1. IF the function f(x) = 2(x – 3)2 – 4 is shifted vertically three units up and horizontally

Answer:

I believe it is 2(x-5)²−1

Step-by-step explanation:

The parentheses represent the horizontal shift. (X-__) is a shift to the right. (X+__) is a shift to the left. The last number of the function is the vertical shift. A negative number is shifting down and a post number is shifting up.

So, if the graph shifts up three units, then you add 3 + -4 to get -1. And if the graph shifts right 2 units, then you subtract 2 from -3 to get -5.

antiseptic1488 [7]

Answer:

<h2>C.</h2>

Step-by-step explanation:

Look at the pictures.

x - sausage

y - bacon

A. 20 pounds of sausage and 90 pound of bacon

x = 20 → y = 100 > 90

B. 40 pound of sausage and 40 pound of bacon

x = 40 → y = 75 > 40

C. 60 pound of sausage and 80 pound of bacon

x = 60 → y = 50 < 80

D. 80 pound of sausage and 20 pound of bacon​

x = 80 → y = 25 > 20

The radius of a circle is 10. Using π, which equation expresses the ratio of the circumference of the circle to the circle's dia
aleksley [76]

The ratio of circumference to diameter is independent of the radius.



Defining C=circumference, r=radius, D=diameter =  2r



Circumference = C = 2 &pi; r = &pi; D  


=> 


ratio of circumference / diameter


= C/D = &pi;

An audiometer produces a pure tone with a frequency f of 1200 hertz (cycles per second). The maximum pressure P produced from th
Scilla [17]

Answer: Pressure(t) = 5mP*sin(191.08*t)

Step-by-step explanation:

The information we have:

Maximum pressure P = 5 mP

frequency = 1200Hz

Period = 1/frequency = (1/1200) seconds

when t = 0, P = 0, so we should use a sin function (because sin(0) = 0)

Then we can write this as:

Pressure(t) = P*sin(c*t)

where t is time in secnds, P is the maximum pressure 5mP, and c is a constant that depends on the period.

Pressure(t) = 5*sin(c*t)

knowing that the period is 1/1200 seconds, we have that:

c*1/1200 s = 2*3.14

c = 1200/(2*3.14) 1/s= 600/3.14 1/s

Our function is

Pressure(t) = 5mP*sin(191.08*t)
