Answer:
8+(-2)=6
Step-by-step explanation:
For this case we have the following equation:
f (x) = x ^ 2 + bx-49
Deriving we have:
f '(x) = 2x + b
We match zero:
0 = 2x + b
We clear x:
x = -b / 2
The axis of symmetry is at x = 8, therefore:
x = -b / 2 = 8
Clearing b:
b = -2 * (8)
b = -16
Answer:
the value of b is:
b = -16
So a deckameter is = to 10 meters
just multiply it
3*10= 30
then divide
30/1= 30
So glenn needs 30 meter paces of ribbon
Answer:idk but good luck. Hope you find your answer
Step-by-step explanation:
The population density in the United States is D = 92.1 people/mi^2
<h3>
</h3><h3>
How to get the population density?</h3>
To get the population density, we need to take the quotient between the total number of people and the area.
In this case, we know that the total population is 325.7 million, and the area of the United States is 3,535,932 mi^2
Then the population density:
D = (325.7 million)/( 3,535,932 mi^2) = 9.21*10⁻⁵ million/mi^2
And we know that 1 million = 1,000,000 = 1*10⁶
Then:
9.21*10⁻⁵ million/mi^2 = 9.21*10¹ people/mi^2 = 92.1 people/mi^2
This means that in each square mile in the United States, there are around 92.1 people.
