Using the graph of g we get (a) value of function g at x=0 is 5
(b) [tex]\lim_{x \to \00} g(x)[/tex] or limit of g(x) at x=0 does not exist
(c) value of function g at x=1 is 4
(d) [tex]\lim_{x \to \11} g(x)[/tex] or limit of g(x) at x=1 is 4
What is limit of a function how can limit be interpreted using graph of that function?
Limit : Limit is the value that a function output approaches as the input approaches to a certain value.
For any function g(x) ,[tex]\lim_{x \to \22} g(x)[/tex] means that the value g(x) approaches as the x approaches to 2 .
From any graph we can easily see that to what value g(x)=y on the curve is approaching when the x is approaching to some value on x axis and if the graph is breaking on the value where x is approaching then the limit does not exist for that value of x.
For given graph
We can see value of value of function g at x=0 is 5 and value of function g at x=1 is 4
As the graph is breaking on x=0 into two functions then [tex]\lim_{x \to \00} g(x)[/tex] or limit of g(x) at x=0 does not exist
As the graph is not breaking at x=1 or we can say that graph of g(x)is approaching to 4 as x approaches to 1 then [tex]\lim_{x \to \11} g(x)[/tex] or limit of g(x) at x=1 is equal to g(1) that is 4

During a clearance sale at a sporting goods store,skateboards were marked down 30%.on saturday,additiobal 25% was taken off already reduced prices of skateborads originally cost 119.50,what was the final price ater all dicounts had been taken?round to the nearest cent
The final price after all discounts is $62.74.
What is the final price?A discount is when the price of an item is decreased. An item becomes cheaper when a discount is applied.
Percentage is the fraction of an amount expressed as an amount out of 100. Percentage is a measure of frequency. The sign used to represent percentage is %.
Price of the skateboard after the first discount = (1 - discount) x initial price
(1 - 0.30) x 119.50
0.70 x 119.50 = $83.65
Price of the skateboard after the second discount = (1 - discount) x discounted price
(1 - 0.25) x $83.65
0.75 x $83.65 = $62.74.

In order to scuba dive safely, divers must be aware that the water
pressure in the ocean is a function of depth. The water pressure increases by
0.445 pounds per square inch (psi) for each foot of depth. The pressure at the
surface is 14.7 psi. Write a function to represent water pressure. What is the
value of the function for an input of 50, and what does it represent?
The value of the function at an input of 50 will be 36.95.
How to calculate the value?Since the pressure at the surface is 14.7 psi, a function to represent water pressure will be:
= 14.7 + (0.445 × p)
where p is the increase in pressure for each foot
= 14.7 + 0.445p
Therefore when the input is 50, the amount will be:
= 14.7 + 0.445p
= 14.7 + 0.445(50)
= 14.7 + 22.25
= 36.95

Kudi and Ladi share 20 oranges in the ratio 2 is to 3 how many oranges has Ladi
Answer:
12 oranges
Step-by-step explanation:
The ratio is K/L where K = Kudi's oranges and L = Ludi's oranges
K/L = 2/3
To find the number of oranges that Kudi has, divide the numerator by the sum of numerator and denominator.Then multiply by total number of oranges
For Ladi, divide the denominator by the sum of numerator and denominator. Then multiply by total number of oranges
[tex]K = 20\cdot \dfrac{2}{2+3} = 20 \cdot \dfrac{2}{5} = 8 \; \mathrm {oranges}\\\\L = 20\cdot \dfrac{3}{2+3} = 20 \cdot \dfrac{3}{5} = 12 \; \mathrm {oranges}[/tex]
So answer is Ladi has 12 oranges
Is the following relation a function? Justify your answer. Two circles are shown, one labeled x and the other labeled y. The x circle contains the numbers 6, negative 1, and 4. The y circle contains the numbers 2, negative 1, and 3. Arrows map numbers from x to numbers from y. There are arrows going from 6 to 3, from negative 1 to 2, from negative 1 to negative 1, and from 4 to 3. No, because there is an input value with more than one output value No, because there is an output value with more than one input value Yes, because each input value has only one output value Yes, because each output value has only one input value
each input is mapped into only one output, then this relation is a function.
The correct option is "Yes, because each input value has only one output value"
Is the relation a function?
A relation maps elements from a set (called the domain, which is the set of the inputs) into elements from another set (called the range, which is the set of the outputs). Such that these mappings generate coordinate pairs (x, y) or (input, output)
A relation is a function only if all the elements in the domain are mapped into only one value in the range.
On the given relation, we have the coordinate pairs:
(6, 3)
(1, 2)
(-1, -1)
(4, 3)
So we can see that each input is mapped into only one output, then this relation is a function.

Define Area?Area is typically thought of as a specific instance of volume for two-dimensional regions. By applying axioms, one can define area as the relationship between a set of real numbers and a collection of particular plane figures.
Area is a mathematical concept that describes the size of a region on a planar or curved surface. The area of an open surface or the border of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
According to the given values;
The area of Rhode Island = 43.07 billion square feet.
The area of Colorado = 2.9045 trillion square feet.
43.07 billion =43,070,000,000
2.945 trillion =2,9045,000,000,00
Now we have to find how many times as great is the area of Colorado than the area of Rhode Island.
For this ,we divide area of Colorado by area of Rhode Island.
=2,9045,000,000,00/43,070,000,000

Answer:

Step-by-step explanation:
Let's solve your system by substitution.
4x+2y=10;3x+5y=11
Step: Solve4x+2y=10for x:
4x+2y=10
4x+2y+−2y=10+−2y(Add -2y to both sides)
4x=−2y+10
4x/4 = −2y+10/4
(Divide both sides by 4)
x= −1/2y+5/2
Step: Substitute −1/2y+5\2 for x in3x+5y=11:
3x+5y=11
3(−1/2y+5/2)+5y=11
7/2y+15/2=11(Simplify both sides of the equation)
7/2y+15/2+−15/2=11+/−152
(Add (-15)/2 to both sides)
7/2y=7/2
7/2y/7/2 = 7/2/7/2
(Divide both sides by 7/2)
y=1
Step: Substitute1for y in x= −1/2y+5/2:
x=−1/2y+5/2
x=−1/2(1)+5/2

The point of intersection for the function is (2, 2)
Considering to the line passing through the points (0,6) and (3,0) to be f(x).Therefore the slope intercept of the function is
m = 0-6/3-0 = -2
So, the functions F(x) in the slope-intercept form f(x)= -2x+6 ......1
interchanging the variable x to y and y to x
=> x =-2y + 6
=> 2y = -x + 6
=> y= -0.5x + 3
let f⁻¹(x)= y
f⁻¹(x) =-0.5x+3 ......2
Solving the equation 1 and 2, we get
=> -0.5x + 3 = -2x + 6
=> 2x - 0.5x = 6 - 3
