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).

Write the measurement with the indicated number of significant digits.
982. 1m^2
Using scientific notation, it is found that:
The number is written as follows: [tex]9.821 \times 10^2[/tex] m².The number has 4 significant digits, which are 9, 8, 2 and 1.What is scientific notation?A number in scientific notation is given by:
[tex]a \times 10^b[/tex]
With the base being [tex]a \in [1, 10)[/tex].
For this problem, the number is given by:
982.1 m².
In scientific notation, the base has to be a number between 1 and 10(open interval at 10), hence the base has to be divided by 100.
To compensate for the division by 100, the number has to be multiplied by 100 somewhere, which happens when we add 2 to the exponent, as 10² = 100.
Hence:
The number is written as follows: [tex]9.821 \times 10^2[/tex] m².
The significant digits are all the digits that are not zero, and the zeros at the beginning or between other numbers, hence they are:
9, 8, 2 and 1.
Meaning that the number has 4 significant digits.

A card is selected to from a standard deck of 52 card what are the odds of selecting a red 9
The odds of selecting a red 9 is 1/26.
Probability of an event E is represented by P(E) can be defined as (the number of favorable outcomes) / (Total number of outcomes).
Given the total number of cards in a standard deck = 52
there can be only two red9 as one 9 from heart and one red from diamond.
So the number of outcome for red 9 =2
the probability of odds of selecting red 9 is [tex]\frac{2}{52}[/tex] which can be further simplified into [tex]\frac{1}{26}[/tex].

Aaden took a taxi from his house to the airport. The taxi company charged a pick-up fee of $3.10 plus $2.75 per mile. The total fare was $27.85, not including the tip. Write and solve an equation which can be used to determine x, the number of miles in the taxi ride.
The equation can be written as 2.75x + 3.10 = 27.85
The number of miles in the taxi ride is 9
How to calculate the number of miles in the taxi ride ?The taxi company was charged a pick-up fee of $3.10
It also charges $2.75 per mile
The total fare is $27.85
The equation can be written as
2.75x + 3.10 = 27.85
Collect the like terms to get the value of x
2.75x= 27.85 - 3.10
2.75x = 24.75
divide both sides by the coefficient of x which is 2.75
2.75x/2.75= 24.75/2.75
x= 9
Hence the number of miles in the taxi ride is 9

Step-by-step explanation:
You should understand that numbers are naturally classified as real and imaginary. Under the real numbers, they are additionally classified into rational and irrational numbers. Under rational numbers, these possess fractions and integers. Irrational numbers are in decimal forms that cannot be converted to fractions. Thus, the difference between the two is that: -1.96312.. is a real, irrational number while √(-5) is imaginary. There is no value for a root of a negative number.

At sunset a thermometer had a reading of 4'f during the night the temperature decreased 15'f after the decrease what is the total number of degrees that the temperature must change for the thermometer must read 0'f
If at sunset a thermometer had a reading of 4°F and during the night the temperature decreased by 15°F, then after the decrease the total number of degrees that the temperature must change for the thermometer to read 0°F is equal to 11°F.
The total number of degrees that the temperature must change for the thermometer to read 0°F can be determined by using subtraction.
Subtraction can be defined as an act of calculating the difference between numbers or values.
As the temperature decreased by 15°F during the night, the temperature after the decrease can be calculated as follows,
4°F - 15°F = -11°F
The total number of degrees the temperature must change for the thermometer to read 0°F can be calculated as follows,
-11°F + x = 0
x = 11°F
Hence, the temperature must increase by 11°F for the thermometer to read 0°F.

¿Cuál es el área y el perímetro de un terreno?
En esta pregunta tenemos conocimiento de las ecuaciones asociadas a las longitudes de la base y la altura del terreno, cuya forma es rectangular. Inicialmente, determinamos el área del terreno:
A = b · h
A = (20 - 2 · x) · (16 + 10 · x)
A = (20 - 2 · 3) · (16 + 10 · 3)
A = (20 - 6) · (16 + 13)
A = 14 · 29
A = 406 m²
El área del terreno es igual a 406 metros cuadrados.
Ahora, determinamos el perímetro del terreno:
p = 2 · (b + h)
p = 2 · [(20 - 2 · x) + (16 + 10 · x)]
p = 2 · (8 · x + 36)
p = 16 · x + 72
