Question help please these are them 3

iren [92.7K]

Answer: 0

Step-by-step explanation:

$log_{m} 1 = x$

1 = mˣ

1 = m⁰

**************************************************************

Answer: $x = -\frac{2}{33}$

Step-by-step explanation:

log₁₀ (1 - 6x) = 2 restriction: 1 - 6x > 0 ⇒ x < $\frac{1}{6}$

1 - 6x = 10²

1 - 6x = 100

-1 -1

-6x = 99

$\frac{-6x}{-6} = \frac{99}{-6}$

x = $-\frac{2}{33}$

**************************************************************

Answer: $x = -\frac{3}{5}$

Step-by-step explanation:

$\frac{1}{\sqrt[5]{27} }$ = 3ˣ

$\frac{1}{\sqrt[5]{3^{3}} }$ = 3ˣ

$\frac{1}{3^{\frac{3}{5} } }$ = 3ˣ

$3^{-\frac{3}{5}$ = 3ˣ

$-\frac{3}{5} = x$

**************************************************************

Answer: $x = \frac{5}{9}$

Step-by-step explanation:

ln 2 + ln x = ln 5 + ln (4x - 2)

ln (2(x)) = ln (5(4x - 2))

2x = 5(4x - 2)

2x = 20x - 10

-20x -20x

-18x = -10

$\frac{-18x}{-18} = \frac{-10}{-18}$

$x = \frac{5}{9}$

The following table shows the estimated populations and annual growth rates for four countries in the year 2000. Find the

gladu [14]

Answer:

Part 1) Australia $19,751,012\ people$

Part 2) China $1,319,645,764\ people$

Part 3) Mexico $109,712,539\ people$

Part 4) Zaire $60,534,681\ people$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$P(t)=a(1+r)^t$

where

P(t) is the population

t is the number of years since year 2000

a is he initial value

r is the rate of change

Part 1) Australia

we have

$a=19,169,000\\r=0.6\%=0.6\100=0.006$

substitute

$P(t)=19,169,000(1+0.006)^t$

$P(t)=19,169,000(1.006)^t$

Find the expected population in 2025,

Find the value of t

t=2005-2000=5 years

substitute the value of t in the equation

$P(5)=19,169,000(1.006)^5=19,751,012\ people$

Part 2) China

we have

$a=1,261,832,000\\r=0.9\%=0.9\100=0.009$

substitute

$P(t)=1,261,832,000(1+0.009)^t$

$P(t)=1,261,832,000(1.009)^t$

Find the expected population in 2025,

Find the value of t

t=2005-2000=5 years

substitute the value of t in the equation

$P(5)=1,261,832,000(1.009)^5=1,319,645,764\ people$

Part 3) Mexico

we have

$a=100,350,000\\r=1.8\%=1.8\100=0.018$

substitute

$P(t)=100,350,000(1+0.018)^t$

$P(t)=100,350,000(1.018)^t$

Find the expected population in 2025,

Find the value of t

t=2005-2000=5 years

substitute the value of t in the equation

$P(5)=100,350,000(1.018)^5=109,712,539\ people$

Part 4) Zaire

we have

$a=51,965,000\\r=3.1\%=3.1\100=0.031$

substitute

$P(t)=51,965,000(1+0.031)^t$

$P(t)=51,965,000(1.031)^t$

Find the expected population in 2025,

Find the value of t

t=2005-2000=5 years

substitute the value of t in the equation

$P(5)=51,965,000(1.031)^5=60,534,681\ people$
