Mason throws a ball straight up into the air with an initial velocity of 12m/s2 12 m / s 2 . If the point at which Mason released the ball from his hand was 1.25 meters above the ground is modeled by the equation h(t) = −4.9t2+12t+1.25 h ( t ) = - 4 . 9 t 2 + 12 t + 1 . 25 , how long will the ball be in the air for rounded to the nearest tenth?

How many real and imaginary solutions does the equation x^2-3x=-2x-7 have?

Yuto and hila attempted to solve the same inequality. their work is shown below. which statement is true about the work shown above? yuto is correct because he isolated the variable correctly and reversed the inequality symbol. yuto is incorrect because he should not have reversed the inequality symbol. hila is correct because she isolated the variable correctly and reversed the inequality symbol. hila is incorrect because she should not have reversed the inequality symbol.

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
