The function f(x)= kx^3 - 8x^2 -x + 3k + 1 has a zero when x=2. determine the value of k. graph f(x) and determine all the zeros. then rewrite in factored form. i found that k=3 so far, but i'm not sure how to graph it without making a table of values, or how to find the zeros. any ideas?

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

If square root x = -7, then x= -49 true or false

It is saturday morning and jeremy has discovered he has a leak coming from the water heater in his attic. since plumbers charge extra to come out on the weekends, jeremy is planning to use buckets to catch the dripping water. he places a bucket under the drip and steps outside to walk the dog. in half an hour the bucket is 1/5 of the way full. what is the rate at which the water is leaking per hour?
