Answer:
f(x) = 2^(2x+1)
Step-by-step explanation:
2 = 2¹
8 = 2³
32 = 2⁵
128 = 2⁷
1,3,5 and 7 are odd numbers.
Individual numbers in mathematics are represented as 2x + 1.
Answer:
Step-by-step explanation:
<u>Pendulum</u>
The length of the pendulum is 0.4 m or 40 cm. When swinging, it reaches the top height of 4 cm from the bottom. The geometric construction of this situation is shown in the image below.
The right triangle is formed by the length of the pendulum (40 cm), its horizontal displacement, and the vertical height projected by the pendulum.
This last distance is calculated subtracting the total length of the pendulum and the vertical displacement reached in its higher position.
We need to calculate the angle θ, for which we'll use the cosine since we know the adjacent leg and the hypotenuse:
The angle is
I think it is m= 5/2 and 1/5
Answer:Two
Step-by-step explanation:
Given
One coat of waterproofer cover
For two coating of waterproofer area of wooden crate remain same so we need same amount of waterproofer to cover it with second coat
So, we require two can of waterproofer to get double coating
1,159cm^2 that is the answer
