The expression does not represent next year's population is 0.991. The correct option is A.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the population of a city decreases by 0.9% per year. The expression for the population depreciation is,

Population = ( 100% - 0.9%)P

Population = (1 - 0.009)P

Population = 0.991P

Hence, the expression not representing the depreciation is 0.991.

When convert it into rectangular form we get x=-1/2 and y=0.

To convert a point in polar coordinates (r, θ) to rectangular coordinates (x, y), you can use the following formulas:

[tex]x = r * cos(θ) \\y = r * sin(θ)[/tex]

Where r is the distance from the origin to the point, and θ is the angle in radians between the positive x-axis and the line connecting the point to the origin.

Alternatively, you can also convert from rectangular to polar coordinates using the following formulas:

[tex]r = sqrt(x^2 + y^2)\\θ = atan2(y, x)[/tex]

Where x, y are the rectangular coordinates and atan2 is a function that computes the angle of a point in a cartesian plane.

In general, it's worth noting that the polar coordinates are often used in some physics and engineering problems, while the rectangular coordinates are often used in computer graphics, analytic geometry and other fields.

The angle of 1's inverse tangent is 45°. This is the outcome of translating to polar coordinates in the form (r,theta).

To convert it into rectangle equation we have

[tex]x=rcos(theta)\\y=rsin(theta)\\r=1\\theta= 3*pi/2\\x= cos(3*pi/2)\\x= -1/2\\y=sin(3*pi/2)\\y=0[/tex]

Answer:

C= 54.O4

.................

The rate of change of surface area is 524.02 square kilometers per minutes.

The total space occupied by a three-dimensional square prism is called surface area.

Given, the decreasing rate of the base side with respect to time, ds/dt = 7 km/min

the increasing rate of height with respect to time, dh/dt = 10 km/min

At a time, t, base side, s = 4 km

and height, h = 9 km

we need to determine the rate of change of surface area with respect to time, d A/dt

from the differentiation chain rule, d A/ dt = d A /dt × ds /ds

                                                        d A /dt = d A/ ds × ds /dt ... equation 1

we know that the surface area for prism, A = 2s² + 4sh

if we differentiate with respect to s then we find d A /ds

  d/ds (A) = d/ ds (2s² + 4sh)

d A /ds = 4s + 4h +4s dh/ds ......  equation 2

now dh /ds = dh /ds × dt /dt [ using differentiation chain rule]

dh/ds = dh/ dt× dt/ds

d h/ ds = dh/dt × 1/ ds/dt

it stated earlier that dh/ dt = 10 and ds /dt = 7

dh / ds = 10/7

putting this value in equation 2, we get

d A /ds = 4s +4h + 4s ×10/7

as we know at time t, s= 4 and h = 9

d A /ds = 4 × 4 + 4 ×9 +4×4 ×10 /7

d A /ds = 74.86

putting the value  d A /ds in equation 1, we get

d A /dt = d A /ds × ds/ dt

d A/ dt = 74.86 × 7

d A /dt = 524.02 km² / min

hence, the rate of change of surface area = 524.02 square kilometers per minutes

The amount of rain required would be 2.5 inches.

What is the addition?

Addition is a mathematical operation that represents the process of combining two or more numbers together. The result of this operation is called the sum. The addition operation is often represented using the symbol "+", and it can be used to add any two or more numbers together.

To beat the record by one-tenth of an inch, an additional 0.1 inches of rain must fall.

Currently, the average amount of rain per day is 12 inches / 5 days = 2.4 inches per day.

So, the amount of rain that must fall on Friday to beat the record by one-tenth of an inch is 2.4 inches + 0.1 inches = 2.5 inches

Hence, the amount of rain required would be 2.5 inches.

Answer:

Hakims car travels 600 feet in 20 seconds. Andres mortar cycle travels 300 feet in 12 seconds. Which is faster, the car or the motorcycle?

The car is faster

Find the unit rates

The car is going 30 feet in 1 second(600 divide by 20 = 30)

The motorcycle is gonig 25 feet in 1 second(300 divide by 12 = 25)

Compare the unit rates

30 > 25

Step-by-step explanation:

Answer:

Hakim's car is faster.

Step-by-step explanation:

Hakim's car takes 20 seconds to go 600 feet. Andre's motorcycle takes 24 seconds to go 600 feet.

So for Hakim, the unit rate are 30 feet per second because 600/20 = 30

For Andre, the unit rate is 25 feet per second because 600/24 = 25

Hakim's car goes faster because 30 is greater than 25.

On solving the provided question, we can say that - here the value of exponential equation is 648/1296 = 0.5

Exponentiation, often known as "b raised to the nth power," is a mathematical operation denoted by the symbol bn that involves two numbers: a base number, b, and an exponent, or power, n. Exponents show how many times a number has been multiplied by itself. As an illustration, 2-3 (written as 23) denotes: 2 x 2 x 2 = 8. 23 is not equivalent to 2 + 3 = 6. Recall that an integer raised to the power of one equals itself. A approach to express huge numbers as powers is through the use of exponents. Exponent, then, is the quantity that indicates how many times a number has been multiplied by itself. As an illustration, 6 is multiplied by 4 to provide 6 x 6 x 6 x 6. It may be expressed as 64. 4 is where

So, the equation is

Answer: The answer to your question is the letter B. May want to assess it before answering.

Answer:

He would need to save $22 dollars each week to pay for the bike in 7 weeks.

Step-by-step explanation:

We can figure out how many he has saved up already by multiplying the number of weeks (12) by how much he saved each week ($8) which equals $96. Now we have to subtract $96 from $250 which equals $154. Now we need divide this amount by the remaining weeks until he wants to purchase his bike (7), so 154/7 which equals $22.

So he needs to pay 22 dollars each week to pay off the bike in seven weeks

Answer:

$6.30

Step-by-step explanation:

Alright, so, to find the unit rate (how much 1 pound of corn would cost) you would divide $15.60 by 12 which would get you $1.30.

Cost of 1 pound of corn = $1.30

So the unit rate = $1.30

Now that you know the unit rate, or how much 1 pound would cost, you can find out how much 5 pounds would cost:

$1.30 x 5 = $6.50

Steps:

1. $15.60/12 = $1.30

2. $1.30 x 5 = $6.50

Five pounds of corn costs $6.50 at a unit rate of $1.30.

The effect of subtracting 2 from the input on the graph of the function is a translation of 2 units to the right.

For any function f(x), we define a horizontal translation of N units as:

g(x) = f(x + N)

And what this does, is translate the graph N units horizontally.

if N > 0, then the translation is to the left.

if N < 0, then the translation is to the right.

Here we want to subtract 2 from the input, so we will get:

f(x - 2)
