PLEASE HELP!! Two line-segments are tangent to a circle and intersect at point p. Find the value of x.

If 1 is divided by the sum of y& 4.the result is equal to 3 divided by 4, find the value of m

What is the y intercept of f(x)=(1/2)^x?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
