A country's population in 1995 was 164 million. in 2001 it was 169 million. estimate the population in 2015 using the exponentia

Vaselesa [24]

1995. 164 million
2001. 169 million
t = 2001 - 1995 = 6
169 = $164 * p^{6}$
$p^{6} = \frac{169}{164}= 1.0304878 \\ p = \sqrt[6]{1.0304878}$
p = 1.00502
t 1 = 2015 - 2001 = 14
f ( t1 ) = $169 * 1.00502^{14}$
f (t1) = 169 * 1.0762 = 181.27
Answer: a country´s population in 2015 will be 181 million.

Consider the following data set:

Komok [63]

Answer:

+5 Range; The range is now 25

Step-by-step explanation:

The original range would be calculated by subtracting 20 from 40, giving you 20 as the range. However, with the point 15 added, there would be a new lowest number, making the new range be 40-15, which is 25.

A projectile is launched into the air. The function h(t) = –16t2 + 32t + 128 gives the height, h, in feet, of the projectile t s

Zinaida [17]

Answer:

t = 4 seconds

Step-by-step explanation:

The height of the projectile after it is launched is given by the function :

$h(t)=-16t^2+32t+128$

t is time in seconds

We need to find after how many seconds will the projectile land back on the ground. When it land, h(t)=0

So,

$-16t^2+32t+128=0$

The above is a quadratic equation. It can be solved by the formula as follows :

$t=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}$

Here, a = -16, b = 32 and c = 128

$t=\dfrac{-32\pm \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}\\\\t=\dfrac{-32+ \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}, \dfrac{-32\- \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}\\\\t=-2\ s\ \text{and}\ 4\ s$

Neglecting negative value, the projectile will land after 4 seconds.
