Answer: A, Magnitude of 8 and direction angle equal to 0°
Step-by-step explanation:
Since vector u is only a straight line, there will be no angle, which means that answers B and D are automatically wrong.
Now, we’re going to use the distance formula to find the component form of vector u
Now we found the new coordinate, which is (8,0), and it is being extended from the origin with the same angle of 0°
Using the formula from above, we can find the magnitude of vector u
Hope I explained it well and hopefully this helps!
The diagonal of a cube is the square root of 3x^2, where x is a side length....The three dimensional diagonal is the counterpart to the two dimensional hypotenuse found in a right triangle...mathematically a three dimension diagonal can be found with an extension of the Pythagorean Theorem adapted to three dimensions...
d^2=x^2+y^2+z^2 but since we are dealing with a cube, x=y=z=s where s is a side lenght...
d^2=3s^2 and we are told that the diagonal is 30 in. so
3s^2=30^2
3s^2=900
s^2=300
s=√300
s=10√3 in. exact
s≈17.3 in. (to the nearest tenth of an inch)
Answer:
The equation is:
The sum is:
--------------------------------------------------------------------
If the sequence is infinite, the formula is:
-------------------------------------------------------------------
Step-by-step explanation:
We must calculate the radius of the geometric series
The first term of the series is:
The last term of the series is:
If the sequence is finite then the formula is:
If the sequence is infinite then by definition as the radius are then the formula for the sum of the geometric sequence is:
B is the answer
the formula is :
which r stands for radius
and h stands for height
the diameter is 16
so the radius is
hope you understand it
