If log25 ~ 2.3219,
evaluate log280.

Answers

Answer 1

Answer:

You need to write log_2 80 in terms of log_2 5 , such that:

log_2 80 = log_2 (8*10)  

Using the properties of logarithms, you need to convert the logarithm of product in summation of logarithms, such that:

log_2 (8*10)= log_2 8 + log_2 10

Since log_2 10 = log_2 (2*5) , yields:

log_2 (8*10)= log_2 8 + log_2 (2*5)

log_2 (8*10)= log_2 8 + log_2 2 + log_2 5

You need to write 8 as power of 2, such that:

log_2 (8*10) = log_2 (2^3) + log_2 2 + log_2 5

Using the power property of logarithms, log_a b^c = c*log_a b  yields:

log_2 (8*10) = 3log_2 2 + log_2 2 + log_2 5

Since log_2 2 = 1 yields:

log_2 (8*10) = 3 + 1 + 2.3219

log_2 (8*10) = 4 + 2.3219 => log_2 (8*10) = 6.3219

Hence, evaluating the given logarithm , using the indicated properties of logarithms, yields log_2 (8*10) = 6.3219 .

Step-by-step explanation:

Answer 2

The value of [tex]log_2{80}[/tex] if [tex]log_25 = 2.3219[/tex] is 6.3219.

What is a logarithm?

The logarithm is exponentiation's opposite function in mathematics.

This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.

Given, [tex]log_25 = 2.3219[/tex].

Now, To obtain the value of [tex]log_2{80}[/tex] we'll break it into suitable smaller parts.

Therefore,

[tex]log_2{80} = log_2({8\times10})[/tex].

[tex]log_2{80} = log_28 + log_210[/tex]

[tex]log_2{80} = log_28 + log_2({2\times5})[/tex].

[tex]log_2{80} = log_28 + log_22 + log_25[/tex].

[tex]log_2{80} = 3 + 1 + 2.3219[/tex].

[tex]log_2{80} = 6.3219[/tex].

Your grandmother is worried about the heat during the family reunion picnic yesterday between 10 am and noon the temperature rose 6 degrees then between noon and 3pm it rose 4 degrees what was the average rate of increase in temperature between 10am and 3pm

Answers

Answer:

Average rate of temperature increase is 2 degrees per hour

Step-by-step explanation:

Here, we want to calculate the average rate of increase in temperature

From what we have above, we can calculate this by dividing the total temperature rise by the number of hours

The total temperature rise is 6 + 4 = 10 degrees

This means that the temperature rose by 10 degrees between 10 am and 3 pm

The number of hours between 10 am and 3 pm is 5 hours

So the average rate of temperature increase is 10 degrees/ 5 hours = 2 degree per hour

What is the solution to 0.3(12x - 16) = 0.4(12 - 3x)?

Answers

Step-by-step explanation:

The solution is one-solution

.3(12x-16)=.4(12-3x) (you do the distributive property)

3.6x-4.8=4.8-.12x (you add 1.2 to both sides)

3.6x-3.6=4.8 (You add 3.6 to both sides)

3.6x=8.4 ( You divide 3.6 both numbers)

x=0.4285...

Its a one-solution

3 3/4 = r + 1/8

Answer:

r = 29/8 or 3 5/8

Step-by-step explanation:

so you need to make them have the same denominator so you multiply 3/4 by 2/2 to get that

this equals 6/8

add 3 so 24/8

then you subtract 1/8 from both sides

r = 29/8

simplify so 29/8 = 3 5/8

write the equation. the output of a function is 6 more than 2 times the input.

Answers

Answer:

y = 2x+6

Step-by-step explanation:

Let the output value be y

Let the input value be x

the output of a function is 6 more than 2 times the input

2 times the input is expressed as 2x

6 more than 2 times the input is expressed as 2x + 6

Since the output of a function is 6 more than 2 times the input, we will equate y to the resulting equation to have;

y = 2x + 6

Hence the required equation is y = 2x+6
