the units of measurement for the composite function s(w(h)) is . Correct option A) .
<u>Step-by-step explanation:</u>
Here we have , Mary paints wooden signs and sells them at craft fairs. The function s(t) approximates how many signs Mary paints per hour. The function w(h) represents how many hours per week Mary spends painting the wooden signs. We need to find What are the units of measurement for the composite function s(w(h)) . Let's find out:
Basically we have two functions as ,
s(t) : how many signs Mary paints per hour
⇒
w(h) : how many hours per week Mary spends painting the wooden signs
⇒
In function composition, if we have two function f(x) and g(x) then
(f.g)(x) or f(g(x)) means first apply g(), then apply f() i.e. applying function f to the results of function g. So , In s(w(h)) :
⇒
⇒
Therefore , the units of measurement for the composite function s(w(h)) is . Correct option A) .
The answer is 9.
To calculate this, we will use Galileo's square cube law, used to describe the change of the area or the volume of the shape, when their dimensions increase or decrease. The formula used for change of the area is
A₂ - the area after the change,
A₁ - the area before the change,
l₂ - the dimension after the change,
l₁ - the dimension before the change.
It is given:
l₁ = 1 cm
l₂ = 3 cm
Let's use this formula for the mentioned triangle:
Therefore, the area of the triangle was multiplied by 9.
