Answer:
2.35 yards/second or 7.07 ft/second
Step-by-step explanation:
The distance to be covered is 55 yards.
The casting cools at the rate of 
and the temperature must not be allowed to cool more than 
.
We know that, 
By the time, the temperature reaches , it will take about,
, so it will take about 23.33 seconds.
Also, 55 yards = 
So the minimum speed that conveyor must move is,
Hence, the speed of conveyor is 7.07 feet per second.
The circumference is 24 because the radius is half of the circumstance so 12 times 2 would be 24
Answer:
Step-by-step explanation:
so he gets a 12% commission on his sales. He sold a slide that costs 270.
so he would get 12% of 270
turn ur percent to a decimal..." of " means multiply
0.12 * 270 = $ 32.40 <===
Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1
