A200-foot long support wire attaches to a cell phone tower at a height of 50 feet from the ground. to the nearest tenth of a foot, what is the distance along the ground from the center of the tower to the point where the wire touches the ground? 193.6 ft 21.2 ft 7.1 ft 206.2 ft

193.6 ft

Step-by-step explanation:

Since, the length of the wire = 200 ft,

And, the height of the tower = 50 ft,

Let x be the distance along the ground from the center of the tower to the point where the wire touches the ground,

By the below diagram,

Hence, the distance along the ground from the center of the tower to the point where the wire touches the ground is approximately 193.6 feet.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

answer is : muchas/tipicas

have a nice day!
