The circumference is (2 pi) (radius) . The ratio of radius to circumference is (1)/(2 pi).
Answer:
2.44
Step-by-step explanation:
Given: x³ + 2x² - 5ax - 7 and x³ + ax² - 12x + 6
Also, R1 + R2 = 6
in order to find the value of a:
Let p(x) = x³ + 2x² - 5ax - 7 and q(x) = x³ + ax² - 12x + 6
Using remainder theorem i.e if a polynomial p(x) is divisible by polynomial of form x - a then remainder is given by p(a).
Then,
R1 = p( -1 ) = (-1)³ + 2(-1)² - 5a(-1) - 7 = -1 + 2 + 5a - 7 = 5a - 6
R2 = q( 2 ) = 2³ + a(2)² - 12(2) + 6 = 8 + 4a - 24 + 6 = 4a - 10
Now,
R1 + R2 = 6
5a - 6 + 4a - 10 = 6
9a = 22
a=2.44
Therefore, Value of a is 2.44
The answer to your question is -4
Good evening
Answer:
A) 6
Step-by-step explanation:
Firstly, the solution set to the inequality is : x > 7
Because, x + 8 > 15 ⇌ x > 15 - 8 ⇌ x > 7
Hence
The only number that is NOT in the solution set is 6
