Okay, here we have this:
Considering the provided information, we are going to calculate how many bags of fertilizer should be purchased to cover a rectangular lawn that is 29400 square feet, so we obtain the following:
Number of bags=Total space / Space per bag
Number of bags=29400ft² / 2000ft²
Number of bags=14.7
Number of bags≈15 bags of fertilizer.
Finally we obtain that rounded to the nearest unit, 15 bags of fertilizer are needed.

surface area of the net pyramid is 125 in²
Explanation:Surface area of a net pyamid is calculated as:
[tex]S\mathrm{}A\text{ = area of base + }\frac{1}{2}perimeter\text{ of base }\times slant\text{ height}[/tex]side of the base = 5 in
Area of the base = area of square
Area of the base = (side of the base)² = 5²
Area of base = 25 in²
Perimeter of base = perimeter of square
Perimeter of base = 4(side of the base) = 4(5)
Perimeter of base = 20 in
slant height = 10 in
Inserting the values into the formula for surface area:
[tex]\begin{gathered} S.A\text{ = }25\text{ + }\frac{1}{2}(20)(10) \\ S.A\text{ = }25\text{ + 100} \\ S\mathrm{}A\text{ = 125 in}^{2} \end{gathered}[/tex]I have a question where I need to graph a hyperbola equation and all I am given is the equation Picture included
Given
The equation of the hyperbola is:
[tex]\frac{y^2}{9}\text{ -x}^2\text{ = 1}[/tex]We can see that this is a vertical hyperbola since y is positive.
The general equation of a vertical hyperbola is:
[tex]\begin{gathered} \frac{(y-k)^2}{a^2}\text{ -}\frac{(x\text{ -h})^2}{b^2}=\text{ 1} \\ Where\text{ }(h,k)\text{ is the center} \end{gathered}[/tex]The steps to graph a hyperbola are:
1. Determine if it is horizontal or vertical. Find the center point, a, and b.
2. Graph the center point.
3. Use the a value to find the two vertices.
4. Use the b value to draw the guiding box and asymptotes.
5. Draw the hyperbola.
Step 1: This hyperbola is vertical
center point = (0,0)
Step 2: The values of a and b
[tex]\begin{gathered} a^2=\text{ 9} \\ a\text{ = 3} \\ b^2\text{ = 1} \\ b\text{ = 1} \end{gathered}[/tex]Step 3: Draw the guiding box:
Step 4: Draw the asymptotes
The asymptotes are diagonal lines through the corners of the box
Step 5: Finally, we draw in our hyperbola. Each half starts at the vertex and continues towards the asymptotes but never actually reaches them.
Step 6:
The center point, guiding box, and asymptotes are not technically part of the answer, so a clean version of the graph would look like this:

The mapping diagram represents a relation where x represents the independent variable and y represents the dependent variable.
A mapping diagram with one circle labeled x-values containing values negative 4, negative 2, 0, 1, and 3 and another circle labeled y values containing values negative 5, negative 4, negative 3, negative 2, and negative 1 and arrows from negative 4 to negative 5, negative 2 to negative 3, 0 to negative 4, 0 to negative 2, 1 to negative 3, and 3 to negative 1.
Is the relation a function? Explain.
No, because for each input there is not exactly one output
No, because for each output there is not exactly one input
Yes, because for each input there is exactly one output
Yes, because for each output there is exactly one input
Answer:
This relation is not a function. For each input, there is not exactly one output.
The relationship in the given diagram is not a function, because for each input there is not exactly one output. So Option A is correct
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
Values of x and values of y
In given diagram,
for x = 0,
there are two values of y, -4 and -2
but according to definition of y, it should give only one value
Hence, it is not a function

Step 1: Concept
The rule for 2: 2 can divide any number that ends with even numbers 0, 2, 4, 6, 8.
The rule for 3: For a number to be divide by 3, its sum must be divided by 3.
The rule for 4: For a number to be divide by 4, the last two digits must be divided by 4
The rule for 5: For a number to be divided by 5, it must end with 0 or 5.
The rule for 6: A number is divisible by 6 if it is divisible by 2 and 3.
The rule for 8: A number is divisible by 8 if its last three digits are divisible by 8.

How to find the area of a composite figure?The rose garden is formed by joining a rectangle and a semicircle. The rectangle is 26 ft long and 18 ft wide.
The area of the garden can be found as follows:
area of the garden = area of the rectangle + area of the semi circle
Therefore
area of the garden = lw + 1 / 2πr²
l = 26 ft
w = 18 ft
r = 18 / 2 = 9 ft
area of the garden = 26 × 18 + 1 / 2 × 3.14 × 9²
area of the garden = 468 + 254.34 / 2

This month the mail carrier delivered mail on the morning route 10 times and on the afternoon route 15 times, for a total distance traveled of 123.75 miles. What is the distance of the morning route in miles?
The distance of the morning route is 5.25 miles.
What is the distance of the morning route?The first step is to form a system of equations that would represent the information in the question:
16m + 12a = 141 equation 1
10m + 15a = 123.75 equation 2
The equations would be solved using the elimination method:
Multiply equation 1 by 5 and equation 2 by 4
80m + 60a = 705 equation 3
40m + 60a = 495 equation 4
Subtract equation 4 from equation 3:

To be able to determine which table would correctly graph the equation y = 3x, let's one pair of data in the table and substitute it to the equation. The data that satisfies the equation is therefore the one that would correctly graph the equation.
We get,
A.) x = 0 and y = 2
y = 3x
2 = 3(0)
2 = 0
Therefore, this table will not correctly graph the equation.
B.) x = 0 and y = 4
y = 3x
