25 (you have to solve both part a and part b) part a: my friend sets out walking at a speed of 3 miles per hour. i set out behind her 5 minutes later at 4 miles per hour. when i start walking, how many miles has my friend traveled? part b: my friend sets out walking at a speed of 3 miles per hour. i set out behind her 5 minutes later at 4 miles per hour. for how many minutes will my friend have been walking when i catch up to her?

up

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
