Which exponent is missing from this equation<br> 5.6=56,000

Neko [114]

Answer:

The missing exponent is 4

Step-by-step explanation:

Let

$5.6 \times {10}^{n} = 56000$

Then we rewrite the LHS in scientific notation to get;

$5.6 \times {10}^{n} = 5.6 \times {10}^{4}$

This implies that,

${10}^{n} = {10}^{4}$

By comparison, we find n=4.

Therefore the missing exponent is 4

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, 1) and (0, 3). Everything to th

Allushta [10]

Answer:

$y>\frac{2}{3}x+3$

Step-by-step explanation:

step 1

Determine the slope of the dashed line

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-3,1) and (0,3)

substitute

$m=\frac{3-1}{0+3}$

$m=\frac{2}{3}$

step 2

Find the equation of the dashed line in slope intercept form

$y=mx+b$

we have

$m=\frac{2}{3}$

$b=3$ ---> given problem

substitute

$y=\frac{2}{3}x+3$

step 3

Find the equation of the inequality

we know that

Is a dashed line and everything to the left of the line is shaded

$y>\frac{2}{3}x+3$

see the attached figure to better understand the problem

Figure ABCD is a rhombus. Find the value of x. <br><br> 58° <br><br> x = [ ? ]°

melisa1 [442]

The diagonals of the rhombus intersect at right angle. Then the value of x will be 32°.

<h3>What is a rectangle?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. In a rhombus, opposite sides are parallel and equal.

Figure ABCD is a rhombus.

Its diagonals intersect at right angle.

Let the another angle be x. Then we have

x + 58° + 90° = 180°

x + 148° = 180°

x = 32°
