Answer:

A parabola opens downward with vertex at (1,20)

Step-by-step explanation:

The function that models the height of bag of candies is

$h(t) = - 16 {t}^{2} + 32t + 4$

The graph of this function is a parabola that opens downward.

To find the maximum height of the candy bag, we complete the squares to obtain the vertex form of the function.

Factor -16 to get;

$h(t) = - 16( {t}^{2} - 2t) + 4$

Add and subtract the square of half the coefficient of t.

$h(t) = - 16( {t}^{2} - 2t + 1) + 16+ 4$

Factor the perfect square trinomial:

$h(t) = - 16( {t - 1)}^{2} + 20$

The vertex is (1,20)

This means the maximum height after 1 second is 20 feet.

Jin bought a pair of pants that cost $47.83. The sale tax in her state is 7.43 % what is the total cost of the pants ?

maxonik [38]

Answer:

$51.38

Step-by-step explanation:

7.43% of 47.83=(rounded to the nearest hundredth) 3.55

7.43/100*x/47.83

x=3.55

because we are solving for x

we can also cross check by taking out the percentage

x/100*3.55/47.83

47.83x=355

x=7.42212000836

which is about 7.43%

47.83+3.55= 51.38
