Is x+by-z a monomial, binomial or trinomial?
Ierofanga [76]

Answer:

This would be a trinomial.

Step-by-step explanation:

This is because X is number 1, b(y) is the second number, and -Z is the third.

In a trinomial, there are three numbers.

I hope this helps :)

PLEASE HELP WITH THIS

Answer:

Step-by-step explanation:

Start with this equation where 17 is the base, x is the power that 17 must be raised to. Then 2 is the result.

17^x = 2                      Take the log of both sides

log(17^x) = log(2)        Take the x outside the brackets

x log(17) = log(2)         Divide by log 17

x = log(2)/log(17)         Find the values for log  2 and log 17

log(2) = 0.3010

log(17) = 1.230

x = .3010/1.230

x = .2446

Solve f´(2) if f(x) = x^3 – 6x^2 + 9x + 3
Luba_88 [7]

Step-by-step explanation:

f(x) = x³ − 6x² + 9x + 3

Take the derivative and evaluate at x = 2.

f'(x) = 3x² − 12x + 9

f'(2) = -3

Check for local minimums or maximums by setting f'(x) equal to 0.

0 = 3x² − 12x + 9

0 = x² − 4x + 3

0 = (x − 1) (x − 3)

x = 1 or 3

Evaluate f(x) at the critical values, and at the end points.

f(0) = 3

f(1) = 7

f(3) = 3

f(5) = 23

f(x) has a minimum of 3 and a maximum of 23.

Please what is the answer
notsponge [240]

Answer:

A. x = 6

Step-by-step explanation:

I know this can look intimidating. But don't let that stop you. First the little 2 above the x means 'squared' or 'to the power of'.

And all this is asking for is 'what squared = 36?' And square is really just a number times itself. For example 3 squared is 9, or 3 x 3 = 9. A really simple way to do this if you don't know the answer by looking at it is to just square root of 36. And you can do that on your calculator. (It is this little symbol, √) and you just click 36 and then √ and it should give you 36. And then to check if you are right, just do 6 squared, or 6 x 6.

Good luck!
