The base is reducing at a rate of 3.4cm per min.
Answer:
Step-by-step explanation:
A) Use the slope formula to find the slope m.
m=4/13
B) Use the point-slope formula, y−y1=m(x−x1) to find the equation of the line.
y=4/13x+198/13
C) Write in slope-intercept form, y=mx+b.
y=4/13x+198/13
The equation x^2 - 6x + 9 is a perfect square and when factored out it becomes C. ) It is a perfect square (x - 3)^2
We are given equations as

Firstly, we will write in slope intercept form of line
y=mx+b

Subtract both sides by 4x


now, we can divide both sides by a

we can find slope
so, we get

we are given second equation as

Firstly, we will write in slope intercept form of line
y=mx+b
divide both sides by a

we can find slope

we are given both lines are perpendicular
so, the multiplication of their slopes must be -1

we can plug values

now, we can solve for a

Multiply both sides by a


now, we can solve for a
we get

Answer:
- 10.7 liters of paint required
Step-by-step explanation:
Dimensions of the room
- 7.7 m by 14.8 m with the height of 2.4 m
Find the surface area of the 4 walls
- A = Ph = 2(l + w)h = 2(7.7 + 14.8)*2.4 = 108 m²
Convert the area to ft²
- 108 m² = 108*10.7639 ft² = 1162.5012 ft²
Find the amount of paint required
- 1162.5012/410 = 2.84 gal (rounded)
Covert the volume to liters
- 2.84 gal = 2.84*3.76 l = 10.7 l (rounded)
