Answers
If M is the midpoint of AB , B(-7,16) and M(-2,8) then coordinates of the missing endpoint A are (3,0).
As given in the question,
M is the midpoint of AB
Let coordinates of A(x₁ ,y₁) , B(x₂ ,y₂) and M(x ,y)
So,
x = (x₁ + x₂)/2
⇒-2 = (x₁ + (-7))/2
⇒ x₁ = 7-4
⇒x₁ =3
y = (y₁+ y₂)/2
⇒8 = (y₁ +16)/2
⇒ y₁ = 16-16
⇒ y₁ =0
Therefore, if M is the midpoint of AB , B(-7,16) and M(-2,8) then coordinates of the missing endpoint A are (3,0).

Explain how to find the area of a trapezoid with height 4.2 m and bases of 6.3 m and 8.1 m. Give the area in your answer.
Answers
Answer:
A=30.24
Step-by-step explanation:
A=1/2h(b1 +b2)
A =1/2×4.2×(6.3+8.1)
A =1/2x4.2(14.4)
A=30.24
30.24m
Explanation:
To find the answer, it is important to know the the formula for finding the area of a trapezoid.
Formula -
A = a + b/ 2 • h
• ‘A’ represents the total area of the trapezoid
• ‘a’ represents the first base
• ‘b’ represents the second base
• ‘h’ represents the height
Now that we know the formula, substitute the variables in the formula with the values given.
A = a + b/ 2 • h
A = 6.3 + 8.1/ 2 • 4.2
Next, solve for ‘A.’
Step 1 - Add both bases
A = 6.3 + 8.1/ 2 • 4.2
A = 14.4/ 2 • 4.2
Step 2 - Divide 14.4 by 2
A = 14.4/ 2 • 4.2
A = 7.2 • 4.2
Step 3 - Multiply
A = 7.2 • 4.2
A = 30.24
Therefore, the total area of a trapezoid with the height of 4.2m and bases of 6.3m and 8.1m is 30.24m.
Find the Nth Term: 2, -6, -14, -22.

Step-by-step explanation:
there is a common difference between consecutive terms , that is
- 6 - 2 = - 14 - (- 6) = - 22 - (- 14) = - 8
this indicates the sequence is arithmetic with nth term
\(a_{n}\) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 2 and d = - 8 , then
\(a_{n}\) = 2 - 8(n - 1) = 2 - 8n + 8 = - 8n + 10
Jim is buying some clothes at Kohls. He buys a jacket that costs $75 and 5 pairs of shorts that each cost the same amount. He spends a total of $175 on the shorts and jacket. Write and solve an equation to find the cost of each pair of shorts.
Answers
The equation to find the cost of each pair of shorts is 175 = 75 + 5x where each short cost $20
How to write and solve an equation?Cost of jackets= $75
Number of shorts= 5
Cost of each short = x
Total amount Jim spent= $175
Total amount Jim spent = Cost of jackets + (Number of shorts × Cost of each short)
175 = 75 + 5x
subtract 75 from both sides
175 - 75 = 5x
100 = 5x
divide both sides by 5
x = 100/5
x = $20
Ultimately, each pair of shorts cost $20

A concave shaving mirror has a radius of curvature of +31.5 cm. It is positioned so that the (upright) image of a man's face is 3.40 times the size of the face. How far is the mirror from the face? Number i Units
Answers
The data includes a concave mirror with a radius of curvature of +31.5 cm and magnification of m = 3.40. The formula for magnification is m = v/u, and the focal length is f = r/2. Substituting the values, we get u = v/m, and using the mirror formula, the distance of the object from the mirror is 10.15 cm.
Given data: Radius of curvature of a concave mirror, r = +31.5 cm Magnification produced by the mirror, m = 3.40
We know that the formula for magnification is given by:
m = v/u where, v = the distance of the image from the mirror u = the distance of the object from the mirror We also know that the formula for the focal length of the mirror is given by :
f = r/2where,f = focal length of the mirror
Using the mirror formula:1/f = 1/v - 1/u
We know that a concave mirror has a positive focal length, so we can replace f with r/2.
We can now simplify the equation to get:1/(r/2) = 1/v - 1/u2/r = 1/v - 1/u
Also, from the given data, we have :m = v/u
Substituting the value of v/u in terms of m, we get: u/v = 1/m
So, u = v/m Substituting the value of u in terms of v/m in the previous equation, we get:2/r = 1/v - m/v Substituting the given values of r and m in the above equation, we get:2/31.5 = 1/v - 3.4/v Solving for v, we get: v = 22.6 cm Now that we know the distance of the image from the mirror, we can use the mirror formula to find the distance of the object from the mirror.1/f = 1/v - 1/u
Substituting the given values of r and v, we get:1/(31.5/2) = 1/22.6 - 1/u Solving for u, we get :u = 10.15 cm
Therefore, the distance of the mirror from the face is 10.15 cm. The units are centimeters (cm).Answer: 10.15 cm.

Hello it’s one question with 4 parts can you help me pleased. What is the average rate of growth between 2000 and 2015?
Answers
The future size of the city's population is modeled by the equation:
\(P\left(t\right)=54000e^{0.018t}\)Where "t" represents the number of years after the initial year 2000 and 54,000 is the population size during the initial year.
a) To determine if the exponential function is decreasing or increasing, you have to look at the coefficient of the exponent:
\(P\left(t\right)=a*e^{kt}\)If k is positive, the function is increasing its value.
If k is negative, the function is decreasing its value.
In this case, k= 0.018, the coefficient is positive, which means that the function is increasing.
b. You have to determine the size of the population by the year 2002, to calculate this value, the first step is to determine the value of t that corresponds to the year 2002
The initial value t=0 corresponds to the year 2000.
The variable "t" is measured in years, so each unit increase of "t" will represent one year, so that:
The year 2001 corresponds to t=1
The year 2002 corresponds to t=2
To calculate the size of the population you have to use t=2:
\(\begin{gathered} P\left(t\right)=54000e^{0.018t} \\ P\left(2\right)=54000e^{0.018*2} \\ P\left(2\right)=54000e^{0.036} \\ P\left(2\right)=55979.41\cong55979 \end{gathered}\)By 2002 the population will be 55,979.
c. To determine the population by the year 2015, you have to use the value t= 15
\(\begin{gathered} P\left(t\right)=54000e^{0.018t} \\ P\left(15\right)=54000e^{0.018*15} \\ P\left(15\right)=54000e^{0.27} \\ P\left(15\right)=70738.08\cong70738 \end{gathered}\)By 2015 the population will be 70,738.
d. To calculate the average growth rate between 2000 and 2015 you have to apply the following formula.
\(\frac{f\mleft(b\mright)-f\mleft(a\mright)}{b-a}\)Where (b,f(b)) and (a,f(a)) are the ordered pairs of the interval.
For the year 2015 you have to use the values obtained in part c (15,70738).
For the year 2000 you have to use the initial values of the exponential function (0,54000)
\(\begin{gathered} \frac{P\left(15\right)-P\left(0\right)}{15-0} \\ \frac{70738-54000}{15} \\ \frac{16738}{15}=1115.86\cong1116 \end{gathered}\)The average growth year between 2000 and 2015 is 1,116.

for any symbol that can be bound to that variable, a following statement holds. For

Answers
This is a logical symbol, represented by the symbol â, which introduces a variable and asserts that any symbol that can be bound to that variable will satisfy a following statement.
In your example, the variable is "x" and the statement being asserted is "x is red or green". This means that for any apple that can be represented by the variable "x", it will either be red or green. So the statement can be written as: "âx (x is an apple -> x is red or green)" which reads as "for all apples x, x is red or green".
In order to assert that for all apples x, x is red or green using the universal quantifier, we can formulate the statement as follows:
∀x (A(x) → (R(x) ∨ G(x)))
Here's a step-by-step explanation of the statement:
1. "∀x" is the universal quantifier, which introduces the variable 'x' and asserts that the following statement holds for all possible values of 'x'.
2. "A(x)" represents the property of being an apple for the variable 'x'.
3. "R(x)" represents the property of being red for the variable 'x'.
4. "G(x)" represents the property of being green for the variable 'x'.
5. "R(x) ∨ G(x)" represents the disjunction (logical OR) of 'x' being red or green.
6. "A(x) → (R(x) ∨ G(x))" is the statement that if 'x' is an apple, then 'x' is either red or green.
So, the statement ∀x (A(x) → (R(x) ∨ G(x))) asserts that for all apples x, x is red or green.

A farmer had 4/5 as many chickens as ducks. After she sold 46 ducks, another 14 ducks swam away, leaving her with 5/8 as many ducks as chickens. How many ducks did she have left?
Answers
Let's assume the number of ducks the farmer initially had as 'd' and the number of chickens as 'c'.
Given:
The farmer had 4/5 as many chickens as ducks, so c = (4/5)d.
After selling 46 ducks, the number of ducks becomes d - 46.
After 14 ducks swam away, the number of ducks becomes (d - 46) - 14.
The farmer was left with 5/8 as many ducks as chickens, so (d - 46 - 14) = (5/8)c.
Now we can substitute the value of c from the first equation into the second equation:
(d - 46 - 14) = (5/8)(4/5)d.
Simplifying the equation:
(d - 60) = (4/8)d,
d - 60 = 1/2d.
Bringing like terms to one side:
d - 1/2d = 60,
1/2d = 60.
Multiplying both sides by 2 to solve for d:
d = 120.
Therefore, the farmer initially had 120 ducks.
After selling 46 ducks, the number of ducks left is 120 - 46 = 74.
After 14 more ducks swam away, the final number of ducks left is 74 - 14 = 60.
So, the farmer is left with 60 ducks.

There are 9 boys at a summer camp. The ratio
of boys to girls is 1 : 2. How many children are
at the summer camp in total?
Answers
Step-by-step explanation:
If the ratio of boys to girls is 1:2, then for every 1 boy there are 2 girls.
Let's use "x" to represent the number of girls at the summer camp.
So, if there are 9 boys, then the total number of children at the summer camp can be represented as:
9 boys + 2x girls = total number of children
But we don't know what "x" is yet. We can use the ratio to find out.
Since the ratio of boys to girls is 1:2, we know that the number of boys is one-third of the total number of children.
So, we can set up the following equation:
9 = (1/3) * total number of children
To solve for the total number of children, we can multiply both sides by 3:
27 = total number of children
Now we know that there are 27 children at the summer camp in total.
To find the number of girls, we can subtract the number of boys from the total number of children:
27 - 9 = 18
Therefore, there are 18 girls at the summer camp and a total of 27 children.
Answer:The problem involves working out the total number of children at a summer camp, given that there are nine boys and the ratio of boys to girls is 1:2. This problem can be solved using simple ratio and proportion, and basic arithmetic skills.To understand the problem, one needs to know that a ratio is a way of comparing numbers. In this case, the ratio of boys to girl is 1:2, which means that for every one boy, there are two girls.To work out the total children at the summer camp, we need to start by setting up an equation involving the ratio. Let “x” be the number of girls, and “y” be the total number of children in the camp. We know that the ratio of boys to girls is 1:2, so the number of girls is twice the number of boys, that is, x=2(9)=18.Next, we add the number of boys to the total number of children to get y: y = 9 + 18 = 27. Therefore, there are 27 children total at the summer camp.To verify this result, we can check that the ratio of boys to girls is 1:2, which is the same as 9:18. Dividing both sides by 9, we get 1:2, which means that we have worked out the correct answer.In summary, the total number of children at the summer camp is 27. The problem requires the use of ratios as a comparison of numbers, and the use of basic arithmetic skills to calculate the total number of children at the summer camp.
