Answer:
D. 
Step-by-step explanation:
Area of sector of a circle is given as θ/360*πr²
Where,
r = radius = 12 cm
θ = 56°
Use 3.14 as π
Plug in the values into the formula and solve


Area of the sector ABC =
The answer is D
= (3/8) (16x + - 24)
=(3/8) (16x) +(3/8)(-24)
=6x - 9
Answer:
The answer is 3rd option.
Step-by-step explanation:
In a graph, domain is always represented by the x-axis. So by looking at the graph, the minimum value of x is -2. We can know that x ≥ -2.
The time that taken for the two trains is 1.2 hours.
The computation of the time taken for the two trains is shown below:
Given that
The westbound train travels 55 miles per hour.
And, the eastbound train travels 75 miles per hour.
So, the total speed is
= 55 miles per hour + 75 miles per hour
= 130 miles per hour
The distance is 156 miles
So, the time taken is

= 1.2 hours
Therefore we can conclude that the time that taken for the two trains is 1.2 hours.

ANSWER

EXPLANATION
We were given that

varies directly as

We can write this mathematically as,

This implies that,

where k is the constant of variation.

This implies that,


The equation becomes

When
