Workers at a quarry are removing rock at a daily rate of 0.1%. There are 3.2 tons of rock when the work begins. Which function can be used to find the number of tons of rock left at the end of d days?
A. m(d) = 3.2(0.999)^d
B. m(d) = 3.2(0.99)^d
C. m(d) = 3.2(1.01)^d
D. m(d) = 3.2(1.001)^d

c

Step-by-step explanation:

The Answer is m(d) = 3.2(0.999)^d

Step-by-step explanation:

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
