Francis owns a camping supply store and just put in an order for flashlights and sleeping
Harlamova29_29 [7]

Answer:

The number of sleeping bags bought is 17.

Step-by-step explanation:

If we let "x" be the number of the sleeping bags that were bought, we can make the following equation....

(5x)(12) + (x)(45) = 1785

By solving the equation we get....

(5x)(12) + (x)(45) = 1785

60x + 45x = 1785

105x = 1785

x = 1785 / 105

x = 17

There for the number of sleeping bags bough is 17.

The correct statement regarding the quadratic function is:

K. I, II and III.

<h3>What is a quadratic function?</h3>

A quadratic function is given according to the following rule:

y = ax^2 + bx + c

If a > 0, it has a maximum value, and if a < 0, it has a minimum value.

The extreme value is (x_v,y_v), in which:

  • x_v = -\frac{b}{2a}
  • y_v = -\frac{\Delta}{4a}
  • \Delta = b^2 - 4ac

The solutions are:

  • x_1 = \frac{-b + \sqrt{\Delta}}{2a}
  • x_2 = \frac{-b - \sqrt{\Delta}}{2a}

In this problem, we have a function h(t). Changing the coefficient c, the h-intercept h(0) changes. Looking at the formulas in the bullet point, the value of \Delta changes, meaning that both the maximum value y_v and the t-intercepts t_1 and t_2 will change, so option K is correct.
