This is because there is an imaginary 1 in front of the first sqrt.
Answer:
- 1/64 (x+4)² (x-3) (x-4) = 0
Step-by-step explanation:
f(x) = a (x+4)²(x-3)(x-4) ... curve touch (-4,0) and not cross x axis
x=0 f(x) = -3
a (4)² * (-3) * (-4) = -3
a = - 1/64
- 1/64 (x+4)² (x-3) (x-4) = 0
Answer:

Step-by-step explanation:
1. Approach
First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is,
. Next, find the area of the room by multiplying the length by the width.
2. Convert the unit of measurement
The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is,
.

3. Find the area of the room
Now multiply the length by the width to find the area of the room.

Answer:
D
Step-by-step explanation:
Take 10% of the snowboard price.
10% = 0.1
109 * 0.1 = $10.90 (10% discount)
109 - 10.9 = $98.10 (Price with discount).
Take 12% of the new snowboard price.
12% = 0.12
98.1 * 0.12 = 11.772 (Round to 11.77)
98.10 - 11.77 = $86.33 (Final discounted price)
Take 6% tax on the new snowboard price.
6% = 0.06
86.33 * 0.06 = 5.1798 (Round to 5.18)
86.33 + 5.18 = $91.51
