The coordinates of the point on the directed line segment from (-10, 2) to (-3,-5) that partitions the segment into a ratio of 4 to 3 is (-6,-2).
Given:
we have two points :
(-10, 2) to (-3,-5)
and the ratio which partitions the segment is:
4:3
we are asked to determine the coordinates of the point.
Let the given points (-10,2) be (x₁, y₁) and (-3,-5) be (x₂, y₂) and the ratio be m:n.
Using section formula to find the coordinates:
x = (mx₂ + nx₁)/(m+n)
= {4(-3) + 3(-10)} /(4+3)
= -12-30/7
= -42/7
= -6
y = (my₂ + ny₁)/(m+n)
= {4(-5) + 3(2)} / (4+3)
= -20+6/7
= -14/7
= -2
Therefore, the required point is (-6,-2)

NO LINKS!! Please help me with this graph
=========================================================
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]

Young David, who slew Goliath, experi- mented with slings before tackling the gi- ant. He found that with a sling of length 0.566 m, he could revolve the sling at the rate of 10.7 rev/s. If he increased the length to 0.87 m, he could revolve the sling only 7.7 rev/s.
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
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

is 160,80,40,20 a arithmetic sequence or a geometric sequence or neither
The given sequence160,80,40,20 is the geometric sequence.
In an Arithmetic sequence, the difference between the two consecutive terms is equal.
In a Geometric sequence, the common ratio of the two consecutive terms is equal.
The given sequence is 160, 80, 40, 20
Now,
[tex]T_{1} = 160\\T_{2} = 80\\T_{3} = 40\\T_{4} =20[/tex]
Subtracting the consecutive terms to calculate the common difference,
[tex]d = T_{2} -T_{1} = 80 -160 = -80[/tex]
[tex]T_{3} -T_{4} = 40 -80 = -40[/tex]
So, [tex]T_{2} -T_{1} \neq T_{3} -T_{4}[/tex]
So, the given sequence is not an arithmetic sequence.
Now, Calculating the common ratios,
[tex]r = \frac{T_{2} }{T_{1} } = \frac{80}{160} = \frac{1}{2}[/tex]
and, [tex]r =\frac{T_{3} }{T_{2} } = \frac{40}{80} = \frac{1}{2}[/tex]
Hence, the ratio is the same for consecutive terms.

The equation of the line has a slope of 7 and passes through the point (-8,3) is y = 7x + 59.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values
The general form of a linear equation is the slope(m) and y-intercept (c) is given as
y = mx + c
Slope m =7
y = 7x + c
Substitute, (-8,3)
3 = 7(-8) + c
c = 59
Thus, y = 7x + 59 will be the equation.
Hence "The equation of the line has a slope of 7 and passes through the point (-8,3) is y = 7x + 59".

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?
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

Identify the domain and range of each graph
A rectangle is drawn so the width is 4 inches longer than the height. If the rectangle's diagonal
measurement is 28 inches, find the height.
The height is 17.69 inches.
From the question, we have
Let height= h
width = h+4
diagonal = 28 inches
Using Pythagoras Theorem
28² = h² + (h+4)²
784 = h² +h² +16+8h
784 = 2h² +16+8h
2h²+8h-768 = 0
Solving this, we get
h=−2+2*√97
h=17.69 inches
Multiplication:
Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious. In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.
