(<em>u</em> × <em>v</em>) • <em>w</em> makes sense, since <em>u</em> × <em>v</em> is another vector, and so (<em>u</em> × <em>v</em>) • <em>w</em> is a scalar.
<em>u</em> × (<em>v</em> • <em>w</em>) does not make sense, since <em>v</em> • <em>w</em> is a scalar, and the cross product is not defined between a vector and a scalar.
(<em>u</em> × <em>v</em>) × <em>w</em> makes sense, since <em>u</em> × <em>v</em> is a vector and so is <em>w</em>.
<em>u</em> • (<em>v</em> • <em>w</em>) does not make sense, since <em>v</em> • <em>w</em> is scalar, and the dot product is not defined between a vector and a scalar.
For this case we have the following equation:
6y = 3x
From here, we must clear the value of y.
We have then:
y = (3/6) x
Rewriting we have:
y = (1/2) x
The proportionality constant is:
k = 1/2
Answer:
the constant of proportionality in the equation 6y = 3x is:
1/2
Subtract 10 from both sides
A=55-10
=45
If any of these are a solution or answer even if it is close enough,
they may be
f(n) = 27 + 3d
f(n+27) = 3d
the second one is just an alternate version that math doesn't use often.
Answer:
2.5.
Step-by-step explanation:
Given equation:
(4 * 5) / 8
Multiply:
4 * 5 = 20.
Divide:
20 / 8 = 2.5
