Answer:

$4x^3-2x^2+5x-6+\frac{1}{x}$ is a polynomial

Step-by-step explanation:

a polynomial is a set of numbers with multiple terms that are not simplify able

$9x^7y^{-3} z$ is not a polynomial because its actually one term, there is no addition/subtraction of different terms.

-13 is a single number, so not a polynomial

13x^-2 is also a single number, not a polynomial

What equation represents an exponential function that passes through the point (2, 80)?

Marina86 [1]

Answer:

$f(x) = (4\sqrt{5})^{x}$

Step-by-step explanation:

The exponential function looks like the following: $f(x) = b^{x}$ .

If the function passes through the point (2, 80), then:

$f(x) = b^{x}$ → $80 = b^{2}$

Solving for 'b':

$b = \sqrt{80}$ → $b=4\sqrt{5}$

Then, the equation of exponential function that passes through the point (2, 80) is: $f(x) = (4\sqrt{5})^{x}$

Trevor took one of his friends out to lunch. The lunches cost $248.40 and he paid 12.5% sales tax. If Trevor left a 15% tip on t

bixtya [17]

He paid ...

-- The cost of the lunches (100% = 1.00 of it)

-- 15% of the cost as a tip (15% = 0.15 of it)

-- 12% of the cost as sales tax (12% = 0.12 of it)

Total that he paid = (1.00 + 0.15 + 0.12) = 1.27 of $248.40

= $315.47 .

Trevor is one generous guy !

For thanksgiving, you made 32 cupcakes. How many cupcakes were leftover if your family ate 3/4 of them?

Anvisha [2.4K]

All you need to do is divide 32 by 4.

32/4= 8

So, 3*8= 24 (that is 3/4 of the cupcakes)

32-24= 8

8 is the answer.

I hope this helps!
