Answer:

Initial population is 3450 in the year 2000 and it decreases 80 every year.

Step-by-step explanation:

We are given with y=-80x+3450 where y is city's population and x is the number of years after 2000.

That is x=0 means the year 2000.

Hence y-intercept will represent the initial population which is nothing but 3450.

Since our equation slope =-80 which is negative means y is decreasing as x increases.

For x raises by 1, y decreases by 80.

That means population decreases by 80 for every year.

Answer:

The y-intercept indicates the population in the year 2000, so 3,450 people lived in the city in 2000. The negative slope indicates that the city is losing population. It loses 80 people each year.

30×·15=4.50

then subtract 30 by 4.50 to get 25.50

.0825×30=2.475

now add 2.475+25.50+30= 57.975 round to 57.98

The final answer is 36.975. The expression simplifies to 36.975 when all calculations are completed.

1. 30 + (.0825 x 30):

To calculate this part, we first multiply 0.0825 (which is 8.25% written as a decimal) by 30. This gives us:

0.0825 x 30 = 2.475

Next, we add 30 to the result:

30 + 2.475 = 32.475

2. (15% x 30):

To calculate this part, we first convert 15% to a decimal by dividing it by 100:

15% = 15/100 = 0.15

Next, we multiply 0.15 by 30:

0.15 x 30 = 4.5

Now that we have the results from both parts, we add them together:

30 + (.0825 x 30) + (15% x 30) = 30 + 2.475 + 4.5 = 36.975

The formule is about area of a circle.

[tex]\pi x^{2} = a[/tex]

We need to solve the equation for x. Where x is the radius of the circle.

In order to solve it for x, we need isolate it for x on left side.

So, first we need to get rid pi from left side.

On dividing both sides by pi, we get

[tex]\frac{\pi x^2}\pi}=\frac{a}{\pi}[/tex]

[tex]x^2=\frac{a}{\pi}[/tex]

Taking square root on both sides, we get

[tex]\sqrt{x^2}=\sqrt{\frac{a}{\pi}}[/tex]

The perimeter of an Olympic pool is 492.126 feet if the Olympic swimming pools are rectangles measuring 164.042 feet in length and 82.021 feet in width.

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

Olympic swimming pools are rectangles measuring 164.042 feet in length and 82.021 feet in width.

Perimeter = 2(length + width)

Perimeter = 2(164.042 + 82.021)

Perimeter = 2(246.063)

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the larger number is 18 more than twice the smaller. if the sum of. the two numbers are 93. let the larger number be L and the smaller number be S.

L = 18 + 2S

L + S = 93

18 + 2S + S = 93

18 + 3S = 93

3S = 93 - 18

3S = 75

S = 25

L + S = 93

L + 25 = 93

L = 93 - 25

L = 68

the top one, use the vertical line test and if their are more than two points on the vertical line when testing the points then the relation is not a function. Which tells you that the last three are not a function.

To find the x-intercept of the equation y = -13x + 3, set y to zero and solve for x to get (3/13, 0). For the y-intercept, set x to zero and solve for y, resulting in (0, 3). These intercepts are then plotted and connected to graph the equation.

Determining X and Y Intercepts

To determine the x-intercept of the linear equation y = -13x + 3, we need to set y to zero and solve for x:

0 = -13x + 3

13x = 3

x = 3/13

So, the x-intercept is (3/13, 0).

To determine the y-intercept, we set x to zero and solve for y:

y = -13(0) + 3

y = 3

Thus, the y-intercept is (0, 3).

Plotting the Intercepts

On graph paper, mark the x-intercept at (3/13, 0) and the y-intercept at (0, 3). Then use a ruler to draw a straight line that passes through these points; this line represents the equation y = -13x + 3.

The slope is the rate of change along a line. However, in this scenario, the slope is not required to plot the line since we already have the intercepts. Nonetheless, for your reference, the slope (m) in the equation y = mx + b corresponds to -13, indicating a decline of 13 units in the y-direction for each single unit increase in the x-direction.

Because the denser layers sink and the less dense layers float to the top, just like oil and water, the water is more dense than the oil, that is why the oil floats to the top and the water remains at the bottom:))

At the bottom of the density column there is liquid B with a density of 5.9 g/ml, in the middle liquid C with a density of 3.2 g/ml and in the middle liquid A with a density of 1.4 g/ml be at the top.

Explanation:

To arrange liquids A, B, and C in a density column, you must consider their respective densities, since the highest density liquid stays at the bottom and the lowest density liquid floats at the top. Liquid B has the highest density (5.9 g/ml), then liquid C with a density of 3.2 g/ml, then liquid A with the lowest density, 1.4 g/ml. Therefore, when arranging these liquids in a density column, place liquid B at the bottom, liquid C in the middle, and liquid A at the top.

Jim completed half the floor in 12 hours so it's [tex]12\times rate[/tex]= 12x 

Pete completed the other half of the floor in 10 hours so its [tex]10\times rate[/tex]=10y

12 =  1 × 2 × 2 × 3 (Composite number)

The smallest possible page number that could have been assigned will be equal to lowest common multiple of 1, 1, 2, 2 and 3.

X = 1 × 1 × 2 × 2 × 3 = 12

270 degree counter clockwise is the same as 90 degrees clockwise.

If you imagine the (x,y) axes rotating 90 clockwise, you will see that what x becomes y, and what was y becomes negative x (after the rotation).

So x-->y, and y-->-x

So the answer (c) is the correct one.

Answer:

option C

Step-by-step explanation:

the correct answer is option C

when a point (x, y )  means point lies in the first quadrant is rotated counter-clockwise to 270° means now the point will be in the fourth quadrant.

hence, in algebraic notation we interchange x by negative x

and y remains the same and their value interchanges so,

the best-suited answer will be (x, y) → (y, -x)

hence, the answer will be option C
