If the parabola looks like an “n,” your vertex will be a maximum. If the parabola looks like a “u,” the vertex will be a minimum.
Answer: y=2x-1
Step-by-step explanation:
Equation of a line that passes through (a,b) and have slope m is given by :-
[point slope form]
Given, Point = (4,7) , m= 2
Equation in point slope form : 
To write in slope intercept form (y=mx+c) , we need to simplify it

Hence, y=2x-1
Remember that you must change this number so that it is between 1 and 10, and then multiply it by a power of 10.
So first, you have to move the decimal point over 2 places to the right.
Since you are moving to the right, the exponent on ten will be negative; since you moved 2 decimal places, you know the exponent will be -2.
The answer is 6.3 x 10^-2.
Hope this helps!
Answer:
From the given ratio for
we found the values are



Step-by-step explanation:
Given the ratio for 
We have to find the rest of trignometric functions:

can be written as

Comparing equations (1) and (2) we get


Equating the coressponding numerator and denominator respectively
Therefore
and
We can find
