Answer:
The directrix is y=6 and focus is (0,4)
The equation of the parabola is,
20-4y=x²
The answer is C. 3 3/4 is the answer.
Move the 11x to the left and the +54 to the right. Their signs will flip:
14x-11x = 96-54
3x = 42
x = 14
Let's label the man's age "x" because it's the unknown value that we're trying to find. Remember that the daughter's age is represented y "a."
x = 4a-3 would be an expression to represent the man's age :)
Answer:
B
Step-by-step explanation:
Well you can get rid of c and d since 9^2 = 81. so 74 is less than 81 so it's definitely less than 9. Now, we know it's between 8 and 9. try multiplying 8.5 x 8.5 = 72.25. So our ranges are
A) 64 - 72.25
B) 72.25 - 81.
74 falls between 72.25 - 81. So it'll be B
