Answer:
The answer is, " About 56% of those who prefer baseball are eight graders"
Step by Step Explanation:
Step 1: Turn 56% to a decimal, you get 0.56
Step 2: Multiply 0.56 by 68, the total amount of people who like baseball
Step 3 : you get 38.08 ( Don't mind the extra .08, just round )
Step 4 : You celebrate with a little victory dance!!!!!
Answer:
See below
Step-by-step explanation:
I assume you mean 
The equation is already in vertex form
where
affects how "fat" or "skinny" the parabola is and
is the vertex. Therefore, the vertex is
.
The axis of symmetry is a line where the parabola is cut into two congruent halves. This is defined as
for a parabola with a vertical axis. Hence, the axis of symmetry is
.
The minimum value is the smallest value in the range of the function. In the case of a parabola, the y-coordinate of the vertex is the minimum value. Therefore, the minimum value is
.
The interval where the function is decreasing is 
The interval where the function is increasing is
Answer:
Since there are already 2 angles shown, which are 48 and 90 (indicated by the square in the bigger triangle, we can set up an equation.
48 + 90 + y = 180
138 + y = 180
-138 + 138 + y = 180 - 138
y = 42°
