The equation for the speed of a ball that is thrown straight up in the air is given by $v=46-32t$ where *v* is the velocity (feet per second) and *t* is the number of seconds after the ball is thrown. What does the *y*-intercept represent in this context?

A

The *y*-intercept indicates that when the ball was released at *t* = 0, it was thrown upward at 46 feet per second.

B

The *y*-intercept indicates that when the ball was released at *t* = 0, it was thrown upward at 32 feet per second.

C

The *y*-intercept indicates that when the ball was released at *t* = 1, it was thrown upward at 46 feet per second.

D

The *y*-intercept indicates that when the ball was released at *t* = 1, it was dropped from 32 feet.

David works for a computer software company. His first month on the job he had $8,000 in software sales. His sales manager told him he would get a bonus if he increased his sales by 3% in the next month. If his sales manager keeps increasing his goal by 3% per month, how could David figure how much he would need to sell 6 months from now and *n* months after that?

A

The expression $8,000\times 1.{03}^{\left(6n\right)}$ can be used because ${\left(1.{03}^{6}\right)}^{n}=1.{03}^{\left(6n\right)}$.

B

The expression $8,000\times 1.{03}^{\left(6+n\right)}$ can be used because $1.{03}^{6}\times 1.{03}^{n}=1.{03}^{\left(6+n\right)}$.

C

The expression $8,000\times 1.{03}^{\left(6+n\right)}$ can be used because $1.{03}^{6}+1.{03}^{n}=1.{03}^{\left(6+n\right)}$.

D

The expression $8,000\times 1.{03}^{\left(6n\right)}$ can be used because $1.{03}^{6}\times 1.{03}^{n}=1.{03}^{\left(6n\right)}$.
