The values of p for which the equation px = 10 have a solution −5; 1; 20 is -2, 10,
<u>Solution:</u>
Given, equation is px = 10.
We have to find the values of p for which solutions of given equations becomes -5, 1, 20.
We just need to substitute -5, 1, 20 in given equation as x, to values of p.
Now, For -5 ⇒ p(-5) = 10 ⇒ -5p = 10 ⇒ p = -2
For 1 ⇒ p(1) = 10 ⇒ p = 10
For 20 ⇒ p(20) = 10 ⇒ 20p = 10 ⇒ p =
Hence, the values of p are -2, 10, for the solutions -5, 1, 20 respectively.
Answer:
The relation for the area of circle with radius , Diameter , circumference is
A= × radius²
A =
A =
Step-by-step explanation:
Given as :
The formula for the area of circle = × radius²
I.e A = × radius²
<u>Now If we know radius then </u>
Area calculated as A= × radius²
<u>If we know Diameter then</u>
Area calculated as × (
)²
Or, A = × (
)²
I,e A =
<u>If we know the circumference then</u>
∵ circumference = c = 2 × × radius
or, c = 2 × × r
from here we calculate radius
I.e r =
And So , Area ( A ) = × radius²
I.e A = × (
)²
Or, A =
Hence The relation for the area of circle with radius , Diameter , circumference is
A= × radius²
A =
A = Answer
