Well, you know that the area of the rectangle is 12 square feet. And you know one of the numbers multiplied to get 12 is 5, so divide 12 by 5. You would get 2.4 as the other number needed.
In this case, 5 feet is the width and 2.4 feet is the length.
Step-by-step explanation:
For a
Let the another angle be x then
x + 51° = 90° {being complementary angles }
x = 90° - 51°
x = 39°
For b
Let the another angle be x then
x + 113° = 180° {being supplementary angles }
x = 180° - 113°
x = 67°
Usually, the function of a parabola is y=ax^2+bx+c. With your three given points, which I don't know, plug in your x's and y's to come up with three quadratic equations. Using those equations, you use algebra to find out what a, b, and c equal. Once you have a numerical answer, insert them in the usual quadratic function to have your answer.

The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let p represent the bacteria population in thousand after d days.
Since each day, the bacteria population grows by a factor of 2, hence:
Hence, d = log₂p represents a logarithmic function
The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.
