Junior is saving money in his piggy bank. He starts with and adds two pennies each day. Create an table and a graph for the function for which represents the number of days since Junior started saving money and y represents the total money he has saved
The required expression for the Junior started saving money and y represents the total money he has saved is y =2x.
Given that,
Junior is saving money in his piggy bank. He starts with and adds two pennies each day.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Let the number of days, junior saved money be x and the total amount of money he saved be y.
He starts with and adds two pennies each day. which implies,
On day 1 he saved 2 pennies, the next day i.e. day 2 is saved 4 pence and so on and on day x he saved a total of 2x pennies in his piggy bank. Results,
y = 2x
Thus, the required expression for the Junior started saving money and y represents the total money he has saved is y =2x.

Hey there! I'm happy to help!
Here's how to find the distance between any two points.
Subtract the x values.
5-(-1)=5+1=6
Square that.
6²=36
Subtract the y values.
0-4=-4
Square that.
-4²=16
Add the two numbers you got.
36+16=52
And square root it.
√52≈7.2.

Step-by-step explanation:
In Argentina, a cow on a ranch is expected to need an average of 4200 m2
of grassland for food.
What size does a ranch need to be to feed 4500 cows?
Give your answer in hectares.
The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.
And we are asked to find the total area of their grazing but in hectares. So, we can write:
[tex]1 \: cow = 4200 \: {m}^{2} [/tex]
Then, for 4500 cows:
[tex]4500 \: cows = 4200 \: {m}^{2} \times 4500[/tex]
[tex]4500 \: cows = 18900000 \: m {}^{2} [/tex]
We know that, 1 hectares = 10000 m² = 10⁴ m²
Then let the area of the field be x in hectares:
[tex]1 \: hectare = 10000 \: {m}^{2} [/tex]
[tex]x \: hectare = 18900000 \: {m}^{2} [/tex]
Then, putting them in proportion, We will get:
[tex]x = \dfrac{18900000}{10000} hectares[/tex]
[tex]x = \boxed{ 1890 \: hectares}[/tex]
So, the total area in hectares = 1890 hectares.
And we are done !!

Since we know sin^2 θ = (sin θ)^2
In our problem,
sinθ = 2/sqrt(3)
Let's plug this value into our expression above.
(2/sqrt(3))^2
Let's square both terms individually.
2^2 = 4
(sqrt(3))^2 = 3
