Let's solve it step by step:
(we start with the innermost bracket: (25/5). This is equal to 5. :
25+{2[3+8-7(25/5)+11]} =
25+{2[3+8-7(5)+11]} =
now, we can multiply 7 and 5, which is 35
25+{2[3+8-35+11]} =
Now we can add all the numbers in the square bracket, 3,8 (that's 11), then -35 (which is -24) then 11 - all together it's -13
3+8-35+11=22-35=-13
25+{2[-13]} =
Multiplying 2 and -13
25+{-26} =25-26, which is -1
the final answer is -1
Answer:
Step-by-step explanation:
Several trig identities are involved in the proof of this. This is the order in which they are used.
- cos(2x) = cos²(x) -sin²(x)
- cos²(x) +sin²(x) = 1
- cos(x) = 1/sec(x)
<h3>Proof</h3>
Starting with the left side, we can transform it into the right side.

Hey there! :)
Answer:
56.7 kg.
Step-by-step explanation:
Use the density formula to solve for the mass:
D = m/V.
Rearrange in terms of mass, or 'm':
DV = m.
Solve for the volume:
0.06 × 0.9 × 1.5 = 0.081 m³.
Plug this into the equation along with the density:
700 × 0.081 = 56.7 kg.
