Let's start by understanding that the graph is a linear line. We have a common difference if 4.5 for every 10x we have more.
We can start by finding the gradient, using rise over run. Let's take (10, 4.5) and (20, 9)
Our rise is 9 - 4.5 = 4.5 and our run is 10. Then, our gradient becomes 4.5/10 = 0.45
Now, we can substitute points using the point-slope form.
y - 4.5 = 0.45(x - 10)
y - 4.5 = 0.45x - 4.5
Hence, our line becomes y = 0.45x and you can verify by substituting in points from the table.
C. 14.9 because the second number is 5 so you drop the seven and the 5 and round the 8 up to 9
Answer:
-1=y
Step-by-step explanation:
Hi there!
Th' following triangle is divided into 2 sub-triangles!
• In 1ˢᵗ triangle :-
tan 45° =

⇒ 1 =

⇒

= 5
• In 2ⁿᵈ triangle :-
cos 30° =

⇒

=

⇒

= 2 × 5
⇒

= 10
Hence,
Th required answer is 10 units.
~ Hope it helps!
