Answer:
B, Angle V is the smallest angle.
got it right on test
First, a line that is parallel, means a line that has the same slope as the original. To find the slope of the original equation, we have to solve for y.
-2x+3y=-6
3y=2x-6
y=2/3x-2
From this equation, we can see that the slope of the line is 2/3. For every 2 units you go up, you move three units over.
Now we need to use the point (-2,0) to find the equation of the parallel line.
y-y=m(x-x)
Plug in the point coordinates and the slope, and solve for the final equation of the line.
y-0=2/3(x+2)
y=2/3x+ 4/3
274%
= 274/100
= 2.74
The final answer is 2.74~
Answer:
The first three nonzero terms in the Maclaurin series is

Step-by-step explanation:
GIven that:

The Maclaurin series of cos x can be expressed as :


From equation(1), substituting x with (4x), Then:

The first three terms of cos (4x) is:



Multiplying equation (2) with (3); we have :




Finally , multiplying 5 with
; we have:
The first three nonzero terms in the Maclaurin series is

Answer:
Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %
Step-by-step explanation:
We are given the following in the question:
Mean storage capacity = 60 ampere-hour
95% confidence interval =

Thus, the correct answer based on the confidence interval is
Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %
Since it is a two sided test we test whether the mean storage capacity is 60 Ah or different than 60 Ah
Thus, the battery storage is different from 60 Ah because the mean storage capacity does not lie in the 95% confidence interval.
