Step-by-step explanation:

<u>Given</u>

  • DE = 3x + 2, EF = x + 5, DF = 23

<u>As per segment addition postulate</u>

  • DE + EF = DF

<u>Substituting values:</u>

  • 3x + 2 + x + 5 = 23
  • 4x + 7 = 23
  • 4x = 16

If a bacteria population starts with 80 bacteria and doubles every four hours, then the number of bacteria after t hours is n =
Over [174]

Answer:

Step-by-step explanation:

given that a bacteria population starts with 80 bacteria and doubles every four hours,

The function representing the number of bacteria after t hours

= n=f(t) = 80*2^{\frac{t}{4} }

We are to find the inverse of the function

i.e. we must make t = g(n) where g is a function of n.

Take log on both sides.

ln n =ln80+\frac{t}{4} ln 2\\\frac{t}{4} =\frac{ln\frac{n}{80} }{ln 2} \\t = 4\frac{ln\frac{n}{80} }{ln 2}

this is the inverse function.

Classify the events as dependent or independent. the events of getting two aces when two cards are drawn from a deck of playing
Thepotemich [5.8K]
The events are dependent. 

When the first card is not replaced, you change the probability of the second card.  At the very least, you have changed the total number of cards to draw from.

A rectangle has a length that is 5 inches greater than its width, and its area is 104 square inches. The equation (x + 5)x = 104
mina [271]
1. Regroup terms
x(x+5)=104

2. Expand
x^2+5x=104

3. Move all terms to one side
x^2+5x-104=0

4. Factor x^2+5x-104
(x-8)(x+13)=0

5. Solve for x
x=8 or x=-13
Since x<0 is not possible in this case, x=8

6. Finding the dimensions
We know that one side has to be x+5, and now that we know x:
8+5=13
13*8=104

The dimensions are 13 and 8, have a nice day :D
