Answer:28.071
Step-by-step explanation:
Given
vector component is (15,8)
i.e. its x component is 15 from origin and y component is 8 m
So angle made by vector with x axis is
Express 9 ten thousandths in Scientific notation
2 answers:
Answer:
9 ten thousandths is equivalent to 0.0009 or
Explanation:
Scientific notation states that it is used to represent very large and very small numbers and a number is written as a number between 1 and 10 multiplied by a power of 10.
Given: 9 ten thousandths
Then,
9 ten thousandths = = 0.0009
Negative exponent states that the decimal point is to be shifted to the left by that number of places to arrive at the number in long form.
0.0009 =
Therefore, 9 ten thousandths in Scientific notation is equivalent to 0.0009 or

Answer:
Option (3). 72°
Step-by-step explanation:
Angle of rotational symmetry = Central angle of a polygon
That means when we rotate the regular polygon by a central angle, polygon overlaps itself.
Central angle of a polygon with n sides =
Where n = number of sides of the polygon
Therefore, central angle of a polygon with 15 sides =
= 24°
Central angle tells us that after every 24° of rotation, polygon overlaps itself.
Angle of rotational symmetry may be 48°, 72°, 96°.....
Therefore, Option (3) is the possible angle of rotational symmetry.
Answer:
The product is
Step-by-step explanation:
To do this we must understand how the basic operations apply to powers. If the power has the same base and we multiply them, the base remains the same while we sum the powers, if we divide them the base remains the same and we subtract the powers, if we try to make a power of a power the two powers multiply. Applying this rule we have:
