c they are equil
Step-by-step explanation:
Answer:
A) 56.60 cubic units
Step-by-step explanation:
A = πr²/3(h₁ + h₂)
= 3.14ₓ(2.6)²(5 + 3)/3
= 3.14ₓ6.76ₓ8/3
= 169.8112/3
= 56.60 cubic units
Answer:
The value of cos 0 = - 2 sqrt(85) / 85 = - 0.216930458
Step-by-step explanation:
cos 0 = ?
Point on the terminal side of 0 : (-2,9)=(x,y)→x=-2, y=9
cos 0 = x/r
r=sqrt(x^2+y^2)
Replacing the known values:
r=sqrt( (-2)^2+(9)^2)
r=sqrt(4+81)
r=sqrt(85)
cos 0 = x/r
cos 0 = -2 / sqrt(85) = -2/9.219544457 = -0.216930458
Rationalizing:
cos 0 = -[2 / sqrt(85)] [sqrt(85) / sqrt(85)]
cos 0 = - 2 sqrt(85) / [sqrt(85)]^2
cos 0 = - 2 sqrt(85) / 85
Answer:
The definite integral expressing the total quantity of oil, 'V', which leaks out of the tanker in the first hour is given as follows;
Step-by-step explanation:
From the question, we have;
The rate at which oil leaks out of the tanker, r = f(t)
The unit of the oil leak = Liters per minute
The unit of t = Minutes
Therefore, we have;
The definite integral expressing the total quantity, 'V', of oil which leaks out of the tanker in the first hour is given as follows;
Therefore, we have;
4x-y= -36
Distribute the 4: y-12=4x+24
Add 12 to both sides: y=4x+36
Move the y to the other side: 0=4x-y+36
Subtract 36 from both sides: 4x-y= -36
