The midpoint of the line segments with
1) (-4,-2), (3, 3) is ( -1/2 , 1/2).
2) (−1, −6), (−6, 5) is ( -7/2 , -1/2 ).
3) (2, 4), (1, −3) is ( 3/2 , -1/2).
In geometry, the midpoint is defined as the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment. To determine the midpoint, just add the two X-values, then divide by 2 and add the two Y-values, then divide by 2. Mathematically, let (xm , ym) be coordinates of mid point of line segment ents with end points ( x₁, y₁) , (x₂, y₂). Then, xₘ =( x₁ + x₂)/2 and yₘ = ( y₁ + y₂)/2
We have , the line segments with coordinates
1) (-4,-2), (3, 3)
Midpoint = ( (-4 + 3)/2 , (-2 + 3/2) )
= ( -1/2 , 1/2)
2) (−1, −6), (−6, 5)
Midpoint = ( ( -6 +(-1))/2 , ( -6 + 5)/2)
= ( -7/2 , -1/2 )
3) (2, 4), (1, −3)
Midpoint = ((2 + 1)/2 , (4+(-3))/2)
= ( 3/2 , -1/2)

Eiko is wearing a magic ring that increases the power of her healing spell by 30 % 30%30, percent. Without the ring, her healing spell restores � HH health points. Which of the following expressions could represent how many health points the spell restores when Eiko is wearing the magic ring?
The expression 1.3H represents the relationship between the number of health points restored by Eiko's healing spell with and without the magic ring.
H represents the number of health points restored by the spell without the ring. The expression 0.3H represents the additional 30% increase in the power of the spell due to the magic ring, as the ring increases the spell's power by 30%.
Adding the two, H + 0.3H, gives us the total number of health points restored by the spell with the magic ring, which is equal to 1.3 times the number of health points restored by the spell without the ring.
So, when Eiko is wearing the magic ring, her healing spell restores 1.3 times as many health points as without the ring, represented by the expression 1.3H.

help meeeeee pls!!!!
Step-by-step explanation:
domain : the interval or set of all valid x-values.
range : the interval or set of all valid y-values (function result values).
A is correct
theoretically all real numbers are valid as x. but for this application of the function only non-negative integer values make sense (e.g. half a cycle does not make any sense).
C is correct
via A we are allowing all real numbers to be valid input values, so, we have to allow also all real numbers to be valid output (function result) values.
D is correct
the y-intercept means the y-value, when the function curve intersects the y-axis.
this is only possible, when x = 0.
5⁰ = 1
as any x⁰ = 1
F is correct
the bigger x, the bigger 5^x.
and the smaller x, the closer y, the function result, gets to 0. particularly, when we allow negative input values (as we said in A).
What is the angle between lines 2x 3y =- Z?.
The angle between lines 2x 3y =- Z is 90°
We will simplify the given equation of lines in the standard form of x/a=y/b=z/c
where a, b and c are the direction ratios of the line.
We will calculate the angle between these lines using the formula:
[tex]cos\alpha =\frac{a_{1}a_2 +b_1b_2+c_1c_2}{\sqrt{a_1^2+b_1^2+c_1^2}\sqrt{a_2^2+b_2^2+c_2^2} }[/tex]
we are given two lines as 2x = 3y = – z and 6x = -y = -4z
We can write them in standard form xa=yb=zc
as:
For 2x = 3y = – z ⇒x/1/2=y/1/3=z/−1/4
Comparing this equation with the standard equation, we get the direction ratios of this line:
a₁= 1/2
b₁=1/3
c₁ = -1
For 6x = -y = -4z ⇒x/1/6=y−1=z/−1/4
Comparing this equation with the standard equation, we get the direction ratios of this line:
a₂= 1/6, b₂= -1, c₂= −1/4
Now, putting these values of a₁, a₂, b₁, b₂, c₁, and c₂
in the equation of cosα, we get
[tex]cos\alpha =\frac{a_{1}a_2 +b_1b_2+c_1c_2}{\sqrt{a_1^2+b_1^2+c_1^2}\sqrt{a_2^2+b_2^2+c_2^2} }[/tex]
[tex]cos\alpha =\frac{\frac{1}{2} *\frac{1}{6} +\frac{1}{3} *(-1)+(-1)\frac{(-1)}{4} }{\sqrt{(\frac{1}{2})^2 +(\frac{1}{3})^2 +(-1)^2}\sqrt{(\frac{1}{6} )^2+(-1)^2+(\frac{-1}{4})^2 } }[/tex]
[tex]cos\alpha =\frac{\frac{1}{12} -\frac{1}{3} +\frac{1}{4} }{{\sqrt{(\frac{1}{2})^2 +(\frac{1}{3})^2 +(-1)^2}\sqrt{(\frac{1}{6} )^2+(-1)^2+(\frac{-1}{4})^2 } } }[/tex]
[tex]cos\alpha =\frac{\frac{1}{12} -\frac{1}{12} }{{\sqrt{(\frac{1}{2})^2 +(\frac{1}{3})^2 +(-1)^2}\sqrt{(\frac{1}{6} )^2+(-1)^2+(\frac{-1}{4})^2 } } }[/tex]
cosα=0°
cos⁻¹(cosα)=cos⁻¹(0)

Four friend went to the movie. Each ticket cot $8 and each peron brought popcorn and a oda for $5 dollar. How much did they pend in all? Show two way to write the expreion or equation and olve
They spend $52 in total for the movie ticket and popcorn.
The substitution method is a simple way to solve a system of linear equations algebraically and find the solutions of the variables.
Given that,
Tickets (t) = $8
Popcorn & Soda (s)= $5
Friends = 4
Since all friends bought the same thing the equation will be set as
4(t +s) = m OR 4t +4s = m
Using substitution, you plug each variable
t = 8 and s = 5
4((8) + (5)) = m
4(8+5) = m => 4(13) =m => 52=m

The amount on line 10 (total payments and credits) must be equal to the amount on line 11 (amount you owe) which is C: $4184.
How to calculate difference?
The difference is a mathematical operation used to find the amount by which one number is greater or smaller than another number. It is calculated by subtracting the smaller number from the larger number. The difference can be represented by the symbol "-" or the word "minus"
The dollar amount that could be on line 10 if $4184 is on line 11 and the taxpayer will neither receive a refund nor owe the IRS is $4184.
Line 10 on the 1040EZ form is for the "Total payments and credits" which is the sum of all payments made throughout the year, including any tax payments, estimated tax payments, and any credits the taxpayer is entitled to.
Line 11 is for the "Amount you owe" which is the difference between the total tax liability (calculated on the form) and the total payments and credits.
If the taxpayer will neither receive a refund nor owe the IRS, it means that the total payments and credits are equal to the total tax liability.

Question 1: Determine the value of the dependent variable given a value of the independent
Question 2: Determine the value of the independent variable given a value of the dependent
Show how you would solve both problems using only algebra. Show all of the steps.
Question 1: The value of the dependent variable given a value of the independent is 11.54 (thousands of people)
Question 2: The value of the independent variable given a value of the dependent is 1998 (5 years after 2000)
How do we get the values?Real-life application problem: The population of a city is growing at a rate modeled by the equation y = log(5x + 10) + 8, where y is the population in thousands and x is the number of years since the year 2000.
To determine the key properties of the function and sketch its graph:
The function is a combination of a logarithmic and an exponential function.
The domain of the function is all real numbers (since the logarithm function is defined for all positive numbers)
The range of the function is all real numbers greater than or equal to 8 (since the minimum value of the function is 8)
The graph of the function will be a smooth, continuous curve that starts at the point (0,8) and increases without bound as x increases.
Question 1: Determine the value of the population (y) given a value of x = 5 (number of years since 2000)
Solution:
y = log(5x + 10) + 8
y = log(5(5) + 10) + 8
y = log(25 + 10) + 8
y = log(35) + 8
y = 3.54 + 8
y = 11.54 (thousands of people)
Question 2: Determine the value of x (number of years since 2000) given a population of y = 12 (thousands of people)
Solution:
y = log(5x + 10) + 8
12 = log(5x + 10) + 8
4 = log(5x + 10)
5x + 10 = 10^4
5x = 9990
x = 1998 (5 years after 2000)
Note that this is not a realistic scenario, as the population of a city cannot be negative except in the case of extinction.

(B) 0.00334 in
(C) 0.00668 in
(D) 0.0134 in
(E) 0.0267 in
The water level will increase by 0.00167 inches, so the correct option is A.
By how much did the water level in the pool increase?
We know that Lisa spilled a volume of 1 quart of water on its pool, and the dimensions of the pool are:
12ft = 12*(12 inches) = 144 inches
20ft = 20*(12 inches) = 240 inches.
And we know that:
1 quart = 57.75 in³
Then if the level change is H, then then we can write the equation for the volumes:
1 quart = volume of increase in the pool
1 quart = (144 in)*(240 in)*H
57.75 in³ = (144 in)*(240 in)*H
H = (57.75 in³)/( (144 in)*(240 in))
H = 0.00167 in

Eva is deciding between two landscaping companies for her place of business.
Company A charges $35 per hour and a $300 equipment fee. Company B charges $45
per hour and a $100 equipment fee. Let A represent the amount Company A would
charge for t hours of landscaping, and let B represent the amount Company B would
charge for t hours of landscaping. Write an equation for each situation, in terms of t,
and determine the number hours, t, that would make the cost of each company the same.
For seven hours of landscaping, Company B would be less expensive than Company A.
What is an equation?An equation is defined as any pair of expressions that both contain the equal sign.
Because of this, Company charges $35 per hour and a $250 equipment fee, compared to Company B's $25 per hour and $300 equipment fee.
For t hours of landscaping, Company A will bill the following:
A = 35t + 250 (1) (1)
In a similar vein, Company B bills the following sum for t hours of landscaping:
B = 25t + 300 (2) (2)
Solve equation (1) now with t = 7:
A = 35 (7) + 250
A = 245 + 250
A = 495
So, for 7 hours of landscaping, business A would bill $495.
Similarly, when equation (2) is resolved for t = 7,
B = 25(7) + 300
B = 175 + 30
B = 475
So, for 7 hours of gardening, business B would bill $475.
Therefore, for seven hours of landscaping, Company B would be less expensive than Company A.

Tell whether b=11 is a solution of -3=8-b .
Answer:
Yes. Since 8 - 11 is -3, -3= -3
Step-by-step explanation:
-3=8-b
-3=8-11
-3=-3
Answer:
Look Below ↓↓↓
Step-by-step explanation:
Let's solve it and see if it is:-
[tex]\bf -3=8-b[/tex]
Simplify both sides of the equation:-
[tex]\bf -3=8-b[/tex]
[tex]\bf -3=8+-b[/tex]
[tex]\bf -3=-b+8[/tex]
Flip the equation:-
[tex]\bf -b+8=-3[/tex]
Subtract 8 from both sides:-
[tex]\bf -b+8-8=-3-8[/tex]
[tex]\bf -b=-11[/tex]
Divide both sides by -1:-
[tex]\bf \cfrac{-b}{-1}=\cfrac{-11}{-1}[/tex]
[tex]\bf b=11[/tex]
Therefore, yes b = 11!!

The dimensions of a cylinder are shown in the diagram. Which measurement is closest to the lateral surface area in square centimeters of the cylinder
The lateral surface area of a cylinder is 1110.8 cm².
Derive the formula for the volume of cylinder.Consider a very thin cross section of a cylinder whose thickness is [dh] {differential or very small value}. The volume of this cross section would be -
dV = πr² dh
For complete cylinder -
∫dV = πr² ∫dh
[V - 0] = πr² [h - 0]
V = πr²h
Given are the dimensions of a cylinder are shown in the diagram.
We can write the lateral surface area as -
LSA = 2πrh
LSA = 2 x 3.14 x 8.8 x 20.1
LSA = 1110.8 square centimeters.
Therefore, the lateral surface area of a cylinder is 1110.8 cm².
