So hmmm check the graph below
now.. to find the vertex of any quadratic
so... how long did it take? well, it took
what was the highest point? well, it was
when did he hit the water? well, at y = 0
that is
solve for "t"
-t=9(t-10)
-t=9t-90
90=9t+t
90=10t
90/10=t
9=t
Answer:
Harry earns 26 and Hamish earns 20
Step-by-step explanation:
The computation of the amount earned by each one of them is shown below:
Let us assume the hairy be Y
And, the Hamish be M
It is given that Harry earns a dollar i.e more than 5/4
And, it is $2 less than 7/5
So, the equation would be
y = 1.25m + 1 ...........................(i)
And,
y= 1.4m -2 .............................(ii)
Now equal both the equations
1.25m + 1 = 1.4m - 2
3 = 0.15m
So, m = 20
Now put the values of m in any of the above equation to find out the value of Y
Y = 1.25m + 1
= 1.25 (20) + 1
= 26
-1/3
Use the formula m = y2-y1/ x2 - x1.
Substitute the x and y values and you'll get -1/3
Si it is a linear eqaution
