A curve with polar equation
r = I9 / 4sinθ+2Icosθrepresents a line. This line has a Cartesian equation of the form
y = mx+b ,where m and b are constants. Give the formula
for y in terms of x. For example, if the line had equation
y = 2x+3 then the answer would be 2 ∗ x+3.

For the following geometric sequence, find the recursive formula. {-80, 20, -5, } i need : ')

If you can solve all of these i will give ! - 4% of 190 - 4% of 162.5 - 4% of 140 - a 4% increase from 155.1 - a 4% increase from 159.8

Talia took the bus from her home to the bank and then walked back to her home along the same route. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. to determine the time, x, that it took talia to walk home, she used the equation 40(0.9 – x) = 5x. the time of trip 2 is hours. the distance of trip 1 is km.
