Can someone help me find the diameter? <br><br> also what is a diameter even?
lukranit [14]

Answer:

24

Step-by-step explanation:

area of circle = πr²

πr² = 144π

Cancel out π

r² = 144

r = √144

r = 12

diameter = 2 x radius

diameter = 2 x 12

diameter = 24m

* diameter is the "width of a circle", the distance from the widest points of the circle

Let f(x)=18/1+3^e-0.1x What is the point of maximum growth rate for the logistic function f(x)? Show all work. Round your answer
xz_007 [3.2K]

Answer:

(0, 4.5)

Step-by-step explanation:

*The equation can be put into Desmos, to find the point, but the work to prove it is here*

f(x)=c/1+Ae^-Bx

Y=C

C=18      A=3      -B=-0.1

*Replace x with 0 in the equation, so you know 0 is the x value, and it leads you to the y value*

f(0)=18/1+3e^-o.1(0)

= 18/1+3e^0

=18/1+3(1)

=18/1+3

=18/4

=4.5

x=0    y=4.5

Maximum growth rate = (x,y) --> (0, 4.5)

Hope this helps:))!!

I need help on 34 and 36
aleksley [76]
34. 65 = 3/4c - 7....add 7 to both sides
      65 + 7 = 3/4c...simplify
       72 = 3/4c...multiply both sides by 4/3, eliminating the 3/4 on the left
       72 * 4/3 = c
       288/3 = c
       96 = c

36. -5/2 = 3/4z + 1/2 ...subtract 1/2 from both sides
      -5/2 - 1/2 = 3/4z .... simplify
       -6/2 = 3/4z ....reduce
       -3 = 3/4z....multiply by 4/3. eliminating the 3/4 on the left
      -3 * 4/3 = z
       -12/3 = z
       -4 = z
