Answer:
D
Step-by-step explanation:
Try to remember this formula.
Where a is the vertical multiplier, b is the horizontal multiplier, c is the x coordinate of the vertex, and d is the y coordinate of the vertex.
Since the vertex on the graph is (2,3), c and d have to be 2 and 3.
Also, there are no vertical/horizontal stretches so the a and b values stay at 1.
The final equation would come out to
Sin-495 = 0.98
cos-495 = 0.19
tan-495 = 4.95
sin<span>-20π/3</span> = 0
cos<span>-20π/3</span> = 0.3
tan<span>-20<span>π/3</span></span> = 0
Answer:
The mean absolute deviation is: 7.44
Step-by-step explanation:
Given
Required
The mean absolute deviation
First, calculate the mean
The mean absolute deviation (M) is:
So, we have:
Remove absolute brackets
The second step would be to find the reciprocal of 5/3. When you divide 4/7 by 5/3, you end up with a double-decker fraction (as my teacher called it) which makes things much more difficult. However, to make things easier, find the reciprocal of 5/3 (which is 3/5) so that you can straight up multiply it across. With this done, you can solve for g:
g=4/7*3/5
g=12/35
First use slope formula, y2 - y1 / x2 - x1 on the points, 4-2 / 4-3, the slope is 2. then plug this into the equation y = mx + b where m is the slope. use one of the points to solve for b, i will use (3, 2). 2 = 2(3) + b. Solving for b, you would get b = -4. so now you have everything you need, the equation would be y = 2x - 4
