Answer:
distributive property of binary operations generalizes the distributive law from elementary algebra, which asserts that one has always {\displaystyle x\cdot =x\cdot y+x\cdot z.} For example, one has 2 ⋅ = +. One says that multiplication distributes over addition.
<h3>☞<u> </u><u>Correct Question</u>: - </h3>
In how many years will rupees 2000 amount to rupees 2420 at 10% per annum compound interest.
<h3>➩ <u>Solution</u>: - </h3>
Given,
P= Rs 2000
A= Rs 2420
R= 10 %
A = P(1 + R/100)ⁿ
⇒2420 = 2000(1 + 10/100)ⁿ
⇒2420/2000 = (11/10)ⁿ
⇒121/100 = (11/10)ⁿ
⇒(11/10)² = (11/10)ⁿ
⇒n = 2
∴ In 2 years rupees 2000 will amount to rupees 2420 at 10% per annum compound interest.

Step-by-step explanation:
the closed circles are the 2 out of ___
Answer:
the height is 9
Step-by-step explanation:
To find the answer, we first need to understand the formula to find the volume of a cone:
Volume = 1/3 x base area x height
In this case, we can put the given information into the formula.
The base area of the cone: pi(radius)^2 = pi(3)^2 = 9pi
We can then find the height:
27pi = 1/3 x 9pi x height
27pi/9pi = 1/3 x height
3 = 1/3 x height
height = 9
Therefore, the height is 9cm.

Answer:
y = -1/2x -3
Step-by-step explanation:
The line perpendicular to one with a slope of 2 will have a slope that is the negative reciprocal of 2, that is, -1/2. The given point is the y-intercept of the required line, so we can write its equation directly in slope-intercept form:
y = mx + b
where m is the slope (-1/2), and b is the y-intercept (-3). Your line is ...
y = -1/2x -3
