Hello from MrBillDoesMath!
Answer: x^2 - 6.5x + 10.5 = 0
Discussion:
If the roots are 3 and 3.5, then the quadratic equation is
(x -3 ) ( x - 3.5) = 0
or
x * (x - 3.5) - 3 (x - 3.5) = 0
or
X^2 - 3.5X - 3X + 3(3.5) = 0
or
x^2 - 6.5x + 10.5 = 0
Thank you,
MrB
Answer; 47.27 Inches
Let the height of Dagne be x.
Now we are told that she can do a vertical jump that is 27.5% of her height. This is represented as 0.275x.
Now we are told the height she can jump is 13.2. Thus;
0.275x = 13.2
x = 13.2/0.275
x = 47.27 inches
Answer:
log 3(x+4) = log 3 + log (x+4)
Step-by-step explanation:
Because 3(x+4) is a product, log 3(x+4) = log 3 + log (x+4).
