Which is the midpoint of the segment joining (12, 2) and (-5, – 7)?
Answer:
[tex]m(x, y)=(\frac{7}{2} , -\frac{5}{2} )[/tex]
Step-by-step explanation:
Midpoint of line segment is calculated as
[tex]m(x, y)=(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )[/tex] -----------(1)
Here
[tex](x_1, y_1) = (12,2) \ \ and \ \ (x_2, y_2) = (-5, -7)[/tex]
Substituting values in equation (1)
[tex]m(x, y)=(\frac{12-5}{2} , \frac{2-7}{2} )[/tex]
[tex]m(x, y)=(\frac{7}{2} , -\frac{5}{2} )[/tex]
which rule best described the following pattern 8,4,10,6,12,8,14
Answer:
-4 and +6
Step-by-step explanation:
The sequence follows a pattern of subtracting 4 then adding 6.
8 - 4 = 4 + 6 = 10 - 4 = 6 + 6 = 12 - 4 = 8 + 6 = 14

find the values of m &n .. please help !!
Answer:
m = 12.728 or 18/root (2)/2, n = 9
Step-by-step explanation:
To find m, we can use sin(45) and cos(45).
Since sin(45) = root (2)/2 and this equals 9/m.
We set the equation root (2)/2 = 9/m and solve for m.
9 divided by root (2)/2 would give us 18/root (2), or 12.728.
m is 12.728.
Same process for n but we are using cosine this time.
cos(45) = root (2)/2 and this equals n/12.728.
Solving for n would give us root (2)/2 times 12.728.
This gives us that n is 9.

what are the coordinates of the x-intercept of the graph?
a. (-6,0)
b. (0,-6)
c. (9,0)
d. (0,9)
Answer:
d. (9, 0)
Step-by-step explanation:
(x, y) so...
Where the line crosses the x-plane, x = 9
Since this is the x-intercept y will always equal zero
Therfore x-int = (9, 0)

We are Given:_______________________________________________
ΔABC right angled at B
BC = 8
AC = 20
Part A:_____________________________________________________
Finding the length of AB
From the Pythagoras theorem, we know that:
AC² = BC² + AB²
replacing the given values
(20)² = (8)² + AB²
400 = 64 + AB²
AB² = 336 [subtracting 64 from both sides]
AB = 18.3 [taking the square root of both sides]
Part B:_____________________________________________________
Finding Sin(A)
we know that Sin(θ) = Opposite / Hypotenuse
The side opposite to ∠A is BC and The hypotenuse is AC
So, Sin(A) = BC / AC
Sin(A) = 8/20 [plugging the values]
Sin(A) = 2/5
Part C:_____________________________________________________
Finding Cos(A)
We know that Cos(θ) = Adjacent / Hypotenuse
The Side adjacent to ∠A is AB and the hypotenuse is AC
So, Cos(A) = AB / AC
Cos(A) = 18.3/20 [plugging the values]
Cos(A) = 183 / 200
Part D:_____________________________________________________
Finding Tan(A)
We know that Tan(θ) = Opposite / Adjacent
Since BC is opposite and AB is adjacent to ∠A
Tan(A) = BC / AB
Tan(A) = 8 / 18.3 [plugging the values]
Tan(A) = 80 / 183
Answer:
by using Pythagoras law
ac²=ab²+bc²
20²=ab²+8²
ab²=20²-8²
AB=√336=18.33
Step-by-step explanation:
sin a=p/h=8/20=2/5
cos a =b/h=18.33/20
tana =p/b=8/18.33

What name is given to each of the following angles?
a) An angle of exactly 90 degrees
b) An angle between 90 degrees and 180 degrees
c) An angle less than 90 degrees
d) An angle between 180 degrees and 360 degrees
Answer:
Step-by-step explanation:
a) Right angle
b) Obtuse
c) Acute
d) Reflex angle.
Thank you
The name of the angles are as follows:
1) x = 90 degrees: Right angle.
2) 90 < x < 180: Obtuse angle.
3) 90 > x : Acute angle.
4) 180 < x < 360 : Reflex angle.
Given,
Category of angles.
Now,
1)
Right angle : An angle of exactly 90 degrees.
x = 90 degrees
2)
Obtuse angle :
An angle between 90 degrees and 180 degrees.
90 < x < 180
3)
Acute angle:
An angle less than 90 degrees.
90 > x
4)
Reflex angle:
An angle between 180 degrees and 360 degrees.
180 < x < 360

What is the value of x
Answer:
X = 56 degrees
Step-by-step explanation:
Angles D and F are equivalent. Because the three angles must add up to 180 degrees, you must add 112 to 68 in order to reach 180. Then you must divide this in half, getting 56 degrees as your answer.
180 - 68 = 112
112/2 = 56
X=56

Answer:
y = (1/3)x
Step-by-step explanation:
1) Use the slope formula: (y2-y1)/(x2-x1) and then substitute both points into the formula. That should give you (2-0)/(6-0) = 2/6 = 1/3.
1/3 would then be your slope
2) Since the y intercept is (0,0), the y-intercept isn't needed in the slope intercept equation
So that would give you y = (1/3)x

Carmen is writing an article for a magazine. She will be paid a flat fee and also will be paid for each word that is published. The total amount she can expect to be paid, in dollars, can be estimated using the function f(x) = 2.5x + 150 . where s is the number of words published . What is the inverse of this function?
Step-by-step explanation:
Given Function
f(x) = 2.5x + 150
f^-1(x) = ?
Let y = f(x)
y = 2.5x + 150
Interchanging the role of x and y we get,
x = 2.5y + 150
x - 150 = 2.5y
y = (x - 150) / 2.5
So therefore
f^ -1(x) = (x - 150) / 2.5
Hope it will help :)

At the rodeo, 256 hot dogs were sold for a total of $768. If each hot dog sold for the same amount, what would be the cost of 24 hot dogs?
Answer:
$72
Step-by-step explanation:
$768/265 = $3
$3 x 24 = $72
Answer:
$72
Step-by-step explanation:
768/256 = how much each hot dog was sold for
768/256 = 3
Each hot dog was sold for $3.
