On a snow day, Robert created two snowmen in his backyard. Snowman A was built to a height of 33 inches and Snowman B was built to a height of 45 inches. The next day, the temperature increased and both snowmen began to melt. At sunrise, Snowman A's height decrease by 6 inches per hour and Snowman B's height decreased by 9 inches per hour. Let AA represent the height of Snowman A tt hours after sunrise and let BB represent the height of Snowman B tt hours after sunrise. Graph each function and determine which Snowman is taller after 3 hours.
Answers
Step-by-step explanation:
Multiply 6 by three to see the amount of decrease in snowman A. Then, multiply 9 by three to see the amount of decrease in snowman B. Then subtract the 6 x 3 by 33. (33-(6x3) = the height of snowman A. Now, time for snowman B, subtract 45 by the
9 x3. 45- (9 x 3). Compare you answer and you'll see who is taller after the three hours.

Which describes how to find all rotation angles less that 360° that will map a regular polygon onto itself?
Answers
This question is about rotations of polygons.
To rotate a polygon onto itself, we need to know the exact rotation we have to do. This rotation depends on the type of polygons, specifically, the number of sides.
To know the exact angle rotation to map the polygon onto itself, we just have to divide 360° by the number of sides.

The measure of the hypotenuse n is 5√3
Hypotenuse
Hypotenuse refers the longest side of a right-angled triangle, the side opposite the right angle. And the length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
Given,
Here we have the triangle with some measures on it.
Here we need to find the value of n.
While we looking into the diagram, we have identified that, n is the hypotenuse of the triangle,
So, the value of n is the root of the product of the two hypotenuse segments it touches:
=> n = √(5·15)
=> n = √75
It can be simplified as,
=> n = √(3 x 25)
=> n = 5√3
Therefore, the value of n is 5√3.

The solution of the inequality:

And the graph can be seen below.
How to solve the inequality?Here we start with the inequality:
-0.8*b + 2.3 > 8.7
To solve this we need to isolate the variable b.
Let's do that in the right side:
-8.7 + 2.3 > 0.8*b
-6.4 > 0.8*b
-6.4/0.8 > b
-8 > b

There are 128 teams entered in a basketball tournament. Half of the teams are eliminated each round. How many teams are left after 4 rounds?
Answers
We have 128 teams.
In each round, half of the teams remain, so if T is the number of teams and n is the number of rounds, we have:
[tex]T(n)=0.5\cdot T(n-1)[/tex]and we start with n=0 so T(0)=128.
Then, we can use this recursive expression to find T after four rounds (n=4), but it is better if we derive an explicit formula for T in function of n (and not in function of the past terms of the sequence):
[tex]\begin{gathered} T(1)=0.5\cdot T(0) \\ T(2)=0.5\cdot T(1)=0.5\cdot0.5\cdot T(0)=0.5^2\cdot T(0) \\ T(n)=0.5^n\cdot T(0)=0.5^n\cdot128 \end{gathered}[/tex]With the last expression we can calculate T for any value of n. Then, for n=4, we have:
[tex]T(4)=0.5^4\cdot128=(\frac{1}{2})^4\cdot128=\frac{1}{2^4}\cdot128=\frac{1}{16}\cdot128=8[/tex]NOTE: in this case, its better to express the factor 0.5 as a fraction instead of a decimal.

The equation for line j can be written as y =
= -5/7x-10. Line k, which is parallel to line j,
includes the point (-9, 5). What is the equation of line k?
Answers
The equation of the line which is parallel to the other equation is;
[tex]y + \frac{5x}{7} +\frac{10}{7} =0[/tex].
What is the Relation between two Parallel Lines?
To determine whether two lines are parallel or not, apply the parallel line's formula. When we have the slope of two lines that we want to compare, the parallel line formula can be used. The separation between the parallel lines remains constant. Parallel lines are those that never cross each other. Since the two lines are equal in this situation and the angle is 180 degrees, they will never intersect.
In the given equation, we have:
The equation of the line is y = -5/7x-10.
and, Line k, which is parallel to the line of the equation :
[tex]y = \frac{-5x}{7} -10.[/tex]
[tex]y + \frac{5x}{7} +10. =0[/tex]
So, the equation of the line which is parallel to the line of the equation is:
[tex]y + \frac{5x}{7} +k. =0[/tex]
and since the two lines are parallels
So, the slope of equation 1 and the slope of equation two will be the same;
Also, It is given that the line includes the point (-9, 5).
So,
[tex]5 + \frac{5 \times -9}{7} +k. =0[/tex]
⇒[tex]k = -\frac{5 \times -9}{7} -5[/tex]
⇒[tex]k = \frac{10}{7}[/tex]
So, The equation of the line which is parallel to the other equation is;
[tex]y + \frac{5x}{7} +\frac{10}{7} =0[/tex].
Hence,
The equation of the line which is parallel to the other equation is;
[tex]y + \frac{5x}{7} +\frac{10}{7} =0[/tex]..

What is the exterior angle theorem?In Mathematics, the exterior angle theorem can be defined as a theorem which states that the measure of an exterior angle in a triangle is equal in magnitude to the sum of the measures of the two remote or opposite interior angles of that triangle.
How to determine the value of angle ZK?In order to determine the value of ∠G in triangle JKL (ΔJKL), we would have to apply exterior angle theorem. Mathematically, the exterior angle theorem can be used to model the angles in triangle JKL (ΔJKL) and this is given by:

Which is the domain and range of the parabola with the equation y = 0.5(x²-10x-5)?
Answers
The domain of the given function is the set of all real numbers that is represented as x ∈ (-∝,∝ ) and range of the function is [-15,∝).
What is domain and range of a function?The set of values that can be plugged into a function is known as its domain. The range of a function is the collection of all potential values that can result from the dependent variable, or the collection of all possible values after substituting the domain.
Domain of a polynomial function is the set of all real numbers which is given by x ∈ (-∝,∝ ).
Since the given function y = 0.5(x^2 - 10x - 5) is a polynomial function, it's domain is x ∈ (-∝,∝ ).
To obtain the range of the function, plot the graph of the parabola which is shown in the figure.
The vertex of the parabola is at (5,15). Value of y does not go below 15. Therefore the set of all possible values that the function takes is given by [-15,∝).

True or False? Every quadrilateral is a rhombus. Every parallelogram is a quadrilateral. Every square is a quadrilateral. Every rhombus with four right angles is a square. X Ś True False O True False O True False True False ?
Answers
First of all it's important to note that all parallelograms, rhombuses and squares are quadrilateral and they meet the following properties:
- Rhombus: quadrilateral whose four sides have the same length.
- Parallelogram: quadrilateral that has two pairs of parallel sides.
- Square: quadrilateral whose four sides and internal angles have the same length/measure.
With these definitions in mind we can solve the True or False table in the picture.
The first statement is false not every quadrilateral is a rhombus. For example rectangles that are not squares are not rhombuses since their four sides aren't all equal.
The second is true, as we saw before parallelograms are quadrilaterals. The same reason applies to the third statement, squares are qudrilaterals.
Now let's see the last statement. A rhombus with four right angles is a quadrilateral that has four equal sides (because it's a rhombus) and four equal angles (all measuring 90°). These are the conditions required for a quadrilateral to be considered a square so this last statement is true.

The center of dilation is outside figure A
In this question, rectangle A is dilated to rectangle B.
We know that, the center of a dilation is nothing but a fixed point about which all points are expanded or contracted.
We can observe that B = 1/2 * A
This means, the scaling factor is k = 1/2
Let's determine the center of dilation:
P'(x, y) = O(x, y) + k · [P(x, y) - O(x, y)]
Where:
O(x, y) - Center of dilation.
k - Scale factor
P(x, y) - Original point
P'(x, y) - Resulting point
(3, 1) = O(x, y) + 1/2 [(6, 2) - O(x, y)]
(3, 1) = O(x, y) - 1/2 O(x, y) + (3, 1)
1/2O(x, y) = (0, 0)
so, the center of dilation is the origin (0, 0)
