Answer:
3/4 = z
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Divide 3 by 4, then subtract z from the result
3/4 - z
<u>Step 2: Solve for z</u>
3/4 - z + z = 0 + z
3/4 = z
Answer: 3/4 = z
The third one is correcte
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)
Answer:
Step-by-step explanation:
We are provided logarithmic equation , which is ,
- Here we took the base as 10 , since nothing is mentioned about that in Question .
Say if we have a expoteintial equation ,
<u>In</u><u> </u><u>logari</u><u>thmic</u><u> </u><u>form</u><u> </u><u>it</u><u> </u><u>is</u><u> </u><u>,</u><u> </u>

Similarly our required answer will be ,
