slope = change in y/ change in x
select two points on the line
(-4,4)
(0,1)
= (4-1)/(-4-0)
= -3/4
I think u do 3•5 then divide by 110
- 81 %
Step-by-step explanation:
To find the percentage change;
([Current – Initial] / Initial) * 100
([14 - 75] / 75) * 100
(-61 / 75) * 100
(-0.81333) * 100
= - 81.3333 %
To the nearest percentage;
= - 81 %

Answer:
b = 4.6 ft
h = 2.3 ft
Step-by-step explanation:
The volume of the tank is given by:

Where 'b' is the length of the each side of the square base, and 'h' is the height of the tank.
The surface area can be written as:

The value of b for which the derivate of the expression above is zero is the value that yields the minimum surface area:

The value of h is then:

Rounded to the nearest tenth, the dimensions are b = 4.6 ft and h = 2.3 ft.
Answer:
Step-by-step explanation:
a)
- 1.5x² + 6x + * =
- 1.5(x² + 4x + *) =
- 1.5(x² + 2*2x + 4) =
- 1.5(x + 2)²
- * = 1.5*2² = 6
b)
- 2x² - 5x + * =
- 2(x² - 2.5x + *) =
- 2(x² - 2*1.25x + 1.25²)=
- 2(x - 1.25)²
- * = 2*(1.25)² = 3.125 or 25/8
