<span>There is little to no data here. The height of an airplane as it descends to an airport runway is always dependent on its weight and the force of gravity acting on it. It also depends in the runway’s length and type of airplane it accommodates. Take note that every plane is different in size, mass and length. International, private and domestic planes varies in properties.<span> </span></span>
Answer:
Step-by-step explanation:
Part (A).
In this option, construction of perpendicular bisector of a segments has been given (Passing through the point of intersection of equal arcs marked from B and C and a point A).
Part (B).
Given construction is for the bisector of an angle (Passing through the point of intersection of equal arcs marked from B and C and vertex A).
Part (C).
In this part we are constructing a line perpendicular to a given line through a point not on the line (line passing through C and D and making an angle of 90° with AB).
Answer:
Your answers are correct except the 7th
7th Answer : 6 + 5a
Step-by-step explanation:
12) 2a - 8 = 14 ⇔ 2a = 22 ⇔ a = 11
13) 2(a + 3)
16) 3x - 1 = 7 ⇔ 3x = 8 ⇔ x = 8/3
This problem Is an example of geometrica progression. The formula
for the sum of geometric progression is:
S = a[(r^n)-1] / (r – 1)
Where s is the sum
a is the first term = 1
r is the common ratio = 2 ( because it doubles every year
n is the number of terms = (19) since the first term is when
he was born which he still 0
s = S = 1[(2^19)-1] / (2 – 1)
s = $524,287
