Answer: 19,244 ft

Step-by-step explanation:

1. To solve this exercise you can apply the formula for calculate the distance between two points, which is:

d=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}

2. Then:

d_{AB}=\sqrt{(6,000-1000)^{2}+(7,000-8,000)^{2}}=5,099.01

d_{AC}=\sqrt{(5,000-1000)^{2}+(1,000-8,000)^{2}}=8,062.25

d_{AC}=\sqrt{(5,000-6000)^{2}+(1,000-7,000)^{2}}=6,082.76ft

3. Add the distance obtained to calculate the perimeter of the triangle. Therefore, the fence needed to the nearest food is:

P=5,099.01ft+8,062.25ft+6,082.76ft=19,244.02ft=19,244ft

Can anybody help me with this ?
frutty [35]

f(x) = (3/4)ˣ - 4

As x gets really negative (3/4)ˣ grows positively without bound (because it's (4/3)⁻ˣ and 4/3 > 1).

As x gets really positive (3/4)ˣ tends to zero but never quite gets there.

So (3/4)ˣ > 0 for all x

So f(x) > 0 - 4 for all x

Answer:  { y   | y > -4  }, first choice
