Step-by-step explanation:
SinA=1/3=p/h
p=1,h=3,and b=?
Using Pythagoras Theorem,
b=√3^2-1^2
b=√9-1
b=√8=2√2
Now,
CosA=b/h=2√2/3
TanA=p/b=1/2√2
There is no phi in my keypad so I use A angle instead of phi.Adjust it.

<h3>
Answer: The vertex is located at (2, 2)</h3>
====================================================
Explanation:
The general vertex form is
y = a(x-h)^2 + k
When we compare the function your teacher gave you to this template, then we see that
The vertex is therefore (h,k) = (2,2)
The value of 'a' has no role in the vertex's location. This value determines how vertically stretched or compressed the parabola will be. Also, it determines if the parabola opens upward or downward (a > 0 for upward; a < 0 for downward).
The page count will be 10 when the two students will reach the same count.
Step-by-step explanation:
Given,
Typing speed of Annie = 3 pages per hour
Pages already typed by Annie = 4
Let,
x be the number of hours.
y be the total pages typed.
y = 3x+4 Eqn 1
Typing speed of Whitney = 1 page per hour
Pages already types by Whitney = 8
y = 1x+8 Eqn 2
For same number of pages;
Eqn 1 = Eqn 2
Dividing both sides by 2
Putting x=2 in Eqn 1
Putting x=2 in Eqn 2
The page count will be 10 when the two students will reach the same count.
