v ≈ - 5.29, v ≈ 5.29

Step-by-step explanation:

Given

3v² - 84 = 0 ( add 84 to both sides )

3v² = 84 ( divide both sides by 3 )

v² = 28 ( take the square root of both sides )

v = ±

Thus

v = - ≈ - 5.29

v = ≈ 5.29

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
