Answer:
3.5 
Step-by-step explanation:
If the shape is half of a circle, you will be using this formula: A = 
π 
Your radius is half of the diameter. r = d/2 = 3/2 = 1.5
Substitute r = 1.5 into the formula.
A = π 
A = (3.14)
Use your calculator to find the answer and round your answer.
3.5
X^3 + 7*x^2 + -16*x-112
=(x + 4)*(x + 7)*(x - 4)
Y = mx + c
-4 = 2(3) + c
-4 = 6 + c
-10 = c
y = mx + c
y = 2x - 10
Hence, the equation is y=2x-10.
Answer:
Mina took 2,986 steps on the third hour.
Step-by-step explanation:
With the information provided, you know that Mina took a total of 9,245 steps in three hours and as you know the quantity of steps she took on the first and second hour, you can subtract the steps she took on the first and second hour from the total amount of steps to determine the steps she took on the third hour:
9,245-2,387-3,872=2,986
According to this, the answer is that Mina took 2,986 steps on the third hour.
