What if I send 12 text messages a day, and my sister texted more messages than me. together, you send a total of about 26 messages per day. How many text messages does she send in a day? write an equation and solve for the unknown value

4. find the geometric mean of 4 and 12. 24 8

What is the missing step in this proof ?

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
