Answer:
e) cos(90° - x)
Step-by-step explanation:
we know that
If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa
The complementary angle of angle x is equal to (90-x) degrees
therefore
23,456
x 86
If we calculate the conventional way,
This gives us 23,456 * (6 + 80)
= (23,456 * 6) + (23,456 * 80)
First, we multiply 23456 by 6, the figures obtained will be 140736 (which is given in the question)
Next, we multiply 23456 by 80, the figures obtained will be 1,876,480
The third option is the correct answer
Answer:
Solve the 1st equation for y and then you substitute the answer of the y value to the other equation to get the x value
A rational number times a rational number=rational numberan irrational number times a rational number=irrational number
remember, a rational number is a number that can be written as a/b where a and b are integers and b≠0
A is irrational because the pattern doesn't repeatb is irrational because it's a crazy square rootC is irrationalD is not irrational, it is a fraction
answer is D
Written form is just how you would usually see a number. So it would be 3,680,010.
