15)dp/dt=F
m(v-u)/0.41=F
m(2u+u)/0.41= m*a
3u/0.41= 1/a
3/0.41= a/u= -7.31
16)v^2-u^2=-2gh
H(max)= 900/2*1.62= 278m
( 0,0 ) is not the solution of the first inequality y≤x² +x-4 but ( 0,0) is the solution for the second inequality y <x²+2x+1.
<h3>What is inequality?</h3>
The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than, or < ‘less than’
Finding the solution for the inequality is as follows:-
y ≤ x² +x-4 by putting x and y equal to 0.
0 ≤ 0 + 0 -4
0 ≤ - 4
This is incorrect so (0,0) can not be the solution for this inequality.
y < x²+2x+1.
0 < 0 + 0 + 1
0 < 1
This inequality is showing the solution for (0,0)
Therefore ( 0,0 ) is not the solution of the first inequality y≤x² +x-4 but ( 0,0) is the solution for the second inequality y <x²+2x+1.

Answer:
112
Step-by-step explanation:
Since 7 goes into 7 put it down and subtract it’s 0
drop down 8 and only 7 goes into it (now you have 11 at the moment)
you have 1 remaining, drop down the 9, 7 goes in 15 twice, (so it’s 112)
with remainder of 5
Answer:

Step-by-step explanation:
the quadratic formula is:

a= -2, b = -1 and c =-3
Putting values in the formula

So, 
Answer:
x = 32°
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary.
∠ A and ∠ D are consecutive angles, then
131 + 17 + x = 180
148 + x = 180 ( subtract 148 from both sides )
x = 32°
