Answer:

$32$ $or~2^5$

Step-by-step explanation:

→ $(2^3)(2^2)$

$=2^3*2^2$

$=(2*2*2)*(2*2)$

$=2*2*2*2*2$

$=32$

neonofarm [45]

Answer:

1.) $640 2.) 7 years.

Step-by-step explanation:

1000 x .2 = 200 1 yr

1000 - 200 = 800

800 x .2 = 160 2 yrs

800 - 160 = 640

640 x .2 = 128 3 yrs

640 - 128 = 512

ANYWAYS THIS WOULD TAKE TO LONG! SO HERE IS THE ANSWER TO B.

What is the quadratic function f(x)=x^2+6x-2 In vertex form?

Yuliya22 [10]

Answer: Option D

$f(x)=(x+3)^2 -k$

Step-by-step explanation:

For a quadratic function of the form

$ax ^ 2 + bx + c$

The x coordinate of the vertice is:

$x =-\frac{b}{2a}$

In this case the function is:

$f(x)=x^2+6x-2\\\\$

So

$a=1\\b=6\\c=-2$

The x coordinate of the vertice is:

$x=-\frac{6}{2*1}\\\\x=-3$

The y coordinate of the vertice is:

$f(-3) = (-3)^2 +6(-3) -2\\\\f(-3)=-11$

The vertice is: (-3, -11)

The form e vertice for a quadratic equation is:

$f(x)=(x-h)^2 +k$

Where

the x coordinate of the vertice is h and the y coordinate of the vertice is k.

Then h=-3 and k =-11

Finally the equation $f(x)=x^2+6x-2\\\\$ in vertex form is:

$f(x)=(x+3)^2 -k$
