The height of the cedars when they were planted by André, found using the formulas for arithmetic progression is 1.32 meters

An arithmetic progression is a number sequence that consists of numbers that have a constant or common difference between consecutive term of the sequence.

The year André planted the cedar hedge tree = 15 years ago

The present height of the hedge = 3 meters = 300 cm

The average rate at which the cedars grew = 12 cm per year

The height of the cedar hedge when André initially planted the them can be found by representing the situation using an arithmetic progression formula or as follows;

The nth term of an arithmetic progression, aₙ, can be found using the formula; aₙ = a₁ + (n - 1)·d

Where;

a₁ = The initial height of the tree

d = The amount the tree grows each year = 12 cm

n = The number of years ago, the tree was planted

When n = 15, we get;

a₁₅ = 3 meters = 300 cm

Therefore;

300 = a₁ + (15 - 1) × 12

a₁ = 300 - (15 - 1) × 12 = 132

In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range.

The group of all outputs of a function is called its range. for example: Let's have a look at the function f: A→ B, where f(x) = 2x and A and B each represent a "collection of natural numbers. The domain in this case is A, and the co-domain is B. The range then appears as the function's output. so Set of all even natural numbers is the range.

A relation between a number of set of inputs with only one output corresponding to each of the input is called function.

Example:

Y = 2x

1. First, we have to write the function y=f(x) and then solve the equation for x and taking out equation of form x=g(y).

Suppose we have a function y=x2+1 and we have to find it range so,

we have to solve it for x to get

x=√y-1.

2. Now we have to find the domain of g(y), and this is simply the range of function f(x).

For our example,

y−1≥0, so [1,∞) is the range of f(x)=x2+1.

3. If we can't solve equation for x, then we can try it by drawing the graph of the function and find its range.

2,857 = a*100 + b*1

There are multiple solutions for this, we can use b to cover the ones and the tens, so:

Answer:

75%

Step-by-step explanation:

First, you subtract 200 from 350 to get the difference, which is 150.

Then, you do 150 divided by 200 since 200 is the starting number and it is increasing by 150.

150/200 = 0.75

To convert the decimal into a fraction multiply by 100.

0.75*100 = 75

The formula for slope-intercept form is: y = mx + b

    m = the slope of the line

    b = the y-coordinate of the y-intercept, (0,b)

In this case, the slope is 3, since you go up 3 and to the right 1 to get from the point at (1,1) to the point at (2,4).  3/1 = 3

The line crosses the y-axis at (0,-2), so your b-value is -2.

The equation is y = 3x - 2.

In general, lines that increase (go uphill) from left-to-right have a positive slope.  Lines that decrease (go downhill) from left-to-right have a negative slope.

The speed of the wind is 100 miles per hour.

Speed is the ratio of distance traveled and the time taken to travel the distance.

Given that, the twin-engine aircraft can fly 960 miles from city A to city B in 3 hours with the wind.

Let the speed of the wind and the aircraft be w and p respectively.

The net speed with the wind is:

w + p

Since the distance between the cities is 960 miles and the aircraft covers it in 3 hours with the wind, the net speed with the wind is:

w + p = 960/3

w + p = 320

p = 320 - w

Similarly, the net speed against the wind is:

p - w = 960/8

p - w = 120

Substitute p = 320 - w into the above equation:

320 - w -w = 120

2w = 320-120

w = 100

A graph is symmetric with respect to the y-axis if for every point (a, b) on the graph, there is also a point (-a, b) on the graph.

Linear functions are not symmetric with respect to the y-axis.

Quadratic functions are symmetric with respect to the y-axis if the y-axis is their axis of symmetry, so when the variable x is squared.

Cubic functions are not symmetric about the y-axis.

Square root functions are not symmetric about the y-axis.

There are two quadratic functions with x² in the given answer options.

Test to see if they are symmetric with respect to the y-axis.

Test for symmetry

To determine if a graph is symmetric with respect to the y-axis, replace all the x's with (−x).  If the resultant expression is equivalent to the original expression, the graph is symmetric with respect to the y-axis.

Given function:

[tex]y=-6x^2[/tex]

Replace x with (-x):

[tex]\implies y=-6(-x)^2[/tex]

[tex]\implies y=-6x^2[/tex]

Therefore, as the function is equal to the original function, this function is symmetric with respect to the y-axis.

Given function:

[tex]y=4x^2-2[/tex]

Replace y with (-y) and x with (-x):

[tex]\implies y=4(-x)^2-2[/tex]

[tex]\implies y=4x^2-2[/tex]

Therefore, as the function is equal to the original function, this function is symmetric with respect to the y-axis.
