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]
To get ready for school supply shopping, a store orders 25,000 folders. The store gets another shipment of 15,250 folders the day before the sale.The store sells 32,400 folders the first day. How many folders does it have left after the first day?
Answer:
7,850
I’m pretty sure that’s right, I just added 25,000 and 15,250 together then subtracted the answer from 32,400 and got 7,850

If the area of a circle is 25pi (n), what is the radius of the circle
Answer:
5
Step-by-step explanation:
the are is pi times radius times radius
so do the square root of 25, which is 5.
this means that the radius is 5
Answer:
five (5).
Step-by-step explanation:
Area of circle =pi r^2
given that area is 25pi
now equate both .....we get
25pi=pi r^2
25=r^2
r=5

Find the height of a cone with a diameter of 12 m whose volume is 226 m^3.
Use 3.14 for it and round your answer to the nearest meter.
A. 5 m
B. 2 m
C. 19 m
D. 6 m
Answer:
D. 6m
Step-by-step explanation:
Ap3x
The height of a cone with a diameter of 12 m whose volume is 226 m^3 is 6 m
What is the cone of a height?The height of a cone is calculated using the formula:
h = 3V/πr 2
Where h = height of the cone
V = volume of the cone
r = Radius of the cone
But note that radius, r = diameter divided by 2
r = 12 ÷ 2 = 6m
Volume = 226 m^3
How to calculate the height of a coneSubstitute the values into the formula
h = 3 × 226 ÷ 3.14 × 6 × 6
h = 678 ÷ 113. 04
h = 6m
Therefore, the height of a cone with a diameter of 12 m whose volume is 226 m^3 is 6m

Francisca was supposed to multiply by 3/1, instead of subtracting by 1/3
Francisca was supposed to divide by 1/3, instead of subtracting by 1/3
Answer:
Francisca was supposed to divide by 1/3, instead of subtracting by 1/3.
Step-by-step explanation:
She was completing the equation correctly until she subtracted 1/3 instead of dividing both sides. It should have been 5 divided by 1/3 or 15/3 divided by 1/3.

A triangle has A, B, and C located at(-3, 0). (3, 0), and (0, 4), respectively, on the coordinate plane. The medians of (triangle)ABC intersect
at the point with which coordinates? Round each coordinate to the nearest tenth if necessary.
A. (1.5, 2)
B. (-1.5, 2)
C. (0, 1.3)
D. (0, 0)
Given:
Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).
To find:
The intersection point of all the medians of the triangle ABC.
Solution:
We know that, intersection point of all the medians of a triangle is called centroid.
The formula of centroid is
[tex]Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)[/tex]
Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).
[tex]Centroid=\left(\dfrac{-3+3+0}{3},\dfrac{0+0+4}{3}\right)[/tex]
[tex]Centroid=\left(\dfrac{0}{3},\dfrac{4}{3}\right)[/tex]
[tex]Centroid=\left(0,1.333...\right)[/tex]
Round each coordinate to the nearest tenth.
[tex]Centroid=\left(0,1.3\right)[/tex]
The coordinates of required point are (0,1.3). Therefore, the correct option is C.
find the additive inverse of-9x+3
Answer:
9x − 3
Step-by-step explanation:
−9x + 3 = −1(−9x + 3) Multiply the expression by −1.
−1(−9x) + −1(3) Distributive Property
9x − 3 Simplify.
The additive inverse of the given expression is 9x-3.
The given expression is -9x+3.
What is additive inverse?The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.
The additive inverse of the expression is -(expression).
Now, -(-9x+3)
= 9x-3
Therefore, the additive inverse of the given expression is 9x-3.

What is the best description of AB?
9514 1404 393
Answer:
F altitude
Step-by-step explanation:
AB is perpendicular to triangle base XZ, so is an altitude of the triangle.
__
Additional comment
B is not the midpoint of XZ, so AB is not the median and not a bisector of XZ. Likewise, AB is not the angle bisector of angle A. (The triangle would have to be isosceles for AB to be a perpendicular bisector, median, and angle bisector.)
Eliminating the choices that can't work leaves the one that does work. AB is the altitude.
Answer:
