Step-by-step explanation:
picture below ;)
A line became by joining two coordinates, the midpoint of the given line segment is (-3.5,1.5).
What is a line segment?
A line segment is become by joining two points which has specific coordinates.
To find the midpoint coordinate between any two points then we have to add the x's coordinates and divide by two and similarly y's coordinates and divide by two.
For example, if you have two points as (a,b) and (c,d) then the coordinate of the midpoint joining this line will be ( [tex]\frac{a+c}{2}[/tex], [tex]\frac{b+d}{2}[/tex] ).
Since the points are (-1,5) (-6,-2) so the midpoint joining this line segment will be
( [tex]\frac{-6-1}{2}[/tex], [tex]\frac{5-2}{2}[/tex] ) so (-3.5,1.5) will be the midpoint of the line segment.

A park started with 12 oak trees, and the number of oak trees increased at a rate of 25% each year. Write the function that models the situation, substituting numerical values for A and r into the expression.
f(x)=A(1+r)X
Answer:
[tex]f(x) = 12(1.25)^{x}[/tex]
Step-by-step explanation:
The number of oak trees after x years is given by a function in the following format:
[tex]f(x) = A(1+r)^{x}[/tex]
In which A is the initial number of oak trees, and r is the growth rate, as a decimal.
A park started with 12 oak trees
This means that [tex]A = 12[/tex]
The number of oak trees increased at a rate of 25% each year.
This means that [tex]r = 0.25[/tex]
So
[tex]f(x) = A(1+r)^{x}[/tex]
[tex]f(x) = 12(1+0.25)^{x}[/tex]
[tex]f(x) = 12(1.25)^{x}[/tex]

The scale factor of the two shapes is 0.5 (or 1/2). True or false? B 32.4 km W 36 km 18 km True False
Answer: True
Step-by-step explanation:
The scale factor between shapes is the number that when multiplied by the dimensions of the original shape will give the dimensions of the transformed shape.
Likewise when the dimensions of the transformed shape is divided by this number, it will yield the dimensions of the original shape.
The original shape has a length of 36km.
= 36 * 0.5
= 18 km
This proves that 0.5 is the scale factor because when the length of the original shape was multiplied by it, the result was the length of the transformed shape.

Year = x
Weight (kg) = y
Rate of change between 2010 and 2011 = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Where,
[tex] (2010, 35) = (x_1, y_1) [/tex]
[tex] (2011, 30) = (x_2, y_2) [/tex]
Plug in the values
[tex] = \frac{30 - 35}{2011 - 2010} [/tex]
[tex] = \frac{-5}{1} = -5 [/tex]
Rate of change = -5kg per year
This means that there was a decrease in the weight of the winning dog form 2010 to 2011 by 5 kilograms

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a small petting zoo has Llamas and Kangaroos. There are 120 legs and 47 heads on this farm.
The equations will be formed as,
4L + 2K = 120
L + K = 47
Solve the above equations by elimination method,
4L + 2K = 120
-4L -4k = -188
____________
0 - 2K = -68
K = 34
The number of the Lamas will be,
L + K = 47
L = 47 - K
L = 47 - 34
