15x²y³z÷3xy² simplify

umka21 [38]

Answer:

$5xyz$

Step-by-step explanation:

$\frac{15x^2y^3z}{3xy^2}$

Step 1: Divide the numbers

$\frac{15}{3}=5\\\\=\frac{5x^2y^3z}{xy^2}$

Step 2: Simplify

$\frac{x^2}{x}\\\\= x\\\\=\frac{5xy^3z}{y^2}$

Step 3: Simplify

$\frac{y^3}{y^2} = y\\\\=5xyz$

Therefore, the simplified answer is $=5xyz$

In 2000, an invasive plant species covered 0.2% of an island. for the 5 years that followed, the area covered by the plant tripl

Elden [556K]

Answer:

The statement is correct

see the explanation

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

$y=a(1+r)^x$

where

y is the area covered by the plant in percentage

x is the time in years since 2000

r is the rate of change

a is the initial value

In this problem we have

$r=200\%=200/100=2$

$a=0.2\%$

substitute the values

$y=0.2(1+2)^x$

$y=0.2(3)^x$

In the year 2005

$x=2005-2000=5\ years$

substitute the value of x in the exponential function

$y=0.2(3)^5=48.6\%$

48.6% is about 50%

therefore

The statement is correct
