The table represents an exponential function.

Mathematics
1 answer:
kkurt [141]3 years ago

Answer:

b=2/3

Step-by-step explanation:

The table is given as:

\left|\begin{array}{c|c}x&y\\--&--\\1&9\\2&6\\3&4\\4&\dfrac83\\\\5&\dfrac{16}{9}\end{array}\right|

The exponential function is given in the form

y= a (b)^{x}

where a is the initial value and b is the multiplicative rate of change

When  x=1, y=9, we have:

9= a (b)^{1}

When  x=3, y=4, we have:

4= a (b)^{3}

Dividing the two equations:

\dfrac{a (b)^{3}}{a (b)^{1}} =\dfrac{4}{9} \\b^2=\dfrac{4}{9}\\b=\sqrt{\dfrac{4}{9}} \\b=\dfrac{2}{3}

The multiplicative rate of change, b is 2/3.

What is the median of the following numbers?<br> 6,4, 1,9,3,8,3,5, 10
Sergeu [11.5K]

Median = 5

Mean = 5.4444444444444

Mode: 3

Range = 9

Minimum =   1

Maximum =  10

How to find Median:

Arrange your numbers in numerical order.  Then the second step is to have an odd number, divide by 2 and round up to get the position of the median number.  The last step is to find the even number and if you have it, divide it by 2.

Answer: 5

Hope this helps.

A volleyball player sets the ball in the air, and the height of the ball after t seconds is given in feet by h= -16^2+12t+6. A t
pychu [463]

Answer:

Step-by-step explanation:

The given function is

h=-16t^2+12t+6

The graph of this function is a parabola that opens downwards

The line h(t)=8 intersects this parabola, when

t=0.5,t=0.25

The teammate can spike the ball after 0.25 seconds or 0.5 seconds.

The two solutions are reasonable. When the volleyball is accelerating into the air, it passes a height of 8 after 0.25 seconds.

When the ball is dropping after it attains maximum height, it attains another height of 8 after 0.5 seconds again.

That's the question ?? ​
Oksanka [162]

Step-by-step explanation:

Before we answer, the area of a Circle given it radius is

a = \pi r {}^{2}

The area of a circle given it diameter is

a =  \pi( \frac{d}{2} ) {}^{2}

So let answers question 1-4.

1. The area is

1024\pi

2. The area is

576\pi

3.

1.225\pi

4.

309.76\pi

For the 5th problem, circumference is

\pi \times d

where d is the diameter and

2\pi  r

where r is the radius.

A circumference of 100 m means the radius is 50 because

2\pi \times r = 100\pi

r = 50

So this means the area is

2500 {\pi}
