jolli1 [7]

Answer:

After 18 years, Zach's account balance will be $ 6,614.66.

Step-by-step explanation:

Given that Zach's parents put $ 1,500 in her bank account for college tuition at an interest rate of 8.25% compounded weekly, to determine what will be the balance after 18 years the following calculation must be performed:

1,500 x (1 + 0.0825 / 52) ^ 18x52 = X

1,500 x 1.00158653 ^ 936 = X

6,614.66 = X

Therefore, after 18 years, Zach's account balance will be $ 6,614.66.

Answer:

a) AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}

b) A∩ B = { 2, 4, 6 }

c) A-B = { 8 , 10}

Step-by-step explanation:

Step(i):-

Given that the sets

U = { 1,2,3,4,5,6,7,8,9,10}

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

B = { 1,2,3,4,5,6}

AUB = { 2,4,6,8,10} U { 1,2,3,4,5,6}

AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}

Step(ii):-

A∩ B = { 2 ,4, 6, 8,10} ∩ { 1,2,3,4,5,6} = { 2, 4, 6 }

A-B = { 2,4,6,8,10} - { 1,2,3,4,5,6} = { 8 , 10}

Final answer:-

a) AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}

b) A∩ B = { 2, 4, 6 }

c) A-B = { 8 , 10}

Answer:

given ,

$\bold{ZH = (11x - 29)}$

Also ,

$\bold{x = 19}$

substituting the value of x in the value of ZH , we get

$\bold{ZH = 11(19) - 29 }\\\bold{ ZH = 209 - 29 }\\ \bold\blue{ZH = 180}$
