Y=52(0.42)^x identify if it's growth or decay and determine the percentage rate of increase or decrease

Mathematics
1 answer:
Shkiper50 [21]3 years ago
4 0

Answer:

58%

Step-by-step explanation:

Given the exponential relation :

Y=52(0.42)^x

Since 0.42 is less than 1, then we can infer that the expression is a Decay function ;

. General form of a exponential function :

y = A(1 - r)^x ; r = Decay rate

Comparing the general equation with the equation given ;

The percentage rate of decrease is obtained thus :

1 - r = 0.42

1 - 0.42 = r

r = 0.58

Rate = 0.58 * 100%

Rate = 58%

The sum of 2 even numbers is 234 . Write and equation and solve for the numbers
Maurinko [17]
2 even numbers....x and x + 2

x + x + 2 = 234
2x + 2 = 234
2x = 234 - 2
2x = 232
x = 232/2
x = 116 <===

x + 2 = 116 + 2 = 118 <==

Are my answers correct? Precalculus!!
SVETLANKA909090 [29]

Answer:

Unfortunately, your answer is not right.

Step-by-step explanation:

The functions whose graphs do not have asymptotes are the power and the root.

The power function has no asymptote, its domain and rank are all the real.

To verify that the power function does not have an asymptote, let us make the following analysis:

The function y = x ^ n , when x approaches infinity, where does y tend? Of course it tends to infinity as well, therefore it has no horizontal asymptotes (and neither vertical nor oblique)

With respect to the function y= \frac{1}{x} we ​​can verify that if it has asymptote horizontal in y = 0. Since when x approaches infinity the function is closer to the value 0.

For example: 1/2 = 0.5;   1/1000 = 0.001;    1/100000 = 0.00001 and so on. As "x" grows "y" approaches zero

Also, when x approaches 0, the function approaches infinity, in other words, when x tends to 0 y tends to infinity. For example: 1 / 0.5 = 2; 1 / 0.1 = 10; 1 / 0.01 = 100 and so on. This means that the function also has an asymptote at x = 0

What is 575% written as a mixed number?
pav-90 [236]

<u><em>Answer:</em></u>

575% as a mixed number is 5\frac{3}{4}

<u><em>Explanation:</em></u>

575% is equivalent to \frac{575}{100} which is equal to 5.75

5.75 = 5 + 0.75

0.75 can be written as \frac{75}{100}. This value can be simplified by dividing both the numerator and the denominator by 25. This would give us \frac{3}{4}

<u>Back to our number:</u>

5.75 = 5 + 0.75 = 5 + \frac{75}{100} = 5 + \frac{3}{4} = 5\frac{3}{4}

Hope this helps :)
