Answer:
b = 252 in
Step-by-step explanation:
cos theta = adjacent side over hypotenuse
cos 38 = b/ 320
Multiply each side by 320
320 cos 38= b/320 * 320
320 cos 38 = b
252.1634412 =b
To the nearest whole number
252 =b
I would say it is 248,700
For this case, what we must do is multiply the depth of the fish by the fraction of depth of the turtle.
We have then:
(-3/4) * (1/3) = (- 3 * 1) / (4 * 3) = - 1/4 mile
Therefore, the depth of the turtle on the surface of the water is:
-1/4 mile
Answer:
the turtle's depth is:
-1/4 mile
No. The third expression x^-3 + 4x is not a polynomial because the exponent is -3. Polynomials can have exponents but only 0, 1, 2, 3, and the rest of the positive integers are allowed. They can have constants and variables that can be combined by the four basic operations except division by a variable like 1/x or like the third expression x^-3 + 4x which is also 1/x^3 + 4x. The other three given expressions are polynomials.
Answer:
![2x - 4 = 10 \\ 2x = 10 + 4 \\ 2x = 14 \\ x = \frac{14}{2} \\ x =7](https://tex.z-dn.net/?f=2x%20-%204%20%3D%2010%20%5C%5C%202x%20%3D%2010%20%2B%204%20%5C%5C%202x%20%3D%2014%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B14%7D%7B2%7D%20%20%5C%5C%20x%20%3D7)
