What is the value of 4x to the third +4x if x is 4
weqwewe [10]
The correct answer of
4{x}^{2}  + 4x
if x=4 is 272.

to solve the equation if x equals 4, you must substitute the x of the 4.
4( {4}^{3} ) + 4(4)
then solve by order of operations.
solve what is inside the parentheses first
4(64) + 4(4)
then do the multiplication of the factors
256 + 16
then the final step, adding, to get the solution of 272

What is the volume of a picnic cooler that it 2ft wide, 3ft long, and 1 1/2 ft deep? PLZ HELP
olga_2 [115]
To find the volume of the picnic cooler, you multiply the three dimensions together.

(2 ft)(3 ft)(1 1/2 ft)
= (2 ft)(3 ft)(3/2 ft)
= 9 ft^3

The volume of the picnic cooler is 9 ft^3~

A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria,
DIA [1.3K]
Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000

Growth rate = r = 150% = 1.50 

The equation model for this situation is:

A= A_{o}(1+r)^{t}

Using the values in above equation, we can write:

45000000=100(1+1.5)^{t}  \\  \\ &#10;450000=(2.5)^{t} \\  \\ &#10;log(450000)=log((2.5)^{t})  \\  \\ &#10;log(450000)=t*log(2.5) \\  \\ &#10;t= \frac{log(450000)}{log(2.5)} \\  \\ &#10;t=14.21

This means, the person will fall sick after about 14 hours.

Given that f(a+b)= f(a) + f(b) and f(x) is always positive, what os the value of f(0)?
FrozenT [24]
This is a strange question, and f(x) may not even exist. Why do I say that? Well..

[1] We know that f(a+b) = f(a) + f(b). Therefore, f(0+0) = f(0) + f(0). In other words, f(0) = f(0) + f(0). Subtracting, we see, f(0) - f(0) = f(0) or 0 = f(0).

[2] So, what's the problem? We found the answer, f(0) = 0, right? Maybe, but the second rule says that f(x) is always positive. However, f(0) = 0 is not positive!

Since there is a contradiction, we must either conclude that the single value f(0) does not exist, or that the entire function f(x) does not exist.

To fix this, we could instead say that "f(x) is always nonnegative" and then we would be safe.
