A rectangle has an area of 99 square in. What is the length of the long side?
OLga [1]

Answer:

The longer length is either 99, 33 or 11 inches

Step-by-step explanation:

Given

Area = 99

Required

The length of the longer side

Area of a rectangle is:

Area = Length * Width

List out all possible products that give 99 [Assume the dimension are whole numbers]

Length * Width = 99 * 1 = 99

Length * Width = 33 * 3 = 99

Length * Width = 11 * 9 = 99

List out the longer factors

L = \{99, 33, 11\}

<em>Hence, the longer length is either 99, 33 or 11 inches</em>

Give a possible formula for the function below. Let A = (-1, 32) and B = (1, 8). (Note: Use the general exponential function.)
skelet666 [1.2K]
The question ask to find and compute the possible formula for the function below where as A = (-1,32) and B= (1,8).  In my own calculation and further computation about the problem and also following the rule of general exponential function, the formula would be y = a*(b^x). I hope this would help

<h3>What is geometrical figure?</h3>

Geometrical shapes are the shapes that depict the shapes of various items. Various figures have two dimensions, while others have three. Only the x and y axes are used for two-dimensional figures, whereas the x, y, and z axes are used for three-dimensional shapes.

<h3>According to the given information:</h3>

Given,

Area = 11000m²

Radius = .10m/h

We know the area of the circle:

Area = πr²

The relation between parameter:

Area = πr²

11000 = 3.14 * (0.10t)²

Dividing both side by 3.14

11000/3.14 = (3.14 * (0.10t)²)/3.14

by solving this we get:

(.10t)² = 3503.184

.10t = 59.187

dividing both side by 0.10

t  = 59.187/.10

t =  591.877

t = 592

hours did it take for oil to cover the area  = 592
