Consider the line y=ax+2 (a is a constant) and the circle (x-3)^2+(y+4)^2-25. determine the values of a such that the line is a tangent to the circle.

i think you substitute y=ax+2 into the circle equation but im not sure what to do afterwards

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
