whats the equation for the perpendicular bisector of the line segment whose endpoints are (-5,3) and (3,7)?
Answer:
The equation of perpendicular bisector of the line segment passing through (-5,3) and (3,7) is: [tex]y = -2x+3[/tex]
Step-by-step explanation:
Given points are:
(-5,3) and (3,7)
The perpendicular bisector of line segment formed by given points will pass through the mid-point of the line segment.
First of all we have to find the slope and mid-point of given line
Here
(x1,y1) = (-5,3)
(x2,y2) = (3,7)
The slope will be:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{7-3}{3+5}\\m = \frac{4}{8}\\m = \frac{1}{2}[/tex]
The mid-point will be:
[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\ = (\frac{-5+3}{2},\frac{3+7}{2})\\= (\frac{-2}{2},\frac{10}{2})\\=(-1,5)[/tex]
Let m1 be the slope of the perpendicular bisector
Then using, "Product of slopes of perpendicular lines is -1"
[tex]m.m_1 = -1\\\frac{1}{2}.m_1 = -1\\m_1 = -1*2\\m_1 = -2[/tex]
We have to find the equation of a line with slope -2 and passing through (-1,5)
The slope-intercept form is given by:
[tex]y = mx+b\\y = -2x+b[/tex]
Putting the point (-1,5) in the equation
[tex]5 = -2(-1)+b\\5 = 2+b\\b = 5-2\\b = 3[/tex]
The final equation is:
[tex]y = -2x+3[/tex]
Hence,
The equation of perpendicular bisector of the line segment passing through (-5,3) and (3,7) is: [tex]y = -2x+3[/tex]

Lancé le 26 novembre 2011, le Rover Curiosity de la Nasa est chargé d'analyser la planète Mars. il a atterri sur la planète rouge le 6 août 2012, parcourant ainsi une distance d'environ 560 millions de kilomètres en 255 jours. quelle est la durée du vol?
Answer: La durée de la vol entire est 560 millions de miles. La durée par hour est 2.19 millions de miles par hour.
Step-by-step explanation: Je ne sais pas sûr que Je comprends la question exactement. Si on doit trouver la durée par hour, il faut divider 560000000 par 255.

Answer: t= 11.5
Step-by-step explanation: 5 + (-11.5+3) = 3.5
Answer:
T = -3.7
Step-by-step explanation:
We begin with the given equation.
5(t+3)=-3.5
Distribute 5 throughout parentheses.
5t + 15 = -3.5
Move 15 to the other side and switch signs.
5t = -3.5 - 15
Combine like terms.
5t = -18.5
Divide by 5t.
t = -3.7

The top running speed of a giraffe is 250% of the top speed of a squirrel. If a squirrel’s top running speed is 12 miles per hour, find the speed of a giraffe.
Answer:
30
Step-by-step explanation: First take the fastest speed of the squirrel, and then you multiply it by the percentage (250%). You can this by moving on decimal point to the left from the zero (250% = 2.50). Then multply the speed of the squirrel by said percentage of the girrafe,
12 x 2.5 = 30

15%Step-by-step explanation:
Actual number = 172Estimated number = 198Error:
198 - 172 = 26Percent error:
26/172*100% = 15% rounded to the whole numberStep-by-step explanation:
[tex]\% \: error = \frac{198 - 172}{172} \times 100 \\ = \frac{26}{172} \times 100 \\ = 15\%[/tex]
15%(approx) is the right answer.A milk truck delivers 457 dozen gallons of milk to stores in 1 day. Write and solve an equation to find g, the number of gallons of milk the milk truck delivers in 1 day I don't get it help!
Answer:
5484 gallons
Step-by-step explanation:
Given that:
Delivery in 1 day = 457 dozen gallons
g = number of gallons delivered on that day
Recall :
1 dozen = 12
Therefore, the number of gallons delivered in 1 day :
457 gallons * 12 = 5484 gallons

Solve. Express your answer as a mixed number. 5 feet= ______ yards Solve. I need an explanation on how to put it as a mixed number and how to solve it.
Answer: 5 feet= __5/3 0r 1 2/3____ yards
Step-by-step explanation:
Step 11 yard = 3 feet
3 feet = 1 yard
5 feet = 5feet x 1 yard/ 3feet
= 5/3yards
Step 2 To convert 5/3 yards to a mixed fraction,
1. We first Divide the numerator, 5 by the denominator, 3 giving us a whole number and a remainder
5/3 = 1 remainder 2
2.then we write the whole number and put the remainder 2 above the denominator 3 giving us
5/3 = 1 2/3
such that when you multiply the mixed fraction 3 x 1 and add 2 it gives back the improper fraction of 5/3
