To the nearest tenth of a centimeter, what is the circumference of a circle with a radius of 2.5 cm? (Use 3.14 for π.) a. 25.1 c

Alborosie

The circumfrence of a circle is $\pi d$
diamter is 2r ( Two times the radius )
So you would now have
$5 \pi$
\pi = 3.14
so
(3.14)(5) = 15.7
The answer is B, 15.7
In you question you wrote it as C

Write the quadratic function in the form f (x)= a (x - h)' + k.<br> f (x) = 3x² - 6x+6

Vlad1618 [11]

Answer:

$f(x) = 3(x - 1)^2-3$

Step-by-step explanation:

Given

$f(x) = 3x^2 - 6x + 6$

Required

Write as:

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

In $f(x) = 3x^2 - 6x + 6$ , the coefficient of x is -6

Divide by 2: -3

Square: 9

Add 9 - 9 to the above equation

$f(x) = 3x^2 - 6x +9-9+ 6$

Split to 2

$f(x) = [3x^2 - 6x +9]-[9- 6]$

$f(x) = [3x^2 - 6x +9]-[3]$

Factorize:

$f(x) = [3x^2 - 3x -3x+9]-[3]$

$f(x) = [3x(x - 1) -3(x-1)]-[3]$

$f(x) = [(3x - 3)(x-1)]-[3]$

Factorize 3x - 3

$f(x) = [3(x - 1)(x-1)]-[3]$

$f(x) = 3(x - 1)^2-[3]$

$f(x) = 3(x - 1)^2-3$

PLEASE HELP I AM STUCK ON THIS

Fofino [41]

Answer:

Step-by-step explanation:

This is a right triangle problem. The reference angle is x, the side opposite the reference angle is 32, and the hypotenuse is 58. The trig ratio that relates the side opposite a reference angle to the hypotenuse is the sin. Filling in accordingly:

$sin(x)=\frac{32}{58}$
