A rectangular goat pasture has dimensions represented by the expressions y – 4 and 4y^2-3y+5 .Find the area of the pasture.

Nataly_w [17]

Given that the goat pasture is rectangular with the dimensions given by:
Length=(y-4) and Width=(4y^2-3y+5)
Thus the area of the pasture will be given:
Area=length*width
Area=(4y^2-3y+5)(y-4)
Area=y(4y^2-3y+5)-4(4y^2-3y+5)
Area=4y^3-19y^2+17y-20

Show that (2, 1) is a solution of the system of equations. x + 3y = 5, y = –x + 3 Substitute (2, 1) into x + 3y = 5 to get . Sim

Natalka [10]

I am not sure if I understand the question that clearly but if what I think is correct is that you need to prove that 2 and 1 are a system of equations for the following equations so this is how you do that:

With the coordinates (2,1) 2 will be x and 1 will be y because when dealing with coordinates (x,y) is how they are set up.

Next you substitute into the equations and solve:

(2) + 3(1) = 5 and 1 = -(2)+3

So now you find if the equations are true

2 + 3 = 5 so (2,1) is a solution for this equation

-2 + 3 = 1 so (2,1) is also a solution for this equation

So in conclusion (2,1) is a solution of the system of equations

Hope this helps :)

Which list shows fraction that ALWAYS result in a terminating decimal for values of n > 0? A) 1/11, 1/121, 1/1331 . . . , 1/1

Alla [95]

Answer:

B) 1/10, 1/100, 1/1000 . . . , 1/10n

Step-by-step explanation:

Comparing all the options given:

A) 1/11, 1/121, 1/1331 . . . , 1/11n

Finding the decimal of the first term,

1/11 = 0.0909090 (never ending decimal place)

B) 1/10, 1/100, 1/1000 . . . , 1/10n

Finding the decimal of the first term,

1/10 = 0.01 (ended decimal place)

C) 1/6, 1/36, 1/126 . . . , 1/6n

Finding the decimal of the first term,

1/6 = 0.16666667 (never ending decimal place)

D) 1/3, 1/9, 1/27 . . . , 1/3n

Finding the decimal of the first term,

1/3 = 0.33333333 (never ending decimal place)

At the beginning of every year, Molly deposits $200 in a savings account that offers an interest rate of 20%, compounded annuall

Lena [83]

Hi, thank you for posting your question here at Brainly. To solve this problem, use this formula: F = P(1+i)^n, where F is the future worth, P is the present worth, i is the annual interest and n is the number of years. Substituting the values,

F = $200 (1+0.2)^3
F = $345.6

The answer is $345.6.
