A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t, where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?
t = 3; It takes the ball 3 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 3; It takes the ball 3 seconds to reach the maximum height and 6 seconds to fall back to the ground.
t = 1.5; It takes the ball 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 1.5; It takes the ball 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.
Answer:
The function is a parabola of the form . The the formula for the axis of symmetry of a parabola is. So it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.
Answer:
D. it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.

The endpoints of directed line segment PQ have coordinates of P (-7, -5) and Q (5, 3). What are the coordinates of point A, on segment PQ, that divide segment PQ into a ratio of 1:3?
Answer:
(2,1)
Step-by-step explanation:
The coordinate point between two points divided between ratio a and b is expressed as;
(X, Y) = [(ax1+bx2/a+b,ay1+by2/a+b]
Given the coordinate points (-7,-5) and (5,3) divided within the ratio 1:3
X = ax1+bx2/a+b
X = 1(-7)+3(5)/1+3
X = -7+15/4
X = 8/4
X = 3
Similarly
Y = ay1+by2/a+b
Y = 1(-5)+3(3)/1+3
Y = -5+9/4
Y = 4/4
Y = 1
Hence the required coordinate point is (2,1)

Which equation represents a line which is perpendicular to the y-axis?
Answer:
The real answer is y=5
Step-by-step explanation:
because its horizontal
y=5 represents a line which is perpendicular to the y-axis
What is Straight line?A line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects
We need to find the equation which represents a line that is perpendicular to the y-axis
A line perpendicular to the y axis will be a horizontal line, the equation of any horizontal line is y=b where b is the y-intercept.
In the given options
x=-6
y=x-4
y=5
and x=-2y
The only horizontal line is y=5
Hence, y=5 represents a line which is perpendicular to the y-axis

rule for translating a point 4 units left and 8 units up.
Write your answer in the space below.
Answer:
this problem has this form, (x,y) (x-7)(y+5) and tells you that the X and Y coordinates are translated to X-7 and Y+5.
Step-by-step explanation:
The translated point A' of the triangle is given by A' ( -3 , 13 )
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
Given data ,
Let the triangle be represented as ΔABC
Now , the coordinates of the triangle are
A ( 7 , 5 ) , B ( 2 , 9 ) and C ( 1 , 3 )
Now , the triangle is translated 4 units left and 8 units up
To translate the point A(7,5) 4 units to the left and 8 units up, we subtract 4 from the x-coordinate and add 8 to the y-coordinate:
A'(3,13)
To reflect this point across the y-axis, we change the sign of the x-coordinate:
A'(-3,13)
Hence , the translated point is A' ( -3 , 13 )

THX AND 5 starts ILL ALSO FRIEND U
U ONLY HAVE TO DO 2 BUT IF U DO BOTH I WILL BE SO GRATEFULL TYSM
Answer:
Solution is positive and both are correct
Step-by-step explanation:
1) since negative times negative is positive and -27 and -35 are both negative then x needs to be positive
2) since positive divided by positive is positive and negative divided by negative is also positive (when the negative sign is in the middle of both numbers on a fraction bar it means both are negative) then both are correct

Answer:
V = 408 SA = 378
Step-by-step explanation:
To find the volume, you need to first find out the area and multiply it by overall length.
A = 1/2 (6)(8)
= 24
Volume = 24 x 17
= 408
Surface Area
SA = Front and Back + Right Side + Left Side + Bottom
= 2 [1/2 (6) (8)] + (17 x 10) + (3 x 8) + (17 x 8)
= 2 (24) + 170 + 24 + 136
= 48 + 170 + 24 + 136
