<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal 
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them 

we know from above that u.v = 120 

|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29

so we know: 

theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>

Round to the nearest whole number 35, 2, 7, 33, 25, 70, 75, 40, 42, 12, 15, 7, 44, 20, 25, 3, 65, 62

The numbers 35, 2, 7, 33, 25, 70, 75, 40, 42, 12, 15, 7, 44, 20, 25, 3, 65, and 62 are all whole numbers.

  • All natural numbers and 0 are considered whole numbers. They are real numbers without fractions, decimals, or negative integers.
  • Rounding a number implies simplifying it while retaining its value close to what it was. The end output is less precise but more usable.
  • In a given base, a round number is an integer that ends with one or more "0s." So, 590 is more rounded than 592 but less rounded than 600. A round number is frequently understood in both technical and casual language to stand for a value or values close to the nominal value represented.

What is the equation of the line that passes through the points (-1,3) and (1,11)?
marta [7]

Answer:

y=4x+7

Step-by-step explanation:

You can find the slope of the line by using the formula of change and y over change in x. ∆y/∆x OR (y2-y1)/(x2-x1)

11-3=8

1--1=2

8/2=4

Let's plug in a y value 3.

3=4*-1+b

b=7

Once you found b rewrite your equation in slope intercept form.

y=4x+7

You can check this equation by plugging in the unused coordinate (1,11) and find it balances.

A new operation is defined by a△b=a^2-b/b-a^2. 4△3.
dmitriy555 [2]

As the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1

As per the question statement, we are given a new mathematical operation a△b=a^2-b/b-a^2 and we are supposed to find the value of 4△3 using the same operation.

Given, a△b=a^2-b/b-a^2

now 4△3 = (4^2-3) / (3-4^2)  

4△3 = (16-3) / (3-16)        

4△3 = 13 / -13  

4△3 = -1

Hence, as the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1.

  • Mathematical operation: An operator in mathematics is often a mapping or function that transforms components of one space into elements of another.
