Mathematics

Answer:

No

Step-by-step explanation:

Step 1: Write equation

8u - 1 = 6u

Step 2: Solve for <em>u</em>

  1. Subtract 6u on both sides: 2u - 1 = 0
  2. Add 1 to both sides: 2u = 1
  3. Divide both sides by 2: u = 1/2

∴ u = -1/2 is NOT a solution.

2. A father offers three portions of his crop land to his daughter for a corn maze. All
Tamiku [17]

If the daughter does not want more than 2,250,000 square feet of the corn maze, hence she will choose all the portions

<h3>Circumference and area of circles</h3>

The formula for calculating the area of circle is expressed as;

A  = πr²

r is the radius of the circle

If r = 875ft

A = 3.14(875)²

A = 2,404,062.5squar feet

For the diameter = 1715feet

r = 1715/2

A = 3.14(1715/2)²

A =2,308,861.625 square feet

For the third portion has a 5305 feet circumference;

5305 = 2(3.14)r

r = 844.74ft

A = 3.14(844.74)^2

A = 2,240,686.70

If the daughter does not want more than 2,250,000 square feet of the corn maze, hence she will choose all the portions

Use the graph of the function to find the domain and range of f.
Alik [6]
The domain is the x-values u insert to get corresponding y-values. In other words, the domain is the boundaries for which u can enter x valies. In this graph, we can see that the function continues infinitely upwards, not vertical shifting a bit to the sides. This means that the domain is all x belonging to the set R, since for any x value, we will get a corresponding point on the graph. For the range, it is simply the range of the y-values. From the graph, teh range is -4
