The horizontal distance is given by the formula:
tan θ=opposite/adjacent
where:
θ=21
opposite=2000 ft
adjacent=a
thus calculating for a we get:
tan 21=2000/a
thus
a=2000/tan 21
a=5210.18 ft
Answer: 5210.18 ft
The correct answer for this question is this one: "(80 + 50i) / 89" or <span>quantity of negative 80 plus 50 i over 89
</span>
The expression is <span><span>10 over quantity of 8 minus 5 i.
</span>10 / (8 - 5i)
= 10 / (8 - 5i) * (8 + 5i) / (8 + 5i)
= 10 * (8 + 5i) / (64 +25)
= (80 + 50i) / 89

Answer:
Step-by-step explanation:
Given: a graph
To find: the average rate of change of the amount of the element over the 10-minute experiment
Solution:
A rate of change of one quantity with respect to another quantity is known as rate of change. If y is the dependent variable and x is the independent variable then average rate of change = change in y /change in x.
From the graph,
change in x (time) = minutes
change in y ( amount of the element) = g
So, average rate of change =
Answer: It is B
