Hey there! :)
Answer:
(3.5, -1).
Step-by-step explanation:
Use the midpoint formula to solve this problem:
[tex](x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
Plug in the coordinates given:
[tex](\frac{10-3}{2}, \frac{8-10}{2})[/tex]
Simplify:
[tex](\frac{7}{2}, \frac{-2}{2})[/tex]
Therefore, the coordinates of the mid-point are:
(3.5, -1).

Answer:
(a) t_n = 3n - 9
(b) t_16 = 39
Step-by-step explanation:
(a)
-3 - (-6) = -3 + 6 = 3
The common difference is 3.
t_1 = -6
t_2 = -6 + 3
t_3 = -6 + 3 + 3
t_4 = -6 + 3 + 3 + 3
t_n = -6 + 3(n - 1)
t_n = -6 + 3n - 3
t_n = -9 + 3n
t_n = 3n - 9
The formula is: t_n = 3n - 9
(b) t_16 = 3(16) - 9 = 48 - 9 = 39
Answer:
an = -6 + 3(n - 1)
a(16) = 39
Step-by-step explanation:
Explicit Formula: an = a1 + d(n - 1)
Our d (common difference) is +3
Our a1 (First term) is -6
To find a(16) (the 16th term), plug in 16 for n.

The half-life of a certain tranquilizer in the bloodstream is 47 hours. How long will it take for the drug to decay to 93% of the original dosage? Use the exponential decay model, Upper A equals Upper A 0 e Superscript kt, to solve.
Answer:
It will take 4.84 hours for the drug to decay to 93% of the original dosage.
Step-by-step explanation:
We are given that the half-life of a certain tranquilizer in the bloodstream is 47 hours.
The given exponential model is: [tex]A = A_0 e^{kt}[/tex]
Now, we know that A becomes half after 47 hours which means that;
[tex]A = 0.5 A_0[/tex]
Using this in the above equation we get;
[tex]A = A_0 e^{kt}[/tex]
[tex]0.5 A_0 = A_0 e^{(k\times 47)}[/tex] where t = 47 hours
[tex]\frac{0.5 A_0}{A_0} = e^{(47k)}[/tex]
[tex]0.5 = e^{47k}[/tex]
Taking log on both sides we get;
[tex]ln(0.5) = ln(e^{47k})[/tex]
[tex]ln(0.5) =47k[/tex]
[tex]k = \frac{ln(0.5)}{47}[/tex]
k = -0.015
Now, the time it will take for the drug to decay to 93% of the original dosage is given by;
[tex]0.93 = e^{kt}[/tex] where t is the required time
[tex]0.93 = e^{(-0.015 \times t)}[/tex]
Taking log on both sides we get;
[tex]ln(0.93) = ln(e^{-0.015t})[/tex]
[tex]ln(0.93) =-0.015t[/tex]
[tex]t = \frac{ln(0.93)}{-0.015}[/tex]
t = 4.84 hours
Hence, it will take 4.84 hours for the drug to decay to 93% of the original dosage.

Towns K and L are shown on a map-
a) Work out the actual distance
between towns K and L.
b) A third town, M, is 150 km due
South of town K.
Mark M on the map with X.
c) Measure the bearing of town L
from town K.
Answer:
a) Use a ruler for the measurement.
b) convert to centimetres then use a ruler to draw the unit on the diagram.
c) measure the angle between K and L from K
See explanations below
A complete question related to this found on brainly (ID:15577387) is stated below.
Towns K and L are shown on a map.
a) Work out the actual distance
between towns K and L.
b) A third town, M, is 150 km due
South of town K.
Mark M on the map with X.
c) Measure the bearing of town L
from town K.
Scale: 1cm represent 50km
Step-by-step explanation:
Scale: 1cm represent 50km
a) To find the actual distance between towns K and L use a ruler to measure the distance between K and L.
Your answer would be in centimetres (cm).
The answer obtained would be multiplied by 50km because from the scale given 1cm represent 50km.
Therefore you'll get the actual distance in km.
b) Here we are told M is 150 km due
South of town K.
Since the length of the initial diagram is in centimeters, we have to find how many centimeters equals 150km.
50km = 1cm
150km = (150km × 1cm)/50km = 150cm/50
150km = 3cm
Now we can represent the distance between K and M on the diagram.
Measure 3cm from K using a ruler in the direction of south (straight line downwards). The distance of M from K would be 3cm on the south of k.
c) Draw a cross on the position of K. Also draw a cross on the position of L. Connect the distance and measure the angle from K to L. The unit would be in degrees.
From the diagram, the angle is greater than 090° but less than 180°
Find attached the diagram.
Answer:
a) 100 km
b) check the photo of my work
c) 117 degrees
Step-by-step explanation:

11 Kenzie monitors her investment on a technology
stock. She uses the expression 2013e2+, where t
is the time in years, to estimate the future value
of the stock. What is the meaning of 2013 in this
context?
A. beginning year
B. invested amount
C. future value
D. annual growth rate
Answer:
B
Step-by-step explanation:
The term 2013 in this context refers to the amount invested.
Mathematically, in finance, we can express the amount to be recouped on an investment, having a particular rate of return over a couple of years using the general formula;
V = P(1+r)^t
Such as in the case of amount obtained in a compound interest formula
Where P is the present value or principal or amount invested
V is the future value
r is the rate of investment
with t being the time taken
6x + 7y + x-8y = 7x - y
Write down three other expressions that are equal to 7x - y
Answer:
It's pretty easy! You can manipulate the numbers to match the equation.
For example,
x + 8y + 6x - 9y = 7x - y
5x + 2x - 2y + y = 7x - y
10x + 7y - 3x - 8y = 7x - y
The other equivalent expressions that are equal to 7x - y could be; x + 8y + 6x - 9y = 7x - y, 5x + 2x - 2y + y = 7x - y and 10x + 7y - 3x - 8y = 7x - y
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; that can also be used to indicate the logical syntax's order of operations and other features.
We have been given the expression as;
6x + 7y + x-8y = 7x - y
When someone asks to solve an equation, then it usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).
The other equivalent expressions that are equal to 7x - y could be;
x + 8y + 6x - 9y = 7x - y
5x + 2x - 2y + y = 7x - y
10x + 7y - 3x - 8y = 7x - y

The box plots show the average speeds, in miles per hour, for the race cars in two different races. Average Speeds of Cars in Race A 2 box plots. The number line goes from 120 to 170. For Race A, the whiskers range from 120 to 170, and the box ranges from 143 to 165. A line divides the box at 153. For Race B, the whiskers range from 125 to 165, and the box ranges from 140 to 150. A line divides the box at 145. Average Speeds of Cars in Race B
Answer:
The median speed in race A is about 153 miles per hour, and the median speed in race B is about 145 miles per hour.
Step-by-step explanation:
For comparison, we need to analyze and compare both races data which are as follows
For Race A
Maximum range = 170 miles per hour
Minimum range = 120 miles per hour
First quartile ≈ 142 miles per hour
Median quartile ≈ 153 miles per hour
It comes from
[tex]= \frac{142\ miles + 165\ miles}{2}[/tex]
= 153 miles
The Third quartile = 165 miles per hour
For Race B
Maximum range = 165 miles per hour
Minimum range = 125 miles per hour
First quartile ≈ 139 miles per hour
Median quartile = 145 miles per hour
It comes from
[tex]= \frac{139\ miles + 150\ miles}{2}[/tex]
= 145 miles
The third quartile = 150 miles per hour
Hence, the last option is correct
A polynomial is factored using algebra tiles. An algebra tile configuration. 0 tiles are in the Factor 1 spot and 0 tiles are in the Factor 2 spot. 15 tiles are in the Product spot in 3 columns with 5 rows: 1 is labeled + x squared, 2 are labeled + x, the 4 tiles below + x squared are labeled negative x, and the 8 tiles below the + x tiles are labeled negative. Which polynomial was factored? x2 – 2x – 8 x2 + 2x – 8 x2 – 2x – 4 x2 + 2x – 4
Answer:
x² - 2x - 8
Step-by-step explanation:
Algebra tiles are tiles used to represent variables or numbers and are rectangular or square shaped.
1 is labeled + x squared, this gives x²
2 are labeled + x, this gives +x × 2 = +2x
4 tiles below + x squared are labeled negative x, this gives - x × 4 = - 4x
8 tiles below the + x tiles are labeled negative, this gives -1 × 8 = -8
Therefore to get the polynomial that was factored, we add all the terms. This gives :
+x² + (+ 2x) + (-4x) + (-8) = x² + 2x - 4x - 8 = x² - 2x - 8

Al saves pennies. He agreed to give six thirteenths of his pennies to Bev if she would give six thirteenths of what she got from Al to Carl and if Carl in turn would give six thirteenths of what he got from Bev to Dani. Bev, Carl, and Dani agreed and Dani received 2376 pennies. How many pennies did Al have initially?
Answer:
Step-by-step explanation:
Let x represent the number of pennies that Al had initially.
He agreed to give six thirteenths of his pennies to Bev. It means that the number of pennies that he gave to Bev is 6/13 × x = 6x/13
if she would give six thirteenths of what she got from Al to Carl, it means that the number of pennies that Carl received is 6/13 × 6x/13 = 36x/169
if Carl in turn would give six thirteenths of what he got from Bev to Dani and Dani received 2376 pennies, it means that
6/13 × 36x/169 = 2376
216x/2179 = 2376
216x = 2376 × 2179
216x = 5220072
x = 5220072/216
x = 24167
AI had 24167 pennies initially

Step-by-step explanation:
When two secant segments are drawn to a circle from an external point, the product of one secant segment and its external segment equals the product of the other secant segment and its external segment.
6 times 18 = 5(5+x)
The total secant segment is 6+12=18
so one side = 6 times 8.
The line from the circle (but not inside) is 5.
You don't know the entire segment, but you do know that 5 is part of it. Hence 5 times (5+x).

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
A restaurant catered an event for 25 people.
A child’s dinner cost $5 and an adult’s dinner cost $22.
The party cost $431.
let the number of children attendee be x and adult attendee be y.
So, x+ y = 25..............(1)
and, 5x + 22y = 431.......(2)
Solving the Equation (1) and (2) we get
5(25 - y) + 22y= 431
125 - 5y + 22y= 431
17y = 431-125
17y = 306
y = 18
and, x= 25-18 = 7
Hence, there was 7 children attendee and 17 adult attendee.

. Mr. Wayne has a 3-year contract for his cell phone service. He pays $124.65 each month to cover everyone in his family. How much will the cell phone service cost over the 3-year period? Explain your answer
Answer:
$4,523.40
Step-by-step explanation:
The cell phone cost is $124.65 per month. With 12 months in a year, we multiply $124.65 x 12 to get the answer $1,507.80. Since one year equals $1,507.80, we multiply this answer by 3 for 3 years to get $4,523.40. Thus three years of service with $124.65 a month would equal $4,523.40.
Use the given information to draw a box-and-whisker plot of the data set
Minimum – 28
Maximum – 54
Lower Quartile – 32
Upper Quartile – 40
Answer:
The box-and-whisker plot of this distribution is presented in the attached image to this solution.
Step-by-step explanation:
A box plot gives a visual representation of the distribution of the data, showing where most values lie and those values that greatly differ from the rest, called outliers.
A box and whiskers plot shows 5 major information about the distribution of data. It shows:
- The maximum variable.
- The minimum variable.
- The Median.
- The first quartile.
- The third quartile.
Further info such as the range and Inter quartile range can then be obtained from this 5-number summary.
The elements of the box plot are described thus;
The bottom side of the box represents the first quartile, and the top side, the third quartile. Therefore, the width of the central box represents the inter-quartile range.
The horizontal line inside the box is the median.
The lines extending from the box reach out to the minimum and the maximum values in the data set, as long as these values are not outliers. The ends of the whiskers are marked by two shorter horizontal lines.
Variables in the dataset, higher than Q3+(1.5×IQR) or lower than Q1-(1.5×IQR) are considered outliers and are usually shown using dots above the top whisker or below the bottom whisker.
The required boxplot for this question is given in the attached image to this solution.
The median for the boxplot isn't provided, but it was assumed to be midway between the first and third quartile.
