inna [77]

Answer:

Step 1 is wrong

Step-by-step explanation:

$\frac{1}{4} r+ 2 = 10$

$\frac{r}{4} + 2 = 10$

$\frac{r}{4} = 10 - 2$

$\frac{r}{4} = 8$

$r = 8 \times 2$

$r = 32$

A large cube is made up of many small cubes. The volume of the large cube is 7.506×10^5mm^3. The volume of each small cube is 2.

irakobra [83]

Answer:

27 small cubes

Step-by-step explanation:

Given that,

The volume of the large cube is $7.506\times 10^5\ mm^2$

The volume of small cube is $2.78\times 10^4\ mm^2$

We need to find how many small cubes make up the large cube. Let there are n small cubes. So, it can be calculated as follows :

$n=\dfrac{7.506\times 10^5}{2.78\times 10^4}\\\\n=27$

So, there are 27 small cubes that make up of the large cube.

Which is the best approximation to a solution of the equation e^x = 2x + 3?

TiliK225 [7]

The correct question is
Which is the best approximation to a solution of the equation
e^(2x) = 2e^{x) + 3?

we have that

e^(2x) = 2e^{x) + 3-----------> e^(2x)- 2e^{x) - 3=0
the term
e^(2x)- 2e^{x)----------> (e^x)²-2e^(x)*(1)+1²-1²------> (e^x-1)²-1

then
e^(2x)- 2e^{x) - 3=0--------> (e^x-1)²-1-3=0------> (e^x-1)²=4
(e^x-1)=2--------> e^x=3
x*ln(e)=ln(3)---------> x=ln(3)
ln(3)=1.10
hence
x=1.10

the answer is x=1.10
