A wheel of radius 10 cm is turning at a rate of 5 revolutions Calculate: the distance moved by a point on the rim in 2 seconds

Answers

Answer 1

Answer:

15°

Step-by-step explanation:

Angular velocity= 5rev/ min

= 10π/ min

But 1 min= 60 secs

= Angle turned/ 2secs

= 10π/(60×2)

= π/12 × 180/π= 15°

How many metres in 4 and half kilometres

Answers

there are 4500 meters because 1 kilometer is equal to 1000meters

I need to find how many solutions does the system have.

Answers

From what I got there is one real solution :)

Rearrange the second equation to give y=2-2x, substitute into the first equation to give you a value for x and then using that you can work out y for the exact coordinates of intersection :)

Also they are both straight line graphs so they will either have one or no solutions

Hope this helped :)

tom sold half of his comic books and then bought six more. he now has 12. how many did he begin with?

Answers

b=books
Sold half of book: b/2
Bought six more: b/2+
Now has 12: b/2+6=12
Subtract 6 on both sides: b/2+6-6=12-6
b/2=6
Multiply both sides by 2: b=12
Answer= 12 books

E.J. has shown that a function, f(x), grows by 12% for every unit in the domain. What does this prove?The function f(x) is an arithmetic sequence.
The function f(x) is a geometric sequence.
The function f(x) is not a sequence.
This does not prove anything.

Answers

Answer:

B. The function f(x) is a geometric sequence.

Step-by-step explanation:

We are given that,

The function f(x) grows by 12% for every unit in the domain.

That is,

For the initial value, let the output value be x.

For the next value, the output will be $0.12x$

For the next value, the output will be $0.12* 0.12x=(0.12)^2x$

For the next value, the output will be $(0.12)^3x$ and so on..

Thus, the output values are increasing by the rate $((0.12)^2)/(0.12)=0.12$

Hence, the function f(x) represents a geometric sequence.

The answer is B I just took the test

Bryan plays on the high school basketball team. In his first ten games he scored 12, 14, 8, 9, 8, 16, 8, 13, 22, and 19 points. Choose and calculate the best measure of central tendency to represent Bryan's scoring over the first ten games. Justify your choice.

Answers

The best tendency is the "middle" or "most common" value, so basically it's either the mean or the mode- in this case we use the mode and we can see 12,14,8,9,8, 13, 22 ,19 so 8,8,9,12,13,14,18,22 ; the answer is 13
