Here, t represents time, which is the input of the function, so we know that 10 is the time in minutes.
h(t) represents the altitude, which is the output of the function after time, t.

On simplifying 210 -15(10), we get that 60 is the altitude in feet. So, after 10 minutes, the hot air balloon is at 60 feet.

Answer:

100

Step-by-step explanation:

$8.(33) * \sqrt{144} = 8.(3) + \sqrt{144} = 8 \frac{1}{3} * 12 = \frac{25}{3} * 12 = 25 * 4 = 100$

Step-by-step explanation:

$4 \\ {x}^{2} = {16}^{2} + {14}^{2} \\ {x}^{2} = 256 + 196 \\ {x}^{2} = 452 = 2 \sqrt{113} = 21.26$

$5 \\ {x}^{2} = {8}^{2} + {15}^{2} \\ {x}^{2} = 64 + 225 \\ {x}^{2} = 289 \\ x = 17$

I believe b because it would be dotted and has a slope of 2 or 2/1
