Usually, the function of a parabola is y=ax^2+bx+c. With your three given points, which I don't know, plug in your x's and y's to come up with three quadratic equations. Using those equations, you use algebra to find out what a, b, and c equal. Once you have a numerical answer, insert them in the usual quadratic function to have your answer.

Answer:
1) a) yes
b) no
c) a² - 39
(a)² - (sqrt(39))²
(a - sqrt(39))(a + sqrt(39))
This quadratic can be split into real factors, but not rational
sqrt(39) is a real number, but not rational
Answer:
Step-by-step explanation:
Angle corresponds to the complement of the in the bigger triangle. See diagram in attachment.
This implies that,
Also since the triangles are similar, the sides are in the same proportion.
This implies that,
We multiply both sides by 15 to get,
We divide through by 3 to get,
The correct answer is D
Using simple interest, it is found that Devin will pay $60,125 altogether.
The amount paid in <u>simple interest</u> is:
In which:
- P is the principal.
- r is the interest rate, as a decimal.
- t is the time, in years.
In this problem:
- Owes $26,000 in student loans, thus
- Interest rate of 8.75%, thus
- Paid off in 15 years, thus .
The amount he will pay is of:
Devin will pay $60,125 altogether.

Answer:
a) 40320
b) 0.125
Step-by-step explanation:
There are total 8 ingredients
a) The Total Number of ways in which all ingredients can be added randomly = 8*7*6*5*4*3*2*1 = 8! = 40320
b) The probability that the first ingredient that you add is crushed tomatoes = (1*7*6*5*4*3*2*1)/8! = 1/8 = 0.125
