Answer:
A theodolite
Step-by-step explanation:
theodolite is a precision instrument that is used to measure the angle in the horizontal and vertical planes and it is the most commonly used in surveying.
A modern developed theodolite consists of a movable telescope that is mounted within two perpendicular axes called the horizontal axis and the vertical axis. Pointing the telescope on a target object will enable measurement of angle with great precision.
<span>Residual value is the difference between the observed value of the dependent variable (y) and the predicted value (ŷ) in a data set.
i.e. Residual value = given value - predicted value
From the table, the residual value corresponding to a has 4.1 as the given value and 4.5 as the predicted value.
Therefore, a = 4.1 - 4.5 = -0.4
Similarly, </span><span>the residual value corresponding to b has 7.2 as the given value and 7.05 as the predicted value.
Therefore, b = 7.2 - 7.05 = 0.15
</span>
Therefore, a = -0.4 and b = 0.15
D.) 52%, this is because there are 11 odd numbers for 1 to 21, so the fraction is 11/21, which is approximately 52%
Multiplying a vector 
by a constant 
gives you a new vector whose components are the same as , but scaled by :
So we have
Vector addition is just a matter of adding the corresponding components together:
Then
denotes the norm/magnitude of the vector :
We have
