goldfiish [28.3K]

Answer: 11, 30

Step-by-step explanation:

Given

There were a total of 41 national battlefields and national memorials

Suppose there are $x$ national battlefields

So, national memorials are $3x-3$

The sum of the two must be 41

$\Rightarrow x+3x-3=41\\\Rightarrow 4x=44\\\Rightarrow x=11$

So, there are 11 national battlefields and $3\times 11-3=30$ national memorials.

5 rational and irrational numbers in decimal form

alexira [117]

Answer:

A rational number is a number that can be expressed as a fraction (ratio). This includes whole numbers, square roots that can be solved evenly, negatives, decimals, and repeating decimals that can be solved with a fraction.

$\frac{1}{2}$ ↔ .5
5 ↔ 5.0
$\sqrt{4}$ ↔ 2.0
-13 ↔ -13.0
0.38462... ( $\frac{5}{13}$ )

An irrational number is a number that is NOT rational. It's the complete opposite!

π ↔ 3.14159
.13133133...
$\frac{\sqrt{3} }{2}$ ↔ 0.86603...
- $\sqrt{5}$ ↔ -2.23607...
$\sqrt{5}$ ↔ 2.23607...

Hope this helps!!!

6. Let f and g be differentiable functions

Julli [10]

Answer:

(b) 1

Step-by-step explanation:

To differentiate $h(x)=f(x)g(x)$ we will need the product rule:

$h'(x)=f'(x)g(x)+f(x)g'(x)$ .

We have $h'(x)=f(x)g'(x)$ , so the following equation is true by the transitive property:

$f'(x)g(x)+f(x)g'(x)=f(x)g'(x)$

By subtraction property we have:

$f'(x)g(x)=0$

Since $g(x) \neq 0$ , then we can divide both sides by $g(x)$ :

$f'(x)=\frac{0}{g(x)}$

$f'(x)=0$

This implies $f(x)$ is constant.

So we have that $f(x)=c$ where $c$ is a real number.

Since $f(0)=1$ and $f(0)=c$ , then by transitive property $1=c$ .

So $f(x)=1$ .

Checking:

$h(x)=1 \cdot g(x)$

$h'(x)=g'(x)=1 \cdot g'(x)$

So the following conditions were met.
