The practical domain is all real numbers from 4 to 9, inclusive.
The practical range is all real numbers from 49.6 to 111.6, inclusive.
These are the correct options.
Explanation:
Given function is f(t) = 12.4t
Let us assume that Nate works 'x' hours so 4<x<9
And multiplying the hours with his earnings we get the range.
4*12.40=49.6 and 9*12.40=111.6. Let the amount earned be represented by y
Hence, domain can be represented as 4<x<9 and range can be represented as 49.6 < y < 111.6
Answer: 3/8+1/6= 0.541
Step-by-step explanation:
It is a right triangle so,
a² + b² = x²
9² + 12² = x²
225 = x²
√225 = x
15 = x
Hope this helps :)
Answer:
Step-by-step explanation:
trg CDE ,<C=<E=(180-20)/2=80
trg ABC,<C=80
<A=180-(80+52)=180-132=48
so <F=<A=48 grades
