Answer:
Step-by-step explanation:
we can do like
8y-7x+2y² -x-5
= 2y^2 + 8y - 8x - 5 ( we know that - 5 = 8 - 13)
= 2( y^2 + 4y + 4) - 8x - 13
= 2 (y+2)^2 -8x - 13
I do not know that you wrongly type but here is the answer.
2. 1.25
4. 1.75
3. 1.2555
1. 1.2
Ones: All digits in the ones are the same
Tenths: 7 is greater than two.
Pool and deck = 60 ft by 50 ft
First question: Area of the deck including the deck
A = 60*50 = 3000 ft^2
Average cost = $4,560
Discount offered = 20%
Second question: Cost after discount
This is a question of proportionality. That is;
$4,560 ------------ 100%
Actual cost ------ (100-20)% -----80%
Then,
Actual cost after discount = (4,560*80)/100 = $3,648
Area of the pool is 750 ft^2 and one side is 30 ft.
Third question: Length of the other side
Area = L*W, if Length, L = 30 ft, Width, W = ??
750 = 30*W
W = 750/30 = 25 ft.
Then, the other side is 25 ft long.
Cost per 10 ft length of fence costs $25.50
Fourth question: Total cost of fencing
Circumference = 2(L+W) = 2(60+50) = 220 ft
Number of 10 ft sections = Circumference/10 = 220/10 = 22 sections
Total cost = number of sections*Cost per section = 22*25.50 = $561
Answer:
Step-by-step explanation:
The Bessel function or order zero of the first kind may be defined by the solution - to Bessel's differential equation - which is a finite value at the origin X=0 for positive or negative whole numbers (integers) or positive alpha (α) values.
