Monthly rate of growth = x
then
(1+x)^12 = 100%-8%
(1+x) = (0.92)^(1/12)=0.9930756
=>
x=0.9930756-1=-0.0069244 = -0.69244%

5. What is the multiple zero and multiplicity of f(x) = (x + 4)(x - 2)(x + 4)(x + 4)?
natali 33 [55]

The zeros of this functions are -4, 2, -4, and -4.

-4 is a multiple zero and has multiplicity 3.

2 is a zero.  I would call it a simple zero, since it's only a zero once (AKA has multiplicity of 1).

Is this a "pick one answer" or "pick all correct answers"?

He floor of a moving van is 3 feet off of the ground. The ramp into the van makes a 12° angle with the ground. About how long is
soldier1979 [14.2K]

Given :

Hight of the van from the ground, h = 3 feet.

The ramp into the van makes a 12° angle with the ground.

To Find :

How long is the ramp.

Solution :

Let, length of ramp is l .

So, height of ramp in terms of length is given by :

h = l \times sin\ 12^o\\\\l = \dfrac{h}{sin \ 12^o}\\\\l = \dfrac{3}{sin \ 12^o}\\\\l = 14.429 \ feet

Hence, this is the required solution.

Verify the identity. cos (x - y) - cos (x + y) = 2 sin x sin y
ra1l [238]
It is already in identity.
cos (x - y) - cos (x + y) = 2 sin(x) sin (y)

Let f(x)=4x+9. Write a function g whose graph is a reflection in the y-axis of the graph of f. g(x)= ?
frez [133]

Answer:

g(x)=-4x+9

Step-by-step explanation:

So we know that:

f(x)=4x+9

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

g(x)=f(-x)=4(-x)+9

Simplify:

g(x)=-4x+9

And that's our answer :)
