Answer:
B
Step-by-step explanation:
Given the function ![h(t)=(t+3)^2+5.](https://tex.z-dn.net/?f=h%28t%29%3D%28t%2B3%29%5E2%2B5.)
Find the average rate of change on interval ![[t_1,t_2]:](https://tex.z-dn.net/?f=%5Bt_1%2Ct_2%5D%3A)
![\dfrac{h(t_2)-h(t_1)}{t_2-t_1}=\\ \\=\dfrac{((t_2+3)^2+5)-((t_1+3)^2+5)}{t_2-t_1}=\\ \\=\dfrac{(t_2^2+6t_2+9+5)-(t_1^2+6t_1+9+5)}{t_2-t_1}=\\ \\=\dfrac{t_2^2-t_1^2+6t_2-6t_1}{t_2-t_1}=\\ \\=\dfrac{(t_2-t_1)(t_2+t_1)+6(t_2-t_1)}{t_2-t_1}=\\ \\=\dfrac{(t_2-t_1)(t_2+t_1+6)}{t_2-t_1}=\\ \\=t_2+t_1+6](https://tex.z-dn.net/?f=%5Cdfrac%7Bh%28t_2%29-h%28t_1%29%7D%7Bt_2-t_1%7D%3D%5C%5C%20%5C%5C%3D%5Cdfrac%7B%28%28t_2%2B3%29%5E2%2B5%29-%28%28t_1%2B3%29%5E2%2B5%29%7D%7Bt_2-t_1%7D%3D%5C%5C%20%5C%5C%3D%5Cdfrac%7B%28t_2%5E2%2B6t_2%2B9%2B5%29-%28t_1%5E2%2B6t_1%2B9%2B5%29%7D%7Bt_2-t_1%7D%3D%5C%5C%20%5C%5C%3D%5Cdfrac%7Bt_2%5E2-t_1%5E2%2B6t_2-6t_1%7D%7Bt_2-t_1%7D%3D%5C%5C%20%5C%5C%3D%5Cdfrac%7B%28t_2-t_1%29%28t_2%2Bt_1%29%2B6%28t_2-t_1%29%7D%7Bt_2-t_1%7D%3D%5C%5C%20%5C%5C%3D%5Cdfrac%7B%28t_2-t_1%29%28t_2%2Bt_1%2B6%29%7D%7Bt_2-t_1%7D%3D%5C%5C%20%5C%5C%3Dt_2%2Bt_1%2B6)
