Answer:
1. It has two points in common with the x-axis.
2. The vertex in relation to the x-axis is at
Step-by-step explanation:
The points that the equation has in common with the x-axis are the points of intersection of the parabola with the x-axis.
To find them, substitute y=0 and solve for "x":
Use the Quadratic formula:
It has two points in common with the x-axis.
To find the vertex in relation to the x-axis, use the formula:
Substituting values, you get:
Answer:
Step-by-step explanation:
Please consider the attached image as the given square.
We are asked to express the shaded area as a fraction, a decimal, and a percent of the whole.
We can see that in our figure there are 100 squares as there are 10 rows and each row contains 10 squares.
We can also see that there are 81 shaded squares out of 100 squares, so we can represent it as a fraction as:
To convert the shaded area into decimal, we need to divide 81 by 100.
To convert the shaded area into percent, we need to multiply 0.81 by 100.
Answer:
The base and height of the garden are 4.60 ft and 5.60 ft.
Step-by-step explanation:
The area of the garden is, <em>A</em> = 24 ft².
The base height of the garden are:
base (<em>b</em>) = 6x - 4
height (<em>h</em>) = x + 3
Compute the value of <em>x</em> as follows:
The last equation is a quadratic equation.
Compute the roots of the quadratic equation as follows:
The value of base and height are:
Thus, the base and height of the garden are 4.60 ft and 5.60 ft.
