4.125\ is\ rational\ number\ because\ we\ can\ convert\ this\ number\\to\ the\ fraction\ \frac{p}{q}\ where\ p,\ q\in\mathbb{Z}:\\\\4.125=\frac{4.125}{1}=\frac{4.125\cdot1,000}{1\cdot1,000}=\frac{4,125}{1,000}

What is the following product? RootIndex 3 StartRoot 16 x Superscript 7 Baseline EndRoot times RootIndex 3 StartRoot 12 x Supers
Nadya [2.5K]

Answer:

4x^5\sqrt[3]{3x}

Step-by-step explanation:

I'm not sure I understand the problem, but I think it's this:

\sqrt[3]{16x^7} \times \sqrt[3]{12x^9} =

= \sqrt[3]{16 \times 12 \times x^{16}}

= \sqrt[3]{192 \times x^{15} \times x}

= \sqrt[3]{64 \times 3 \times (x^5)^3 \times x}

= \sqrt[3]{4^3 \times 3 \times (x^5)^3 \times x}

= 4x^5\sqrt[3]{3x}

If a cube-shaped cell is 3 units tall by 3 units wide and 3 units long, what is the cell's surface-area-to volume ratio?
bulgar [2K]
The cube has 6 sides, each a square with dimensions 3 by 3, 

the area of any of these squares is 3*3=9 square units.

The total area of the cube is 6*9 square units=54 square units


The volume of a cube with side length a is given by : \displaystyle{ V_{cube}=a^3, thus the volume of the cube-shaped cell is 3*3*3=27 cube units.


(surface area):(volume)=54:27 = 2:1 =2

Answer: 

the ratio of the numerical values is 2

(their ratio including units is 2/unit

The number of bacteria in a culture is given by the function n(t) =950e^0.45t Where t is measured in hours A) what is the contin
tatiyna

Answer:

a) The continuous rate of growth of this bacterium population is 45%

b) Initial population of culture at t = 0 is 950 bacteria

c) number of bacterial culture contain at t = 5 is 9013 bacteria

Step-by-step explanation:

The number of bacteria in a culture is given by

n(t) = 950e^{0.45t}

a) rate of growth is

Bacteria growth model N(t) = noe^{rt}

Where r is the growth rate

hence r = 0.45

              = 45%

b) Initial population of culture at t = 0

n(0) = 950e^{0.45(0)}

       = 950e^{0}

       = 950 bacteria

c) number of bacterial culture contain at t = 5

n(5) =  950e^{0.45(5)}

      = 950e^{2.25}

      = 9013.35

      = 9013 bacteria

What is the y-intercept of the function f(x)=4 - 5x? (Hint: use the commutative property)
Tom [10]

Answer:

Therefore the y-intercept of the function is 4.

Step-by-step explanation:

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

y-intercept: The line or function which intersect at y-axis. So when the line intersect at y-axis, X coordinate is zero.

So in the given Function Put x = 0 we will get the y-intercept

f(x)= 4-5x

Put x =0

f(0)= 4-5\times 0

f(0)= 4-0=4

Therefore the y-intercept of the function is 4.
