Gravitational force is directly related to mass and inversely related to distance. So the bigger the masses the greater the force and
the greater the distance the smaller the force. According to the model, which sphere has the greatest gravitational attraction to
sphere D?
A. sphere c because it is the largest sphere
B. sphere a because it is the smallest and the closest
C. Sphere c because it is larger than A and closer than B
D. Sphere B because it is larger and farther away from C

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

5/20 so 25%
