Answer:
x ≈ 2.76
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan78° = 
= 
= 
( multiply both sides by x )
x × tan78° = 13 ( divide both sides by tan78° )
x = 
≈ 2.76 ( to 2 dec. places )
Answer:
(-5,9)
Step-by-step explanation:
<span>In the given mathematical value of 5,000 to round off this number to the nearest hundred, we can elaborate the number values using the expanded form to clearly see the order position: </span><span><span>1. </span> 5,000 = thousands
</span><span>Now we can observe the numerical value of 4,900 as the rounding number which becomes
4900 = 5000
4800 = 5000
4700 = 5000
4600 = 5000
4500 = 5000

Step-by-step explanation:
Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form.
For example, instead of writing 0.0000000056, we write 5.6 x, 10^-9
