A coordinate grid is shown below. 12 11 -1 0 -1 -2 Part A: Which point represents the origin? (2 points) Part B: Starting from t

Veronika [31]

Answer:

Part A: Which point represents the origin?

The origin is the point with both zero coordinates: (0, 0)

Part B: Starting from the origin, explain how to plot the following three points accurately (1,-1) (-1.1.25) (-2,3).

Reference point is the origin for below.

(1,-1) - go right by 1 unit and down by 1 unit, plot the point
(-1.1.25)- go left by 1 unit and up by 1.25 or 1 and 1/4 units, plot the point
(-2,3) - go left by 2 units and up by 3 units and plot the point

What is the effect on the graph of the function f(x) = 2x when f(x) is replaced with f(−5x)?

Amiraneli [1.4K]

Answer:

C) horizontal compression and reflection across the y-axis

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.

Please see the attached image below, to find more information about the graph

The original equation is:

f(x) = 2x

The new equation is:

f(-5x) = 2(-5x)

f(-5x) = -10*x

The answer is

C) horizontal compression and reflection across the y-axis

Find the volume (in terms of pi) of a sphere of its surface area is 400 pi ft2

elixir [45]

$\bf \textit{surface area of a sphere}\\\\ SA=4\pi r^2\qquad \qquad \implies \stackrel{SA}{400\pi }=4\pi r^2\implies \cfrac{400\pi }{4\pi }=r^2 \\\\\\ 100=r^2\implies \sqrt{100}=r\implies \boxed{10=r} \\\\\\ \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\qquad \qquad V=\cfrac{4\pi \boxed{10^3}}{3}\implies V=\cfrac{4000\pi }{3}$
