6. Let f be the function defined by f(x)=1x2+9.
(a) Evaluate the improper integral ∫∞3f(x) dx, or show that the integral diverges.
(b) Determine whether the series ∑n=3∞f(n) converges or diverges. State the conditions of the test used for determining convergence or divergence.
(c) Determine whether the series ∑n=1∞(−1)n(en⋅f(n))=∑n=1∞(−1)n(n2+9)en converges absolutely, converges conditionally, or diverges.

a seed company sells two grades of grass seed. And hundred pound bag of a mixture of rye and Bluegrass sells for $255, and a hundred pound bag of Bluegrass sales for $348. How many bags of each are sold in the week when the receipts for 18 bags are $5334?
Answer:
8 bags of rye & bluegrass mix
10 bags of bluegrass
Step-by-step explanation:
RB = bags of rye & bluegrass mix
B = bags of bluegrass
348B + 255RB = 5334
RB+B = 18 then RB = 18-B
substitute for RB
348B + 255(18-B) = 5334
348B + 4590 - 255B = 5334
reduce
93B = 744
B = 8
RB = 10

Answer:
x=5
Step-by-step explanation:
first multiply both sides by 12 and by 5 to get rid of your fractions
5(5x-1) = 12(x+5)
expand the brackets
25x-5=12x+60
minus 12x from both sides
13x-5=60
add 5 to both sides
13x=65
divide both sides by 13
x=5
hope that helps

Which expressions are polynomials? Select the two correct answers. (2 points)
A. x4+2y2+z−w2
B. x−3+x√
C. x−3−x+1
D. −4x8
9514 1404 393
Answer:
A, D
Step-by-step explanation:
Only expressions that are constant, or with variables to positive integer powers are polynomials.
A square root is a fractional power. (eliminates B)
-3 is not a positive power. (eliminates C)
The remaining choices are A and D.
A. x^4 +2y^2 +z -2^2 . . . . is a polynomial
D. -4x^8 . . . . is a polynomial

[tex] {x}^{2} - 4 \div x - 2[/tex]
Step-by-step explanation:
[tex]\dfrac{x^2-4}{x-2}[/tex]
Apply identity a²-b² = (a-b)(a+b)
So, it will be
[tex]\dfrac{(x-2)(x+2)}{x-2}[/tex]
Where x-2 gets cancelled from numerator and denominator.
Hence, x+2 is the answer.
Hope it helps :)

Answer:
x = 4 and y = 1
Step-by-step explanation:
The given equations are :
2x+5y = 13 ...(1)
3x-2y = 10 ...(2)
We can use elimination method to solve the given equations.
Multiply equation (1) by 3 and equation (2) by 2.
6x+15y=39 ...(3)
6x-4y=20 ...(4)
Subtract equation (3) from (4).
6x-4y-(6x+15y) = 20-39
6x-4y-6x-15y = -19
-19y=-19
y = 1
Put the value of y in equation (1).
2x+5y = 13
2x+5=13
2x=8
x = 4
So, the solution of the given equations are x = 4 and y = 1.
