Y = 3(x-2)^2 + 5
Orlov [11]

The y-intercept coordinate is at the point (0, 17)

<h3>Properties of functions</h3>

Given the following function expressed as:

y = 3(x-2)^2 + 5

  • The vertex of the function (h, k) is (2, 5) while the axis of symmetry is at x = 2
  • Domain are the input values for which the function exist. According to the function, the domain and  range exists on all real values

The x-intercept is the point where y = 0

3(x-2)^2 + 5=0\\3(x-2)^2  = -5\\(x-2)^2 = -5/3\\x - 2 = 25/9\\x = 25/9 + 2\\x = \frac{43}{9}

Hence the x-intercept is (43/9, 0)

The y-intercept is the point where x = 0

y=3(x-2)^2 + 5\\y=3(-2)^2 + 5\\y=12+5\\y=17

The y-intercept coordinate is at the point (0, 17)

If sea water contains 3.5% of salt. How much seawater do you need in order to get 17.5 lb of salt?
CaHeK987 [17]

Answer:

500 lb

Step-by-step explanation:

Let x lb be the weight of seawater needed to get 17.5 lb of salt.

Now,

x lb - 100%

17.5 lb - 3.5%

Write a proportion:

\dfrac{x}{17.5}=\dfrac{100}{3.5}

Cross multiply:

x\cdot 3.5=100\cdot 17.5\\ \\x=\dfrac{100\cdot 17.5}{3.5}=500\ lb
