Step-by-step explanation:
what you need to do is look at the question again it say 10 feet above sea level and the other one is 7 feet below sea level. now read your question again hope you find the answer good luck
Let's solve your inequality step-by-step.<span><span>−28</span><<span>v−16</span></span>
Step 1: Flip the equation.<span><span>v−16</span>><span>−28</span></span>
Step 2: Add 16 to both sides.<span><span><span>v−16</span>+16</span>><span><span>−28</span>+16</span></span><span>
v><span>−12</span></span>
Answer:<span>v><span>−<span>12</span></span></span>
The x intercepts must be 1 and -4, so C.
Answer:
B. 39.59
Step-by-step explanation:
So 43 degrees, you know the length of the opposite side (27) and the angle (43 degrees), the only unknown is the hypotenuse. So you're looking for a trigonometric ratio that uses the angle (all of them do, except technically the inverse don't), the opposite side, and the hypotenuse. Sine is defined as
. So let's plug in known values:
![sin(43) = \frac{27}{x}](https://tex.z-dn.net/?f=sin%2843%29%20%3D%20%5Cfrac%7B27%7D%7Bx%7D)
Multiply both sides by x
![sin(43) * x = 27](https://tex.z-dn.net/?f=sin%2843%29%20%2A%20x%20%3D%2027)
divide both sides by sin(43)
![x=\frac{27}{sin(43)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B27%7D%7Bsin%2843%29%7D)
Normally I would use a calculator, but in this case I'll use the approximation given in the problem of 0.682
![x=\frac{27}{0.682}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B27%7D%7B0.682%7D)
simplify the fraction
![x\approx39.59](https://tex.z-dn.net/?f=x%5Capprox39.59)
