<span>sin(2x)= 2sin(x)cos(x)
can you finish the rest or need more help?
sin(6/5) should be the answer
so we have 2 sin(0.6)cos(0.6)
we know its sin (2x) identity
x=0.6
so its sin(2*0.6)</span>
1. C (x+8)^2
2. D y=6^x
3. D t/2.35 ; 2.13 ft.
4. A (7h^2-2h)/2; 672 cm^2
5. A 4.50 h ; $7.88
For one and two you just have to plug in the numbers into the equation to see what works.
Three four and five you have to read the problems and come up with an equation to get your answer. Please comment if you need to see the work!
To find this answer, we must first find the percentage of batteries that are defective. We can do this by dividing 3 by 500.
3 / 500 = 0.006
So our percentage of defective batteries is 0.6%.
Now, to find out how many defective batteries would be in a batch of 12000, we just need to multiply the constant (percentage of defective batteries) by the amount in the new batch.
12000 * 0.006 = 72
In a shipment of 12,000 batteries, 72 will be defective, so the correct answer choice would be B.
Hope that helped =)
Answer: 5.3
Step-by-step explanation: Do 9.8 (Friend swim depth) - 4.5 (dolphin jump height) to get your answer.
