Hello,
f(x)=2x^3-x^2-4x+9=(((0+2)x-1)x-4)x+9
f(3)=(((0+2)*3-1)*3-4)*3+9=((2*3-1)*3-4)-3+9=(5*3-4)*3+9=11*3+9=33+9=42
or
f(3)=2*3^3-3^2-4*3+9=2*27-9-12+9=54-12=42
You need to find the root of 69 since the length and width are multiplied to get the area, therefore it would be 8.3 inches.
Answer:
94.86 miles per hour
Step-by-step explanation:
The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)
The appropriate customary unit is calculated as:
1 km = 0.62 miles
153 km = x
Cross Multiply
x = 153 × 0.62 miles
94.86 miles
Therefore, the appropriate customary unit is 94.86 miles per hour
