Area of semicircle = 1/2 x pi x radius x radius
radius of semicircle = 14/2 = 7
pi = 3.14 for this question, so

1/2 x 3.14 x 7 x 7 = 76.93
area = 76.93

Answer:

area of a semi circle is 1/2 pi rsquare

since 14 is a diameter

to get the radius divide 14 by 2 =7

1/2* 3.14* 7*7

ans = 76.93

What is the y-intercept of f(x)=(1÷4)<br>

Hunter-Best [27]

Y-intercept means x=0 but judging from the question you only gave f(x) which means Y

And so I think the only valid answer there is

Y= 0.25
X=0

A circle has a circumference of 50.24 units.

Xelga [282]

8 units

Circumference = pi * 2 * radius
50.24 = 3.14 * 2 * radius
50.24 = 6.28 * radius
8 = radius

What is the multiple zero and multiplicity of f(x) = x3 + 10x2 + 25x?

elena-s [515]

Answer:

The multiple zero is $x=-5$ .

The multiplicity is 2

Step-by-step explanation:

The given function is

$f(x)=x^3+10x^2+25x$

To find the zero of this function, we equate it to zero.

$\Rightarrow x^3+10x^2+25x=0$

We factor to obtain;

$x(x^2+10x+25)=0$

Observe that; the expression within the parenthesis is a perfect square.

This implies that;

$x(x+5)^2=0$

This implies that;

Either $x=0$ or $(x+5)^2=0$

$(x+5)^2=0$ has a multiple zero which is

$x=-5$ and its multplicity is 2.
