The midpoint of two points is given as
(x1 + x2)/2, (y1 + y2)/2
Given that the coordinates of the midpoint are (5, -1), let the coordinates of point B be x2 and y2
(2 + x2)/2 = 5
2 + x2 = 10
x2 = 10 - 2
x2 = 8
(-6 + y2)/2 = -1
-6 + y2 = -2
y2 = -2 + 6
y2 = 4
The coordinates of B are (8,4)
What is the measure of angle D?
(Geometry) with details and steps!!!
Answer:
See below
Step-by-step explanation:
The angle at E in the UPPER triangle
is 180 - -45 -14 = 121° ( because the angles of any triangle sum to 180 °)
The angle below this is the same value 121°
then 27 + 121 + D = 180 shows D = 32°
Answer:
32°
Step-by-step explanation:
If you look at the figure there are two distinct triangles formed by the intersection of the two lines
These are ΔAEB and ΔCED
Consider ΔAEB
Two of its angle measure are given:
m∠EAB = 14° and m∠EBA = 45°
The measure of the third angle ∠AEB can be computed from the fact that the sum of the three angles of a triangle add up to 180°
So we get the equation:
14 + 45 + m∠AEB = 180
59 + m∠AEB = 180
m∠AEB = 180 -59 = 121°
We also have
m∠AEB = m∠CED
since they are vertically opposite angles formed at intersection E by the two straight lines AD and BC
So m∠CED = 121°
Now considering the triangle ΔCED we have two angles known to us
m∠ECD = 27° and m∠CED = 59°
The sum of the measures of the three angles ∠ECD, ∠CED and ∠CDE must add up to 180°
==> 27 + 121 + ∠CDE = 180
148 + ∠CDE = 180
∠CDE = 180 - 148 = 32°
So ∠D measures 32°
What are the coordinates of the point on the directed line segment from (-9, 2) to
(5,-10) that partitions the segment into a ratio of 1 to 3?
[1.5, 4] are the coordinates that divide the section into a 3 to 1 ratio.
Using a 3:1 partitioning ratio
#Multiply the ratio by the length of the x-coordinate:
5 + 9 = 14;
1/4 of 14 is 3.5;
we take this value out of the x-max to get the point, which is 5 - 3.5 = 1.5.
#Multiply the ratio by the length of the y-coordinate:
We subtract -2 from the y-max to obtain the point,
which is equal to 2 + 2 = 4.
x length -10 + 2
=> 1/4 x -8 = - 2
Consequently, [1.5, 4] are the coordinates that divide the section into a 3 to 1 ratio.

A pipe is at least 21 feet long and you want to cut it into three pieces
The length of the each piece of pipe is 7 feet
What is Length?
Distance is measured in length. Length has the dimension of distance in the International System of Quantities. The majority of measurement systems choose a base unit for length from which all other units are derived. The meter serves as the foundational unit of length in the International System of Units.
Given,
Total length of the pipe = 21feet
The pipe after 3 pieces = ?
We have to find the length of pipe after it is cut down into three piece
To find that we have to divide the length of the pipe with 3
The length of 3 pieces = 21/3
= 7 feet
Hence, The length of each piece will be 7 feet

Tracy opened a savings account and deposited $600.00. The account earns 4% interest,compounded annually. If she wants to use the money to buy a new bicycle in 3 years, howmuch will she be able to spend on the bike?Round your answer to the nearest cent.
The compound interest formula is:
[tex]C(n)=P\lbrack(1+i)^n-1\rbrack[/tex]Where:
C(n) is the interest generated after n periods
P is the principal value, the values deposited initially.
i is the annual interest rate in percentage terms.
n is the number of compounding periods.
In this case:
P = $600.00
i = 0.04 (converted from percentage to decimal by dividing by 100
n = 3 years
Then:
[tex]C(3)=600.00\lbrack(1+0.04)^3-1\rbrack[/tex]Then solve:
[tex]C(3)=600\lbrack1.04^3-1\rbrack=600\lbrack1.124864-1\rbrack=600\cdot0.124864=74.9184[/tex]This is the amount of interest generated over 3 years. The total amount then will be the initial amount plus the interest generated:
[tex]600+74.9184=674.9184[/tex]Rounded up to the nearest cent, the amount she will be able to spend after 3 years is $674.91

(5 points)1. $32. $93. $184. $27
Solution
Step by step explanation:
Using the data, we can calculate the price per bottle for Brand A, which is:
24 / 2
= $12 per bottle
We also know that the slope of a line shows the rate of change, so the price per bottle for Brand B is $15.
The difference per bottle is 15 - 12 = Brand B is cost $3 more per bottle
The difference for 9 bottles will be: 9 * 3 = $27.
Therefore the answer will be $27

The value of (p² + 1/p²) and (p + 1/p)²is 18 and 20 respectively.
The above question is from algebra section and is from the topic surds and indices.
One of the standard formula is
(a - b)² = a² - 2ab +b²
(i) Here the expression is
p - 1/p = 4 and we need to find the value of p² + 1/p²
(p - 1/p)² = p² + 1/p² -2p(1/p)
4² = p² + 1/p² - 2
16 + 2 = p² + 1/p²
p² + 1/p² = 18
(ii) we need to find the value of (p + 1/p)²
(a + b)² - (a - b)² = 4ab
(p + 1/p)² - (p - 1/p)² = 4p(1/p)
(p + 1/p)² - 4² = 4
(p + 1/p)² = 4 + 16
(p + 1/p)² = 20
Therefore, the value of (p² + 1/p²) and (p + 1/p)² is 18 and 20 respectively.

For y = 10*0.5^x , doesthis model exponential growth or decay? Explain how you know.
Answer:
Exponential decay
Explanation:
The exponential functions have the following form:
[tex]y=a\cdot b^x[/tex]If b is a number greater than 1, the equation models exponential growth, and if b is lower than 1, the equation models an exponential decay.
Since the equation is:
[tex]y=10\cdot0.5^x[/tex]We can say that the value of b is 0.5. 0.5 is lower than 1, so this equation models exponential decay.
