A chef pours 550 cubic centimeters of batter into a baking pan in the shape of a right circular cylinder. If the pan has a radiu

serious [3.7K]

We know that
volume of a right circular cylinder=pi*r²*h
where
r ----> is the radius
h---> is the height

in this problem
r=6 cm
h=?
Volume=550 cm³
so
V=pi*r²*h------> h=V/[pi*r²]----> h=550/[3.14*6²]----> h=4.87 cm
<span>Round to the nearest tenth
</span>h=4.9 cm

the answer is
4.9 cm

Write a polynomial function in factored form with double roots at -2 and 5 and the constant term of the polynomial in standard f

Amanda [17]

Answer:

$f(x)=-0.4x^4+2.4x^3+8.4x^2-24x-40$

Step-by-step explanation:

If -2 and 5 are double roots of the polynomial function, then the function expression is

$f(x)=a(x-(-2))^2(x-5)^2\\ \\f(x)=a(x+2)^2(x-5)^2$

Rewrite this function in standard form:

$f(x)=a(x^2+4x+4)(x^2-10x+25)\\ \\f(x)=a(x^4-10x^3+15x^2+4x^3-40x^2+100x+4x^2-40x+100)\\ \\f(x)=a(x^4-6x^3-21x^2+60x+100)\\ \\f(x)=ax^4-6ax^3-21ax^2+60ax+100a$
