Choose the correct number in which 5 has a value of 5 tenths *

Darya [45]

Step-by-step explanation:

I am thinking that the question means that there is a 5 one place to the right of the decimal. If this is correct then the answer is 67.596. One place to the right of the decimal is the tenths place.

Answer: 56.596

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is $y = 5sin3x$

Step-by-step explanation:

From the question we are told that

$y = c_1\ cos3x + c_2 \ sin 3x$

given that y(0) = 0

We have that

$c_1\ cos3(0) + c_2 \ sin 3(0) = 0$

=> $c_1 = 0$

This means that

$y = c_2 \ sin 3x$

We also given that

$y[\frac{\pi}{6} ] = 5$

$c_2 sin (3 * \frac{\pi}{6} ) = 5$

=> $c_2 = 5$

Hence

$y = 5sin3x$

The proof for the product property of logarithms requires simplifying the expression logb(bx y) to x y. Which property is used t

masya89 [10]

You can use the properties of logarithm to derive the simplified form of the given expression.

The simplification of the given expression requires the given below properties of logarithm

$log_a(b^c) = c \times log_a(b)\\\\$
$log_b(b) = 1$

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

$a^b = c$

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

$b = log_a(c)$

Some properties of logarithm are:

$log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})\\\\log_a(b^c) = c \times log_a(b)\\\\log_b(b) = 1$
