The shortest path from point A to point B goes through a pond. To avoid

1 answer:

61.47 meters
You can use Pythagorean’s Theorem here which is a^2+b^2=c^2
Walking across would be the hypotenuse. So 23^2+57^2=c^2
529+3249=3778
And the sqrt of 3778 will be the answer which is about 61.47 meters

Find the slope of the lines. Are the 2 lines parallel or perpendicular? Explain how you can use the slope of two lines to tell i

rewona [7]

Answer:

slope = $\frac{3}{7}$ and - $\frac{7}{3}$ , perpendicular

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = $\frac{3}{7}$ x + 11 is in this form with m = $\frac{3}{7}$

Rearrange 7x + 3y = 13 into this form

subtract 7x from both sides

3y = - 7x + 13 ( divide all terms by 3 )

y = - $\frac{7}{3}$ x + $\frac{13}{3}$ ← in slope- intercept form

with m = - $\frac{7}{3}$

• Parallel lines have equal slopes

• The product of perpendicular slopes = - 1

The lines are not parallel since slopes are not equal

$\frac{3}{7}$ × - $\frac{7}{3}$ = - 1

Hence lines are perpendicular

Find the midpoint of the line segment joining the points (6,1) and (-2, -1).

tiny-mole [99]

Step-by-step explanation:

By the formula of slope, we have

$( \frac{y _{2} - y_{1} }{x _2 - x _{1} }) \\ ( \frac{ - 1 - 1}{ - 2 - 6} ) \\ ( \frac{ - 2}{ - 8} ) \\ ( \frac{1}{4} )$

Since the exponent of the scientific notation is positive, move the decimal point 6 places to the right.

1620000

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps :)
