A class trip cost a total of $414, including a museum ticket and lunch for each student. Three students were sick on the day of

the trip and did not attend, so the total cost dropped to $360. How many students went on the trip?

Answer:

20

Step-by-step explanation:

we know that 414-360 = 54 and we divide it by 3, 54/3 = 18. So we know that every student paid 18 dollars. 360/18 = 20

  • Let total students be x
  • Students didn't came to lunch be y

ATQ

  • x+y=414---(1)
  • x-y=360--(2)

Substracting both

\\ \sf\longmapsto 2y=54

\\ \sf\longmapsto y=27

  • 3 students paid 27

each paid

\\ \sf\longmapsto \dfrac{27}{3}=9

Now

Total students went on trip

\\ \sf\longmapsto \dfrac{360}{9}

\\ \sf\longmapsto 40

The equation of a quadratic is =2^2+3−2and after you factorizing 2^2+3−2=0you got x = -2 and x = 1/2 and the curve crosses the y
Lelechka [254]

Given the next quadratic function:

y=2x^2+3x-2

to sketch its graph, first, we need to find its vertex. The x-coordinate of the vertex is found as follows:

x_V=\frac{-b}{2a}

where <em>a</em> and <em>b</em> are the first two coefficients of the quadratic function. Substituting with a = 2 and b = 3, we get:

\begin{gathered} x_V=\frac{-3}{2\cdot2} \\ x_V=-\frac{3}{4}=-0.75 \end{gathered}

The y-coordinate of the vertex is found by substituting the x-coordinate in the quadratic function, as follows:

\begin{gathered} y_V=2x^2_V+3x_V-2 \\ y_V=2\cdot(-\frac{3}{4})^2+3\cdot(-\frac{3}{4})-2 \\ y_V=2\cdot\frac{9}{16}+3\cdot(-\frac{3}{4})-2 \\ y_V=\frac{9}{8}-\frac{9}{4}-2 \\ y_V=-\frac{25}{8}=-3.125 \end{gathered}

The factorization indicates that the curve crosses the x-axis at the points (-2, 0) and (1/2, 0). We also know that the curve crosses the y-axis at (0,-2). Connecting these points and the vertex (-0.75, -3.125) with a U-shaped curve, we get:
