What's 34.6 times 10 to the second power in scientific notation

2 answers:

7 0

First off, 10 to the second power is 100; if you didn't know. There are 2 zeros in 100 which means you have to move the decimal point 2 digits to the right. 34.6 would turn into 3460

Since it's 10 to the 2nd power, you just move the decimal places 2 places to the right.

So the answer is 3460

Answer:

$y = -3x + 14$

Step-by-step explanation:

Required

The equation of line

perpendicular to : $x -3y =9$

Passes through $(3,5)$

We have:

$x -3y =9$

Make y the subject

$3y =x - 9$

Solve for y

$y = \frac{x}{3} - 3$

Compare the above equation to $y = mx + c$

$m =\frac{1}{3}$ ---- This represents the slope

Since the line is perpendicular to $x -3y =9$ , then its slope is:

$m_2 = -\frac{1}{m}$

$m_2 = -\frac{1}{1/3}$

$m_2 =-3$

The equation of the perpendicular line is:

$y =m_2(x - x_1) + y_1$

Where:

$m_2 =-3$

$(x_1,y_1) =$ $(3,5)$

So:

$y = -3(x - 3) + 5$

$y = -3x + 9 + 5$

$y = -3x + 14$

АBсDIf AC = 22x - 19, find x. Round your answer to the nearest tenth ifnecessary.AB = 4x + 31BC = 29

mihalych1998 [28]

Answer:

The value of x is equal to 4.4.

$x=4.4$

Explanation:

Given;

$\begin{gathered} AC=22x-19 \\ AB=4x+31 \\ BC=29 \end{gathered}$

The length AC is the sum of length AB and BC;

$AC=AB+BC$

substiuting the given values;

$\begin{gathered} AC=AB+BC \\ 22x-19=4x+31+29 \\ 22x-19=4x+60 \end{gathered}$

let's add 19 to both sides, and then subtract 4x from both sides;

$\begin{gathered} 22x-19=4x+60 \\ 22x-19+19=4x+60+19 \\ 22x=4x+79 \\ 22x-4x=4x-4x+79 \\ 18x=79 \end{gathered}$

divide both sides by 18;

$\begin{gathered} \frac{18x}{18}=\frac{79}{18} \\ x=4.388888 \\ x=4.4 \end{gathered}$

The value of x is equal to 4.4.

$x=4.4$
