Each number after the decimal goes in this order:
tenth
hundredth
thousandth
1. Looks like it's under the second number after the decimal. This would be the hundredth. The number after it is less than 5 so you would round down and keep the number 7, which makes 0.67
2. Being under the first number after the decimal, it would be the tenth. The number 8 is higher than 5 so you need to round the 2 up to three, making it 4.3
Do you think you could solve the rest or would you like more examples?

How many different ways can you choose 5 books from a shelf containing 12 books? Type a numerical answer in the space provided.
yanalaym [24]
There are 792 different ways of choosing 5 books from a shelf containing 12 books. This problem can be solved using the combination formula of mathematics. The combination formula of mathematics is a number of way of selecting thing from a collection and the formula stated as n(n-1)...(n-k+1)/k(k-1)...1 (Calculation: 12*11*10*9*8/5*4*3*2*1 = 95040/120 = 792)<span>.</span>

1. What is the sum of the two vectors (-1,-4) and (3,5)?
mash [69]

What is the sum of the two vectors (-1,-4) and (3,5)

to find the sum we add x component with x and y with y

So

(-1+3) , ( -4+5) = (2,1)

Hence option B is the correct option


2. Evaluate the following expression: -1(5,-1) + 2(1,1)

-1(5,-1) + 2(1,1) = (-5 , 1) + (2,2)

= ( -3 , 3)

Second option is the correct


3. Evaluate the following expression (1,4) -5(1,1)

(1,4) -5(1,1)

= (1,4) (-5,-5)

= (1-5 , 4-5)

= (-4,-1)


4. Let v=(8,-4) and w=(-4,2). Which of the following is true?

as we can see

(8,-4) = -2(-4,2)

v= -2w

and also the Y component of w is 2


5. Which of the following vectors are orthogonal to (-1,3)?

The orthogonal vector will be (3,1) as the dot product is zero

(-1,3).(3,1) = (-3+3) = 0

Hence Option third is the correct one
