Answer:

10 = 6

11) = 11

Step-by-step explanation:

1)

(a-5)- (2b-9) +c = \\ (6 - 5) - (2(3) - 9) + 2 \\ (1) - (6 - 9) + 2 \\ (1) - ( - 3) + 2 \\ 1--3+2 \\ 1+3+2 \\ 4+2 \\  = 6

2)

( {b}^{2}  -  2b + 6) + 3b - 7 \\ ( {3}^{2}  - 2(3) + 6) + 3(3) - 7 \\ (9 -6  +  6) + 9 - 7 \\ (9) + 2 \\  = 11

Find the average value of the function f(x, y, z) = 5x2z 5y2z over the region enclosed by the paraboloid z = 9 − x2 − y2 and the
Katyanochek1 [597]
The paraboloid meets the x-y plane when x²+y²=9. A circle of radius 3, centre origin. 

<span>Use cylindrical coordinates (r,θ,z) so paraboloid becomes z = 9−r² and f = 5r²z. </span>

<span>If F is the mean of f over the region R then F ∫ (R)dV = ∫ (R)fdV </span>

<span>∫ (R)dV = ∫∫∫ [θ=0,2π, r=0,3, z=0,9−r²] rdrdθdz </span>

<span>= ∫∫ [θ=0,2π, r=0,3] r(9−r²)drdθ = ∫ [θ=0,2π] { (9/2)3² − (1/4)3⁴} dθ = 81π/2 </span>


<span>∫ (R)fdV = ∫∫∫ [θ=0,2π, r=0,3, z=0,9−r²] 5r²z.rdrdθdz </span>

<span>= 5∫∫ [θ=0,2π, r=0,3] ½r³{ (9−r²)² − 0 } drdθ </span>

<span>= (5/2)∫∫ [θ=0,2π, r=0,3] { 81r³ − 18r⁵ + r⁷} drdθ </span>

<span>= (5/2)∫ [θ=0,2π] { (81/4)3⁴− (3)3⁶+ (1/8)3⁸} dθ = 10935π/8 </span>

<span>∴ F = 10935π/8 ÷ 81π/2 = 135/4</span>

Find the difference. 8.25 - (-1.9) <br> A.8.44 <br> B.6.35 <br> C.10.15 <br> D.-6.35
quester [9]

Answer:

C. 10.15

Step-by-step explanation:

If you left 8.25 and changed the minus sign to a addition sign and the -1.9 to just 1.9 and then add 8.25 + 1.9 together you will then get 10.15 a way to remember this is “leave, change, change,” you leave the first number and change the subtraction and negative number sign. :)
