Answer:

A, The vertex form of the equation is f(x) = (x + 5)² + 8. The standard form of the equation is f(x) = x² + 10x + 33

Step-by-step explanation:

the vertex form is, as you stated: a(x - h)² + k, where (h,k) is the vertex of the parabola

we are given the vertex (-5,8), so we plug in these values into the equation:

(x + 5)² + 8 (positive 5 on the inside because we are given a -5 and the original equation has a negative on the inside)

to get it into standard form, we can FOIL out (x+5)² to expand the equation, and that gives us:

x² + 10x + 25

now we add 8 to 25 because we cant forget that

x² + 10x + 33 is our equation, meaning the answer is A

A.) write an exponential expression: let 10 be the base and an even number between 1 and 10, be the exponent.
AfilCa [17]

Answer:

  10^2 . . . . see below for additional information or versions of the answer(s)

Step-by-step explanation:

You seem to want 10^<em>exponent</em>, where <em>exponent</em> is an even single digit, not zero.

We choose <em>exponent</em> = 2, so your expression is ...

  10^2

__

There are several versions of expanded form. One uses exponents. In that form, the expression above <em>is the expanded form</em>.

Another uses multipliers of 1, 10, 100, 1000, and so on. In that form, the expression expands as ...

  10^2 = 1×100

Another expanded form uses individual digits of the expanded form with others set to zero

  10^2 = 100

The standard form is ...

  10^2 = 100.

_____

We suppose your exponential expression might have another multiplier, such as 2.98:

  • exponential expression: 2.98×10^2
  • standard form: 298
  • expanded form 1: 2×10^2 + 9×10^1 +8×10^0
  • expanded form 2: 2×100 +9×10 +8×1
  • expanded form 3: 200 + 90 + 8
