Answer: False
Step-by-step explanation:
The base is more than 1, so the function is increasing.
Answer: B.Infinitely many
25 degrees because 90-65=25
Answer:
The maximum volume of space that 1,000 BTUs will cool is 400 cubic foot.
Step-by-step explanation:
Given : A total of 1,000 BTUs are needed to cool a space. If 2.5 BTUs are needed to cool 1 cubic foot of space.
To find : What is the maximum volume of space that 1,000 BTUs will cool?
Solution :
Applying unitary method,
2.5 BTU are needed to cool 1 cubic foot of space.
So, 1 BTU are needed to cool cubic foot of space.
Then,1000 BTU are needed to cool cubic foot of space.
i.e. 1000 BTU are needed to cool 400 cubic foot of space.
Therefore, the maximum volume of space that 1,000 BTUs will cool is 400 cubic foot.
It would be -2z+8. Because 3z+-5 is -2 and 2+6 is 8.
