The axis is symmetry for the function f(x) = -x^2-10+16 is x=-5.....

Aleksandr [31]

Axis of symmetry is the line x = h, where (h, k) is the vertex. Plug -5 into the equation to get k.

f(-5)=-(-5)^2-10(-5)+16=-25+50+16=41

(-5, 41)

(40s+100t) divid by 10

Olenka [21]

Answer:

=4s+10t

Step-by-step explanation:

4s has no like terms so we divide by 10 and that gives us 4.

100t has no like terms so we divide 100 by 10 that gives us 10. This means that our total answer is (4s+10t). Hope this helped! If it did can I have brainliest thx.

Write a polynomial function f of least degree that has a leading coefficient of 1 and the given zeros. Write the function in sta

NeX [460]

Answer:

$f(x)=x^3+(3+\sqrt{5})x^2+(6\sqrt{5}-18)x$

or

$f(x)=x^3+3x^2+\sqrt{5}x^2-18x+6\sqrt{5}x$

Step-by-step explanation:

A polynomial function with 3 zeroes is going to be of degree 3, so we're going to have at least least 3 factors of the form $x-a$ , where <em>a </em>is a zero of the function. For three zeroes <em>a</em>, <em>b</em>, and <em>c</em>, we'd have the factors $x-a,\ x-b,$ and $x-c$ , making our function look like

$f(x)=(x-a)(x-b)(x-c)$

Substituting our roots for a, b, and c:

$f(x)=(x-(-6))(x-0)(x-(3-\sqrt{5}))\\=(x+6)(x)(x-3+\sqrt{5})$

To write this function in standard form, we can expand from left to right:

$f(x)=(x^2+6x)(x-3+\sqrt{5})\\=(x^2+6x)x-(x^2+6x)3+(x^2+6x)\sqrt{5}\\=x^3+6x^2-3x^2-18x+\sqrt{5}x^2+6\sqrt{5}x\\=x^3+3x^2+\sqrt{5}x^2-18x+6\sqrt{5}x$

At this point, we could either leave it as is, or group the coefficients for the $x^2$ and $x$ terms to get

$f(x)=x^3+(3+\sqrt{5})x^2+(6\sqrt{5}-18)x$
