Find the missing length ‘x’
1 answer:
Answer:
x = 13
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here A = 55, h = 5. b₁ = x, b₂ = 9, then
× 5 × (x + 9) = 55
2.5(x + 9) = 55 ( divide both sides by 2.5 )
x + 9 = 22 ( subtract 9 from both sides )
x = 13

Answer:
We conclude that the function represents exponential growth.
Step-by-step explanation:
Given the function
As the function is of the form
- y=abˣ
and base 'b' > 1
We know that when the base 'b' of the exponential function > 1, meaning those numbers will get bigger, we call it exponential growth.
As b=8/5 is bigger than 1.
i.e. 8/5 > 1
Thus, we conclude that the function represents exponential growth.
