When an object moves on a circular path, the centripetal force varies directly as the square of the velocity and inversely as the radius of the curve. If the force is 640 lb for a velocity of 20 mi/h and radius of 5 m, find the radius for a velocity of 30 mi/h and a force of 1800 lb.
Answers
Answer: I think it's 40
Step-by-step explanation:
I don't know, I just need points. If you take the 640 and divide it by the nearest angular velocity, then square it, then divide by the radius, you get Bolivia

Table A c. Table C b. Table B d. Table D
Answers
Answer:
the answer is c
Step-by-step explanation:
We can see that Table A best illustrates the values for the equation.
The answer is (a) Table A.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The given equation is y = x² + 7x.
We can determine the values of a, b, and c by comparing the equation to the standard form of a quadratic equation,
which is y = ax² + bx + c.
In this case,
a = 1, b = 7, and c = 0.
To determine the direction in which the parabola opens, we can look at the coefficient of the x² term, which is a.
Since a is positive, the parabola opens upwards.
The y-intercept is the point where the parabola intersects the y-axis.
To find it, we can set x = 0 in the equation:
y = 0² + 7(0) = 0
So the y-intercept is (0,0).
Thus,
We can see that Table A best illustrates the values for the equation.
The answer is (a) Table A.

What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We are given that bedroom and office in the diagrams below are similar rectangles.
It is given that the walls on the left sides in the diagram are proportional, and the walls on the top sides in the diagram are proportional.
Threfore, we get;
x/10 = 14 /12
Solving;
x = 14/12 (10)
x = 16.8
Hence, the value of the missing wall x is 16.8 feet.

A red die and a blue die are rolled. You win or lose money depending on the sum of the values of the two dice. If the sum is 6 or 10, you win $4. If the sum is 5, 9, or 12, you win $1. If the sum is any other value (2, 3, 4, 7, 8, or 11), you lose $2. Let X be a random variable that corresponds to your net winnings in dollars. What is the expected value of X
Answers
Answer:
The expected value of X is $0.0833.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
For each dice, there are 6 possible outcomes(values from 1 to 6). So for 2 dices, there are [tex]6^2 = 36[/tex] desired outcomes.
Desired outcomes:
Sum 5: (1,4), (2,3), (3,2), (4,1).
Sum 6: (1,5),(2,4),(3,3),(4,2),(5,1)
Sum of 9: (3,6), (4,5), (5,4), (6,3)
Sum of 10: (4,6), (5,5), (6,4)
Sum of 12: (6,6)
Probabilities:
5 + 3 = 8 outcomes in which the sum is 6 or 10, that is, 8/36 probability of winning $4.
4 + 4 + 1 = 9 outcomes in which the 5, 9, or 12, that is, 9/36 probability of winning $1.
36 - (8 + 9) = 36 - 17 = 19 remaining outcomes, that is, 19/36 probability of losing $2.
What is the expected value of X?
Multiplication of each outcome by its probability. So
[tex]E(X) = \frac{8}{36}*4 + \frac{9}{36}*1 - \frac{19}{36}*2 = \frac{8*4 + 9*1 - 19*2}{36} = \frac{32 + 9 - 38}{36} = \frac{3}{36} = 0.0833[/tex]
The expected value of X is $0.0833.
