What is the vertex of the graph of y = x2 + 4x?<br> (–2, –12)<br> (–2, –8)<br> (–2, –6)<br> (–2, –4)
SCORPION-xisa [38]

Answer: The vertex of the parabola (quadratic function) is (-2,-4)

Fourth option: (-2,-4)


Solution:

y=x^2+4x

y=ax^2+bx+c; a=1, b=4, c=0

Vertex: V=(h,k)

h=-b/(2a)

h=-4/(2(1))

h=-4/2

h=-2

y=x^2+4x

k=y=h^2+4h

k=(-2)^2+4(-2)

k=4-8

k=-4

Vertex: V=(h,k)

Vertex: V=( -2, -4)

A barrel was 2/3 full of water. After 60 liters were used from the barrel, it was 5/12 full. how much water does the barrel hold
Andrews [41]

Answer: 240 liters

Step-by-step explanation: This means, we start off with (2/3)x liters of water. Then we subtract off 60 of them to get to 5/12 full, meaning we have (5/12)x liters left.

Chris used 45 meters of fencing to enclose a circular garden. What is the approximate radius of the garden,rounded to the neares
kobusy [5.1K]
The length of the fencing corresponds to the length of the perimeter of the garden:
p=45 m
We also know that the perimeter of a circle is given by:
p=2 \pi r
where r is the radius of the circle.

Putting together the two equations, we have
2 \pi r = 45
from which we can find r, the radius of the garden:
r= \frac{45}{2 \pi}= \frac{45}{2 \cdot 3.14}=7.17 m
