Answer:
Option B.
Step-by-step explanation:
Note: Given roots are not in proper format.
Consider the polynomial function f(x) has roots 0, 3, and .
According to irrational root theorem if is root of a polynomial P(x), then
is also a root of polynomial P(x).
Since is an irrational root of the function f(x). By irrational root theorem
is also a root of function f(x).
Therefore, the correct option is B.
Number of people can hold in each car = 10
Solution:
Number of cars in the Blazing Bullet = 6
Total number of people can ride at one time = 60
Number of people can hold at one Bullet car = ?
Let n be the number of people in each car can hold.
Now write a equation to find the number of people in each car.
Number of cars × number of people in each car = Total number of people
⇒ 6 × n = 60
⇒ 6n = 60
Now, solving this equation.
⇒ 6n = 60
Divide both sides of the equation by 6.
⇒ n = 10
Hence 10 people can hold in each car.
Given:
radius of cone = r
height of cone = h
radius of cylinder = r
height of cylinder = h
slant height of cone = l
Solution
The lateral area (A) of a cone can be found using the formula:
where r is the radius and l is the slant height
The lateral area (A) of a cylinder can be found using the formula:
The ratio of the lateral area of the cone to the lateral area of the cylinder is:
Canceling out, we have:
Hence the Answer is option B
