Answer:
Step-by-step explanation:
Volume = mass * density
<u>Substitute values and calculate:</u>
- V = 618.7 * 2.7 = 1670.49 mL
<h3>Answer:</h3>
A) x = 2
<h3>Explanation:</h3>
<em>Try the answers</em>
Of the offered choices, the only ones that go through the given point are ...
... x = 2
... y = -5
The latter is horizontal and parallel to y = 7, so is not the choice you want. The appropriate choice is ...
... A) x = 2
_____
<em>Figure out the answer</em>
The given line is horizontal, so the line you want is vertical—of the form ...
... x = constant
The constant must be chosen so the line will go through a point with x=2. It should be obvious that the constant must be 2.
... x = 2 is perpendicular to y = 7 and goes through (2, -5).
Answer:
We take v in the vector space V different from 0. Since v is not 0, then
Lets take k>0 such that
Now, we take any vector w. We want to show that .
Since v is any non-zero vector, then this will prove that for any vectors a,b. The reason is that for any vector different from 0, lets name it x, there will exist a constant such that for any y (this is for the same reason a constant exists for v). Since y can be anything, then it can be v. But that means that , because v also has its constant k.
Now, lets show that . Lets take a constant c such that . We have that
Thus
Which means that
Which means that . As a consequence
Which proves what we were looking for.
Answer:
9 hours of work
Step-by-step explanation:
306/17 = 18 per hour
so 162/18 = 9
Step-by-step explanation:
let x be the another angle
so
x+40=90
x=90-40
x=50
The measure of missing angle is 50
