Write the equation of the quadratic function in standard form represented by the graph.
Answers
Answer:
y = x^2 +6x+8
Step-by-step explanation:
First find the zeros, -4 ,-2
y =a (x - -4) (x - -2)
y = a(x+4)(x+2)
Then it is multiplied by a constant so pick a point on the curve and solve for the constant
We will use (0,8)
8 = a(0+4)(0+2)
8 = a(8)
a =1
y = (x+4)(x+2)
Writing in standard form
FOIL
y = x^2 +2x+4x+8
y = x^2 +6x+8

what is the area of this figure?
Answers
Answer:
Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.

Find the area of the figure.

8 cm
Answers
Answer:
The area is [tex]88cm^2[/tex]
Step-by-step explanation:
The formula for the area of a triangle is : [tex]\frac{base*height}{2}[/tex]
To work this out you would first need to work out the area of the square. You can do this by multiplying the length of 8 by the width of 8, this gives you 64. This is because the formula for working out the area is length multiplied by the width.
The next step is to work out the area of a triangle. You can do this by first multiplying the base of 6 by the height of 8, this gives you 48.
The next step is to divide 48 by 2, this gives you 24. this is because the formula is the same for a square, and that a triangle is half of a square with the same dimensions.
The final step is to Add the area of the square which is 64 by the area of the triangle which is 24, this gives you [tex]88cm^2[/tex].
1) Multiply 8 by 8.
[tex]8*8=64cm^2[/tex]
2) Multiply 6 by 8.
[tex]6*8=48cm[/tex]
3) Divide 48 by 2.
[tex]48/2=24cm^2[/tex]
4) Add 64 and 24.
[tex]64+24=88cm^2[/tex]
Workers need to know the area of a park to determine how much grass seed to order. A worker drew a sketch of the park to find its area. Which is the area of the park?
Answers
The area of the figure is 1465 square m because the figure consists of squares and trapezoids.
What is a square?It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.
We have a figure shown in the picture that represents a sketch of the park.
Workers need to know the area of a park to determine how much grass seed to order.
The figure consists of squares and trapezoids.
The trapezoid can be defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.
The area of the figure = area of the square + area of the trapezoid
The area of the figure = 10×10 + (38 + 40)35/2
The area of the figure = 100 + (78×35)/2
The area of the figure = 100 + 1365
The area of the figure = 1465 square m
Thus, the area of the figure is 1465 square m because the figure consists of squares and trapezoids.

True or False data from frequency table can be used to make a scaled bar graph
Answers
Yes, it is true that data from the frequency table can be used to make a scaled bar graph.
What is a bar graph?A bar graph is a graphical depiction of information, amounts, or numbers using bars or strips. They are utilized to contrast and compare various data types, frequencies, or other measurements of several categories of data.
The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values. Frequency tables or charts are used to represent frequency distributions.
so bar graphs can be made by frequency table because, To compare the frequency of one category or attribute with that of another, a bar graph is employed. The frequency for each category or attribute is displayed in the bar's height (if vertical) or length (if horizontal).
Hence it is true to make a bar graph from a frequency table.
