Một tam giác vuông có tỉ số hai cạnh góc vuông bằng 3/4, cạnh huyền dài 10cm. Tính độ dài hình chiếu của hai cạnh góc vuông trên cạnh huyền

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.

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
