Suatu zarah bergerak sepanjang satu garis lurus melalui suatu titik tetap O. Lajunya, v ms-1 , diberi oleh v = 2t^2 + 9t +16, dengan t ialah masa dalam saat selepas meninggalkan titik tetap O. Cari masa apabila laju ialah 6ms-1.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

what are the
