recall that the reference angle, is the angle made by the terminal point with the x-axis.
Check the picture below.
Answer:
It is more efficient to use order of operations because with the distributive property, you would have to multiply four times and add once (5 things to do), whereas with order of operations, you have to add twice and multiply twice (4 things to do).
Step-by-step explanation:
Answer:
Answer: The estimated equation is shown in the scattered plot diagram attached to the answer supplied
Step-by-step explanation:
(a) Attached scattered plot diagram
(b) Estimated regression equation:
Rating = 3.204 + 0.076 EXPER
b1= 3.204,
b2= 0.076
Se(b1)= 0.709
Se(b2) = 0.044
n=2
The coefficient of EXPER =0.076. This implies that the quality rating will increase by 0.076.
Answer:
Step-by-step explanation:
<u>Given the sequence</u>
<u>To find </u>
- Sum of terms from i=5 to i=15
<h3>Solution</h3>
We see the sequence is AP
<u>The required sum is</u>
<u>Using sum of AP formula</u>
<u>Finding the required terms</u>
- i₁ = - 4- 6 = -10
- i₄ = -4 -6*4 = - 28
- i₁₅ = -4 -6*15 = -94
<u>Getting the sum</u>
- S₄ = 1/2*4*(-10 - 28) = -76
- S₁₅ = 1/2*15*(-10 - 94) = -780
- S₅₋₁₅ = S₁₅ - S₄ = -780 - (-76) = - 704
Um, I think it's:
(x) + (x+6) = 42
