He spent 12 dollars on each oou day
Answer:
<h2>
<u>GIVEN</u><u> </u>- </h2>
- Water tank which is in a shape of right rectangular prism
Dimensions = 6 feet × 4 feet × 7 feet
<h3><u>TO</u><u> </u><u>FIND</u><u> </u><u>-</u><u> </u>
</h3>
<h2><u>SOLUTION</u>
- </h2>
<em><u>Using</u></em><em><u> </u></em><em><u>formula</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>surface</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>right</u></em><em><u> </u></em><em><u>rectangular</u></em><em><u> </u></em><em><u>prism</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em>
Surface area =
L = length
w = width
h = height
( assumimg 6 feet = L , 4 feet = W , 7 feet = h)
Putting value of L, W and H in the equation. we get,
=2(4 × 6 + 7 × 6 + 7× 4)
= 2(24 + 42 + 28)
= 2( 94)
= 2 × 94
= 188
<span>Triple 4 and subtract 2 each day
Find the number of days to be able to reach zero
1st day = 3(4) – 2
=> 12 - 2
=> 10
2nd day
=> 10 - 2
=> 8
3rd day
=> 8 – 2
=> 6
4th day
=> 6 – 2
=> 4
5th day
=> 4 – 2
=> 2
6th day
=> 2 – 2
=0
In 6th day, you’ll be able to get the amount of zero by subtracting
3(4) by 2.</span>
Yes they are the same because they equal each other
Answer:
see explanation
Step-by-step explanation:
Consider the left side
Using the trigonometric identities
csc x = and sec x =
Note that sin( - x) = cos x
Hence
csc( - x)
=
=
= sec x = right side ⇒ proven
