Solve for x. Evaluate and round your answer to 1 decimal place(tenths place). 10x=1200
Mandarinka [93]

Answer:

<h2>x = 3.1</h2>

Step-by-step explanation:

<h3>{10}^{x}  = 1200</h3>

<u>To solve first take logarithm to both sides</u>

That's

<h3>log_{10}(10) ^{x}  =  log_{10}(1200)</h3><h3 /><h3>log_{10}(10)^{x}  = x log_{10}(10)</h3>

But

<h3>log_{10}(10)  = 1</h3>

So we have

x =  log_{10}(1200)

<u>Write 1200 as a number with the factor 100</u>

That's

1200 = 100 × 12

So we have

<h3>x =  log_{10}(100 \times 12)</h3>

<u>Using the rules of logarithms</u>

That's

<h3>log_{a}(x \times y)  =  log_{a}(x)  +  log_{a}(y)</h3>

Rewrite the expression

That's

<h3>x =  log_{10}(100)  +  log_{10}(12)</h3><h3 /><h3>x =  log_{10}(10)^{2}  +  log_{10}(12)</h3><h3>x = 2 log_{10}(10)  +  log_{10}(12)</h3><h3>log_{10}(10)  = 1</h3><h3 /><h3>x = 2 +  log_{10}(12)</h3>

x = 3.079

So we have the final answer as

<h3>x = 3.1 to one decimal place</h3>

Hope this helps you

I need help knowing what x equals to ?. please help!!
ivanzaharov [21]
<h2>Hello!</h2>

The answer is: x=6

<h2>Why?</h2>

Since we don't have the function equation, but we have the graphic, we can use it to know what value of x makes the function equal to 0.

Finding what values of x does g(x)=0 means that we should find where the function intercepts the x-axis.

From the graphic, we can see that the functions intercepts the x-axis at x=6

Have a nice day!

Sergio dives into the water and it takes him 6 seconds to reach the bottom of a pool that is 8 feet deep. What is the best numbe
marta [7]

Answer:  1.33

Step-by-step explanation:

Given : Time taken by Sergio to reach the bottom of a pool = 6 seconds

The depth of the bottom of the pool = 8 feet

We know that ,

\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}\\\\=\dfrac{8}{6}\text{feet per second}\\\\=1.33333333333\text{ feet per second}\\\\\approx1.33\text{ feet per second}

Hence, the  best number to describe Sergio's rate of speed in feet per second is 1.33.
