An exponential equation can be written from its description using the form
... y = (reference value)·((later value)/(reference value))^((t - (reference time))/(later time - reference time))
Here, we have
... reference value = 220; reference time = 2; later value = 880; later time = 4
so we can write the exponential equation as
... y = 220·(880/220)^((t-2)/(4-2)) = 220·4^(t/2 -1) = 55·2^t
Then for t=10, the expected number is
... y = 55·2^10 = 56,320

Answer:
y² = (1/16)x³
Step-by-step explanation:
Given that :
y² varies directly as the cube of x
y² α x³
y² = kx³ - - - (1)
Where, k = constant of f proportionality
We can obtain the value of k ; when x= 4 and y = 2
2² = k4³
4 = 64k
k = 4/64
k = 1/16
Putting k = 1/16 in (1)
y² = (1/16)x³
Answer:
<u>According to theorem, in a 30°-60°-90° triangle the sides are in the ratio 1 : 2 : √3</u>.
- Base – 1
- Hypotenuse – 2
- Perpendicular – √3
Side length of the hexagon is the base of the right triangle, so it is 1.
Let r is the radius of the incircle in a regular hexagon. 2r is the diameter of the incircle. It is also the hypotenuse of the right triangle. so, it is 2.
<u>On using Pythagorean property</u>,
p² + b² = h²
- 1² + b² = 2²
- b² = 2² - 1²
- b² = 4 - 1
- b² = 3
- b = √3
<u>Note</u>: See picture attached.
