What quadratic function does the graph represent?

Mathematics
1 answer:
nekit [7.7K]3 years ago
5 0

Answer:

f(x)=-\frac{1}{3}(x-2)^2+4,

Step-by-step explanation:

The function of the graph can be written in the vertex form as

f(x)=a(x-h)^2+k, where V(h,k)=V(2,4) is the vertex of the quadratic function.

We substitute the value to obtain;

f(x)=a(x-2)^2+4,

The point (5,1) lies on the graph so we use it to determine the value of a.

1=a(5-2)^2+4,

1-4=a(3)^2,

-3=9a,

a=-\frac{1}{3}

The required equation is

f(x)=-\frac{1}{3}(x-2)^2+4,

An Artist has 600 inches of framing material to form a rectangular frame. The dimensions of the wall on which it will hang limit
kondor19780726 [428]

Answer:

  • 2(L +W) ≤ 600
  • W ≤ 200
  • L ≥ 2W

Step-by-step explanation:

We assume the problem wording means the length is to be at least 2 times <em>as long as</em> the width. (<em>Longer than</em> usually refers to a difference, not a scale factor.)

If we let "W" and "L" represent the width and length, respectively, then we can translate the problem statement to ...

  2(L + W) ≤ 600 . . . . . . the perimeter is twice the sum of length and width

  W ≤ 200 . . . . . . . . . . . . the width is at most 200 inches

  L ≥ 2W . . . . . . . . . . . . . the length is at least twice the width

What is 8 is increased to 22
SOVA2 [1]
<span><span>1.       </span>What is 8 increased to 22.
I believe you want me to show you what is the interest increased from 8 to 22
Let’s start the solution process:
=> 8 is the original number and supposed to be the 100% value
=> 22 is the increased number
subtract 22 by 8 to know how much is added.
=> 22 – 8 = 14
=> 14 / 8 = 1.75
=> 1.75 * 100% = 175%
Thus, the added increased is around 175% of the original money</span>

!! AP CALCULUS AB !!<br> find the limit of [(secx*sinx) + (cscx*cosx)]/(3secx) as x approaches 3pi/2
uysha [10]

f(x)= \frac{\frac{\sin{x}}{\cos{x}}+\frac{\cos{x}}{\sin{x}}}{3\sec{x}}

\frac{\frac{\sin{x}}{\cos{x}}+\frac{\cos{x}}{\sin{x}}}{3\sec{x}} \implies \\ \frac{\sin^2{x}+\cos^2{x}}{\sin{x}\cos{x}}\frac{\cos{x}}{3}\implies \\\frac{1}{\sin{x}\cos{x}}*\frac{\cos{x}}{3}\implies \\ \frac{1}{3\sin{x}}

So,

\lim_{x \rightarrow \frac{3\pi}{2}}{f(x)=f(\frac{3\pi}{2})=\frac{1}{3\sin{\frac{3\pi}{2}}}=-\frac{1}{3}
