A family on a month-long holiday trip forgets to turn off electricity. The house uses an average current of 10 A continually. The power supply is 120 V (all root-mean-square values for AC). Find the energy used (GJ) in 30 days.

The probability that an adult possesses a credit card is .70. a researcher selects two adults at random. by assuming the independence, the probability that the first adult possesses a credit card and the second adult does not possess a credit card is:

Which equation is y = -6x2 + 3x + 2 rewritten in vertex form?

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.
