How many angle degrees does a minute hand travel in 1 minute? What angle does an hour hand travel in 1 min?

3 0

Answer:

The hour hand moves 360 degrees / 12 in an hour = 30 degrees.

It follows that in a minute it moves 30 degrees / 60 = 1/2 degree.

Therefore in a second it moves 1/2 degrees / 60 = 1/120 degree.

A car traveled 180 miles at a constant rate.
cestrela7 [59]

Answer/Step-by-step explanation:

A. Distance travelled at constant rate = 180 miles

Rate of travel (r) = distance travelled (d) /time (t)

Travel time (hrs) ==> rate of travel (miles/hr)

5 ==> 180/5 = 36

4.5 ==> 180/4.5 = 40

3 ==> 180/3 = 60

2.25 ==> 180/2.25 = 80

B. t = time travelled in hrs,

r = rate (miles/hr)

d = distance travelled = 180

Therefore, rate travelled for t hours would be:

r = \frac{180}{t}

if f(x) = ax^6 + bx^4 + cx^3 where a,b, and c are integers, how many distinct rational zeros could f(x) have
natita [175]

You can rewrite your function as

f(x) = x^3(ax^3+bx+c)

This implies that

f(x)=0 \iff x^3=0\quad\lor\quad ax^3+bx+c=0

Now, we have x^3=0\iff x=0, so it counts as a solution.

On the other hand, depending on the coefficient a, b and c, the cubic equation

ax^2+bx+c=0

can have either one or three solutions.

So, we have the solution x=0, and then one or three solutions coming from the cubic part. The equation as a whole thus have either two or four solutions, depending on the coefficients.
