What is the definition of exponential decay

klio [65]

Answer:

Kindly check explanation

Step-by-step explanation:

When we have an exponential function, this means that a certain item of sum changes by a fixed percentage rate over a certain period of time.

Decay in Mathematics means reduction. Hence, Applying this knowledge to the concept of exponential Decay, we could say exponential deacy means a reduction process an object or thin undergoes as it decreases by a fixed percentage rate over a certain period of time.

Mathematically, exponential Decay is expressed as :

y = a(1-b)^x

Where, a = Initial amount

(1 - b) = Decay factor ; where b = decay rate.

x = period.

There are 6 squares and 2 circles. What is the simplest ratio of circles to total shapes?

Sunny_sXe [5.5K]

Add to find the total number of shapes.

6 + 2 = 8

Circles to total amount of shapes -> 2:8

Divide 2 to both sides.

2/2:8/2

1:4

Therefore, the answer is 1:4

Best of Luck!

Consider the quadratic function f(x) = x2 – 5x + 12. Which statements are true about the function and its graph? Select three op

Rashid [163]

Answer:

I will assume the equation is supposed to be f(x) = <u>x^2</u> – 5x + 12 since it is said to be a quadratic equation.

Step-by-step explanation:

<u>See attached graph.</u>

The value of f(–10) = 82 <u><em>False</em></u>

f(-10) = (-10)^2 - 5*(-10) + 12

f(-10) = (100) +50 + 12

f(-10) = 162

The graph of the function is a parabola. <u><em>True</em></u>

The graph of the function opens down. <u><em>False</em></u>

The graph contains the point (20, –8). <u><em>False</em></u>

The graph contains the point (0, 0). <u><em>False</em></u>

Bill reads 1/5 of a book on Monday he reads 2/3 of the book on Tuesday if he finishes reading the book on Wednesday or fraction

ratelena [41]

Answer:

$\frac{2}{15}$

Step-by-step explanation:

We have been given that Bill reads 1/5 of a book on Monday he reads 2/3 of the book on Tuesday.

Let x be the part of book that Bill read on Wednesday. We can find x by equating the sum of parts of book read on each day by 1.

$\frac{1}{5}+\frac{2}{3}+x=1$

First of all we will find a common denominator.

$\frac{1\times 3}{5\times 3}+\frac{2\times 5}{3\times 5}+x=1$

$\frac{3}{15}+\frac{10}{15}+x=1$

$\frac{3+10}{15}+x=1$

$\frac{13}{15}+x=1$

$x=1-\frac{13}{15}$

$x=\frac{15-13}{15}$

$x=\frac{2}{15}$

Therefore, Bill read $\frac{2}{15}$ of the book on Wednesday.
