8/20=12/x Cross multiply 8x=20×12 8x=240 Now divide
X = 240÷8 X=30
So 30 ft
Answer:
[Distance to the Horizon]^2 =Height of the skydiver x Diameter of the Earth
D^2 = 1.4 x 7918
D^2 = 11,085.2
D = Sqrt(11,085.2)
D = ~ 105.28628......miles - Distance to Horizon.
Step-by-step explanation:
Answer:
h(x) = 1/4 x - 2
Step-by-step explanation:
f(x) = 4x + 8
y = 4x + 8
x = 4y + 8
4y = x - 8
y = 1/4 x - 2
h(x) = 1/4 x - 2
Answer:
x = <u><em>8</em></u>
The missing measures are <em><u>85</u></em> degrees
Step-by-step explanation:
Since 9x + 13 and 11x - 3 are on opposite sides, they are equal, so
9x + 13 = 11x - 3
Subtract 13 from both sides:
9x = 11x - 16
Subtract 11x from both sides:
-2x = -16
Divide both sides by -2:
x = 8
The angle measures are
9(8) + 13 = 72 + 13 = 85
11(8) - 3 = 88 - 3 = 85
Answer:
Domain- [-4,∞) ; Range- [-2,∞)
Step-by-step explanation:
For Domain, we need to find the range of value for x,
As the value for x+4 should be positive or 0 because it is under the square root bracket sign.
x ∈ [-4,∞)
For the range of values, we need to find all the possible value of y
As the value given by the square root will always be greater than equal to 0.
Therefore ,
y ∈ [-2,∞)
