Answer:
where is the question?
Step-by-step explanation:
Answer:
a) y-intercept is 4000
b)T(18)=5710
Step-by-step explanation:
a) This is the equation of a line with slope 95 and y-intercept 4000.
The y-intercept represents the basic amount the student has to pay even if not taking any unit: $4000
b) T(18) represents the total amount to be paid by a student who is taking 18 units: T(18) = 4000 + 95*18 = 4000 + 1710 = 5710
So a total tuition of $5710
Your answer is option D. √(15² + 19²). This is because the line PQ is the hypotenuse of this right triangle, so you can use the formula a² + b² = c² to find its length, which means it would equal the square root of 15² + 19², which is what option D expresses.
I hope this helps!
