suppose that x and y very inversely and that y=8/3 when x =8, write a function that models the inverse variation and find y when x = 4

Answers

First find the constant k. For inverse variation, k=yx.
k=(8/3)*3=8
8=yx or y=8/x
8=4y
y=2

a bottle contains 12 red marbles and 8 blue marbles. A marble is chosen at random and not replaced. Then a second marble is chosen at random. Determine the probability that the two marbles are not the same color.

Answers

$P(A)= (12)/(20) \cdot (8)/(19) + (8)/(20) \cdot (12)/(19)= (12\cdot8)/(20\cdot19) \cdot2=(12\cdot4)/(5\cdot19)= (48)/(95)$

Find the first,fourth, and eighth terms of the sequence. A(n)=-5*2^n-1

Answers

Answer: $A(1)=-5$

$A(4)=-40$

$A(8)=-640$

Step-by-step explanation:

Given sequence : $A(n)=-5*2^(n-1)$

To find the first term, we need to put n=1 in the above sequence , we get

$A(1)=-5*2^(1-1)=-5*2^0=-5$

To find the fourth term, we need to put n=4, we get

$A(4)=-5*2^(4-1)=-5*2^3=-5*8=-40$

To find the eighth term, we need to put n=8, we get

$A(8)=-5*2^(8-1)=-5*2^7=-5*128=-640$

Answer:

$A(1)=-5*2^1-1=-11$

$A(1)=-5*2^4-1=-81$

$A(1)=-5*2^8-1=-1281$

Step-by-step explanation:

Given : $A(n)=-5*2^n-1$

To find : $A(1), A(4), A(18)$

Solution:

Put n=1, $A(1)=-5*2^1-1$

$A(1)=-10-1=-11$

Put n=4, $A(1)=-5*2^4-1$

$A(1)=-80-1=-81$

Put n=8, $A(1)=-5*2^8-1=$

$A(1)=-1280-1=-1281$

What is the surface area of the prism? A. 138 yd2 B. 192 yd2 C. 264 yd2 D. 272 yd2

Answers

To find the surface area of this rectangularprism, we have to figure out the sum of all of the areas. Here is a formula that we can use to do this. We can substitute the given values into the formula. The length of the prism is 9 inches, the width is 3 inches and the height is 5 inches.

The general formula for the lateral surface area of a right prism is L . S . A . = p h where p represents the perimeter of the base and h represents the height of the prism. Example 1: Find the lateral surface areaof a triangular prism with bases edges 3 inches, 4 inches and 5 inches and altitude 8 inches.
