Answer:
lateral surface area of the cone =49π
Step-by-step explanation:
y= x/4
dx/dy = 4
Given x range as from 0 ≤ x ≤ 7 ⇒ x ranges between (a,b)
a= x/4 = 0/4 = 0
b = x/4= 7/4
lateral surface area of the cone
=32π * 49/(16 *2)
=49π
Answer:
x = -5/2 or 3/2
Step-by-step explanation:
If we let z = 2x+3, the equation can be written ...
... z² -4z -12 = 0
and can be factored as
... (z -6)(z +2) = 0
Then the solutions are z = -2, z = 6.
This means the values of x that are solutions are ...
... 2x +3 = {-2, 6} . . . . work with both possibilities at once
... 2x = {-5, 3} . . . . . . . subtract 3
... x = {-5/2, 3/2} . . . . .divide by 2
Actually, distributive property isn't needed to combine this. You can simply subtract 7 from 13 which will give you 6. The solution is 6c.
Answer:
30 square units
Step-by-step explanation:
because the distance from point a to b is 6 units and the distance from point b to c is 5 units then to find the area u multiply 5*6 u get 30
