Answer:
10472. 4 ft
Step-by-step explanation:
Let the height of the plane above the helicopter be "h"
We have a right triangle where the side opposite the 71 degree angle = h and the side adjacent to this angle = 3055
So we can use the tangent here
tan (71) = h / 3055 multiply both sides by 3055
3055 * tan (71) = h ≈ 8872.4 ft
So.......the total altitude of the plane is
1600 + 8872.4 =
10472. 4 ft
The solution set of the inequality x ≥ - 4 using set builder notation and interval notation is {x | x ∈ Z, - 4 ≤ x ≤ ∞ } and [ - 4, ∞ ) respectively.
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.
A set can be represented by its elements or the properties that each of its members must meet can be described using set-builder notation.
Interval Notation: A set of real numbers known as an interval contains all real numbers that fall inside any two of the set's numbers.
Consider the inequality,
x ≥ - 4
In the number line, the value of x is equal to and greater than - 4 increasing to infinity.
Therefore,
The solution set using the set builder notation is:
{x | x ∈ Z, - 4 ≤ x ≤ ∞ }
The solution set of the inequality using the interval notation is:
[ - 4, ∞ )

Answer:
1/2y+3/2
2y+-1/2
-3/2b-2x+5
Step-by-step explanation:
The first question would be x + (x + 4). This is because Max has $x and Keisha has (x + 4) because she has four MORE THAN Max. I am pretty sure that the second one is A, but I am not positive. The first one is right though. I hope this helps!!!
