Answer: C. (8, 16, 4)

Step-by-step explanation:

Given the following:

Let:

Trucks = T ; Cars = C ; SUVs = S

T =0.5(C + S) - 2 - - - (1)

C = 2T - - - (2)

T + C + S = 28 - - - (3)

T = 0.5(2T + S) - 2

T = T + 0.5S - 2

0 = 0.5S - 2

0.5S = 2

S = 2/0.5

S = 4

From T + C + S = 28

C = 2 T ; S = 4

T + 2T + 4 = 28

3T = 28 - 4

3T = 24

T = 24/3

T = 8

From T + C + S = 28

8 + C + 4 = 28

12 + C = 28

C = 28 - 12

C = 16

Hence, (T, C, S) = (8, 16, 4)

poizon [28]
First find the time that the ball is level with the top of the building on its descent. You can do this by  solving 280 = -16^2 + 48t + 280 for t. This gives t = 3 seconds . 
Then when the ball reaches the ground the  time t is obtained by solving 0 = -16t^2 + 48t + 280  This gives t = 5.94 seconds.

2.8, 3.4, 4.0, 4.6, . . . Write an equation for the nth term of the arithmetic sequence. Then find a50.
vova2212 [387]

Answer:

a_n = 2.2 + 0.6 n

a_50 = 32.2

Step-by-step explanation:

What's the common difference of this series?

a_1 = 2.8

a_2 = 3.4

Common difference = a_2 - a_1 = 3.4 - 2.8 = 0.6.

Expression for the nth term:

a_n = a_1 + (n - 1) \cdot\text{Common Difference} \\\phantom{a_n } = 2.8 + 0.6 \; (n-1) \\\phantom{a_n} = 2.8 + 0.6 \; n - 0.6\\\phantom{a_n} = 2.2 + 0.6\; n

n = 50 for the fiftieth term. Therefore

a_{50} = 2.2 + 0.6 \times 50 = 32.2.
