now, we know 7 of those angles are already 835°, so the last one must be 1080 - 835 = 245°.
Which graph could represent a constant blalance in a bank account?
2 answers:
<h2>Answer:</h2>
The third graph ( i.e. a horizontal line ) represents a constant balance in a bank account.
<h2>Step-by-step explanation:</h2>Constant balance in a bank amount means that the amount of balance in the account is same over different time period.
i.e. it did not increase or decrease over a period of time.
Hence, the graph of such a situation is a horizontal line parallel to the axis labeled as Time period.

Answer:
<em>a</em> = -10 and <em>b</em> = 18.
Step-by-step explanation:
Let <em>w</em> represent the width of the rectangle.
We are given that the perimeter of the rectangle is 20 cm, this means that:
Let's put <em>w</em> in terms of <em>x</em>. Divide both sides by two:
And solve for <em>w:</em>
<em /><em />
So, the rectangle measures <em>x</em> by (10 -<em> x</em>) cm.
<em />
According to the Pythagorean Theorem:
<em>a</em> and <em>b</em> are the legs and <em>c</em> is the hypotenuse.
Substitute <em>x</em> for <em>a, w</em> for <em>b</em>, and 8 for <em>c:</em>
<em /><em />
Simplify and substitute:
Square:
Isolate the equation. So:
Since the leading coefficient is one, divide both sides by two:
Therefore, <em>a</em> = -10 and <em>b</em> = 18.
