If a biologist predicts that the area of the wetland will change according to the equation [tex]y = 10,000(0.65)^{x}[/tex] where;

y is the area of the wetland after x years

In order to determine the area of the wetland in 2 years based on the biologist prediction, we will substitute the value of x = 2 into the modeled equation as shown;

[tex]y = 10,000(0.65)^{2}\\y = 10,000 * 0.4225\\y = 4225[/tex]

The area of the wetland in 2 years based on the biologist prediction will be 4225 acres

The Pythagorean theorem deals with the lengths of the sides of a right triangle. ... The sum of the squares of the lengths of the legs of a right triangle ('a' and 'b' in the triangle shown below) is equal to the square of the length of the hypotenuse ('c').

Step-by-step explanation:

I guess the answer should be 177.8 cm.

The measurement of 5 feet 10 inches to centimeters​ is 175 centimeters.

Units of measurement are defines ad the definite magnitude of a physical quantity. It is used to find a number that shows the amount of something.

Here we have to convert the units of measurement feet and inches to centimeters.

We have,

1 foot = 12 inches and 1 inch = 2.5 centimeters

We have to change 5 feet 10 inches to centimeters​.

1 foot = 12 inches

⇒ 5 feet = 12 × 5 inches

              = 60 inches

So, 5 feet 10 inches = 60 inches + 10 inches

                                 = 70 inches

1 inch = 2.5 centimeters

70 inches = 70 × 2.5 centimeters

                 = 175 centimeters

Hence we got 5 feet 10 inches as 175 centimeters.

Answer:

28=256

Convert the exponential equation to a logarithmic equation using the logarithm base (2)

of the right side (256) equals the exponent (8)

.

log2(256)=8

Step-by-step explanation:

In exponential form, the base (2 in this case) is raised to the exponent (8), resulting in the value on the right side of the equation (256).

In the given equation, we have:

Log₂ 256 = 8

This equation can be read as "the logarithm base 2 of 256 equals 8."

To express it in exponential form, we need to understand that logarithms and exponentiation are inverse operations.

In other words, if we have a logarithmic equation like this, we can convert it into an exponential equation by applying the exponentiation operation.

In this case, the logarithm is base 2, so the exponential form will have a base of 2 as well.

The exponent will be the value equal to the logarithm result. Thus, we can write the exponential form as:

2⁸ = 256

In this equation, 2 is the base and 8 is the exponent.

By raising 2 to the power of 8, we get the value of 256, which is equivalent to the logarithmic expression Log₂ 256 = 8.

Hence in exponential form, the base (2 in this case) is raised to the exponent (8), resulting in the value on the right side of the equation (256).

Answer:

the correct option is number (3). It corresponds with the expression David factorised.

Step-by-step explanation:

David correctly factored the expression m² - 12m + 64, we want to check which one of the options he wrote.

(1) (m - 8)(m - 8) = (m - 8)²

= m² - 16m + 64

NOT THIS

(2) (m - 8)(m + 8) = m² - 8²

= m² - 64

NOT THIS

(3) (m - 16)(m + 4) = m² + 4m - 16m - 64

= m² - 12m - 64

THIS IS THE CORRECT OPTION AS IT CORRESPONDS WITH THE EXPRESSION DAVID FACTORISED

(4) (m + 16)(m - 4) = m² - 4m + 16m - 64

= m² + 12m - 64

The correct option is D. The graph z is representing a quadratic function.

In algebra, a polynomial function with one or more variables in which the highest-degree term is of the second degree is known as a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic.

The general form of the quadratic functions is represented as below:-

y = ax² + bx + c

Where a,b, and c are the constants x and y are variables.

The graph of the quadratic functions will be parabolic on the x-y plane.

Answer:

Step-by-step explanation:

The y intercept is the value of y when x = 0. Similarly, the x intercept is the value of x when y = 0. To find each of these, we separate the equation as shown in the attached image. After solving for x and y, we find that the y intercept is 11 and the x intercept is 22. For part e, we substitute 15 in for x. So instead of putting x in the equation, we will put 15 and solve for y. After solving, we see that y will equal 3.5. However, since we cannot have a "half apple" in the package, we see that it is not possible to have 15 apples in the package.
