24; 240/10 = 24
The answer is 24
Answer:
The roots of the function are x = -5/3 and 3. Select these.
Step-by-step explanation:
The roots of the function are the solutions to the function. They are also called the x-intercepts or zeros. To find them, factor the function completely and solve using the zero product property.
f(x) = (3x+5)(x2-6x+9)2 becomes f(x) = (3x+5)(x-3)^2
Set each factor equal to 0 and solve for x.
(3x+5)=0
3x = -5
x = -5/3
(x-3)^2 = 0
x - 3=0
x = 3
Answer:3
Step-by-step explanation:
cause 15-3-3-3-3-3 has 5 3's
Total distance between the trains = 348 miles
Total time to cross that distance by trains = 3 h.
So, sum of their speed would be: 348/3 = 116
A.T.Q,
Speed of train 1 - speed of train 2 = 22
so, two equation that has formed are:
a+b=116
a-b=22, a=b+22
Substitute that in above equation; b+22+b=116
2b= 94, b=47 & a=116-47 =69
Speed of the TRAIN IS 47 & 69 miles per hour.
