Answer:
3 feet
Step-by-step explanation:
Initial depth = 16 feet
<u>Then:</u>
- 16 - 8 - 5=
- 8 - 5 =
- 3 feet depth left
Answer:
Step-by-step explanation:
3 sinθ=3 cos 2θ
sin θ=cos 2θ
sinθ=1-2sin² θ
2sin²θ+sin θ-1=0
2sin²θ+2sinθ-sinθ-1=0
2sin θ(sin θ+1)-1(sin θ+1)=0
(sin θ+1)(2 sin θ-1)=0
sin θ=-1=-sin 90=sin (180+90)
θ=270
or sin θ=1/2=sin 30,sin (180-30)
θ=30,150
solution set is {30,150,270}
Step 1
<span>Calculate the error
</span>error=75-64-----> 11 ft
step 2
<span>Divide the error by the exact value
</span>11/64=0.1719
step 3
<span>Convert that to a percentage
</span>0.1719*100=17.19%
the answer is
17.19%
3 times negative 11 is negative 33 and 3 times 2 is 6, so you have negative 33 divided by 6 and that is negative 5.5
Answer: the answer is 521
