Answer:

Step-by-step explanation:

Check for each vector

u=\\4u=\\||4u||=\sqrt{12^2+8^2}\\=\sqrt{208} \\=14.42

Hence this is the required vector.

u=\\4u=\\||4u||=\sqrt{4^2+16^2}=16.49

u=\\4u=\\||4u||=\sqrt{8^2+8^2}=11.31

u=\\4u=\\||4u||=\sqrt{8^2+16^2}=17.889

Hence required vector =

BSE is square.

Let side be s

  • s=90ft

Diagonal be d

\\ \tt\longmapsto s=\dfrac{d}{\sqrt{2}}

\\ \tt\longmapsto d=s\sqrt{2}

\\ \tt\longmapsto d=90\sqrt{2}

\\ \tt\longmapsto d=127ft

Ephemeral services corporation (esco) knows that nine other companies besides esco are bidding for a $900,000 government contrac
EastWind [94]

Answer:

c. $100,000

Step-by-step explanation:

Calculation of the expected net profit of Ephemeral services corporation

Since we are been told that 9 other companies besides esco are as well bidding for the $900,000 government contract, it means we have to find the expected net profit by dividing 1 by 9×$900,000 .Thus ESCO can only expect to cover its sunk cost.

Hence ,

E(X) = (1/9) × $900,000

E(X)=0.111111111×$900,000

E(X)= $100,000

Therefore the expected net profit would be $100,000

What is total 14.56 plus tip 15% plus tax7%.
Alexandra [31]
Hi,
The total amount is 17.91608
How I got my answer:
100 + tip%/100 * 14.56 = amount with tips
100 + 15/100 * 14.56
115/100 * 14.56
1.15 * 14.56 = 16.744
100 + tax%/100 * amount with tips = total amount
100 + 7/100 * 16.744 = total amount
107/100 * 16.744 
1.07 * 16.744
17.91608 = total amount
Hope this Helps you.

You start at (7, 2). You move up 5 units. Where do you end?
tankabanditka [31]

Answer:

(7,7)

Step-by-step explanation:

Because going up would be moving along the y-axis, then you would add 5 to the Y value which was 2 so therefore, if you move up 5 you'll be at (7,7).:)
