9-5 skills practice solving quadratic equations by completing the square
An example of 9-5 practice question on quadratic equations by completing the square is 5x2–2x−9=0.
What are quadratic equation?This is known to be a type of algebraic expression that is based on the second degree in x. The quadratic equation often exist in a standard form such as ax2 + bx + c = 0.
To solve for 5x2–2x−9=0
Then you have to rearrange the equation into:
x2−(2/5)x−9/5=0
= x2−(2/5)x=9/5
= (x−(2/10))2−(2/5)2=9/5(here b = 2/5)
= (x−(2/10))2=46/25
Then you take the square root on both sides
= (x−(2/10))=±1.356
Therefore x=1.556 or say −1.156.

Since this cylinder has a radius of 2 inch, its volume is equal to 25.12 cubic inches.
Given the following data:
Radius of cylinder = 2 inch.Height of can = 2 inch.[tex]\pi =3.14[/tex]What is volume?In Mathematics, volume can be defined as a scalar quantity that is used to express the amount of three-dimensional (3D) space that is occupied by an object such as a cylindrical can, or enclosed by a boundary.
How to calculate the volume.Mathematically, the volume of a cylinder is given by this formula:
[tex]V = \pi r^2h[/tex]
Where:
h is the height.r is the radius.Substituting the given parameters into the formula, we have;
[tex]V = 3.14 \times 2^2 \times 2\\\\V=3.14 \times 4\times 2\\\\V=6.28 \times 4[/tex]
V = 25.12 cubic inches.

Consider the net of a triangular prism where each unit on the coordinate plane represents four feet. If a sheet of plywood measures 4 ft x 8 ft, how many sheets of plywood will a carpenter need to build the prism?
Answer:
Explanation:
2 sheets of plywood will be needed.
Step-by-step explanation:
See the attached diagram.
Each three square plywood has area 1 units by 3 units = 4 feet by 12 feet = 48 feet square. {Since each unit on the coordinate plane represents four feet}
Now, the two triangular plywood has area half of a unit square area.
So, two triangular plywood has total area = 1 unit by 1 unit = 4 feet by 4 feet = 16 feet square.
Therefore, the total area of plywood required to make the triangular prism is (48 + 16) = 64 feet square.
Now, if a sheet of plywood measures 4 ft by 8 ft i.e. 32 feet square, then the carpenter will need such sheets of plywood. (Answer)

From a point 54.0 feet from the base of a flagpole, the angle of elevation to the top of the flagpole is 68.5°. find the height of the flagpole.
The flagpole forms a right-triangle with its base and its top
The height of the flagpole is 137.1 feet
How to determine the height?To determine the height, we make use of the following tangent trigonometry ratio
[tex]\tan(68.5) = \frac{h}{54.0}[/tex]
Where:
h represents the height of the flagpole.
So, we have:
[tex]h = 54.0 * \tan(68.5)[/tex]
Evaluate
[tex]h = 137.1[/tex]
Hence, the height of the flagpole is 137.1 feet
