A ) This is a quadratic function:
y = a x² + b x + c
If the starting point is ( 0, 0 ) then c = 0
b ) The function is:
y = - 0.2 x² + 3.6 x
( with coefficients to the nearest tenth )
The graph is in the attachment.
c ) The roots:
x 1 = 0,
0.2 x = 3.6
x = 3.6 : 0.2
x 2 = 18d ) This is near the target ( 17 m ) . So the pumpkin
will hit near the target.
For this problem, it is best to draw a plane showing the positive and negative, in x and y axes.
Since it is given that the coordinates of the epicenter is at (0,0), thus it is at the center of the plane.
In order to find the outside boundary of the earthquake, the center-radius equation can be used as follows:
[(x-h)^2] - [(y-k)^2] = r^2
where, (h,k) is the coordinates of the center, which is (0,0), and r is the radius which is equal to 52.
Substituting these values into the standard center-radius equation,
x^2 - y^2 = 52^2
The answer is,
x^2 - y^2 = 2704
Answer: 2 1/2
Step-by-step explanation:
if you have 3 groups of 2 apples and the goal was to have 5, 2 groups would make 4 apples, then you would only need half of a group to make 5 since half of 2 is 1
Answer:
First Choice
Step-by-step explanation:
Domain: (-oo,oo); Range: (-oo,oo)
First of all, you have to manipulate the equation into the standard
form. You can simplify the 1's on both sides and you have
This means that your coefficients are
And since the solving formula is
Plugging your values yields
