we start by opening the brackets so it will be -25 plus 15 v is equals to 115. negative times a negative is a positive so -5 times -3 we we have gotten positive 15v there I hope you understood so our new equation is -25 + 15v is equals to 115 collect the like terms 15v is equals to 115 + 25 15 v is equals to 140 divide both sides by 15 so v is equals to 9 and 1/3
Answer:
Step-by-step explanation:
we can say the angle is also +45° going in the clock wise direction. so take Tan(45)= 1
Cot(45) = 1
b/c Tan(45) = Sin(45) /Cos(45) = (
/2) / (
/2) ofc that's just 1
b/c Cot(45) = Cos(45) / Sin(45) , which is the same as above 1
Answer:
32h^7
Step-by-step explanation:
(4h^4)3=64h^12
64h^12/2h^5=
32h^12/2h^5=32h^7
Hope this helps :)
Answer: The value of c would be 26.514 lb.
Step-by-step explanation:
Since we have given that
Mean = 17 lb
Standard deviation = 3.3 lb
At 99% level of significance, z = 2.58
So, it becomes,
![Z=\dfrac{X-\mu}{\sigma}\\\\2.58=\dfrac{X-17}{3.3}\\\\2.58\times 3.3=X-17\\\\8.514+17=X\\\\X=25.514](https://tex.z-dn.net/?f=Z%3D%5Cdfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%5C%5C%5C%5C2.58%3D%5Cdfrac%7BX-17%7D%7B3.3%7D%5C%5C%5C%5C2.58%5Ctimes%203.3%3DX-17%5C%5C%5C%5C8.514%2B17%3DX%5C%5C%5C%5CX%3D25.514)
So, the weight c would be
![c=25.514+1\\\\c=26.514](https://tex.z-dn.net/?f=c%3D25.514%2B1%5C%5C%5C%5Cc%3D26.514)
Hence, the value of c would be 26.514 lb.
