I think the answer is B

Answer:

Option B.

Step-by-step explanation:

The given polynomial is

10x^7-9x^2+15x^3+9

In standard form of a polynomial, the terms are arranged according to its degree from left to right. It means term with highest degree should be on the left side.

Degree of 10x^7,-9x^2,15x^3\text{ and }9 are 7, 2, 3 and 0.

Arrange the terms according to its degree.

10x^7+15x^3-9x^2+9

Hence, the correct option is B.

How do the graphs of the functions f(x)=<img src="https://tex.z-dn.net/?f=%28%5Cfrac%7B3%7D%7B2%7D%29%5Ex" id="TexFormula1" titl
grin007 [14]

Step-by-step explanation:

f(x) = (3/2)ˣ

g(x) = (2/3)ˣ

These are examples of exponential equations:

y = a bˣ

If b > 1, the equation is exponential growth.

If 0 < b < 1, the equation is exponential decay.

So f(x) is an example of exponential growth, and g(x) is an example of exponential decay.

Also, 2/3 is the inverse of 3/2, so:

g(x) = (3/2)^(-x)

So more specifically, f(x) and g(x) are reflections of each other across the y-axis.

Is this a function or not​
Marta_Voda [28]

Answer:

No, I don't think so.

Step-by-step explanation:

I don't think this is a function because the triangle is made of multiple points. Some of these points share the same <em>x</em> point, so this concludes that a triangle on a graph is not a function.

Hope it helps!

PLEASE HELP!
Andru [333]
I = PRT

14,300 = (700)(0.0725)(t)
14,300 = 50.75(t)
14300/50.75 = t
281.77 = t    or    t = 281.77

hope this helps :)
