18kg in the ratio 2:7

fredd [130]

Answer:

Step-by-step explanation:

Let the ratios be 2x and 7x respectively.

Now,

2x + 7x = 18

= 9x = 18

= x = 18/9

= x = 2

Hence, 2x = 2*2 = 4

And, 7x = 7*2 = 14

If the domain of f(n) = -4n - 3 is (-1, 1/4,4}, what is the range?

ahrayia [7]

Answer:

$Range= \{1,-4,-19\}$

Step-by-step explanation:

Given

$f(n) = -4n - 3$

$n = \{-1,1/4,4\}$ --- domain

Required

Determine the range

To do this, we simply substitute the values of n in the given expression

So, we have:

$n = -1$

$f(-1) = -4 * -1 - 3 =4 - 3 = 1$

$n = 1/4$

$f(-1) = -4 * 1/4 - 3 =-1 - 3 = -4$

$n=4$

$f(-1) = -4 * 4 - 3 =-16 - 3 = -19$

Hence, the range is:

$Range= \{1,-4,-19\}$

The table represents an exponential function.

GenaCL600 [577]

Answer:

A. ⅕

Step-by-step explanation:

$\frac{2}{5}$ ÷ 2 = $\frac{2}{5} * \frac{1}{2} = \frac{1}{5}$

$\frac{2}{25}$ ÷ 2/5 = $\frac{2}{25} * \frac{5}{2} = \frac{1}{5}$

$\frac{2}{125}$ ÷ 2/25 = $\frac{2}{125} * \frac{25}{2} = \frac{1}{5}$

Therefore, the multiplicative rate of change of the function would be ⅕
