Answer: $1,423.014

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

A = P (1 - r) t  

Where:  

A = Future value of investment

P = Principal Amount  

r = Annual Nominal Interest Rate decrease (decimal form)  

t= years

Replacing with the values given  

A = 1500 ( 1- 2.6/100)^2

A = 1500 ( 1-0.026)^2

A= 1500 ( 0.974)^2

A = $1,423.014

Feel free to ask for more if needed or if you did not understand something.

Answer: M(2) = $1500*(1 - 0.026)^2 = $1423.01

Step-by-step explanation:

Initially in the acount there is $1500

You lose a 2.6% (or 0.026 in decimal form) per year, so after the first year you have:

M = $1500 - 0.026*$1500 = $1461

After other year, you lose oter 2.6%

M = $1461 - 0.026*$1461 = $1423.01

The equation can be writen as:

M(t) = $1500*(1 - 0.026)^t

Where t is the number of years, you can use t = 2 and get:

M(2) = $1500*(1 - 0.026)^2 = $1423.01

Romashka [77]

Answer:

11,880 different ways.

Step-by-step explanation:

We have been given that from a pool of 12 candidates, the offices of president, vice-president, secretary, and treasurer will be filled. We are asked to find the number of ways in which the offices can be filled.

We will use permutations for solve our given problem.

^nP_r=\frac{n!}{(n-r)!}, where,

n = Number of total items,  

r = Items being chosen at a time.        

For our given scenario n=12 and r=4.

^{12}P_4=\frac{12!}{(12-4)!}

^{12}P_4=\frac{12!}{8!}

^{12}P_4=\frac{12*11*10*9*8!}{8!}

^{12}P_4=12*11*10*9

^{12}P_4=11,880

Therefore, offices can be filled in 11,880 different ways.

Len [333]

Answer:

288 cubic cm

Step-by-step explanation:

Volume of the pyramid = 1/3 * base area * height

Base area = 12 * 12

Base area - 144 sq. cm

Height = 6cm

Volume of the pyramid = 144 * 6/3

Volume of the pyramid = 144 * 2

Volume of the pyramid  = 288 cubic cm

What is the surface area of this right triangular prism ? round your answer to the nearest tenth.​
velikii [3]

Answer:

78 m^2 Unless I got some of the measurements wrong, kinda hard to see them.

Step-by-step explanation:

The surface area will be the sum of the area of each face.  so lets see, there is the base (in this orientation) which is a 8x3 rectangle it looks like.

then two trianglular sides with both having a base of 8 and height of 3

then two "roof" pieceswhich are rectangles again, one side of 3 and the other 5.

Now we add each face up.

rectangular base = 3x8 = 24

2 triangular sides = 2(.5*8*3) = 24

2 rectangular roof pieces = 2(5*3) = 30

Now add it all up

24+24+30 = 78
