That statement is true, because a differentiable function must be continuous, and the only way to reach two relative maxima,, if the function does not have empty places or jumps, which is what continuity means, is that the graph bends between those two maxima and reach an intermediate minimum.

nirvana33 [79]

Answer:

z = -166

Step-by-step explanation:

1. Subtract 3 from both sides to get z/2 = -83

2. Multiply 2 by both sides to get z = -166

A bacteria culture grows with constant relative growth rate. The bacteria count was 1,920 after 4 hours and 1,966,080 after 12 h
attashe74 [19]

From the calculation, the growth rate is 0.88.

<h3>What is the growth rate?</h3>

To find the relative growth rate

P1 = Poe^rt

P2 = Poe^rt

Thus;

1920 = Poe^4r ------ (1)

1966080 =Poe^12r -------(2)

P2/P1 gives;

1966080/1920 = Poe^12r/Poe^4r

1024 = e^12r/e^4r

1024 =e^8r

1024 = (e^r)^8

2^10 = (e^r)^8

e^r = 2^1.25

e^r = 2.38

r = ln(2.38)

r = 0.88

The initial size of the culture is;

1920 = Poe^(0.88 * 4)

Po = 1920/e^(0.88 * 4)

Po = 57

The  expression for the exact number of bacteria after t hours is

P(t) = 57e^0.08t

The growth (in bacteria per hour) after 9.5 hours is

P(t) = 57e^(0.88 * 9.5)

P(t) = 243544

For the number to reach 72,000;

72,000 =  57e^0.88t

72,000/57 = e^0.88t

ln 126 = ln[e^0.88t]

4.8 = 0.88t

t = 4.8/0.88

t = 5.5 hours

Rebecca needs 10 1/2 yards of fabric to make a quilt. She has one piece of fabric that is 2 1/2 yards and another piece of fabri
klasskru [66]

Answer:

ans = 4

Step-by-step explanation:

he has 2 1\2 and 4 1\4

to find the ans, we must firstly find out his total amount of fabric, so we add the available fabric

first we add whole numbers

2 + 4 = 6

then we add fractions

1 1

--- + ---

2 4

2 + 1 3

------------- = ---

4 4

after we add the whole no and fraction

6 + 3\4 = 6 3\4

note 10 1\2 is greater than 6 3\4

so to find the part left, we

have

10 1\2 - 6 3\4

as our answer
