Answer:
v=26.41 m/s
Step-by-step explanation:
From the Newtons laws of motions, we sew that x= (2v₁²sin∅os∅)/g where x is the horizontal distance v is the initial speed and ∅ is the launch angle.
From trigonometry we see that 2 sin∅cos∅=sin 2∅
Therefore, x=(v²sin2∅)/g
x=22m
∅=9°
g=9.8m/s²
22m=v²×sin(2×9)/(9.8m/s²)
v²=(22×9.8)/(sin 18)
v²=697.696
v=√697.696
v=26.41 m/s
Answer: After 8 hours the pressure will be at -60?
Explanation: not sure how the balloon can reach -60 kilopascals but 15% of 300 is 45 and 45 x 8(hours) is 360. 300 - 360 is -60

Solve for P which means we have to make 'p' alone
Answer:
(0,-7)
Step-by-step explanation:
In this question, we need to find an ordered pair of (x,y)
First we need to solve the equation for Y. It will be:
y-3=5(x-2)
y=5x-10 +3
y= 5x -7
Then, using the equation you can find the value of y using the value of x. If x= 0 the calculation will be
y= 5x-7
y= 5(0) - 7
y=-7
The ordered pair will be: (0,-7)
Answer:
19
Step-by-step explanation:
1st you will use a^2+b^2=c^2
next you plug them in so it would be a^2+16^2=25^2
next you would solve it to a^2+256=625
then you would get 369 and square root it
and your answer will be 19.2.
