Mathematics
1 answer:
Studentka2010 [4]3 years ago
3 0

Answer:

13 unit

Step-by-step explanation:

By the distance formula,

The distance between two points (x_1,y_1) and (x_2, y_2) is,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Thus, the distance between B(8,-7) and C(-4,-2) is,

BC=\sqrt{(-4-8)^2+(-2+7)^2}

=\sqrt{(-12)^2+(5)^2}

=\sqrt{144+25}

=\sqrt{169}

=13\text{ unit}

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 )

Answer:

  5196 m

Step-by-step explanation:

The difference in elevation is found by subtracting one elevation from the other. Usually, we're interested in the positive difference, so we subtract the smaller number from the larger.

  5040 -(-156) = 5040 +156 = 5196

The difference in elevation is 5196 meters.

Which equation is correctly rewritten to solve for x?
ikadub [295]

Answer:

Option (A)

Step-by-step explanation:

Te given equation is,

-qx + p = r

Toe find the value of x,

By subtracting  p from both the sides of the equation.

-qx + p - q = r - q

-qx = r - q

By dividing the whole equation by (-q),

\frac{-qx}{(-q)}=\frac{r-p}{-q}

x = -\frac{r-p}{q}

x = \frac{p-r}{q}

Therefore, Option (A) will be the answer.
