In order to find the distance we need to do
[tex]d = \sqrt{(x2 - x1) ^{2} + (y2 - y1) ^{2} } [/tex]
Once we plug x2=5 and x1=-1
and y2=1 and y1= 7
You get
[tex]6 \sqrt{2} [/tex]
Now to find the midpoint:
[tex]( \frac{x1 + x2}{2} \frac{y1 + y2}{2} )[/tex]
Using the same values defined above we get:
(2,4)

An aircraft on a reconnaissance mission takes off from its home base and flies 550 miles at a bearing of S 46° E to a location in the sea. It then flies 483 miles from the sea at a bearing of S 55° W to another location. Finally, the aircraft flies straight back from the second location to its base. What is the total distance it flies, rounded to the nearest mile?
A.
550 miles
B.
1,033 miles
C.
1,583 miles
D.
1,692 miles
E.
2,210 miles
============================================
Explanation:
A diagram is very handy for this type of problem. Refer to the diagram below (attached image). Here are the steps used to form the diagram
Plot point A and make that the home base. Plot point D directly south of point A. I'm skipping B and C because those will be used to form the triangle later.Imagine you are standing at point A and looking south at point D. Turn 46 degrees toward the east direction (this is what the notation "bearing of S 46° E" means). Then move 550 miles from A to land on point B. This is the location where the plane makes its first turn.Plot the points E and F, which are north and south of point B.Imagine we are at point B and looking directly south at point F. Turn 55 degrees toward the west, which is due to the "S 55° W" and then move 483 miles to arrive at point C. This is the plane's location where it turns around to go back to home base.The diagram below shows all of this visually summarized. We have the segments
AB = 550 milesBC = 483 milesAC = x milesAnd we have these angles
Angle DAB = 46 degrees and Angle ABE = 46 degrees (blue)Angle ABC = 79 degrees (red)Angle ACB = 55 degrees and Angle FBC = 55 degrees (green)Angle ABC comes from the fact that the blue and green angles add with the red angle to get 180. So we basically need to solve 46+y+55 = 180 which leads to y = 79.
------------------------------
Once the diagram is set up, we'll use the law of cosines to find x.
Focus on triangle ABC. Ignore points D,E,F. Ignore any extra lines as well.
The interior angles of triangle ABC are
A = 46 degreesB = 79 degreesC = 55 degreesThe sides opposite the angles are
a = 483 (opposite angle A)b = x (opposite angle B)c = 550 (opposite angle C)Now we can apply the law of cosines
b^2 = a^2 + c^2 - 2*a*c*cos(B)
x^2 = 483^2 + 550^2 - 2*483*550*cos(79)
x^2 = 434412.180756441
x = sqrt(434412.180756441)
x = 659.099522649229
x = 659
Side AC, or CA, is roughly 659 miles long.
------------
To find the total distance the plane travels, we add up the three sides of the triangle (ie we find the perimeter)
Distance Traveled = AB + BC + CA
Distance Traveled = 550 + 483 + 659
Distance Traveled = 1692 miles

In rhombus MATH, the coordinates of the endpoints of the diagonal MT are M(0, 2) and T(4, 6). Write an equation of the line that contains diagonal AH. Give your answer in slope-intercept form.
Answer:
y = - x + 6
Step-by-step explanation:
-- Rhombus diagonals are perpendicular and bisect each other.
-- A( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] ) and B( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
Coordinates of the midpoint of a segment AB are
( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )
and formula of a slope of the line segment AB is
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
-- If AB ⊥ CD then [tex]m_{AB}[/tex] × [tex]m_{CD}[/tex] = - 1
-- Slope-point of linear equation is
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
~~~~~~~~~~~~~~~~
M(0, 2)
T(4, 6)
[tex]m_{MT}[/tex] = [tex]\frac{6-2}{4-0}[/tex] = 1
[tex]m_{AH}[/tex] = - 1
Coordinates of the intersection of the diagonals are ( [tex]\frac{4+0}{2}[/tex] , [tex]\frac{6+2}{2}[/tex] ) = (2, 4)
y - 4 = - 1(x - 2)
y = - x + 6 is slope-intercept form of the diagonal AH

Step-by-step explanation:
hope this helps!!!!!!! :D
which is the correct answer?
Step-by-step explanation:
Options B and C are wrong because 0 as a numerator is totally fine as a real solution.
In Option A,
15(x² - 1) = 10(3x - 3)
15x² - 45x + 30 = 0
x² - 3x + 2 = 0
(x - 1)(x - 2) = 0
x = 1 or x = 2.
This is correct as x cannot be 1 (dividing by zero).
In Option D,
(x + 2)(x - 1) = 40
x² + x - 42 = 0
(x - 6)(x + 7) = 0
x = 6 or x = -7.
In here x = 1 does not even appear in our working so it is not an extraneous solution (even though it is dividing by zero)
Hence the answer is A.
Is (-4,2) a solution of 4x+5y<-7
Answer:
(-4,2) is NOT a solution
Step-by-step explanation:
In this question, we have to see if the coordinate is a solution to the inequality.
To do this, plug in and solve:
4(-4) + 5(2) < -7
-16 + 5(2) < -7
-16 + 10 < -7
-6 < -7
Since -6 is not less than -7, this would be false.
Therefore, (-4,2) is NOT a solution.
coordinates are (-4,2)
equation :
[tex]4x + 5y < - 7[/tex]
substituting values of x and y in equation :
[tex]4( - 4) + 5(2)[/tex]
[tex] = - 16 + 10 \\ = - 6 > - 7[/tex]
which is not the required solution as - 6 is greater than -7
therefore (-4,2) is not the solution
Need help ASAP!!
HELP!!!!!
Answer:
Option D
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph attached,
Since, the given line passes through two points (-3, 0) and (0, 2),
Slope of the line = [tex]\frac{2-0}{0-(-3)}[/tex]
= [tex]\frac{2}{3}[/tex]
y-intercept of the line is the point of intersection of the line and y-axis.
Therefore, y-intercept of the line given in the graph is,
y = 2 units
Option D is the answer.
Rolling a 2 on a number cube is
1. likely
2. unlikely
3. as likely as not (50/50)
4. impossible
5. certain
Answer:
2. unlikely
Step-by-step explanation:
The probability of rolling a 2 is 1/6, 0r 0.1666... .
Probabilities and their meanings:
0 - impossible
between 0 and 0.5 - from unlikely to almost as likely as not
0.5 - as likely as not
between 0.5 and 1 - from as likely as not to almost certain
1 - certain
This probability is 0.1666... which is in the category from 0 to 0.5. It is closer to 0 than to 0.5, so although it is not impossible, it is unlikely.
Answer: 2. unlikely

Write the following in point-slope form using the given information: Slope: 2 points
1/15; Point: (3,-5)
Answer:
[tex]y+5 = \frac{1}{15}(x - 3)}[/tex]
Step-by-step explanation:
Given
[tex]m = \frac{1}{15}[/tex] -- Slope
[tex](x_1,y_1) = (3,-5)[/tex] --- Point
Required
Write an equation in point slope form
The point slope form of an equation is:
[tex]y - y_1 = m(x - x_1)[/tex]

Hence, the equation in point slope form is:
[tex]y+5 = \frac{1}{15}(x - 3)}[/tex]
Together, Lee and Joanna have 19 computer games. Joanna has 3 more games than Lee. Write and solve an equation to find the number of games each friend had.
Answer:
L=8 and J=11
Step-by-step explanation:
If Lee is L and Joanna is J we get: L+J=19.
And since Joanna has 3 more than Lee we get: J=L+3
When we substitute J for L+3 we get: 2L+3=19
When we solve we get: L=8
Finally, since J=L+3 we get: J=11

C. N=1 and D. N=4
Answer:
quarterly N = 4
semi-annually N = 2
Monthly N = 12
annually N = 1
Step-by-step explanation:
Given the following compound interest times :
N = number of times interest is compounded per period :
A period is regarded as a whole year.
Interest compounded;
QUARTERLY = Every 4 months per period = 12/3= 4
SEMI ANNUALLY = Every 6 months per period = 12/6 = 2
MONTHLY = Every month = 12 / 1 = 12
ANNUALLY = Every 12 months = 12 /12 = 1

What is the fourth root of -16/81?
Answer:
The fourth root of -16/81, whose result is -0.19, is -0.66.
Step-by-step explanation:
To determine the fourth root of -16/81, you must first perform this mathematical operation, and then perform the radication of the result of it. Thus, the following process must be carried out:
-16 / 81 = X
-0.19 = X
4√0.19 = -X
0.66 = -X
-0.66 = X
Therefore, the fourth root of -16/81, whose result is -0.19, is -0.66.
