Answer: y>-3 and x is all real numbers
3 more than the produce of 12 and 4.
The answer is C, 25% increase. To find the increase, subtract starting value (780) from the final value (975). It equals out to be 195. Divide 195 by the starting value which turns out to be 0.25. Then, multiply 0.25 by 100 which equals out to be 25.
Answer: The correct option is (c)
Step-by-step explanation: We are given to solve the following quadratic equation by the method of completing the square:
Also, we are to find the constant added on both sides to form the perfect square trinomial.
We have from equation (i) that
So,
Thus, the required solution is and the value of the constant added is
Option (c) is correct.
Answer:
a. 1,275.49 m²
Step-by-step explanation:
SA = 2πr² + 2πrh
SA = 2π(7)² + 2π(7)(22)
SA = 98π + 308π
SA = 406π
SA ≈ 1,275.49 m²
