Kruka [31]

Answer:

x = log(33)/(3·log(2))

Step-by-step explanation:

The relevant logarithm relation is ...

log(a^b) = b·log(a)

Taking the logarithm of both sides of your equation gives ...

2^(3x) = 33

log(2^(3x)) = log(33)

(3x)·log(2) = log(33)

The coefficient of x is 3·log(2). Dividing by that gives the value of x:

x = log(33)/(3·log(2))

x ≈ 1.51851/(3·0.301030) ≈ 1.6814647

At the end of April, Mandy told Bill that she has read 16 books this year and reads 2 books each month. Bill wants to catch up t

Dovator [93]

we know that

In an Arithmetic Sequence the difference between one term and the next is a constant

$an=a1+d*(n-1)$

where

a1 is the first term

d is the common difference between terms

n is the number of months (in this problem)

case a) Mandy

$a1=16 books$

$d=2$

$an=16+2*(n-1)$ ------> equation $1$

in this equation the first month is April

case b) Bill

$a1=4 books$

$d=4$

$an=4+4*(n-1)$ -------> equation $2$

In this equation the first month is May

With the equation $1$ and the equation $2$

calculate the attached table

therefore

the answer is

December
