Between 1965 and 1980, the world population grew at an annual rate of 2%. Using the rule of 72, population is expected to double
Fiesta28 [93]

Answer:

The population is expected to double in 36 years

Step-by-step explanation:

According to the the rule of 72,

A value is doubled if the product of the annual rate and number of years is 72,

Given,

The annual rate of interest = 2%

Let x be the time in years after 1965,

By the above statement,

The population will double if,

x × 2 = 72 ⇒ x = 36

Hence, the after 36 years since 1965 the population will be doubled,

i.e in 2001.   ( ∵ 36 years after 1965 )

SVEN [57.7K]

Answer:

A <em> </em><em>and</em><em> </em><em>E</em><em> </em><em>is</em><em> </em><em>true</em><em>. </em><em>BCD</em><em> </em><em>is</em><em> </em><em>False</em>

Step-by-step explanation:

Let convert this into slope intercept form

10y - 200x = 500

10y = 200x + 500

y = 20x + 50

So now let answer these questions,

A is TRUE the slope is the number in front of the x value. It is 20 so a is true.

B is False, Using (0, 500) The equation is wrong

500 = 20(0) + 50 ??

C is false, we have a positive slope so it shifts upward from left to right.

D is false

the slope isn't 200.

E Is true the y intercept is when the x value is 0, what is the y value so plug it in we get

y = 20(0) + 50

It equal 50.
