Answer:
(C) 3 feet
Step-by-step explanation:
We have a function of f(x) here. When Sarina throws the ball, it has been 0 seconds since she threw it.
Since x represents the amount of seconds, we can find the height of the ball (f(x)) by substituting x in as 0.
0 squared is 0, 0 minus zero is 0, and 0+3 = 3, so
Meaning that when Sarina threw the ball, it's height was 3 feet.
Hope this helped!
Answer:
V = 13/2
Step-by-step explanation:
When finding volume you must know the formula on doing so.
<em>Volume = length × width × height</em>
length = 
--> 
width = -->
height = 
--> 
<u>mixed number --> fraction</u>
or 
Step-by-step explanation:
it is the vertex form.
remember, (h, k) is the vertex point.
the vertex being the point of the (quadratic) parabola, where the curve turns around.
depending on the orientation of the parabola (vertex up or vertex down) as defined by the sign of a, this is either the minimum or the maximum of the curve.
so, the first a. is correct.
and so is the second a., as they play an important role when completing the square and hence finishing the transformation.

Answer:
y = 5x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x + 9 ← is in slope- intercept form
with slope m = 5
Parallel lines have equal slopes, thus
y = 5x + c ← is the partial equation
To find c substitute (- 2, - 3) into the partial equation
- 3 = - 10 + c ⇒ c = - 3 + 10 = 7
y = 5x + 7 ← equation of parallel line
