Answer:

Step-by-step explanation:

If an exponential function is in the form of y = a(b)ˣ,

a = Initial quantity

b = Growth factor

x = Duration

Condition for exponential growth → b > 1

Condition for exponential decay → 0 < b < 1

Now we ca apply this condition in the given functions,

1). [tex]y=3.2(1+0.45)^{2x}[/tex]

   Here, (1 + 0.45) = 1.45 > 1

   Therefore, It's an exponential growth.

2). [tex]y=(0.85)^{3x}[/tex]

    Here, (0.85) is between 0 and 1,

    Therefore, it's an exponential decay.

3). y = (1 - 0.03)ˣ + 4

    Here, (1 - 0.03) = 0.97

    And 0 < 0.97 < 1

    Therefore, It's an exponential decay.

4). y = 0.5(1.2)ˣ + 2

    Here, 1.2 > 1

    Therefore, it's an exponential growth.

Answer:

582

Step-by-step explanation:

1200 - (1200 * (51,5%)) =  582

Answer:

582

Step-by-step explanation:

Given

Total number of students = 1200

% of male students = 51.5%

Now first calculating the number of males

= 51.5% of 1200

= 51.5 / 100 * 1200

= 618

Now Number of female students

= 1200 - 618

=582

Answer:

Step-by-step explanation:

Answer: D

Step-by-step explanation:

Expression X is monomial. Out of the 4 options, option (1) is correct.

A monomial is a mathematical expression that consists of a single term

Let's check for  each option and see whether it is a monomial or not:

1) X :

This option is a monomial, since the variable "X" itself is the only term in it. It is not associated with any exponents or coefficients.

2) [tex]3x^{0.5}[/tex]  :

Because it contains a component with an exponent of 0.5, this choice is not a monomial. Exponents on a monomial should be integers. Exponents cannot be fractions or decimals; they must be entire numbers.

3) x+1:

Because it is a binomial, this alternative is not a monomial. There are two words in it: "x" and "1," which are separated by the plus symbol. A monomial ought to include just one word.

4) 07:

07 is  not a monomial because it contains two terms, 0 and 7.

Hence, option (1) is a correct choice.

Answer:

25

Step-by-step explanation:

The line DF is

y+1 = -1/2 (x-5)

or

x+2y-3=0

The distance from E to that line is |1-8-3|/√(1^2+2^2) = 10/√5

The length of DF is √(10^2+5^2) = 5√5

So the area of DEF is 1/2 * 5√5 * 10/√5 = 25

The iota is a complex notation represented by the letter i in complex number.

iota power 2 can also be written as;

i^2

In complex number, the square root of -1 is iota. This can be expressed as;

[tex]\sqrt{-1} = i[/tex]

Take the square of both sides

[tex](\sqrt{-1})^2 = i^2\\-1 = i^2\\Rearrange\\i^2 = -1[/tex]

Hence the iota power 2 is equal to ​-1

Answer:

x = 2.98

Step-by-step explanation:

5^2x + 1 - 5^2x = 150

25x + 1 + 25x = 150

50x + 1 = 150

50x = 149

x = 2.98

5^2x + 1 - 5^2x = ?

5^2(2.98) + 1 - 5^2(2.98) = ?

25(2.98) + 1 + 25(2.98) = ?

74.5 + 1 + 74.5 = ?

149 + 1 = ?

150 = ?

The value of x is 2.98

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given an equation, 5^2x+1-5^2x=150

5^2x + 1 - 5^2x = 150

25x + 1 + 25x = 150

50x + 1 = 150

50x = 149

x = 2.98

320 is 160 percent of 200.

To determine what percent 320 is of 200, we can use the formula for calculating the percentage:

(320 / 200) x 100

First, we divide 320 by 200:

320 / 200 = 1.6

Next, we multiply the result by 100 to obtain the percentage:

1.6 x 100 = 160

Therefore, 320 is 160% of 200.

To understand this, we can think of it as comparing 320 to the whole quantity of 200. When we express 320 as a percentage of 200, it means 320 is 160% of 200, indicating that it is 1.6 times the value of 200. In other words, 320 is 60% more than 200.

The percentage calculation allows us to understand the relative proportion or ratio between two values and express it as a percentage of the whole.

Negative numbers dont have real roots, so you cannot have a square root of -1

Example: -1 x -1 does not equal -1, so this means you cannot do the same the other way

Answer:

Real numbers can be positive or negetive and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers. Imaginary numbers are numbers that cannot be quantified, like the square root of -1.

The equation first represents the possible locations of the helicopter option first is correct.

It's a two-dimensional geometry curve with two components that are both symmetric. In other words, the number of points in two-dimensional geometry that have a constant difference between them and two fixed points in the plane can be defined.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

A pair of radar stations monitor the path of a helicopter.

The path will be a hyperbola.

The center of the hyperbola = (100/2, 0) = (50, 0)

(h, k) = (50, 0)

a = 60/2 = 30

b = 100 - 60 = 40

The standard equation of the hyperbola:

[tex]\rm \dfrac{x^2-h}{a^2}-\dfrac{y^2-k}{b^2}= 1[/tex]

[tex]\rm \dfrac{x^2-50}{30^2}-\dfrac{y^2-0}{40^2}= 1[/tex]

[tex]\rm \dfrac{x^2-50}{900}-\dfrac{y^2}{1600}= 1[/tex]

Thus, the equation first represents the possible locations of the helicopter option first is correct.
