If segment RS has endpoint R(-4,-6) and midpoint M(3,-4) what is point S
Based on the calculations using the midpoint rule, the value of point S is equal to (10, 12).
What is a line segment?A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.
How to determine the other endpoint?In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).
Midpoint on x-coordinate is given by:
xm = (x₁ + x₂)/2
3 = (-4 + x₂)/2
Cross-multiplying, we have:
6 = -4 + x₂
x₂ = 6 + 4
x₂ of S = 10.
Midpoint on y-coordinate is given by:
ym = (y₁ + y₂)/2
3 = (-6 + y₂)/2
Cross-multiplying, we have:
6 = -6 + y₂
y₂ = 6 + 6
y₂ of S = 12.
Therefore, point S is equal to (10, 12).

How common is LSD use among high school seniors?LSD use among secondary school understudies is a specific concern. In excess of 8% of secondary school seniors in the United States utilized the medication something like once in the course of their life, and almost 4% involved the medication in the previous year, as per the University of Michigan's Monitoring the Future Survey. In spite of the fact that by the 1980s LSD use had extraordinarily declined, it made a resurgence during the 1990s, basically among teens. An overview led by Monitoring the Future Study discovered that 13.6 percent of 1997's secondary school seniors had tried different things with LSD no less than once contrasted with just 7.2 percent in 1986.

John who is 5 ft tall is standing 20 feet away from a tree, and you measure the angle of elevation to be 38∘. How tall is the tree? Find your answer to the nearest tenth
Answer:
The tree is 20.6 ft tall.
Step-by-step explanation:
Please check the attached graph.
From the diagram, it is clear that John is 5 ft tall is standing 20 feet away from a tree, making an angle of elevation to be 38⁰.
The diagram makes a right-angled triangle.
Given the angle = Ф = 38⁰Adjacent = a = 5 ftOpposite = b = 20 ftHypotenuse = Tree length = c ?Pythagorean Theorem:
For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:
[tex]\:c=\sqrt{a^2+b^2}[/tex]
substituting a=5, b=20
[tex]c=\sqrt{5^2+20^2}[/tex]
[tex]c=5\sqrt{17}[/tex]
[tex]c=20.6[/tex] ft
Thus, the tree is 20.6 ft tall.

Answer:
p = - 2x + 54
Step-by-step explanation:
The price-demand linear equation is
p = mx + b
which is the equation of a straight line in slope-intercept form
The parameters here are m = slope and b = y-intercept in line equation terms
x is the number of shirts sold and p is the price
Using values given, we can generate two equations which can solve for the parameters of the linear equation
To sell 10 shirts, the price has to be $34
==> 34 = m x 10 + b = 10m + b
Switch sides to get 10m + b = 34 (1)
To sell 20 shirts, the price has to be $14
==> 14 = 20m + b
Switch sides to get 20m + b = 14 (2)
Subtract (2) from (1) to eliminate the term b
(1) - (2)
==> 10m+b - (20m+b) = 34 - 14
==> 10m + b - 20m - b = 20
==> 10m - 20m = 20
==> - 10m = 20
==> m = 20/(- 10) = - 2.4
==> m = - 2.0
This term is also referred to as the elasticity of demand ie how much demand changes with respect to price change. It is negative here because as you increase the price, the demand decreases
Now that we have value for m all we have to do is plug it into one of the equations (1) or (2) and solve for b
Using equation (2),
20(- 2) + b = 14
==> - 40 + b = 14
==> 0 + b = 14 + 54(Add 48 on both sides)
==> b = 54
So the price-demand equation is
[tex]\boxed{\sf{p=-2x + 54}}[/tex]
Show that
(2 x 10^2) x (3 x 10^5) = 3.5 x 10^7 + 2.5 x 10^7
We have proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷ .
In the given question
we have to prove that
(2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷
For proving we will solve the LHS and RHS separately and then equate them .
First Solving LHS
we have
=(2*10²)*(3*10⁵)
=(2*3)*(10²*10⁵)
=6*10²⁺⁵ ...( because aⁿ.aˣ = aⁿ⁺ˣ )
=6*10⁷ ...(i)
Now solving RHS
we have
=3.5*10⁷+2.5*10⁷
taking 10⁷ common , we get
=(3.5+2.5)*10⁷
Adding the terms in the bracket we get
=6*10⁷ ...(ii)
As we can see that from equation (i) and (ii) we have LHS=RHS
Hence proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷
Therefore , Proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷ .

Savannah is going to invest $220 and leave it in an account for 12 years. Assuming
the interest is compounded continuously, what interest rate, to the nearest tenth of a
percent, would be required in order for Savannah to end up
with $430
Answer:
5.7%
Step-by-step explanation:
The formla for calculating compound interest is expressed as;
A = P(1+r)^t
A is the amount = $430
P is the principal = $220
r is the rate
t is the time = 12 years
Substitute and get r;
430 = 220(1+r)^12
430/220 = (1+r)^12
1.955 = (1+r)^12
1.057 = 1+r
r = 1-1.057
r = 0.057
r = 5.7%
The interest rate is 5.7%

A family used a professional decorator to help furnish their new home. The decorator selected $1,580 worth of furnishings. In addition to paying for the purchases, the family paid 4.5% tax on the purchases. The decorator's fee was 12% of the purchases, not including the tax. Write an equation in the form of y=kx to represent the decorator's fee. Then use the equation to calculate the amount of that fee. Round to the nearest hundredths place if necessary.
Answer:
Step-by-step explanation:
Worth of furnishings = $1580
Tax rate = 4.5%
Tax = 4.5% × $1580 = 0.045 × $1580 = $71.10
Amount paid = $1580 + $71.10 = $1651.10
Since the decorator's fee was 12% of the purchases. This will then be calculated as:
y = kx
where,
y = decorators fee
k = percentage of decorators fee on purchases
x = amount paid
y = 12% × $1651.10
= 0.12 × $1651.10
= $198.132

In parallelogram HIJK, the measure of angle H is 45 degrees. 1.Find the measure of J and explain how you know
Answer:
45°
Step-by-step explanation:
A parallelogram is a polygon with 4 sides and 4 angles (that is a quadrilateral).
For a parallelogram ABCD, Opposite sides and opposite angles are equal (i.e. BC = AD and ∠A = ∠C).
Consecutive angles are supplementary that is ∠A + ∠B = 180°.
The diagonals of a parallelogram bisect each other also separating the parallelogram into two congruent triangles.
In parallelogram HIJK, ∠H and ∠J are opposite angles. hence:
∠H = ∠J (opposite angles of a parallelogram are equal)
∠J = 45°
