The coordinates of the point P is P(x, y) = (- 1, - 10 / 7). (Correct choice: B)
How to determine the coordinates of a resulting point by weighted averages approach
In this problem we find the coordinates of two points on Cartesian plane, of which we must determine the location of a third point by using a formula based on a weight average-like formula:
P(x, y) = (4 / 7) · A(x, y) + (3 / 7) · B(x, y)
P(x, y) = (4 / 7) · (- 4, 2) + (3 / 7) · (3, - 6)
P(x, y) = (- 16 / 7, 8 / 7) + (9 / 7, - 18 / 7)
P(x, y) = (- 7 / 7, - 10 / 7)
P(x, y) = (- 1, - 10 / 7)
The coordinates of the point P is P(x, y) = (- 1, - 10 / 7).

Determine whether following set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer.
8,15,17
The following set of numbers, 8, 15, and 17, can be the measures of the sides of a triangle, specifically a right triangle.
To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.
let a = 8, b = 15, and c = 17
a + b > c 8 + 15 > 17 23 > 17 True
a + c > b 8 + 17 > 15 25 > 15 True
b + c > a 15 + 17 > 8 32 > 8 True
To know what type of triangle based on the length of its side:
1. Take the sum of the squares of the two smaller sides.
8^2 + 15^2 = 289
2. Compare it to the square of the largest side.
17^2 = 289
289 = 289
If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.
if they are equal, it is a right triangle
if they are smaller, then it is an obtuse triangle.
Hence, 8, 15, and 17 can be the measure of the sides of a right triangle.

You decide to race your best friend around the track to see who's the better runner. You travel 400 meters in 8.2 seconds. Your best friend covers the same distance but does it in 7.8 seconds. Calculate the speed of each of you, and determine who is the father runner.
The best friend is the faster runner as his speed is 51.28 m/s while my speed is 48.78 m/s.
Speed is defined as the distance travelled by someone or something in unit time. The SI unit of speed is meters per second. The speed is calculated by dividing the distance travelled by the total time taken to travel said distance.
Given the distance travelled by both of the friends is 400 meters.
Now The first friend travels this distance in 8.2 seconds:
Therefore speed is calculated by distance ÷ time
or, speed = 400 ÷ 8.2
or , speed = 48.7804... m/s
or, speed ≈ 48.78 meters per second
And the best friend travels this distance in 7.8 seconds:
Therefore speed is calculated by distance ÷ time
or, speed = 400 ÷ 7.8
or , speed =51.2820... m/s
or, speed ≈ 51.28 meters per second
Therefore by comparing both the speeds we can conclude that the best friend is the faster runner.

Show some work:
The range of each amazon box is 1.6035m
According to the question we have been given that
height of the conveyer belt = 1.4m
Speed of the belt = 3m/s
We need to find the range of the amazon box, that is we have to find the distance.
Formula for distance is , d = speed * time
We have been given the value of speed we need to find the value of time. For that we will use the formula,
h = [tex]\frac{1}{2} g t^{2}[/tex]
where, h = height
g = acceleration due to gravity = 9.8m/s²
t = time
Putting the required value for t we get,
t = [tex]\sqrt{\frac{2h}{g} } \\[/tex]
= [tex]\sqrt{\frac{2(1.4)}{9.8} } \\[/tex]
= √0.286

F. 25
G. 30
H. 35
J. 40
The correct option is F. 25.
The total number of gallons of gas Amanda will use to travel all the distances is 25.
What is defined as distance?The amount of between two things, or the state of being far apart, is defined as distance. A five-foot distance between two tables is an example of distance. The difference of the two sides of an issue is an example of distance.
Now, as per the given question;
Amanda plans to drive 160 miles, 235 miles, 185 miles, and 220 miles.
Thus, the total distance ravelled by Amanada is;
= 160 miles + 235 miles + 185 miles + 220 miles
= 800 miles
Amanada's car has the average of 32 miles per gallon of gas.
Thus, the car will cover a total of 32 miles for each gallon of gas.
Thus,
The number of gallon of gas requires = Total distance/(distance travelled for one gallon of gas)
The number of gallon of gas requires = 800/32
The number of gallon of gas requires = 25
Therefore, the gas required to travel a total distance of 800 miles is 25 gallons.

Can someone please help me I don’t understand and it’s a really important homework
Answer:
The large box weighs 18.75 and the small box weights 15.75
Step-by-step explanation:
We are looking to find 2 variables so we will need two equations.
Let l = the large box weight
Let s = the small box weight
7l + 9s + 273 5l +3s = 141
I want to add these two equations together and have one of the variables be eliminated. The way both equations are written now, neither variable will drop out. I see that 9 is a multiple of 3. If I multiply the second equation all the way through by - 3, the s variable will be eliminated.
-3(5l +3s) -3(141) Multiple everything by -3
-15l -9s = -423 Now I will add this to the original equation 7l + 9s = 273
7l + 9s = 273
-8l = -150 Divide both sides by -8
l = 18.75 This is the weight of the large box.
Plug in 18.75 to either of the ordinal equations to find the weight of the small box.
5l + 3s = 141
5(18.75) + 3s = 141 Distribute the 5
93.75 + 3s = 141 Subtract 93.75 from both sides
3s = 47.25 Divide both sides by 3
s = 15.75
Check:
Plug in 15.75 for s and 18.75 for l into both of the original equation to see if they equal.
7l + 9s = 273
7(18.75) + 9(15.75) =273
131.25 + 141.75 = 273 Checks
5l + 3s = 141
5(18.75) + 3(15.75) = 141
93.75 + 47.25 = 141
141 = 141 Checks
Write each arithmetic series in summation notation. 1+5+9+. . . . . +41+45
The arithmetic series 1+5+9+. . . . . +41+45 can be expressed in summation notation as [tex]\sum\limits^{12}_{n=1} {(4n-3)}[/tex]
The given arithmetic series:
1+5+9+. . . . . +41+45
To write the series in summation notation:
Find the common difference (d) of the series.
d = 5 - 1 = 4
Recall the formula for the nth term in an arithmetic sequence:
a(n) = a(1) + (n-1) . d
Substitute a(1) = 1 and d = 4:
a(n) = 1 + (n-1) . 4
a(n) = 4n - 3
Find n that leads to a(n) = 45
a(n) = 4n - 3
45 = 4n - 3
4n = 48
n = 12
Thus, the lower limit of the summation is n =1, and the upper limit is n = 12
Now write in summation notation as:
[tex]\sum\limits^{12}_{n=1} {a(n)}= \sum\limits^{12}_{n=1} {(4n-3)}[/tex]
This summation notation can be further simplified using the properties of summation operator:

Using the absolute value function, linear functions and translations, we have that:
9. Vertex (2, 0), Range: {y | 0 ≤ y < ∞}
10. The equation is f(x) = -5x + 100.
11. The correct option is: The slope of f(x) is greater than the slope of g(x).
12. h(-5) = 10.
13. The equation is f(x) = 2x + 5.
14. The graph of y = f(x) will shift right 9 units.
What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0, and has vertex(turning point) at (0,0). The range is from the y-coordinate of the vertex to positive infinity.
In item 9, from the table, the turning point is at (2,0), hence:
Vertex (2, 0), Range: {y | 0 ≤ y < ∞}
What is a linear function?A linear function is modeled by the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.For item 10, we have that:
The initial amount is of 100 patients, as 75 + 25 x 5 = 100 hence b = 100.The reduction is of 5 patients in a week(25 patients reduction in 5 weeks = 5 a week), hence m = -5.Then:
The equation is f(x) = -5x + 100.
For item 11, the slope is given by change in y divided by change in x, hence:
f(x): (1 - (1))/(3 -0) = 2/3 = 0.67.g(x) = (4 - 2)/(5 - 0) = 0.4.Hence:
The correct option is: The slope of f(x) is greater than the slope of g(x).
For item 12, we have that:
h(x) = -4x - 10.
Hence, when x = -5:
h(-5) = -4(-5) - 10 = 20 - 10 = 10.
Hence:
h(-5) = 10.
For item 13, we have that when x changes by 4, y changes by 8, hence the slope is:
m = 8/4 = 2.
When x = 1, y = 7, hence, considering the slope, when x = 0, y = 5, and:
The equation is f(x) = 2x + 5.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.
For this problem, the rule is given by:
y = f(x - 9).
The translation is x -> x - 9, hence:
The graph of y = f(x) will shift right 9 units.

The height of a triangle is three feet less than its base. If the area of the triangle is 275 square feet, find its base and height.
The base and height of triangle are 25 and 22 feet.
We are given the relation between base and height of triangle. Let us represent height with h and base with b. The equation relating the two quantities is as follows -
h = b - 3
Now, the area of triangle is given by the formula -
Area = 1/2 × base × height
Keep the values in formula to find the base of triangle
275 = 1/2 × b × (b-3)
550 = b × (b-3)
b² - 3b - 550 = 0
b² + 22b - 25b - 550 = 0
b (b + 22) -25 (b + 22) = 0
(b + 22) (b - 25) = 0
b = -22 and 25
As the value of base can not be negative, so, the base of triangle is 25 feet.
Calculating height of triangle-
Height = Base - 3
Height = 25 - 3
Height = 22 feet
Hence, the base and height of triangle are 25 and 22 feet.

Given two terms of each arithmetic sequence, find a₁ and d . a₃=32 and a₇ =-8
The common difference d is 6 and the first term a1 is 20.
How to find the a1 and d?The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same value.
The formula of Arithmetic progression is
a(n) = a1 + (n - 1)d
given that the two terms of arithmetic sequence,
a3 = 32 and a7 = -8.
now, find the common difference d.
a(n) = a1 + (n - 1)d
Let take a(n) = a7 and a1 = a3.
a7 = a3 + (7 - 3)d
a7 = a3 + 4d
now substitute the values of a6 and a4
-8 = 32 + 4d
-8 + 32 = 4d
d = 24/4
d = 6
so, the common difference d is 6.
then, find the term a1.
take the formula
a(n) = a1 + (n - 1)d
now, substitute a(n) = a3 and d = 6.
32 = a1 + (3-1)d
32 = a1 + 2d
32 = a1 + 2(6)
32 = a1 + 12
a1 = -12+32
a1 = 20.
so, the first term a1 is 20.
Hence, the common difference d is 6 and the first term a1 is 20.
