Given f(x) = 3x3 + 8x2 – 10x – 12, find f(3). A) f(3) = 84 B) f(3) = 96 C) f(3) = 111 D) f(3) = 123

andre [41]

Answer:

C) f(3) = 111

Step-by-step explanation:

f(x) = 3x^3 + 8x^2 – 10x – 12

Let x=3

f(3) = 3(3)^3 + 8(3)^2 – 10(3) – 12

=3*27+8(9) -30-12

=81+72-30-12

=111

Write the equation of a circle with the following pints in the picture using the completing the square method. Thanks

pantera1 [17]

So hmm notice the picture below

you have the center, and a point on the circle... all you need is the radius

$\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ -2}})\quad 
% (c,d)
&({{ 3}}\quad ,&{{ -4}})
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}\leftarrow r$

then use that radius in the circle's equation

$\bf (x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2
\qquad center\ ({{ h}},{{ k}})\qquad
radius={{ r}}$

John wants to buy a new laptop computer the computer store sells laptops for $480 or 9 credit payments of $58 how much interest

Neko [114]

First you would need to find out how many 9 payments of 58$ would be and that is 522. Then you would need to subtract the 522 and the 480 and your answer would be 42$ so the interest would be 42$
