For this case we have the following equations:
We must find 
By definition of composition of functions we have to:
So:
We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined. That is to say:
Then, the domain is given by [3, ∞)
Answer:
The smallest number that is the domain of the composite function is 3
(5/2)(3/10)=(5*3)/(2*10)=15/20=3/4
Or
(5/2)(3/10)= (5)(1/2)(3)(1/10)=(5)(3)(1/2)(1/10) =(5*3)/(2*10)=15/20=3/4
Or
(5/2)(3/10)=(5)(0.5)(3)(0.1)=(2.5)(3)(0.1)=(7.5)(0.1)=.75=3/4
All of these work, but the first one is simplest
Answer:
p equals two and four tenths
Step-by-step explanation:
First let's write our equation
five p plus three equals fifteen
<h3>Subtract three from both sides</h3><h3 />
five p equals twelve
divide both sides by 5
p equals two and four tenths

Step-by-step explanation:
Answer:
52.2
Step-by-step explanation:
Light reflects off a mirror at the same angle it hits it at (as shown in the image). Since both triangles are right triangles, we can say they are similar by AA similarity.
Since they're similar, we can write a proportion.
HT / TV = JS / SV
Plugging in values:
5.8 / 4 = JS / 36
JS = 52.2
The wall is 52.2 feet tall.
