Properties of Logs
logb(x/y) = log<span>bx</span> - log<span>by</span>.
therefore
log5 (4/7)= log5 (4)- log5 (7)
<span>Solve log 5 (4) and log 5 (7) with the base change of the logarithm</span>
<span>log 5 4 = log 4 / log 5 </span>
Use the calculator:
<span>
<span>log 5 4 =0.8613531161
</span></span>
log 5 7 = log 7 / log 5
<span>log 5 7 =1.2090619551</span>
<span>log5 (4/7)= log5
(4)- log5 (7)=-0.347708839</span>
to change from degrees to radians
multiply by pi/180
136 * pi/180 = 136/180 * pi
now simplify
34/45 * pi
.755556 * pi pi=3.14159
2.373648
to the nearest hundredth
2.37 radians
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
use Cos for y .... b/c we see that function above has all the pieces we are going to work with
use Sin for x .. for the same reason above
Cos(30) = y / 4
4
Cos(30) = y
4
/2 = y
2
= y
leave the answer for y like that.. it's in 'exact" form
now for x
Sin(30) = x / 4
4
Sin(30) = x
4
* 1/2 = x
2
= x
and leave your answer for x like that as it's in it's exact form. :)
oh and I see the answer in the list.. do you? :)
Answer:
1 and 1/8
Step-by-step explanation:
turn 3/4 times 2 and you get 6/8 then you add it
I hope I helped!
