Y = cos(x) sqrt(3)/2 = cos(30º) dy = -sin(x)*dx dy = -sin(30º)*(pi/180) = (1/2)*(pi/180) y + dy = cos(x) - sin(x)dx y + dy = sqrt(3)/2 - (1/2)*(pi/180) = 0.8573

What is the range of the function graphed on the grid? { x │ x = -2, 2, 4} {y│-3 ≤ y ≤ 4} {y│ y = -3, 0, 4} { x │-2 ≤ x ≤ 4}

Neporo4naja [7]

Answer:

The image is sideways.

But if your graph is like on the image, then the answer is: {y│-3 ≤ y ≤ 4}

Range is the set of y values

Least function value is -3 and greatest is 4

Here are 10 test scores: 30, 74, 76, 77, 78, 79, 80, 80, 82, 84. The mean of these scores is 74.

creativ13 [48]

We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).

79-74 = 5. So the mean has increased by 5 points. (C)
