explain the steps in finding the midpoint of the points (-1,2) and (3,-6). The state the midpoint
Answer:
(1, -2)
Step-by-step explanation:
midpoint x = (x₁ + x₂) / 2
midpoint y = (y₁ + y₂) / 2
[tex](\frac{-1 + 3}{2} , \frac{2 + -(6)}{2} )[/tex]
= (1, -2)
The midpoint of the points (-1,2) and (3,-6) is (1, -2).
What is Midpoint?
To find the midpoint of numbers, add two numbers and divide by 2.
Given that;
Two points are (-1,2) and (3,-6).
Now,
Let midpoint of the points (-1,2) and (3,-6) is (x, y)
The value of x = (-1 + 3)/2
= 2/2
= 1
And, The value of y = (2 + (-6))/2
= -4/2
= -2.
Thus, The midpoint of the points (-1,2) and (3,-6) is (1, -2).

16. A can in the shape of a cylinder has a diameter of 6 centimeters
and a height of 10 centimeters, which measurement is closest to
the total surface area of the can in square centimeters?
Answer:
surface area = 245.04 cm² (nearest tenth)
Step-by-step explanation:
Surface area of a closed cylinder = [tex]2\pi r^2+2\pi rh[/tex]
Given:
diameter = 6 cm ⇒ radius = 3 cmheight = 10 cm⇒ surface area = 2 × [tex]\pi[/tex] × 3² + 2 × [tex]\pi[/tex] × 3 × 10
= 78[tex]\pi[/tex]
= 245.04 cm² (nearest tenth)

Select the correct answer. Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(7) = -1 B. g(0) = 2 C. g(-4) = -11 D. g(-13) = 20
Answer:
The correct option is;
D. g(-13) = 20
Step-by-step explanation:
The given information are;
The domain of the function, g is given as -20 ≤ x ≤ 5
The range of the function, g(x), is given as -5 ≤ g(x) ≤ 45
g(0) =-2 and g(-9) = 6
Therefore, given that the function increases from -2, to 6 as the input variable decreases from 0 to -9
Therefore, if the variable, x, decrease further, to -13, the function will likely increase further, to about 20, while in the variable, x, increases further, to 7, the function may likely decrease to about -1
Therefore, we can get either;
g(-13) = 20 or g(7) = -1
However, the domain of the function is -20 ≤ x ≤ 5, therefore, 7 is outside the domain, giving g(-13) = 20 as the only statement that could be true
Factor completely x8 − 81. (x4 − 9)(x4 9) (x2 − 3)(x2 3)(x4 − 9) (x2 − 3)(x2 3)(x4 9) (x2 − 3)(x2 − 3)(x4 − 9).
Answer:
(x² - 3)(x² + 3)([tex]x^{4}[/tex] + 9)
Step-by-step explanation:
[tex]x^{8}[/tex] - 81 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
[tex]x^{8}[/tex] - 81
= ([tex]x^{4}[/tex] )² - 9²

Find the size of angle XYZ. Give your answer to 1 decimal point. Z 13cm X 4cm Y
Using the tangent ratio, the size of angle XYZ, to 1 decimal point is: 72.9°
What is the Tangent Ratio?The tangent ratio is given as, tan ∅ = opposite side/adjacent side of a right triangle.
Thus:
∅ = ∠XYZOpposite side = 13 cmAdjacent side = 4 cmThus:
tan (m∠XYZ) = 13/4
m∠XYZ = tan^-1(13/4)
m∠XYZ = 72.9°

Step-by-step explanation:
Chris drove his car to the movie theater. The graph below represents Chris's speed over time, from when he left his house to when he arrived at the theater. At which times did Chris most likely stop at a stoplight? A. time = 3 min, time = 10.5 min, time = 12 min B. time = 2 min, time = 11 min C. time = 0 min, time = 21 min D. time = 1.5 min, time = 6 min, time = 14 min
Answer:
B
Step-by-step explanation:
Stopping at a stoplight means that Chris's speed would be zero on the graph. The times that his speed is zero are times t = 0, t = 2 min, t = 11 min, and t = 21 min. Because the graph shows his speed from the time he left his house (at t = 0) to the time he arrived at the theater (at t = 21 min), the most likely times he stopped at stoplights are times t = 2 min and t = 11 min.

Water is flowing into an inverted cone, of diameter and height 30 cm at a rate of 4 litres per minute. How long, in seconds,
will it take to fill the cone?
1st question : volume to be filled in liter ?
V cone = 1/3 x base area x h
= 1/3 x pi x r² x h
= 1/3 x 3,14 x (30:2)² x 30
= 1/3 x 3,14 x 15² x 30
V cone = 7,065 cm3 ≈ 7 dm3 ≈ 7 liters
then
we know 4 liters .............1 minute
we are looking for 7 liters............. n minute
4 x n = 7 x 1
n = 7/4
n = 1,75 min => = 1 min + 0,75x60 = 1 min and 45 sec

Answer:
the second one
Step-by-step explanation:
Kirsten is trying to find height using the volume of a cylinder formula, V=πr2⋅h . Which of the following would be a good first step in re-arranging the formula to isolate the height? A) divide both sides of the equation by h B) multiply both sides of the equation by r C) divide both sides of the equation by π D) multiply both sides of the equation by h
Answer:
C
Step-by-step explanation:
we want to "isolate" h (height). that means "h" needs to be alone on one side of the equation, and all other factors need to be brought to the other side.
so, yes, we need to divide both sides by all factors of h : pi and r². only then will we have the isolated h on one side.
therefore, dividing both sides by pi is a good first step.
