<span>The general equation of a quadratic is expressed as y = ax^2+bx+c. To
convert the general equation to vertex form, we need to obtain this form:
(y- k)= a(x - h)^2
This could be done by using completing the square method.
</span><span>y = –3x^2 – 12x – 2
</span><span>y + 2 = –3(x^2 + 4x)
</span>y + 2 -12 <span>= –3(x^2 + 4x + 4)
</span>y - 10 = -3(x+2)^2
Therefore, the answer is the first option.
Answer:
Exact Form: y = 5/9 | Decimal Form: y = 0.¯5
Step-by-step explanation:
Answer:
$56
Step-by-step explanation:
You first round 49.99 and 29.99 to 50.00 and 30.00. Then you add them together and get 80.00. Now you discount them by 30 and get $56.00.
Hope It's right. Sorry if it's not.
If the grist mill completes the rotation in 8 seconds. Then the final position of the bucket after 6 seconds is (0, 9).
<h3>What is coordinate geometry?</h3>
Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
A water grist mill has a radius of 9ft and takes 8 seconds to make a complete rotation. a bucket starts at position (9,0).
Then the coordinates of the bucket's location after 6 seconds will be
The angle of rotation after 6 seconds will be
Then we have
x = 9 cos 270°
x = 0
and y will be
y = 9 sin 270°
y = -9
But the angle is in a clockwise direction, then
y = 9
