We can factor
And now we know all the terms involved: substitute every occurrence of xy with 7 and every occurrence of x-y with 5 to have
B 0.05 since the thousandth digit is higher than 5, it needs to be rounded up.
Answer:
y-7=x-4
Step-by-step explanation:
If you change the equation to y=mx+b yout would get Y=x+3 plug in the point (4,7) and you would get 7=4+3
7=7 so that is correct.
The midpoint of the segment with endpoints <span>(10, 6) and (-4, 8) would be
</span>
<span>
</span>
Note: It the given equation the coefficient of must be -16 instead of 16.
Given:
Consider the height of the water balloon over time can be modeled by the function
To find:
The maximum height of the water balloon after it was thrown.
Solution:
We have,
Here, leading coefficient is negative. So, it is a downward parabola and vertex of a downward parabola, is the point of maxima.
If a parabola is , then
Here, . So,
Now, put x=5 in the given equation.
The vertex of the given parabolic equation is (5,450).
Therefore, the maximum height of the balloon is 450 units after 5 units of time.
