Answer:
The order of rotational symmetry of the wheel is;
C) 12
Step-by-step explanation:
The order of rotational symmetry of a shape is given by the sum of the times the shape can by rotated round 360° and still appears to be exactly the same as it was before being rotated
The given wheel has 6 pairs of similar in-line spokes such that there are a total of 12 spokes
The wheel looks the same each time the next spoke moves to the position of the previous spoke
Therefore, the number of times the wheel looks exactly the same while turning 360° is 12 times
Therefore, the order of rotational symmetry of the wheel = 12.

Rewrite in scientific notation 0.000357
Answers
Answer:
3.57 x 10^-4
Step-by-step explanation:
see how many places you have to move the decimal to create a number that is greater than or equal to one, in this case that number would be 3.57
we had to move the decimal four places to get it there
when moving to the left the exponent is negative
when moving to the right the exponent is positive
Answer:
3.57 × 10-4
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form
m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.000357 into scientific notation, follow these steps:
Move the decimal 4 times to right in the number so that the resulting number, m = 3.57, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -4
Write in the scientific notation form m × 10n
= 3.57 × 10-4
Therefore,
3.57 × 10-4 is the scientific notation form of 0.000357 number and 3.57e-4 is the scientific e-notation form for All numbers in scientific notation or standard form are written in the form

The expression 16t^2 represents the distance in feet the object falls after t seconds. The object is dropped from a height of 906 feet. What is the height in feet of the object 2 seconds after it is dropped?
Answers
Answer:
824 feet
Step-by-step explanation:
Given
[tex]h(t) = 16t^2[/tex]
[tex]H = 906[/tex] -- Initial Height
Required
Determine its height after 2 seconds
First, we calculate the distance covered in 2 seconds
[tex]h(t) = 16t^2[/tex]
[tex]h(2) = 16*2^2[/tex]
[tex]h(2) = 16*4[/tex]
[tex]h(2) = 64[/tex]
This means that the object moved a distance of 64feet
So, the object height is calculate by subtracting the distance covered from the object's initial height:
i.e.
[tex]Height = H - h(2)[/tex]
[tex]Height = 906- 64[/tex]
[tex]Height = 824[/tex]
Knowing the expression for the distance the object falls, the height of the object 2 seconds after it is dropped is 842 feet.
In first place, you know that the expression 16×t² represents the distance in feet the object falls after t seconds.
You want to know the height in feet of the object 2 seconds after it is dropped. For that, you must first calculate the distance traveled in 2 seconds. So you replace the time t by 2 seconds in the previous expression:
16×2²= 16×4= 64 feet
This means that the object moved a distance of 64 feet.
Knowing that the object is dropped from a height of 906 feet, the object height is calculate by subtracting the distance covered from the object's initial height:
Height= Initial Height - Distane covered
Height= 906 feet - 64 feet
Height= 842 feet
Finally, the height of the object 2 seconds after it is dropped is 842 feet.

Answers
Answer:

Step-by-step explanation:
take 35*2 to get the total (70)
take 8% (for the sales tax) or 0.08 times $70 to get 5.6

Consider the system of linear equations 2x + 3y = 8 and 3x + y = –2. Which statement is correct?
The point (1, 2) is not a solution to the system of equations because it satisfies neither equation.
The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
The point (1, 2) is a solution to the system of equations because it satisfies the equation 2x + 3y = 8.
The point (1, 2) is a solution to the system of equations because it satisfies both equations.
Answers
Answer:
Answer: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
Step-by-step explanation:
System of Equations
Consider the following system of equations
2x + 3y = 8 [1]
3x + y = -2 [2]
And the point (1,2). Substituting in both equations:
For equation [1]:
2*1 + 3*2 = 8
2 + 6 = 8
8 = 8
Since the equation is true, point (1,2) satisfies the equation 2x + 3y = 8
Now for equation [2]:
3*1 + 2 = -2
3 + 2 = -2
5 = -2
Since this equation is false, point (1,2) does not satisfy the equation 3x + y = -2
Answer: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
Answer:
B: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
