The midpoint of the segment as an ordered pair (-6,-1,) (-1,-6)
Answer:
Step-by-step explanation:
(-6,-1) & (-1,-6)
[tex]Midpoint=\left(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2} \right)\\\\\\=\left(\dfrac{-6-1}{2},\dfrac{-1-6}{2} \right)\\\\\\=\left(\dfrac{-7}{2},\dfrac{-7}{2} \right)\\\\\\[/tex]
= (-3.5 , -3.5)
Answer:
[tex]\boxed{\sf{(-3.5 , -3.5)}}}[/tex]
Step-by-step explanation:
This problem must be solved using the midpoint formula, which is similar to a slope formula.
Midpoint formula: [tex]\sf{(X_1,Y_1)}(X_2,Y_2)[/tex]
[tex]\sf{(\dfrac{x_2+x_1}{2},\quad \dfrac{y_2+y_1}{2})}[/tex]
y2=(-6)
y1=(-1)
x2=(-1)
x1=(-6)
Rewrite the problem and then solve it.
[tex]\left(\dfrac{-1-6}{2},\:\dfrac{-6-1}{2}\right)=-\sf{\dfrac{7}{2}, -\dfrac{7}{2}}[/tex]
Dividing is another option.
-7/2=-3.5
(-3.5, -3.5)
As a result, the final answer is (-3.5, -3.5).

What does it mean to integrate a function in calculus?.
Answer:
See below
Step-by-step explanation:
Integrating a function basically means you are taking the inverse of finding a derivative of the function. Integration is used to find the area under a curve or multiple curves, or even volume.
For instance, [tex]\int\limits^ {}2x \, dx=x^2+C[/tex] because the derivative of [tex]x^2[/tex] is [tex]2x[/tex].

Give the following angle of a regular polygon 120, (3x+5), (x), 45, 135, (x-45), and (5x) degrees,
What is the value of x?
What is the degree measure of one central angle of a regular octagon?
The value of x in the heptagon is 64
The measure of one central angle of a regular octagon is 135°
Regular polygon
Regular polygon are polygon that are equiangular. This simply means all the angles are equal.
The regular polygon has 8 angles. Therefore, it is an heptagon.
The sum of internal angle of a regular heptagon is 900 degrees.
Therefore,
120 + 3x + 5 + x + 45 + 135 + x - 45 + 5x = 900
10x = 900 - 120 - 50 - 135 + 45
10x = 640
divide both sides by 10
x = 640 / 10
x = 64
The degree measure of one central angle of a nonagon can be calculated as follows;
sum of angle in a octagon = 1080
central angle = (n - 2)180 / n = 6 × 180 / 8 = 1080 / 8 = 135°

Mr. Odulate’s rectangular classroom has an area of 1,152 square feet. If the width of the room is 36 feet, what is the length of the room?
Answer:
32 feet
Step-by-step explanation:
The area of a rectangle is [tex]a = lw[/tex], where the area equals the length times the width. Since we are given the area and the width, we can divide them to find the width, since it's the inverse operation.
⇒ 1152 ÷ 36 ≈ 32 feet

Answer: Number 5
Step-by-step explanation:
If Jachin needs $400 dollars to get the tablet and she already has $85 she now needs $315. (400 - 85) Since she gets paid $25 a week we have to find how many weeks it will take to reach the $315. So that would be 12.6 weeks. (12.6 x $25 = $315) And she should have no more than 13 weeks to get the money because 12.6 rounded up is 13.
And that should be Answer: Number 5 (w > 12.6 means that it will take Jachin no more than 13 weeks to save enough money to buy the tablet)
Hope that this is not too confusing
Answer:
F. w > 12.6, minimum of 13 weeks
Step-by-step explanation:
The amount Jachin will have in his savings account will be the sum of the initial amount and the product of the weekly deposit and the number of weeks. Jachin wants that amount to be more than $400. The inequality that represents Jachin's desired bank balance is ...
85 +25w > 400 . . . . . initial balance plus deposits total more than $400
25w > 315 . . . . . . . subtract 85
w > 12.6 . . . . . . . divide by 25; solution to the inequality
__
Jachin makes a deposit once a week, so the value of w will be an integer. The requirement that the value of w be greater than 12.6 means it will take at least 13 weeks for Jachin to save more than $400.
_____
Additional comment
We don't know how much more than $400 Jachin needs to save. We only know it is some amount more than $400. Hence, we cannot say that after week 13 when Jachin has a balance of $410 that he can buy the tablet. This means the "no more than ..." answer choices have no basis in the problem statement and must be ignored.
This only leaves the first and last answer choices as being worthy of consideration. The first choice presumes that w may take on a non-integer value. If Jachin makes a deposit once a week, he will not be making a deposit when w = 12.6 weeks. He will be making his deposit when w = 13 weeks.

Connect point S and C for SC= RC.
So, <CSR = <PRS= 36 {Equal sides to equal Angle}
Then, <SCP = <CSR + <PSR
= 36+ 36
= 72
Now, <SCP = <SPC = 1/2 (180- <SCP)

There is a bag filled with 5 blue, 6 red and 2 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 the same colour?
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Let's separate into 3 cases:
Note that we put the number of color balls we want in the numerator and the total number of color balls remaining in the denominator.
Case 1: 2 blue marbles
[tex]\frac{5}{13} * \frac{4}{12} = \frac{5}{39}[/tex]
(There were 5 blues originally, and 4 blues after 1 blue is taken out, same logic but different colors and values in case 2 and 3.)
Case 2: 2 red marbles
[tex]\frac{6}{13} * \frac{5}{12} = \frac{5}{26}[/tex]
Case 3: 2 green marbles
[tex]\frac{2}{13} * \frac{1}{12} = \frac{1}{78}[/tex]
Now add up all 3 cases and you will have the probability as required.
[tex]\frac{5}{39} +\frac{5}{26}+ \frac{1}{78} = \frac{1}{3}[/tex]
one of the angle measures in an isosceles triangle is 40 degrees what could the other two angle measures be
Answer:
B and E
Step-by-step explanation:
An isosceles has two congruent (equal) angles and all of the angles add up to 180.
In option B, there are 2 congruent angles (70 and 70), and all the angles add up to 180 (70+70+40=180).
In option E there are 2 congruent angles (40 and 40), and all of the angles also add up to 180 (40+40+100=180).
The rest of the options do not fit the criteria for an isosceles triangle.
