Answer:
π4;3π4
Step-by-step explanation: Trig table gives:
sinx=√22 --> arc x=π4
Unit circle gives another arc x that has the same sin value:
x=π−π4=3π4

Answer:
The area of the large rectangle can be represented in two ways. Either the sum of each of the areas of the individual smaller rectangles, which is what the first equation represents, as its the base multiplied by the height (a) of each rectangle.
The second equation is a simplified version of the first one, and can be explained in three ways:
Each of the terms in the earlier equation had a common factor of a, which could be taken outside the parentheses.
or
Since the height is the same for each of the smaller rectangles, you can just multiply the height times the sum of the three smaller rectangle's widths
or
The width of the large rectangle is just the sum of each of the smaller widths, so the sum of those multiplied by a will give the area of the large rectangle.
Hope this helps!
Answer:
The mean is 11.5
The median is 6
Step-by-step explanation:
First put all the terms in order from smallest to largest
2, 3, 5, 6, 6, 7, 8, 55
The mean is the average. To figure the mean add all the terms together and divide by the number of terms.
There are 8 terms
2+3+5+6+6+7+8+55=92
92/8=11.5
The median is the middle of all the terms. To figure the median find the middle two terms and find their average.
Hint: If the middle two terms are the same number, the median is that number.
The middle two terms are 6 and 6 so the median is 6
Answer:
B. (-2, 0) and (1, 0)
Step-by-step explanation:
The equation can be factored as ...
y = 2(x^2 +x -2) = 2(x +2)(x -1)
The x-intercepts are the values of x where y=0, so will be the values of x that make one or the other of the binomial factors zero:
x = -2
x = 1
Then the intercept points are (-2, 0) and (1, 0). . . . . . . . . matches choice B
