Answer: 5.14 cu in
Step-by-step explanation:
1/2 (π × d) + d, where d is the diameter of the semi
Perimeter = 1/2 (3.14 x 2) + 2
= 1/2 * 6.28 + 2
= 3.14 + 2
Given:
The fees for a day student are $600 a term.
The fees for a boarding student are $1200 a term.
The school needs at least $720000 a term.
To show:
That the given information can be written as
.
Solution:
Let x be the number of day students and y be the number of boarding students.
The fees for a day student are
a term.
So, the fees for
day students are
a term.
The fees for a boarding student are
a term.
The fees for
boarding student are
a term.
Total fees for
day students and
boarding student is:

The school needs at least $720000 a term. It means, total fees must be greater than or equal to $720000.


Divide both sides by 600.


Hence proved.
Answer:
= - 48
Step-by-step explanation:
-6 * f(3) -6 * g(-1)
= -6 * 2 - 6 * 6
= -12 - 36
= - 48
To find the values of f(3) and g(-1), look for where the x value equals 3 or -1 respectively and match it to the y value that corresponds to on its line.
