Answer:
Option (B)
Step-by-step explanation:
Let the equation of the exponential function give in the graph is,
f(x) = a(b)ˣ
Since the given graph passes through two points (0, 3) and (-1, 1.5)
For (0, 3),
f(0) = a(b)⁰
3 = a(1) [Since b⁰ = 1]
a = 3
For (-1, 1.5),
f(-1) = a(b)⁻¹
1.5 = 3(b)⁻¹
1.5 =
b =
b = 2
Therefore, equation of the given function will be,
f(x) = 3(2)ˣ
Option (B) will be the answer.
Answer:
(c) 4 small squares
Step-by-step explanation:
Given
<u>Small Square:</u>
<u>Large Square:</u>
i.e. twice as long as the small square
Solving (a): The area of the small square.
This is calculated as
So, we have:
Solving (b): The area of the large square.
This is calculated as
So, we have:
Solving (c): Number of small square to cover the large square
To do this, we simply divide their areas.
Let n represents the required number; n is calculated as:
<em>Hence, 4 small squares is required to cover the large square</em>
