To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.
•
yields 2 real roots
•
yields 1 real root
• [tx]b^2-4ac<0[/tex] yields no real roots
where a=4, b=-7, and c=2
.
It has 2 real roots
Answer:
Step-by-step explanation:
11x - 2° = 75° ( being corresponding angles )

Answer:
8 rotation will the tires made after frank rides 50 ft.
Step-by-step explanation:
Given: The tire on franks bike moves 75 inches in one rotation.
If bike of tire move 75 in then rotation of wheel is 1
In 75 in of tire move = 1 rotation
In 1 in of tire move =
rotation
Now we change 50 ft into inches
1 ft = 12 inches
50 ft = 12 x 50 = 600 inches
In 1 inch of tire move =
rotation
In 600 inch of tire move =
rotation
Hence, 8 rotation will the tires made after frank rides 50 ft.
