Which of the following functions shown in the table below is not an exponential function?
kramer

Answer:

B. f(x)

D. h(x)

Step-by-step explanation:

An exponential function will have a common ratio.

We check and see if the consecutive terms has a common ratio.

For f(x),

\frac{5}{2}  \ne \frac{10}{5}

This is not an exponential sequence.

For g(x), we have:

\frac{2}{1}  =  \frac{4}{2}  =  \frac{8}{4}  = 2

For h(x),

\frac{1.25}{1}  \ne \frac{1.5}{1.25}

This is not an exponential sequence

For k(x),

\frac{16}{64}  =  \frac{4}{16}  =  \frac{1}{4}  =  \frac{0.25}{1}

Mnenie [13.5K]

No, having the greater rate of change does not mean a function will necessarily reach an output with the smallest input. It also depends on the initial values of the functions. If Jeremy's aunt lives closer to school, Jeremy's rate of change is smaller, but he could still get to school before Amy.

Set his alarm with a probability of 0.10. If he sets the alarm, it will wake him on time to make his first class with a probabil
Tomtit [17]

Answer:

C) 0.880

B) 0.075

Step-by-step explanation:

If the professor forgets to set the alarm

Probability = 0.1,

Wakes up in time probability = 0.25.

If the professor sets the alarm

Probability = 1 - 0.1 = 0.9

Wake up in time probability = 0.95.

A.)

The probability that professor Moore wakes up in time to make his first class tomorrow

Probability = ( Forgets to set alarm probability x Wakes up in time )+ ( Sets the alarm probability x Wakes up in time ) = ( 0.1 x 0.25 ) + ( 0.9 + 0.95 ) =  0.88

B.)

Late in the class

Set the Alarm Probability = 0.1

Wakes up late probability = 1 - 0.25 = 0.75

Professor Sets the alarm probability = Set the Alarm Probability x Wakes up late probability  = 0.1 x 0.75 = 0.075

Match each operation involving f(x) and g(x) to its answer.
galben [10]
F(x)=1-x² and g(x)=√(11-4x)

(g+f)(2)=>

 1-(2)²+√(11-4(2))

=√3-3

(f/g)(-1)

(1-(-1)²)/(√(11-4(-1))

=0

(g-f)(-1)

√(11-4*-1)-(1-(-1)²

=√15

(g×f)(2)

1-(2)²×√(11-4(2))
