No, 763,400 rounded to the nearest ten thousand is 760,000 because the digit in the thousands place value (3) is less than 5, so you underestimate

The student if definitely incorrect because you are rounding from the 3rd digit ( the 3 in 763,400) It is bellow 5, only numbers above 5 will round up.

HELP PLEASE EQUATION OF PARABOLA

Masteriza [31]

It has a minimum value at x = 3 and f(x) = 4

Vertex form is

f(x) = a(x - 3)^2 + 4 where a is some constant to be found

From the graph when x = 5 f(x) = 15, so

15 = a * 2^2 + 4

a = 15-4/4 = 11/4

so our equation is f(x) = 11/4(x - 3)^2 + 4

Apply the properties of exponents to rewrite each expression in the form kxn, where nn is an integer and x ≠0

Answer:

The expression will be $0.333x^{-2}$

Step-by-step explanation:

We have given expression $\frac{x^{-3}x^5}{3x^4}$

We know the property of exponent that when two function are divided then the power of exponent is subtracted and when there is multiplication of two function then exponent is added

So $\frac{x^{-3}x^5}{3x^4}=\frac{x^{2}}{3x^4}=0.333x^{-2}$
