Answer:

Statements: 6, 1, 8, 3, 4, 7

Step-by-step explanation:

y = 3x/(8 + x)

x = 3y/(8 + y)

x(8 + y) = 3y

8x + xy = 3y

8x = 3y - xy

8x = y(3 - x)

y = 8x/(3 - x)

y = f^-(x) = 8x/(3 - x)

If U = {x: X € N, 1 < × < 15)

Inessa05 [86]

Answer:

Step-by-step explanation:

Given:

U = {x: X € N, 1 < × < 15) = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}

A = {2,4,6,8,10,12,14}

B = {3,6,9,12,15}

C = {5,10,15}

(a) Verify A(BnB)=(AUB)(AUB)

A U (B n B)

= {2,4,6,8,10,12,14} U ( {3,6,9,12,15} n {3,6,9,12,15} )

= {2,4,6,8,10,12,14} U {3,6,9,12,15}

= {2,3,4,6,8,9,10,12,14,15}

( A U B) n (A U B)

= {2,3,4,6,8,9,10,12,14,15} n {2,3,4,6,8,9,10,12,14,15}

= {2,3,4,6,8,9,10,12,14,15}

Therefore

A U (B n B) = ( A U B) n (A U B)

verifies

(b) Verify An(BUC)=(AnB)u(AnC)

A n ( B U C)

= {2,4,6,8,10,12,14} n ( {3,6,9,12,15} U {5,10,15} )

= {2,4,6,8,10,12,14} n {3,5,6,9,10,12,15}

= {6,10,12}

( A n B ) U ( A n C )

= ( {2,4,6,8,10,12,14} n {3,6,9,12,15} ) U ( {2,4,6,8,10,12,14} n {5,10,15} )

= {6,12} U {10}

= {6,10,12}

Therefore

A n ( B U C) = ( A n B ) U ( A n C )

verifies

AU(BUC)

= {2,4,6,8,10,12,14}U{3,6,9,12,15}U{5,10,15}

= {2,3,4,5,6,8,9,10,12,14,15}

(AUB)U(AUC)

= ({2,4,6,8,10,12,14}{3,6,9,12,15})U({2,4,6,8,10,12,14}U{5,10,15})

= {2,3,4,6,8,9,10,12,14,15}U{2,4,5,6,8,10,12,14,15}

= {2,3,4,5,6,8,9,10,12,14,15}

Therefore

AU(BUC)=(AUB)U(AUC)

verifies

Write and solve a problem involving money that can be solved with a mu ltiplication equation

Lelu [443]

Mary is saving up money to go on a trip. This month, she saved three times as muchmoney as she saved last month. Last month, she saved $24.00. How much money did Mary save this month?As much as tells you that you have a comparison.Three times is the multiplier.$24.00 is the amount in the first set.How much money did Mary save this month? is the question you are being asked. To solve, multiply $24.00 x 3. $24.00 x 3 = $72.00.It’s important to clearly show that you understand what your answer means. Instead of just writing $72.00, write:Mary saved $72.00 this month.Whenever you finish a math problem of any kind, always go back to the original problem. Think: “What is the question I am being asked?” Make sure that your final answer is a reasonable answer for the question you are being asked.I was asked, “How much money did Mary save this month?” My answer is: Mary saved $72.00 this month.My answer is reasonable because it tells how much money Mary saved this month. I multiplied a whole number by a whole number, so the amount of money Mary saved this month should be more than she saved last month. Seventy-Two is more than 24 . My answer makes sense.

Answer:

X is the hypotenuse and using 60°

Cos theta =adjacent/ hypotenuse

where 5 is your adjacent cos 60° is equals to 5/X

X= 5/Cos 60° = 5/0.5 = 10... B
