Explanation:
The three points are at these locations:
A = (10, 6)B = (1,-3)C = (-5, 3)The notation "d(A,C)" means "the distance from A to C". It's equivalent to saying "the length of segment AC".
Then writing [tex]\left[d(A,C)]^2[/tex] means we'll square that distance.
Use the distance formula to get...
[tex]A = (x_1,y_1) = (10,6) \text{ and } C = (x_2, y_2) = (-5,3)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(10-(-5))^2 + (6-3)^2}\\\\d = \sqrt{(10+5)^2 + (6-3)^2}\\\\d = \sqrt{(15)^2 + (3)^2}\\\\d = \sqrt{225 + 9}\\\\d = \sqrt{234}\\\\[/tex]
This is the exact length of segment AC. That value squares to 234.
[tex]d = \sqrt{234} \ \to \ d^2 = (\sqrt{234})^2 = 234\\\\[/tex]
The square root and squaring operation cancel each other out. Think of it like fire vs water.
So we really only care about what's under the square root; rather than the entire square root expression itself. Which is nice because we don't have to worry about pesky things like decimal values.
This is why 234 is typed into the first box.
---------------------
Next, use the distance formula to find how far it is from A to B. Square the result to get what you see below.
[tex]A = (x_1,y_1) = (10,6) \text{ and } B = (x_2, y_2) = (1,-3)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(10-1)^2 + (6-(-3))^2}\\\\d = \sqrt{(10-1)^2 + (6+3)^2}\\\\d = \sqrt{(9)^2 + (9)^2}\\\\d = \sqrt{81 + 81}\\\\d = \sqrt{162}\\\\d^2 = (\sqrt{162})^2\\\\d^2 = 162\\\\[/tex]
This is the value of [tex]\left[d(A,B)\right]^2[/tex]
Now find the distance from B to C, and square the result.
[tex]B = (x_1,y_1) = (1,-3) \text{ and } C = (x_2, y_2) = (-5,3)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-(-5))^2 + (-3-3)^2}\\\\d = \sqrt{(1+5)^2 + (-3-3)^2}\\\\d = \sqrt{(6)^2 + (-6)^2}\\\\d = \sqrt{36 + 36}\\\\d = \sqrt{72}\\\\d^2 = \left(\sqrt{72}\right)^2\\\\d^2 = 72\\\\[/tex]
Add this to the previous squared value and we get 162+72 = 234, which matches exactly with the 234 found up toward the top.
We'll write 234 in the 2nd box as well.
This shows that [tex]\left[d(A,C)\right]^2 = \left[d(A,B)\right]^2+\left[d(B,C)\right]^2[/tex] is a true statement. By the converse of the Pythagorean theorem, we have confirmed this is a right triangle.
In other words, we've shown that [tex]a^2+b^2 = c^2[/tex] is a true statement (a,b,c are the sides of the right triangle such that c is the hypotenuse).
---------------------
Recall that we found these segment lengths:
[tex]AB = \sqrt{162} = \text{leg1}\\\\BC = \sqrt{72} = \text{leg2}\\\\AC = \sqrt{234} = \text{hypotenuse}\\\\[/tex]
The legs of a right triangle represent the base and height, in either order. This is because the legs are perpendicular to one another. They form a right (aka 90 degree) angle.
[tex]\text{area} = \frac{1}{2}*\text{base}*\text{height}\\\\\text{area} = \frac{1}{2}*\text{AB}*\text{BC}\\\\\text{area} = \frac{1}{2}*\sqrt{162}*\sqrt{72}\\\\\text{area} = \frac{1}{2}*\sqrt{162*72}\\\\\text{area} = \frac{1}{2}*\sqrt{11664}\\\\\text{area} = \frac{1}{2}*108\\\\\text{area} = 54\\\\[/tex]

[tex][d(A,B)]^2+[d(B,C)]^2=\boxed{234}[/tex]
[tex]\sf Area=\boxed{54}\; units^2[/tex]
Step-by-step explanation:
From inspection of the given diagram:
A = (10, 6)B = (1, -3)C = (-5, 3)If ΔABC is a right triangle, the sum of the squares of the two shorter sides will equal the square of the longest side. This is the definition of Pythagoras Theorem.
Use the distance formula to find the length of each side of the triangle.
[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Distance between two points}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two points.\\\end{minipage}}[/tex]
[tex]\begin{aligned}d[(A,C)]&=\sqrt{(x_C-x_A)^2+(y_C-y_A)^2}\\&=\sqrt{(-5-10)^2+(3-6)^2}\\&=\sqrt{(-15)^2+(-3)^2}\\&=\sqrt{225+9}\\&=\sqrt{234}\end{aligned}[/tex]
[tex]\begin{aligned}d[(A,B)]&=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\&=\sqrt{(1-10)^2+(-3-6)^2}\\&=\sqrt{(9)^2+(-9)^2}\\&=\sqrt{81+81}\\&=\sqrt{162}\end{aligned}[/tex]
[tex]\begin{aligned}d[(B,C)]&=\sqrt{(x_C-x_B)^2+(y_C-y_B)^2}\\&=\sqrt{(-5-1)^2+(3-(-3))^2}\\&=\sqrt{(-6)^2+(6)^2}\\&=\sqrt{36+36}\\&=\sqrt{72}\end{aligned}[/tex]
Therefore:
The longest side of the triangle is line segment AC.The two shorter sides of the triangle are line segments AB and BC.[tex]\boxed{\begin{minipage}{9 cm}\underline{Pythagoras Theorem} \\\\$a^2+b^2=c^2$\\\\where:\\ \phantom{ww}$\bullet$ $a$ and $b$ are the legs of the right triangle. \\ \phantom{ww}$\bullet$ $c$ is the hypotenuse (longest side) of the right triangle.\\\end{minipage}}[/tex]
Therefore, the triangle is a right triangle if:
[tex][d(A,B)]^2+[d(B,C)]^2=[d(A,C)]^2[/tex]
Substitute the found side lengths into the formula:
[tex]\implies [\sqrt{162}]^2+[\sqrt{72}]^2=[\sqrt{234}]^2[/tex]
[tex]\implies162+72=234[/tex]
[tex]\implies 234=234[/tex]
Hence proving that ΔABC is a right triangle.
To find the area of a right triangle, half the product of the two shorter sides:
[tex]\begin{aligned}\implies \sf Area &= \dfrac{1}{2}bh\\&=\dfrac{1}{2} \cdot [d(A,B)] \cdot [d(B,C)]\\&=\dfrac{1}{2} \cdot \sqrt{162} \cdot \sqrt{72}\\&=\dfrac{1}{2} \cdot \sqrt{162 \cdot 72}\\&=\dfrac{1}{2} \cdot \sqrt{11664}\\&=\dfrac{1}{2} \cdot \sqrt{108^2}\\&=\dfrac{1}{2} \cdot 108\\&=54 \sf \; units^2\end{aligned}[/tex]
A rare coin increases in value according to the function f(x)=100(1.07)x
f(x)=100(1.07)x where x represents the amount of years that the coin is owned and value is measured in US dollars. What is the value of the coin after 5 years?
Answers
The value of the coin after five years is 535 when the value increases with the function f(x) = 100(1.07)x
The value of a rare coin rises in accordance with the function f(x)
f(x) = 100(1.07)x
where x represents the number of years that the coin is owned and value is measured in US dollars
Now, Simplifying the given function, we have :
f(x) = 100(1.07)x
f(x) = 107x
Now, we need to find the value of the coin after five years, then
Putting x = 5 in the function,
f(x) = 107 * 5 = 535
Hence, the value of the coin after five years is 535 when the value increases with the function f(x) = 100(1.07)x

Answers
The different ways that are there of selecting the trucks and the drivers to meet these requests is 240 ways.
How to calculate the number of ways?Combinations are also referred to as selections. Combinations imply the selection of things from a given set of things. In this case, we intend to select the objects.
Combination formula
ⁿCr = n! / ((n – r)! r!)
n = the number of items.
r = how many items are taken at a time.
The number of ways to select 3 trucks will be:
= ⁵C₃ = 10
The number of ways to select 3 drivers will be:
= ⁴C₃ = 4
Number of ways to arrange them = 3! = 3 × 2 = 6
Therefore the total number of ways will be:
= 10 × 4 × 6

y=-3x
y=3x
y=3x+1

Answers
Answer: y=3x
Step-by-step explanation:
The equation can be found by finding the slope of the given line. Visually, this can be found by counting the distance between two points. From (1,3) and (2,6), the line "rises" 3 units and "runs" 1 unit to the right. Since slope is calculated as rise over run, this gives us 3/1, or just 3 for slope. In slope-intercept form, this becomes y=3x.
Just to note, we know it is not negative because of the direction of the slope. Visually, if the slope "moves" in the direction of upwards and to the left, it will be positive. This can be calculated more accurately using the slope formula (y2-y1/x2-x1)

a) What is the larger of the two linear speeds?Answer in units of m/s.
part 2
b) Using the sling length 0.87 m, what is the centripetal acceleration at 7.7 rev/s?
Answer in units of m/s2.
this is physics
Answers
The 0.566 meter, 0.87 meter, 10.7 rev/s and 7.7 rev/s radii and respective rotational speeds of young David's slings indicates.
a) The larger linear speed is 42.09 m/s
b) The centripetal acceleration of the sling at 7.7 rev/s is approximately 2,036.39 m/s²
What is a linear speed?A linear speed is a measure of the rate at which the distance traveled by an object in rotary motion changes with time.
When the length of the sling = 0.566 m, The rate of revolving of the sling = 10.7 rev/s
When the length of sling = 0.87 m, the rate of revolving the sling = 7.7 rev/s
Linear speed = Angular speed ×Radius length
The angular speed when the length of the is 0.566 m, ω₁, is found as follows;
One complete 360° rotation = 2·π radians
ω₁ = 10.7 rev/s × 2·π ≈ 67.23 rad/s
The linear speed is; v₁ ≈ 67.23 rad/s × 0.566 m ≈ 38.05 m/s
The angular speed when the length is increased to 0.87 meters is therefore;
ω₂ = 7.7 rev/s × 2 × π ≈ 43.38 rad/sec
The linear speed is; v₂ ≈ 43.38 rad/s × 0.87 m ≈ 42.09 m/sThe larger of the two linear speed is approximately 42.09 m/s
Part 2: The centripetal acceleration, [tex]a_c[/tex], is found using the following formula;
[tex]a_c = \dfrac{v^2}{r}[/tex]
When the radius is r = 0.87 meters, the linear speed v₂ ≈ 42.09 m/s, which indicates;
[tex]a_c=\dfrac{42.09^2}{0.87} \approx 2,036.39[/tex]
The centripetal acceleration is approximately [tex]a_c[/tex] ≈ 2,036.39 m/s²

In a garden club, 90% is ladies. The number of ladies is 12 more than 3 times the number of gentlemen.
How many ladies and how many gentlemen are in the club?
(Note: set up a rational equation and solve)
Answers
The numbers of ladies and gentlemen in the club are 2 and 18 respectively.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100
Given that, there are 90% of ladies in the club, and the number of ladies is 12 more than 3 times the number of gentlemen.
Let the number of gentlemen is x and the number of ladies be y.
Since the number of ladies is 12 more than 3 times the number of gentlemen, it follows:
Calculationy = 12 + 3x (1)
Now, the total number of members in the club is:
x + y
Since there are 90% ladies in the club, it follows:
90%(x + y) = y
90(x + y)/100 = y
90x + 90y = 100y
90x = 100y - 90y
90x = 10y
9x = y (2)
Now, substitute y = 9x into equation (1):
9x = 12 + 3x
9x -3x = 12
6x = 12
x = 2
Substitute x = 2 into equation (2):
9(2) = y
18 = y
Hence, the numbers of ladies and gentlemen in the club are 2 and 18 respectively.

The set of side lengths that would not create a triangle is; 10, 20, 30.
Which set of side lengths will not create a triangle?It follows from the task content that the set of side lengths which will not create a triangle are to be determined from the given task content.
Since the triangle inequality theorem states that; the sum of two side lengths of a triangle is always greater than the third side length and also, the difference of two side lengths of a triangle is less than the third side length.
On this note, for a triangle with side-lengths a, b and c; the inequalities which hold are;
a + b > c and a - b < c.
Therefore, the set of side-lengths which will not create a triangle is; 10, 20, 30.

Number graph ranging from negative four to four on the x and y axes. A line is drawn on the graph that passes through begin ordered pair negative one comma four end ordered pair and begin ordered pair one comma negative two end ordered pair
Answers
The linear equation shown in the graph is the one in the third option.
y + 2 = -3*(x - 1)
What is the equation graphed?Here we have a graph, and there we can see a linear equation, on that graph, we can see that:
The y-intercept is y = 1.
For each horizontal unit, the line goes 3 units down, then the slope is -3.
Then the linear equation is:
y = -3*x + 1
If now we add 2 in both sides, we get:
y + 2 = -3x +1 + 2
y + 2 = -3x + 3
y + 2 = -3*(x - 1)
So the correct option is the third one.

Oliver saves %10 of their weekly earnings for living expenses. oliver usually makes $520 each week. This week oliver made %10 more. incorrectly oliver claims that has $520 left for spending money this week. Calculate the amount of spending money left for this week. What error did olive likely make?
Answers
Oliver is left with $514.8
A percentage is a number or ratio expressed as a fraction of one hundred. If we need to calculate a percentage of a number, divide it by the whole and multiply by 100. As a result, the percentage represents one part in a hundred. The term % stands for one hundred percent.
His usual salary = $520 per week
This week he earned = Usual salary + 10% of usual salary
10% of usual salary =520 x (10/100)
Thus, this week's earnings = $520 + $52 = $572
Amount spent = 10% of this week =572 x (10/100)
= 57.2
Thus, the left amount is calculated by:
Left amount = this week's salary - the amount spent
Amount left = $572 - $57.2 = $514.8
Thus, Oliver is left with $514.8
