The table shows the cost of renting movies online.

number of movies cost

1 $3.99

2 $7.98

3 $11.97

4 $15.96

5 $19.95

what does the rate of change mean in this situation?

a) the cost increases $11.97 for every additional movie rented .

b) the cost increases $7.98 for every additional movie rented.

c) the cost increases $3.99 for every additional movie rented.

d) the cost increases $15.96 for every additional movie rented

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
