Shift of 6 units right, reflects over x-axis
Answer:
Step-by-step explanation:
The path covered by the volleyball will be a downward parabola with the vertex being the highest point of the ball.
A general form of a downward parabola is given as:
Where is the vertex of the parabola and 'a' is a constant.
Now, let 'h' be the vertical height and 't' be the time taken.
So, the equation would be of the form:
Now, as per question:
h = 2 seconds, k = 13 feet.
Now, taking a = 1. So, the formula that can be used is:
Let the number of Blue casset be b and that of green be g.
Thus the total number of cassets will be:
b+g=16
hence
g=16-b.......i
The total amount was:
45b+55g=830..ii
plugging i in ii we get:
45b+55(16-b)=830
45b+880-55b=830
simplifying
45b-55b=830-880
-10b=-50
thus
b=5
hence
g=16-5=11
number of blue cassets was 5 and that of green was 11
I will ask my teacher and answer.
Answer:
-12
Step-by-step explanation:
To evaluate the expression the known value of a = -8 can be substituted in so the equation becomes -8 - 4.
From there the subtraction can be completed which equals -12. This can be visually seen on a number line if you look at -8 and move left 4 spaces.
