The function f(x)= 1 divided by x is an example of an exponential function. true false

This is a false statement.

Exponential functions are when there is a variable in the exponent. With x being in the denominator, this is the same as the function x^-1. Since the exponent is a number and not a variable, it is not a exponential function.

26. If the area of the rectangle shown below is given by the expression 3x + 7x - 6,
Crazy boy [7]

Answer:

D=(3x-2)

Step-by-step explanation:

Area=length×width =3x²+7x-6

thus a=3 b=7 c=-6

W=(x+3)

since c is -6 it has to be the product of 3(from W)=-2

since a=3 multiply by x (from W) 3×x=3x

=3x-2

check if its correct.

3x-2×x+3

x(3x-2)+3(3x-2)

3x²-2x+9x-6

3x²+7x-6 thus its true

A scientist running an experiment starts with 100 bacteria cells. These bacteria double their population every 15 hours. Find ho
emmasim [6.3K]

Answer

It will take (t) = 24 hours to reach 300 .

Step by step explanation

It doubles every 15 hours.  initial bacteria = 100

We need to find how long it take for the bacteria cells to increase to 300.

300 = 100(2)^t/15

300/100 = 2^t/15

3 = 2^t/5

Taking "ln" both sides, we get

ln(3) = t/15 ln(2)

t/15 = ln(3)/ln(2)

t/15 = 1.585

t = 1.585 * 15

t = 23.78 hours

t = 24 hours to nearest whole hours.

Thank you.

What is the recursive formula for the sequence?<br><br> 8, 6, 4, 2, 0, . . .
e-lub [12.9K]

Step-by-step explanation:

Here 6 - 8 = 4 - 6 = 2 - 4 = 0 - 2 = - 2

Thus, the common difference between any two consecutive term is - 2.

The recursive formula is given as:

f(1)=a_1 = 8\\\\f(2)=a_2 = a_1 - 2\\\\f(3)=a_3 = a_2 - 2\\\\f(4)=a_4 = a_3 - 2\\\\f(5)=a_5 = a_4 - 2\\\\\therefore f(n) = a_n=a_{n-1}-2 \\

A box with a square base and open top must have a volume of 13,500 cm3. Find the dimensions of the box that minimize the amount
Alex17521 [72]

Answer:

Step-by-step explanation:

Let the side of the square base be x

h be the height of the box

Volume V = x²h

13500 = x²h

h = 13500/x² ..... 1

Surface area =  x² + 2xh + 2xh

Surface area S =  x² + 4xh  ...... 2

Substitute 1 into 2;

From 2; S =  x² + 4xh

S = x² + 4x(13500/x²)

S = x² + 54000/x

To minimize the amount of material used; dS/dx = 0

dS/dx = 2x - 54000/x²

0 = 2x - 54000/x²

0 = 2x³ - 54000

2x³ = 54000

x³ = 27000

x = ∛27000

x = 30cm

Since V = x²h

13500 = 30²h

h = 13500/900

h = 15cm

Hence the dimensions of the box that minimize the amount of material used is 30cm by 30cm by 15cm
