Answer 1

1. There is a rule to figure out if the graph is narrow, wide or normal:

|a|>1 : Narrow
|a|=1 : Normal
0<|a|<1 : Wide

Using these rules/formulas, we can figure out which quad has the narrowest graph.
A: |-2|=2=Narrower
B: |-3|=3=Narrower (Narrower than option A)
C: |1/3|=1/3=Wide
D:|1/8|=1/8=Wide (Wider than option C)
Your answer to question 1 is B.

2. In this question, you need to look at many things about the triangle.
The triangle is:
-An isosceles triangle
-A right triangle
-Area that equals 53 sq in.
Therefore, one of the formulas you will need is the 45-45-90 Formula, which is l,l,l√2
Another formula you will use is the area of a triangle formula, which is (bh)/2.

First, we need to find the value of bh, which is also x*x.
$\frac{bh}{2} = 53 \\ bh=106 \\ bh=x*x=x^2 \\ x^2=106 \\ x= \sqrt{106}$

You have to take the positive root as this is a scalar quantity. The value of √106 equals approximately 10.3.

You answer for question 2 is A.

I hope this helped you. Let me know if you need more help.
