An athlete whose event is the shot put releases a shot. When the shot whose path is shown by the graph to the right is released at an angle of 30°, its height, f(x), in feet, can be modeled by f(x) = -0.01x2 +0.6x + 5.9, where x is the shot's horizontal distance, in feet, from its point of release. Use this model to solve
parts (a) through (C) and verify your answers using the graph.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

12cm

the answer is d

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
