Answer:
7x^4+x^3 (or 7x^4 + some random term)
Step-by-step explanation:
Since the polynomial expression must be a binomial, it must have two terms.
Since the binomial must have a degree of 4, and the leading coefficient must be 7, then a possible binomail could be 7x^4+x^3 because you have two terms, 7x^4 and x^3 while the degree is 4 and the leading coefficient is 7.

Answer:
0.02 mm
Step-by-step explanation:
Let's convert the numbers given in decimal first, for ease of calculation.
Thickness of soles of feet = 1 2/5th mm, which is 1.4 mm
THick ness of eyelids are 1/70 TIMES the thickness of soles
So we multiply 1/70 [in decimal that is 0.0143 (rounded to 4 decimals) ] with 1.4:
0.0143 * 1.4 = 0.02 mm
So, the thickness of skin on your eyelids is 0.02 mm

Answer:
1. area DEF = 2π cm²
2. arc JK = 2π cm
Step-by-step explanation:
1. The area is given by ...
A = 1/2r²θ . . . . . where r is the radius and θ is the central angle in radians
Your sector has an area of ...
A = (1/2)(3 cm)²(80(π/180)) = (1/2)(9 cm²)(4/9π)
A = 2π cm²
__
2. The length of an arc is ...
s = rθ . . . . . . . where r is the radius and θ is the central angle in radians
s = (5 cm)(72(π/180)) = (5 cm)(2/5π)
s = 2π cm . . . arc length
_____
<em>Additional comment</em>
There are π radians in 180°, so an angle in degrees can be converted to an angle in radians by multiplying by π/180°. (The units of degrees cancel, leaving a pure number. "Radians" have no units.)
