liraira [26]

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.

Find the equation of a line given the point and slope below. Arrange your answer in the form y = mx + b, where b is the constant
Nana76 [90]

Answer:

Step-by-step explanation:

an equation is :  y = 10x+b

calculate b : this line passes by : (7;1) when x =7  y = 1

so : 10(7)+ b=1

b= -69

so : y = 10x-69

Has anyone done Exponential Growth and Decay (in mathematical models with application A) on sos or odysseware and gotten a prefe
Lilit [14]

Answer:

1) 62.5

2) 50

3) 75

4) 100

Step-by-step explanation:

1)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*4=100 days, there will be (1/2)^{4}=1/2^{4}=1/16 of it left.

So, 1000/16=\boxed{62.5}.

2)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*3=75 days, there will be (1/2)^{3}=1/2^{3}=1/8 of it left.

So, 400/8=\boxed{50}

3)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*2=50 days, there will be (1/2)^2=1/2^{2}=1/4 of it left.

So, 300/4=\boxed{75}.

4)

The only answer left is \boxed{100} grams. You can solve it the same way you solved the previous steps.

What is a box plot in maths?
Zolol [24]

Answer:

A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile. A vertical line goes through the box at the median
