Answer:

162 degrees

Step-by-step explanation:

Angles P and F are supplementary, so ...

3x^2 +12x = 180

x^2 +4x = 60

x^2 +4x -60 = 0

(x +10)(x -6) = 0

The useful value of x that makes this true is x=6.

The measure of angle Q is 3x, so is 3·6 = 18 degrees. The measure of angle S is the supplement to that:

∠S = 180° -18° = 162°

Which function has a range of all real numbers greater than or equal to -4?

max2010maxim [7]

Answer:

C. $f(x)=(x+1)^2-4$

Step-by-step explanation:

A. the graph is a straight line with slope 1. It goes up/down infinitely far so the range is all real numbers. Not A!

B. The graph is a straight line with slope -4, so, like the function in A, the range is all real numbers. Not B!

D. The graph is an absolute value function y = |x|, reflected over the x-axis, shifted right 3 units, then shifted down 4 units. So the graph starts witha "vee" shape opening up, becomes a vee opening down, then ultimately gets shifted down 4 units. The range is all real numbers less than or equal to -4.

See the attached graphs. image2 is the function in answer choice D.

Find the area the sector.arc circle 10A. 16π mi²B. 34π/3 mi²C. 5π/3 mi²D. 9π mi²

erastova [34]

Answer: $\frac{14\pi}{3}mi^2$ Explanation:

The area of a sector is given as:

$\begin{gathered} Area\text{ = }\frac{\theta}{360}\times\pi r^2 \\ \\ \end{gathered}$

The sector angle, θ = 360° - 255°

θ = 105°

The radius, r = 4 mi

Substitute these values into the equation to solve for the area

$\begin{gathered} Area=\frac{105}{360}\times\pi\times4^2 \\ \\ Area=\frac{105}{360}\times16\pi \\ \\ Area=\frac{7}{24}\times16\pi \\ \\ Area=\frac{7}{3}\times2\pi \\ \\ Area=\frac{14\pi}{3}mi^2 \\ \end{gathered}$

The relationship is not proportional if it does not include (0, 0). Here, the point (1, 0) is your clue that there is no proportional relationship involved.

_____

The relationship is linear. A linear relationship is only a proportional relationship if the line goes through the point (0, 0).
