Answer:

49

Step-by-step explanation:

The ratio of three numbers = 2:5:7

Then the numbers are 2x,5x and 7x

Given that the LCM of these numbers  = 490

LCM of 2x,5x,7x is 2×5×7×x = 70x

Then, we have 70x = 490

x  = 7

Hence, the numbers are 14, 35 and 49

Largest number = 49

∴The square root of the largest number = 7

I'm trying to evaluate and solve this quadratic function and I get so lost on word problems I will include a picture
SashulF [63]

Given:

The Revenue function R(x):

R(x)\text{ = 550x}

The cost function C(x) :

C(x)=1240+2x^2

Solution

1. Profit is the difference between the revenue and the cost. Hence, the Profit function P(x) is:

\begin{gathered} P(x)\text{ = R(x) - C(x)} \\ =550x-(1240+2x^2) \\ =550x-1240-2x^2 \end{gathered}

2. The vertical intercept of P(x) can be obtained by substituting x =0 into P(x)

\begin{gathered} P(x)=550x-1240-2x^2 \\ P(0)\text{ = 0 -1240 -0} \\ P(0)\text{ = -1240} \end{gathered}

Ordered Pair : (0, -1240)

If the company sells no items, they would lose $ 1240
