My problem is I don't know how to write an equation into exponential growth, or exponential decay.

To further explain, here is the math problem:

Rewrite y = 2(1.06)^9t in the form y = a(1+r)^t or y = a(1-r)^t to determine whether it represents exponential growth or exponential decay. Round a and r to the nearest hundredth if necessary.

I have a 2nd math problem that's just like this, but with a different equation. Can anyone help me and also teach me the way to find the answer? My notes does not cover this.

The pressure is decreasing at a rate of approximately 0.26 psi/s at t = 15 seconds.

What is pressure ?

In physics, pressure is the amount of force applied per unit area. It is a scalar quantity, which means that it has a magnitude but no direction. Pressure is typically denoted by the symbol P, and its units are commonly expressed in pascals (Pa), which is the SI unit of pressure.

Pressure can be defined as the amount of force F applied per unit area A:

P = F / A

For example, if a force of 100 newtons (N) is applied to an area of 2 square meters (m^2), then the pressure would be:

P = 100 N / 2 m^2 = 50 Pa

Pressure is an important concept in many areas of physics, including fluid dynamics, thermodynamics, and atmospheric science. It is commonly used to describe the behavior of gases and liquids under different conditions, such as changes in temperature or volume. Pressure can also be used to calculate other physical properties, such as the flow rate of a fluid or the speed of sound in a gas.

According to given condition :

The rate of change of the fuel pressure in the fuel tank of the space shuttle is given by the derivative of the function [tex]r(t) = 17e^(-0.1t)[/tex]psi per second with respect to time t. Taking the derivative of r(t), we get:

[tex]r'(t) = (-0.1) * 17e^(-0.1t)[/tex]Simplifying this expression, we get:

[tex]r'(t) = -1.7e^(-0.1t)[/tex]

To find the rate at which the pressure is decreasing at t = 15 seconds, we substitute t = 15 into the expression for r'(t):

[tex]r'(15) = -1.7e^(-0.1*15)[/tex]

r'(15) ≈ -0.26 psi/s

Therefore, the pressure is decreasing at a rate of approximately 0.26 psi/s at t = 15 seconds.

The length and breadth of the rectangle are 25.33 meters and 12.67 meters,

A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

We are given that the breadth of the rectangle is half of its length, so we can write:

B = 0.5L

We are also given that the perimeter of the rectangle is 76m. The perimeter of a rectangle is the sum of the lengths of all four sides, which in this case is:

Perimeter = 2(L + B)

Substituting the value of B from the first equation, we get:

Perimeter = 2(L + 0.5L)

Perimeter = 2(1.5L)

Perimeter = 3L

Now we can solve for L:

3L = 76

L = 25.33

So the length of the rectangle is 25.33 meters.

To find the breadth, we can substitute this value of L back into the first equation:

B = 0.5L

B = 0.5(25.33)

B = 12.67

So the breadth of the rectangle is 12.67 meters.

Therefore, the length and breadth of the rectangle are 25.33 meters and 12.67 meters, respectively.

A continuous random variable can take all values in an interval, assuming that the interval is unbounded.

This is because a continuous random variable has an infinite number of possible outcomes, and the probability density function (PDF) of a continuous random variable is defined over a range of values rather than specific values.

For example, consider the normal distribution, which is a common continuous probability distribution. The PDF of a normal distribution is a bell-shaped curve that extends from negative infinity to positive infinity.

This means that a continuous random variable following a normal distribution can take any value on the real number line, with some values being more likely than others.

However, if the interval is bounded, then it is possible for a continuous random variable to not take all values within the interval. In this case, the probability density function is zero outside of the interval, and the random variable is restricted to the range of values within the interval.

The triangle represents 1/4 of the whole trapezoid, the rhombus represents 1/2 of the whole trapezoid, and the hexagon represents 1/1 of the whole trapezoid.

Each of the shapes represent a different fraction of the whole trapezoid.

The triangle represents 1/4 of the whole trapezoid. This is because there are four triangles in the trapezoid, and each one is equal in size. Therefore, each triangle is 1/4 of the whole trapezoid. The rhombus represents 1/2 of the whole trapezoid. This is because there are two rhombuses in the trapezoid, and each one is equal in size. Therefore, each rhombus is 1/2 of the whole trapezoid.

The hexagon represents 1/1 of the whole trapezoid. This is because there is only one hexagon in the trapezoid, and it is equal in size to the whole trapezoid. Therefore, the hexagon is 1/1, or the whole trapezoid.

In conclusion, the triangle represents 1/4 of the whole trapezoid, the rhombus represents 1/2 of the whole trapezoid, and the hexagon represents 1/1 of the whole Hexagon. These fractions can be used to determine the value of each shape in relation to the whole trapezoid.

The required equation which intersects the points (12, -2) and (6, -8) in the point-slope form is y+2 = x-12.

The general form of a linear equation is y-y1=m(x-x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).

To understand more about it and see some instances, watch this video.

Both the slope-intercept form and the point-slope form can be used to write the equation of a straight line.

The slope and ANY point on the line are highlighted using the point-slope form.

Slope intercept form merely shows the slope and the y-intercept of a line.

So, we have:

m = 1

And points are (12, -2) and (6, -8)

We need to use the points: (12, -2)

Now, form the equation as follows:

y - (-2) = m (x-12)

y + 2 = 1(x-12)

y+2 = x-12

The smallest pair of 4-digit numbers such that the difference between them is 303 and their HCF is 101 are 1010 and 1313.

HCF (Highest Common Factor) of two numbers, which is the largest number that divides both numbers evenly.

Let's call the smaller of the two numbers "x". The larger number would be "x + 303".

The HCF of these two numbers must be 101, which means that 101 must be a factor of both x and x + 303.

To find the smallest possible value of x, we need to find the smallest number that is divisible by 101 and also a 4-digit number.

The smallest multiple of 101 that is a 4-digit number is

=> 101 x 10 = 1010.

Therefore, x = 1010.

The larger number would be

=> x + 303 = 1010 + 303 = 1313.

two equations are: v = u + 0.5a and (v)² = (u)² + 4a.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given, the distance traveled by an object in t = 30 minutes is 2 miles

Let "v" be the final velocity of an object,

"u" be the initial velocity of an object,

and "a" be the acceleration of an object.

From the standard velocity equation:

final velocity = initial velocity + acceleration * time.....(1)

(final velocity)² = (initial velocity)² + 2*acceleration * distance....(1)

From equation (1)

v = u + a*30 minutes

time in hours,

v = u + 0.5a

From equation (2)

(v)² = (u)² + 2*a* 2

(v)² = (u)² + 4a

A statement which best describes the function include the following: A. f(x) is a linear function because x and f(x) are both increasing.

In Mathematics, a linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate. This ultimately implies that, a linear function has the same slope and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.

Next, we would determine the slope by using the points contained in the table as follows;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (5 - 1)/(0 + 1)

Slope (m) = 4.
