Supplementary angles are angles that add up to 180 so it would probably be 2 and 3 because the highway is 180°

A diver jumps up and over from a cliff in order to avoid rocks and land in the deeper water. The path of the dive can be modeled
lions [1.4K]

Answer:

48.06  to the nearest hundredth.

Step-by-step explanation:

f(x) = -16x^2 + 2x + 48

To find the maximum height we convert to vertex form:

= -16(x^2 + 1/8x) + 48

= -16[x + 1/16)^2 - 1/256] + 48

= -16(x + 1.16)^2  + 16/256 + 48

= 48.0625.

If f(x) = x^2 - 2x+3 <br> then what is f(-3)?
galben [10]

Answer:

f(- 3) = 18

Step-by-step explanation:

To evaluate f(- 3) substitute x = - 3 into f(x)

f(- 3) = (- 3)² - 2(- 3) + 3 = 9 + 6 + 3 = 18

Round 17.641 to the nearest whole number
vfiekz [6]
The nearest whole number would be 18 because the 6 is greater than 5. Anything greater than five, would most likely be rounded to the nearest whole number. Hope this helped!
