Answer:
b
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius
The circle shown is centred at the origin and has a radius of 5, thus
x² + y² = 5² ⇒ x² + y² = 25 → b
Option B: 
is the correct answer.
Explanation:
The exponential equation is 
If 
, then 
Thus, the equation becomes
Applying log rule, 
and thus the equation becomes
Since, we know that, 
, using this we get,
Hence, the logarithmic equation which is equivalent to the exponential equation is
Thus, Option B is the correct answer.
D. He will have $2,121.80.
After one year at 3% interst, $2000 becomes $2000 x 1.03 = $2,060.
During the second year, that $2060 x 1.03 becomes $2121.80
Answer:
35 ok
Step-by-step explanation:
35 Men ok byeee3eeeeeeeeeeeeewwww
The reciprocal of a number (also called the multiplicative inverse) means 1/this number or (This number)^-1
So, to get the reciprocal of 7/2a, you need to divide 1 by this number as follows:
reciprocal = 1 / (7/2a) = 2a/7
The answer is : 2a/7
