Answer:
<h2>x = 3.1</h2>
Step-by-step explanation:
<h3>
</h3>
<u>To solve first take logarithm to both sides</u>
That's
<h3>
</h3><h3 /><h3>
</h3>
But
<h3>
</h3>
So we have
<u>Write 1200 as a number with the factor 100</u>
That's
1200 = 100 × 12
So we have
<h3>
</h3>
<u>Using the rules of logarithms</u>
That's
<h3>
</h3>
Rewrite the expression
That's
<h3>
</h3><h3 /><h3>
</h3><h3>
</h3><h3>
</h3><h3 /><h3>
</h3>
x = 3.079
So we have the final answer as
<h3>x = 3.1 to one decimal place</h3>

Answer:
4j+24k
Step-by-step explanation:
Expand by distributing terms.
4j+4\times 6k
4j+4×6k
2 Simplify 4\times 6k4×6k to 24k24k.
4j+24k
4j+24k
The answer is $16216987.55 (IMPORTANT: This is the answer assuming that the interest rate is annually. The quesiton says 'continuously' so I was a bit confused)
To solve this problem, you can use the compound interest formula.
Here it is once you plug in the numbers: A = 5,000,000 ( 1 + .04) ^30
Just solve the equation to find the solution.
This is a problem of
fact families, but <em>what is fact families?</em> Well it is a family of four things. Two of them are additions and two of them are subtractions. So this question asks about fact families by w<span>riting the <em>subtraction fact two ways</em>. So we have:

First way. So let's take the number 10 and explain this problem using triangles. Let's say that we have 10 triangles in the beginning:
</span>Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ
So I want to take away 3 triangles, then by taking away 3<em> what is left? </em>Well the answer is 7:
Δ Δ Δ Δ Δ
Δ Δ
That is, if we subtract 3 from 10 then the result is:
Second way. In this subtraction we take the same 10 triangles:
Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ
Now I want to take away 7 triangles, then by taking away 7 what is left is 3:
Δ Δ Δ
That is, if we subtract 7 from 10 then the result is:
