1. Identify the 1st 10 perfect squares?
The 1st 10 perfect squares are 1,4,9,16,25,36,49,64,81 and 100.
[tex]1^{2} =1\\2^{2} =4\\3^{2} =9\\4^{2} =16\\5^{2} =25\\6^{2} =36\\7^{2} =49\\8^{2} =64\\9^{2} =81\\10^{2} =100\\[/tex]
2. What does it mean for a number to a perfect square? provide an example.
By squaring a whole number or an integer, one can create perfect squares. Let's examine an illustration to get the idea behind perfect squares. We can use a set of four and a second set of six marbles for this. Let's set the marbles in order.
See the figure(1).
With four marbles, we can create a square with two rows and two marbles in each row. We can create a rectangle with 6 marbles that has 2 rows with 3 marbles in each row. It signifies that 4 = 2[tex]\times[/tex]2 and 6 = 3[tex]\times[/tex]2 mathematically. Let's concentrate just on the square-shaped numerals. Here, 4 = 2 × 2 = [tex]2^{2}[/tex].
Square A is smaller then Square B. Square B is smaller then Square C.
The 3 Square side length are3,4.2 and[tex]5\frac{1}{2}[/tex].
complete the equation each of the square shown.
3. Square A=Area=[tex]3^{2}[/tex]=9
4. Square B= Area=[tex]4.2^{2}[/tex]=17.64
5. Square C=Area= [tex]\frac{5}{2} =\frac{25}{4}[/tex]
Find the length of the side of the square for each area is given
6.81 square inches
Area=81=[tex]s^{2}[/tex]
s=9
7. [tex]\frac{4}{25} cm[/tex]
area=[tex]\frac{4}{25} cm[/tex]=[tex]s^{2}[/tex]
s=[tex]\frac{2}{5}[/tex]
8.0.49 Square unit
area=0.49=[tex]s^{2}[/tex]
s=0.7
The graph represent the equation [tex]y=x^{2}[/tex].
9.complete the table of values to find corresponding y-values.
if x =-1.4
Substituting in the equation [tex]y=x^{2}[/tex]
Then y=[tex]-1.4^{2}[/tex]
y=1.96.
Therefore, (x,y)=(-1.4,1.96)
if x =-1
Substituting in the equation [tex]y=x^{2}[/tex]
Then y=[tex]-1^{2}[/tex]
y=1.
Therefore, (x,y)=(-1,1)
if x =0
Substituting in the equation [tex]y=x^{2}[/tex]
Then y=[tex]0^{2}[/tex]
y=0.
Therefore, (x,y)=(0,0)
if x =[tex]\frac{2}{5}[/tex]
Substituting in the equation [tex]y=x^{2}[/tex]
Then y=[tex](\frac{2}{5}) ^{2}[/tex]
y=[tex]\frac{4}{25}[/tex].
Therefore, (x,y)=([tex]\frac{2}{5}[/tex],[tex]\frac{4}{25}[/tex])
if x =2
Substituting in the equation [tex]y=x^{2}[/tex]
Then y=[tex]2^{2}[/tex]
y=4.
Therefore, (x,y)=(2,4)
10. why the graph of equation [tex]y=x^{2}[/tex] is above x-axis.
Because the [tex]y=x^{2}\\[/tex] the x values are always positive because x as a square. So, the equation is always on x- axis or above x-axis.

She buys the car using the credit terms. How much more than the cash price will she pay overall for the car?
Answers
465 is the cost of the cash price will she pay overall for the car.
What is cost ?
The entire cost of all fixed and variable expenses for a particular stage in the value chain is the total cost of a business function. In other words, it is the overall cost incurred during the various stages a product goes through to reach the consumer.Your cost function might resemble this, for example, if your variable costs for labor are fixed regardless of quantity while your variable costs for supplies vary depending on the amount of each item. Total costs are calculated as fixed costs plus labor costs plus (unit count * material variable costs).25 % of cash price 4500 × 25% = 1125
12 monthly 320 × 12 = 3840
All 1125 + 3840 = 4965

The Greek word "parallelogrammon," which means "bounded by parallel lines," is the source of the English word "parallelogram." Thus, a quadrilateral with parallel lines as its borders is referred to as a parallelogram. The opposing sides of this form are parallel and equal. Each of the three primary varieties of parallelograms—square, rectangle, and rhombus—has distinct characteristics.
A unique variety of quadrilateral made up of parallel lines is called a parallelogram. A parallelogram can have any angle between its neighboring sides, but it must have opposing sides that are parallel for it to be a parallelogram. If the opposing sides of a quadrilateral are parallel and congruent, it will be a parallelogram. Consequently, a quadrilateral in which both sets of opposite sides are parallel and equal is referred to as a parallelogram.

Mariam read 4 books in 5 months. What was her rate of reading, in books per month? Give your answer as a whole number or a FRACTION in simplest form.
Answers
Answer:
¼ per month or 2 books in 2½ months
Mariam read 4 books in 5 months, resulting in a rate of reading of 4/5 books per month.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.
Given that,
Mariam read 4 books
She read the books in 5 months
We need to find her rate of reading, in books per month
To find the rate of reading,
Divide the number of books read by the number of months it took to read them.
In this case, Mariam read 4 books in 5 months.
So, the rate of reading would be 4 books divided by 5 months.
Simplifying this fraction, we have 4/5,
Hence, Mariam's rate of reading is 4/5 books per month.

Using proportions, the solution for the golden section is given as follows:
|AC|/|AB| = 1.6181.
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
For this problem, the segment lengths are given as follows:
|AC| = 1.|AB| = x.|BC| = 1 - x.The following proportion is true for the segment:
|AC|/|AB| = |AB|/|BC|
Hence:
1/x = x/1 - x.
x² = 1 - x
x² + x - 1 = 0.
Which is a quadratic equation with solution x = 0.618.
Then the solution for the golden section is given as follows:
|AC|/|AB| = 1/x = 1/0.618 = 1.6181.

Answer:
(1 +√5)/2 ≈ 1.618034
Step-by-step explanation:
Given point B on segment AC, you want the "golden proportion" ratio AC/AB, such that AC/AB = AB/BC. A diagram is shown with A=0, B=x, C=1.
RedefineWe can solve for the golden proportion directly by redefining points on the line segment as ...
A = 0B = 1C = rThen we have AB = 1, AC = r, BC = r-1 and the proportion of interest is ...
AC/AB = AB/BC
r/1 = 1/(r -1)
SolutionCross-multiplying gives ...
r² -r = 1
Completing the square, we have ...
r² -r + 1/4 = 5/4
(r -1/2)² = 5/4
Taking the square root gives ...
r - 1/2 = 1/2√5
r = 1/2 + 1/2√5 = (1 +√5)/2 ≈ 1.618034
The golden ratio is (1+√5)/2 ≈ 1.618034.

A toy car was kicked toward the target. the horizontal component of velocity was 8 m/s and the vertical component was 6m/s. calculate the magnitude of the resultant velocity of the soccer ball.
Answers
The magnitude of the resultant velocity of the soccer ball is 10 m/s .
Let the horizontal component of velocity be [tex]V_{x}[/tex] and the vertical component of velocity be [tex]V_{y}[/tex].
The magnitude of the resultant velocity will be represented by V.
So, we can write
The horizontal component of velocity = [tex]V_{x}[/tex] = 8 m/s
The vertical component of velocity = [tex]V_{y}[/tex] = 6 m/s
The relation between horizontal component, vertical component and resultant velocity is,
[tex]V^{2} = V_{x} ^{2} + V_{y} ^{2}[/tex]
On substituting value of horizontal component and vertical component, we get
[tex]V^{2}[/tex] = [tex](8)^{2} + (6)^{2}[/tex]
[tex]V^{2}[/tex] = 64 + 36
[tex]V^{2}[/tex] = 100
V = [tex]\sqrt{100}[/tex]
V = 10 m/s
The magnitude of the resultant velocity of the soccer ball is 10 m/s .

The distance between the two points in the simplest radical form is √61
Distance between two pointsFrom the question, we are to determine the distance between the two marked points
The marked points are (-8, 6) and (-3, 0)
The distance, d, between two points can be calculated by using the formula,
d = √((x₂ - x₁)² + (y₂ - y₁)²)
x₁ = -8
x₂ = -3
y₁ = 6
y₂ = 0
Thus,
The distance, d, between the points is
d = √((-3 - -8)² + (0 - 6)²)
d = √((-3 + 8)² + ( -6)²)
d = √((5)² + 36)
d = √(25 + 36)
d = √61
