Answer:
Step-by-step explanation:
The given notation is not clear enough, but I will asume that the question is: "Wich is the vector lenght of the vector in a 3 dimensional euclidean space"
Vector lenght of a vector is given by the next formula:
║║=
In this case we have a=2, b=3 and c=1. We should substitute these values in the formula given before to obtain:
║║=
Wich is the answer to the problem.
Here, we need to set up the ratios.
height / width = 3 / 4
So, what is the width if the height is 4.5?
4.5 / width = 3/ 4
Cross multiply
18 = 3 width
6 = width
Answer:
42
Step-by-step explanation:
add both bases together and divide by 2 and multiply by height
so= 1+6/2 x 12
Answer:
Substitute the value of 7 into the variable x. Then solve the equation.
f(7) = 10 - 2(7)
f(7) = 10 - 14
<h2><em><u>
f(7) = -4 is the answer.</u></em></h2>
