Answer:
k = - 6
Step-by-step explanation:
Given a function f(x), then a horizontal translation parallel to the x- axis is denoted by
f(x + k)
If k > 0 then shift of k units left
If k < 0 then shift of k units right
Here the shift is 6 units to the left, from 4 to - 2, hence
k = 6
So first of all you know that one side is 14cm and the other side is 6cm
What you would do is: 14-6=???
Your answer should be: 8cm
Answer:
0.8660
Step-by-step explanation:
cosine theta = -1/2
theta = cosinearctan(-0.5)
theta = 120
sine4theta = sine 4(120)
= sine480
= 0.8660
Hello :
v . w = <span>| | v | | × </span><span>| | w | | cos(</span><span>θ) ....(1)
v(2,0,1) w(0,1,-3)
</span>v . w = (2)(0)+(0)(1)+(1)(-3) = - 3
| | v | | = √((2)²+(0)²+(1)²) = <span>√5
</span>| | w | = √((0)²+(1)²+(-3)²) = √10
by (1) :
cos(θ) = (v . w ) / | | v | | × | | w | |
cos(θ) = = - 3/√50
θ =..... calculate by 2ind function ( calculator)
