A physics student stands at the top of a hill that has an elevation of 56 meters. He throws a rock and it goes up into the air a

nd then falls back past him and lands on the ground below. The path of the rock can be modeled by the equation y=-0.04x^2+1.3x+56 where x is the horizontal distance, in meters, from the starting point on the top of the hill and y is the height, in meters, of the rock above the ground.
How far horizontally from it's starting point will the rock land? Round your answer to the nearest hundredth.

A. 56.00m
B. 24.54m
C. 57.04m
D. 57.26m

Plz help i just started pretty confused
Elina [12.6K]

Answer:

right

neither

straight

neither

Step-by-step explanation:

The first angle is a right angle.  The box in the corner indicates a 90 degree angle

The second angle is less than 90 degrees so it is an acute angle

The third angle is a straight line so it is a straight angle.

The fourth angle is wider than 90 degrees  it is an obtuse angle

Please help I don't understand

17) The line that is John is closer to certain but not exactly on certain so I'd say it's "likely"

18) Using that same example as the one above, if 0 means impossible, then 1 means certain. I'd place your label for Sara at 1. 

19) Let s = sides of the square. There are 4 sides and all sides are equal so we can set up the equation 4s = 64. Divide both sides by 4. s =  16. Now add 2 to this. 16 + 2 = 18. The length of each side of the original square was 18.

20) If the scale is 1 cm : 1 meter and the height of the model is 16 cm, then the actual plane must be 16 meters. 

21) 2x and 100 are supplementary angles meaning together they must add up to 180.

2x + 100 = 180
2x = 180 - 100
2x = 80
Divide both sides by 2
x = 40

22) Assuming 3x is supposed to be the right angle, right angles are 90 degrees. 

3x = 90
Divide by 3 on both sides
x = 30.

Answer:

Step-by-step explanation:

6. Use PEMDAS

-3 x (7 + (-3)*2) / 3

-3 x (7 + 9) / 3

-3 x 16 / 3

-48 / 3

-16

7. 9 (x) = -63

X = - 63 /9

X = -7
