Answer:
i need some bleach for my poor brain
Step-by-step explanation:
Answer:
if we were to put this together, it would be <em>3i+1 </em>or <em>1+3i</em>. <em>i</em> would be the variable,<em>3</em> the coefficient.
Step-by-step explanation:
The triangle equation is (side*side)/2
Therefore, we can write the equation as (5*16)/2
After you calculate the equation, we can get the answer of 40, the answer would be D.
Hope that helps :D

Conditional statement.</h2>
A mathematical statement of the form 'If A Then B' is a conditional statement.
<h3>
Explanation:</h3>
A conditional statement in geometry is an if-then statement consisting of a hypothesis and a dependent conclusion. The structure of a conditional statement is:
<em>If (......hypothesis......), then (......conclusion......)</em>
If hypothesis = A and conclusion = B, the mathematical expression for a conditional statement is: <u>A → B</u> and it is read as <u>If A then B.</u>
A conditional statement is always true unless the hypothesis is true and the conclusion is false.
A conditional statement can be written in form of its converse, inverse and contrapositive.
<u>Example of a conditional statement is</u>
A = I am 18 years old
B = I am an adult
A conditional statement is of the form (<u>A → B</u>) "If A then B"; therefore
If I am 18 years old, then I am an adult.
Answer:
4833 m
Step-by-step explanation:
Given that her angle of elevation at the first recording is 47.3 at an altitude of 4900 m
We use Pythagoras Theorem to get this done
We can say that the opposite of the angle is the altitude, while the hypotenuse of the triangle, is the distance between herself and the top
Using the sine angle rule, we have
Sine 47.3 = 4900 / h
h = 4900 / sin 47.3
h = 4900 / 0.7349
h = 6668 m
This means that she was 6668 m away from the top of the mountain
She then moves 1000 m closer to the mountain top, this means that our h = 6668 - 1000
Using the same sine angle rule, we have
Sine 58.5 = o / 5668
o = 5668 * sine 58.5
o = 5668 * 0.8526
o = 4833 m
She is 4833 m above the sea level
