Answer:
24
Step-by-step explanation:
area = wl (6×4 = 24)
w width l length
We use the Work formula to solve for the unknown in the problem which is W = F x d. First, we solve for the Net Force acting on the car. The Net Force is the summation of all forces acting on the object. For this case, we assume that Friction Force is negligible thus the Net Force is equal to:
F = mgsinα in terms of SI units and in terms of english units we have F = m(g/g₀)(sin α) where g₀ is the proportionality factor, 32.174 ft lb-m / lb-f s²
F = 2500 (32.174/32.174) (sin 12°) = 519.78 lb
W = Fd = 519.78 lb (400 ft) = 207912 ft - lb or 20800 ft-lb
If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.
So,
1.
![7x^{7}-x-5](https://tex.z-dn.net/?f=7x%5E%7B7%7D-x-5)
![35x^{2}](https://tex.z-dn.net/?f=35x%5E%7B2%7D)
![\frac{x}{5}+2](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B5%7D%2B2)
are polynomials.
2.
![x^{2} -x\sqrt{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-x%5Csqrt%7B2%7D)
y
2 + s
![4x^{2} +y](https://tex.z-dn.net/?f=4x%5E%7B2%7D%20%2By)
are all polynomials.
3.
If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.
Hence,
is a cubic trinomial.
4.
The highest power is the degree.
Hence, degree of the polynomial is 2 + 4 = 6.
Answer:
B) ![\frac{7}{7^5}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B7%5E5%7D)
Step-by-step explanation:
![\frac{7^3*7^-2}{7^5} =\frac{1}{2401}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5E3%2A7%5E-2%7D%7B7%5E5%7D%20%3D%5Cfrac%7B1%7D%7B2401%7D)
![\frac{7}{7^5} =\frac{1}{2401}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B7%5E5%7D%20%3D%5Cfrac%7B1%7D%7B2401%7D)
hope this helped!
