Answer:
847.8 sq meters
Step-by-step explanation:
Formula:
A= 2πrh + 2πr^2
A= 2(3.14)(9)(6) + 2(3.14)9^2
A= 339.12 + 508.68
A= 847.8
Answer:
b. 4x^2 -7x +5
Step-by-step explanation:
When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...
(7x^2 -5x +4) - (3x^2 +2x -1)
= (7 -3)x^2 +(-5 -2)x +(4 -(-1))
= 4x^2 -7x +5 . . . . . matches B
It is true the relationship is proportional.
hope this helps!!
Most of the information's required for finding the answer is already given in the question.
Height of the fly = 12 feet
Width of the fly = 16 feet
Now we can find the length of the poles using Pythagoras theorem.
Length of the poles = square root [(12)^2 + (8)^2]
= square root (144 + 64)
= square root (208)
= 14.4 feet
From the above deduction, we can conclude that the height of the poles needed to be 14.4 feet. I hope the answer has helped you.
(g + f)(x)
g(x) + f(x)
x - 1 + x^2 + 4
x^2 + x + 3
(g - h)(x)
g(x) - h(x)
3x + 1 - (2x - 2)
3x + 1 - 2x + 2
x + 3
