A two digit number exceeds the sum of the digits of that number by 18. If the digits at the unit's place is double the digit in
snow_tiger [21]

Answer:

The number is 24

Step-by-step explanation:

Let the two digits number be ab

In real terms, this is 10a + b

So, we have that the sum of the digits subtracted from 10a + b is 18

Mathematically, we have this as;

10a + b - (a + b) = 18

10a + b - a - b = 18

9a = 18

a = 18/9

a = 2

We are also told that the digit at the units place b is double the digit at the ten’s place a

That means b = 2a

b = 2 * 2 = 4

Write the direction cosines of the vector -21-5k​
AlekseyPX

Answer:

a=-2î+j-5k

|a| = √(−2)² +1² + (−5)²

a = √√4+1+25

a = √30

Thus, direction cosines of a are

(- 2/(sqrt(30)), 1/(sqrt(30)), - 5/(sqrt(30)))

Given the graph of f(x), find each of the following:
Y_Kistochka [10]

The value of the function at x = -1, 0, 1, 2, and 3 will be -4, 3, 2, -1, and 0, respectively.

<h3>What is a function?</h3>

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

From the graph of f(x), then the value of the function at x = -1, 0, 1, 2, and 3 will be given as,

x             f(x)                        Feedback

-1             -4               Point is in the fourth quadrant

0              3                      Point is in the y-axis

1               2               Point is in the first quadrant

2             -1               Point is in the second quadrant

3              0                      Point is in the x-axis

More about the function link is given below.
