Given cosθ = .876 and tanθ = -4.731 determine sinθ
Answers
Answer:
[tex]sin\theta[/tex]= -4.144356
Step-by-step explanation:
[tex]tan\theta=\frac{sin\theta}{cos\theta}[/tex]
Therefore:
[tex]sin\theta = tan\theta.cos\theta[/tex]
[tex]sin\theta[/tex] = -4.731 × 0.876
[tex]sin\theta[/tex] = -4.144356

to find the other missing measure (slanted side) use pythagorean theorem
c^2 = a^2 + b^2
c^2 = 6^2 + 8^2
c^2 = 36 + 64
c^2 = 100
c = 10
then add all the measurements since it’s perimeter
10 + 6 + 8 = 24
Answer:
P=22

b=8
h=6
the slanted side=8
8+8+6=22

Answer:
X in.
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
We use the Pythagorean theorem
a^2 + b^2 = c^2, here, x is a, x + 2 = b, and 10 is c
x = 6:
6^2 + (6 + 2)^2 = 10^2
36 + 8^2 = 100
26 + 64 = 100
100 = 100
x = 6

Jeff drew a line through (0, 0) and (7, 7) and said it was the line of best fit for the data.
Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?
Answers
Answer:
The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed
Step-by-step explanation:
Answer:
The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.
