Find an equation for the perpendicular bisector of the line segment whose endpoints
are (7,4) and (-5,8).
9514 1404 393
Answer:
y = 3x +3
Step-by-step explanation:
The midpoint of the given segment is a point on the line. That point is ...
M = ((7, 4) +(-5, 8))/2 = (7-5, 4+8)/2 = (1, 6)
The difference between the end points can be helpful in writing the equation.
(-5, 8) -(7, 4) = (-12, 4) = (Δx, Δy)
Then the general form of the equation of the perpendicular bisector can be written as ...
Δx(x -Mx) +Δy(y -My) = 0 . . . . . where midpoint M = (Mx, My)
-12(x -1) +4(y -6) = 0
Dividing by -4 and eliminating parentheses, we have ...
3(x -1) -(y -6) = 0
3x -y +3 = 0 . . . . general form equation for the line
y = 3x +3 . . . . . . slope-intercept form equation
Which inequality is graphed? PLEASEEEE ANYONEEE!! I NEED HELP!
Answer:
the answer is C
Step-by-step explanation:
Because if you look at the slope and find the rise over run you wil get 1/2 slope then next you have the dotted which means you have a < or > symbol. After that you see the gray shaded area is where the y is in terms with the equation. since the shaded area is above hte line that means the y must be greater than (>) the line and not on it.
which gives us y>1/2x+1

Determine if the given sequence is geometric. If the sequence is geometric, find the common ratio. −4, −1, 1, −4,...
A. The sequence is geometric. The common ratio is________. (Type an integer or a simplified fraction.)
B. The sequence is not geometric.
C. It cannot be determined whether the sequence is geometric or not
Answer:
answer is (c) it cannot be determined whether the circumference is the geometrical or not
Answer:
B
Step-by-step explanation:
To determine if a sequence is geometric, the terms need to have a common ratio. This means that to get from one term to the next, you need to multiply by the same number. Here's an example geometric sequence:
1) 2, 4, 8, 16, 32...
2) 4, 6, 9...
As you can see, to get from one term to the next in both of these sequences, you need to multiply by a certain number [the common ratio]. In sequence one, this number is 2. You need to multiply a term by 2 to get to the next term. In the second sequence, this number is 3/2. To find this certain number/common ratio, you can set the terms into ratios:
9/6=3/2
6/4=3/2
This ratio between the terms we get is the common ratio. Multiplying by this number will get you to the next term.
In this case [-4, -1, 1, -4...]:
[tex]\frac{-4}{1}=-4[/tex]
[tex]\frac{1}{-1} =-1[/tex]
[tex]\frac{-1}{-4}=\frac{1}{4}[/tex]
The ratios produced by the terms clearly aren't the same here, so the sequence is not geometric.

Answer:
1.)10 2.)0 3.)10
Step-by-step explanation:
1.) 4 (2) = 8 + 2 = 10
2.) 2(2) - 4/5 = 0
3.)2y + 11/-11 = +3y/-3y +1
2y - 3y = 1 - 11

In the cafeteria, 100 juice boxes were put out for lunch. At the end of lunch, 23 juice boxes remained.
What is the Ratio of juice boxes taken, to total juice boxes?
What is the Ratio of juice boxes remaining, to juice boxes taken?
Answer:
a) [tex]\huge\boxed{\sf 77:100}[/tex]
b) [tex]\huge\boxed{\sf 23 : 77}[/tex]
Step-by-step explanation:
Total Juices box = 100
Juices boxed taken = 100 - 23 = 77
Juices boxes remaining = 23
[tex]\rule[225]{225}{2}[/tex]
Ratio of juice boxes taken to total juice boxes:
= 77 : 100
[tex]\rule[225]{225}{2}[/tex]
Ratio of juice boxes remaining, to juice boxes taken:
= 23 : 77
[tex]\rule[225]{225}{2}[/tex]

Situation:
A geologist in South America discovers a
bird skeleton that contains 47% of its
original amount of C-14.
N = Noekt
No = inital amount of C-14 (at time
t = 0)
N = amount of C-14 at time t
k= 0.0001
t = time, in years
Find the age of the bird skeleton to the nearest year.
Answer:
7550 years
Step-by-step explanation:
From;
N = Noe^-kt
No = inital amount of C-14 (at time t = 0)
N = amount of C-14 at time t
k= 0.0001
t = time, in years
Now we have been told in the question that N =0.47 No
So we have;
0.47 No = Noe^-0.0001 t
0.47 No/No = e^-0.0001 t
0.47 = e^-0.0001 t
ln 0.47 = ln e^-0.0001 t
-0.7550 = -0.0001 t
t = 0.7550/0.0001
t = 7550 years

What is true regarding two adjacent arcs created by two
intersecting diameters?
Given:
Two diameters intersect each other.
To find:
The correct statement regarding two adjacent arcs created by two intersecting diameters.
Solution:
We know that, two diameter intersect each other at origin and measure of arc is equal to the corresponding angle generated by the intersection of diameters.
If two lines intersect each other then we get 4 angles and sum of any two adjacent angles is 180°.
It means the sum of any two adjacent central angles generated by the intersection of diameters is 180°.
So, the sum of two adjacent arcs created by two intersecting diameters is 180°.
Therefore, the correct option is C.
The average distances between some objects in our solar system are described below.
• The average distance from Earth to the Moon is 3.844 × 105 kilometers (km).
• The average distance from Jupiter to the Sun is approximately 2 × 103 times the average distance from Earth to the Moon.
Based on this information, what is the average distance from Jupiter to the Sun
7.688 × 10, 2, km
7.688 × 10, 5, km
7.688 × 10, 8, km
7.688 × 10, 15, km, ,
Answer:
Jupiter to Sun = 7.688 * 10⁸km
Step-by-step explanation:
Given
Earth to Moon = 3.844 * 10⁵km
Jupiter to Sun = 2 * 10³ times Earth to Moon
Required
Determine the average distance from Earth to Moon
Jupiter to Sun = 2 * 10³ times Earth to Moon
Substitute 3.844 * 10⁵km for Earth to Moon
Jupiter to Sun = 2 * 10³ * 3.844 * 10⁵km
Collect Like Terms
Jupiter to Sun = 2 * 3.844 * 10³ * 10⁵km
Jupiter to Sun = 7.688 * 10³ * 10⁵km
Jupiter to Sun = 7.688 * 10⁸km

Quadrilateral A B C D is shown. Sides A D and B C are parallel. Sides A B and C D are congruent. Angle A is 115 degrees. What is the measure of ADC in quadrilateral ABCD? 45° 65° 115° 135°
Step-by-step explanation:
Since sides AD and BC are parallel,
Angle BAD + Angle ADC = 180° (co-interior angles)
Therefore Angle ADC = 180° - 115° = 65°.
Answer:
65° if parallelogram115° if trapezoidStep-by-step explanation:
Since no diagram attached there are two possible options.
Option 1
The quadrilateral is parallelogram.
In this case ∠A and ∠D sum up to 180°, therefore:
∠ADC = 180° - 115° = 65°Option 2
The quadrilateral is isosceles trapezoid.
In this case ∠A is congruent with ∠D, therefore:
∠ADC = ∠A = 115°8k-5k

Answer:
D. 3
Step-by-step explanation:
The sides with lengths 25 and 5 are corresponding, so their ratio is 25/5 = 5/1
The sides with lengths 18 - x and x are also in a 5 to 1 ratio.
5/1 = (18 - x)/x
5x = 18 - x
6x = 18
x = 3

Write the expression as the square of a binomial.
The expression is
I need this to be answered asap and a step by step explanation please, do not comment if you do not know the answer !
Answer:
c = 121
Step-by-step explanation:
Given
t² - 22t
To complete the square
add ( half the coefficient of the t- term )² to t² - 22t
= t² + 2(- 11)t + (- 11)²
= t² - 22t + 121
with c = 121
Thus
t² - 22t + 121 = (t - 11)²
