Answer:

465.75 or 465.8 rounded to the nearest tenth

Step-by-step explanation:

You would multiply 16.2 and 14.5 and divide by 2 to get 117.45. You then multiply by 3 for the 3 sides to get 352.35. Lastly, to find the area of the base you would need to multiply 16.2 and 14 and divide it by two to get 113.4. Add it with the 3 sides and you get 465.75.

The function f(x)=3x+12x+11 can be written in vertex form as?

solmaris [256]

y = -3(x - 2)^2 + 1 x-coordinate of vertex: x = -b/(2a) = -12/-6 = 2 y-coordintae of vertex: y(2) = -12 + 24 - 11 = 1 Vertex form: y = -3(x - 2)^2 + 1 Check. Develop y to get back to standard form: y = -3(x^2 - 4x + 4) + 1 = -3x^2 + 12x - 11.

Solve the following equation. 2/3x + 6 = 1/2x + 1/4x 2 6 14 2/5 72

Answer: 72
heyy, umm basically group like terms together. E.g. 6= 1/2x + 1/4x - 2/3x. Then, just solve for x e.g. 1/2 + 1/4 - 2/3 and use the answer to equal it to 6. Which should be 1/12x=6... pretty sure haha. Then divide. E.g.6/1/12 for x. In this case I got 72.. :)

Let \[f(x) = \frac{3x - 7}{x + 1}.\]find the range of $f$. give your answer as an interval.

ra1l [238]

Hello :
let : $y= \frac{3x-7}{x+1}$
calculate : x ......x ≠ -1
 $y(x+1) = 3x-7$
$yx+y =3x-7$
$yx-3x = -y-7$
$x(y-3) = -7-y$
$x = \frac{y+7}{3-y}$
the inverse function is : $g(x) = \frac{x+7}{3-x}$
domain of : g is the range of : f
as an interval : ]-∞: 3 [U ]3;+∞[

Mia is finally able to upgrade her cellphone. The one she wants costs $220 but she is able to get it for 60% off. She has a coup

Kay [80]

The answer would be A) $79.20

(220*.4).9 as 60 percent off means that the product is only 40 percent of its original value, furthermore, we multiply the entire thing by .9

I NEED HELP!! please show all work

PtichkaEL [24]

Take the logarithm of both sides. The base of the logarithm doesn't matter.

$4^{5x} = 3^{x-2}$
