A dolphin jumping out of the water follows a path described by h = - (x² - 10x + 16), where h is the vertical height in metres and x metres is the horizontal distance travelled. a) How far horizontally does the dolphin travel out of the water?
b) Does the dolphin ever reach a height of 5 metres above water level? Give reasons.

ok

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
