Answer:

Equation given in graph B → y = -3x² + 4

Step-by-step explanation:

Equation of the graph A,

y = 3x² - 3

We have to find the equation of the graph (parabola) given in graph (B).

Parabola given in graph B is the inverted form of graph A with vertex at (0, 4)

Therefore, equation of the parabola given in graph B will be,

y = -a(x - h)² + k

where negative notation of the coefficient a shows the inverted form of the parabola given in graph A and (h, k) will be the vertex.

y = -3(x - 0)² + 4

y = -3x² + 4

A circular garden has a circumference of 42.3 feet. Find the approximate diameter of the garden. Use 3.14 for π.
tamaranim1 [39]

Answer:

13.5

Step-by-step explanation:

c = 2πr

42.3 = 2(3.14)r

42.3 = 6.28r

6.74 = r

d = r + r

d = 6.74 + 6.74

d = 13.5

A survey showed that 30% of students bring their lunch to school. The survey polled 300 students. How many of the 300 students d
Karolina [17]

Let's first find how many students bring their lunch to school. This is 30% of 300. To find this value, convert the percentage to a fraction (or decimal) and multiply:

30\% \,\, \textrm{of} \,\,300 = \dfrac{3}{10} \cdot 300 = \dfrac{900}{10} = 90


Since 90 students bring their lunch to school, we can say 210 students do not bring their lunch to school. (300 - 90 = 210)

Answer:

  no feasible solutions

Step-by-step explanation:

There are so many inequalities that determining the area covered by all 5 of them is problematic. Hence, we have reversed all of them in the attached graph, so any feasible solution region would remain white. Alas, there is no such region.

This system of inequalities has <em>no feasible solution</em>.
