s= displacement
u= initial velocity
a= gravitational force
t= time
Displacement is 0 since the ball comes back to the same point from where it was thrown.
A = 
since the ball is thrown upwards.
Plug the known values into the equation.
=> 
Solving for u gives :
u= 16.67 m/ sec ....... equation (1)
At maximum height, final velocity i.e v is 0
Time take to reach the top = 
=> 
Solving for s we get
s= 14.16 m

Step-by-step explanation:
Answer:The amount of paint that was sold altogether is 173.36 litres
Step-by-step explanation:
The total amount of paint that the paint shop stocks is 1800 litres.
24% of the paint is white. It means that the amount of white paint would be
24/100 × 1800 = 0.24 × 1800 = 432 litres.
The amount of the remaining paint other than white would be
1800 - 432 = 1368 litres
The shops sells 18% of the white paint. This means that the amount of white paint sold by the shop will be
18/100 × 432 = 0.18 × 432 = 77.6 litres.
The shops sells 7% of the rest of the paint.
This means that the amount of the rest paint sold by the shop will be
7/100 × 1368 = 0.07 × 1368 = 95.76 litres.
The amount of paint that was sold altogether would be
77.6 + 95.76 = 173.36 litres
Answer:
Her oldest was 9, and the other 2 were 2
Answer:
Y= -12x + 150
Step-by-step explanation:
1. You do the change in y over the change in x to get the slope.
y1 - y2 / x1 - x2 and you get the slope of -12
2. Making a point-slope form equation
y-y1=m(x-x1)
y-138= -12(x-1)
3. Turning point-slope form equation to slope-intercept
y-138= -12(x-1)
distributive property
y-138=-12x+12
add 138 on both sides
<h2><u>
y= -12x+150</u></h2>
