Answer: Option A
Step-by-step explanation:
In the graph we have a piecewise function composed of a parabola and a line.
The parabola has the vertex in the point (0, 2) and cuts the y-axis in y = 2.
The equation of this parabola is 
Then we have an equation line
Note that the interval in which the parabola is defined is from -∞ to x = 1. Note that the parabola does not include the point x = 1 because it is marked with an empty circle " о ."
(this is 
)
Then the equation of the line goes from x = 1 to ∞ . In this case, the line includes x = 1 because the point at the end of the line is represented by a full circle
.
(this is 
)
Then the function is:
Answer:
The correct answer is 9 m per 
Step-by-step explanation:
Force is defined by mass of an object times it's acceleration.
Let the mass of the object be m kilograms.
When a force of 30 N acts on a certain object the acceleration of the object is 5 m per
∴ 30 = m × 5
⇒ m = 6.
If the force is changed to 54 N, let the acceleration of the object be x m per .
∴ 54 = m × x
⇒ x = 
= 9
Thus when the force is 54 N, the acceleration of the object is 9 m per .
10(3) + 3 = 33 times in 2 minutes
10(120) + 3 = 1203 times in 2 hours
Answer:
15 years old
Step-by-step explanation:
im assuming they're saying to find Ankit's age if his father is 50.
Ankit's father=f, Ankit=a
f=3a +5, f=50: 50=3a+5 -> 3a=45 -> a=15
