Find the 50th term sequence 5 , -2 , -9 , -16

Anni [7]

5 - 7 = - 2 ;
- 2 - 7 = - 9 ;
-9 - 7 = -16 ;
"common difference" d is - 7 ;
The n-th term of an arithmetic sequence is of the form <span>an = a1 + (n – 1)d ;
</span>a50 = 5 + 49 × ( - 7 ) = 5 - 343 = - 338;

What is the coefficient of determination for two variables that have perfect positive linear correlation or perfect negative lin

Aloiza [94]

Answer:

r^2 = 1

Step-by-step explanation:

The computation of the coefficient of determination for the two variables is shown below:

here the perfect positive linear correlation is r = 1

And, the negative linear correlation is r = -1

Based on this, the coefficient of determination is equivalent to the linear correlation coefficient square

$r^2 = (\pm)^2 \\\\ = 1$

This above describes that variation that lies between the variables as explained by the linear regression line

If tan e = 1.3, what is the value of cot (90° - 9)?

ella [17]

Answer:

Step-by-step explanation:

We are given that:

$\tan(\theta)=1.3$

And we want to find:

$\cot(90^\circ -\theta)$

Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:

$\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)$

Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.

Our answer is A.
