The sum of two vectors is (- 0.5, 10.1)
<u>Explanation:</u>
To add two vectors, add the corresponding components.
Let u =⟨u1,u2⟩ and v =⟨v1,v2⟩ be two vectors.
Then, the sum of u and v is the vector
u +v =⟨u1+v1, u2+v2⟩
(b)
Two vectors = ( 3, 4 )
angle 2π/3 = 120°
In x axis, the vector is = 7 cos 120°
In y axis, the vector is = 7 sin 120°
= 7 X 0.866
= 6.062
The second vectors are ( -3.5, 6.062)
Sum of two vectors = [( 3 + (-3.5) ), (4 + 6.062)]
= (- 0.5, 10.1)
Answer:
6 - 
3² - 
7 - 
= 
Step-by-step explanation:
1. 6 - 
First, apply the exponent to 2/3. Because it's to the second power, multiply 2/3 by itself.
6 - 
Now, subtract.
6 - =
------------------------------------------
2. 3² - 
First, apply the exponent.
3² = 9
9 -
Now, subtract.
9 - 
------------------------------------------
3. 7 -
First, apply the exponent.
= 
7 -
Now, subtract.
7 - 
hope this helps!
Answer:
i. The y -axis starts at zero but has different intervals.
ii. Different bar widths are used on the same graph.
iii. The y -axis doesn't start at zero.
Step-by-step explanation:
A graph is a plot showing accurate representation and presentation of correlation among variables of a given data. It is a tool that can be used to summarize all information about a given data for easy understanding and deductions.
A misleading graph is one that has an inappropriate representation of data, thus a wrong conclusion would be deduced or obtained from this type of graph. Misleading graph is majorly due to inconsistency, and errors in plot (axis or scale used).
90 - 120 is the answer because that bar is higher
