Delicious77 [7]

Answer:the height of the balloon is 670.244 feet

Step-by-step explanation:

The right angle triangle BLD represents the scenario.

h represents the height of the balloon.

We would apply trigonometric ratio to determine h.

Tan # = opposite side/adjacent side

Looking at triangle LCD,

# = 61 degrees

h = opposite side

x = adjacent side

Tan 61 = h/x

1.7321 = h/x

h = 1.7321x

Looking at triangle LBD,

# = 54 degrees

h = opposite side

x + 100 = adjacent side

Tan 54 = h/x + 100

1.3764 = h/x + 100

h = 1.3764(x + 100)

Therefore,

1.7321x = 1.3764(x + 100)

1.7321x = 1.3764x + 137.64

137.64 = 1.7321x - 1.3764x

137.64 = 0.3557x

x = 137.64/0.3557 = 386.955

h = 1.7321x = 386.955 × 1.7321

h = 670.244 feet

Identify the range of the fuction shown in the graph
Viefleur [7K]

The answer would be B. -2 < x < 2 because if you look at the graph, the range would be left and right. So, the farthest to the left would be -2 and the farthest to the right would be 2.

It wouldn't be all real numbers.

Simplify to create an equivalent expression 2-6(-5t+1)
Mariulka [41]

Answer:

30t - 4

Step-by-step explanation:

Remember to follow PEMDAS. First, distribute -6 to all terms within the parenthesis:

2 -6(-5t + 1) = 2 + (-6 * -5t) + (-6 * 1)

2 + (30t) + (-6) = 2 + 30t - 6

Simplify. Combine like terms:

2 + 30t - 6 = 30t + (-6 + 2) = 30t - 4

30t - 4 is your answer.
