Answer:
-7 × 10
Step-by-step explanation:
Explanation:
6.3
×
10
5
is the same value as
63
×
10
4
So we have:
63
×
10
4
9
×
10
3
ddd
→
ddd
63
9
×
10
4
10
3
ddddddddd.d
→
ddd
63
9
×
10
If the sum of the digits is exactly divisible by 3 then the actual number is also exactly divisible by 3
→
6
+
3
=
9
so we will divide both top and bottom by 3 to simplify the fraction.
ddddddddd.d
→
ddd
63
÷

<span>The <u>correct answer</u> is:
A) Output = Constant/Input.
Explanation<span>:
Inverse proportion is also called inverse variation. In inverse variation, as one variable increases, the other decreases, but their product stays the same.
Algebraically their product would be represented by the equation
xy=k.
To isolate the output, y, we would divide both sides by x:
xy/x = k/x
y=k/x
In this equation, y is the output, x is the input, and k is called the constant of proportionality.
Based on this, the correct choice is output = constant/input.</span></span>
