Please help! My teacher didn't teach us this and idk what to do

A. 112 feet

B. 3 seconds

C. 256 feet

Step-by-step explanation:

The function describes the height of the quarter above the water.

When then

Part A. The quarter was tossed from 112 feet.

Find the vertex of parabola represented by quadratic function d(t):

Hence,

Part B. It will take 3 seconds to reach the maximum height.

Part C. The maximum height is 256 feet

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

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.
