We have 12 8-ounce bottles, so altogether we have 12 * 8 = 96 ounces of bottled water. If it all costs $3.36, than one ounce of bottled water costs $3.36 / 96 = $0,035.
Answer:
points G and I have coordinates (6,4) and (3,2)
Use Pythagorean theorem to calculate the straight line distance between points G and I
points G and I have coordinates (6,4) and (3,2)
Draw a line parallel to y axis passing through G
Draw a line parallel to x axis passing through I
Intersection point K ( 6 , 2)
IK = 6 - 3 = 3
GK = 4 -2 = 2
ΔIKG right angled triangle
Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.
GI² = IK² + GK²
=> GI² = 3² + 2²
=> GI² = 13
=> GI = √13
using distance formula
G (6,4) and I (3,2)
= √(6 - 3)² + (4 - 2)²
= √3² + 2²
= √9 + 4
= √13

Answer:
15.
Step-by-step explanation:
Please consider the complete question.
You have to answer 2 essay questions for an exam. There are 6 essays to choose from. How many different groups of 2 essays could you possibly choose?
We will use combinations formula to solve our given problem.
The number of combination of n terms r terms chosen at a time is given by formula:
Therefore, there are 15 different groups of essays could you possibly choose.
Using the law of sines, we have
And we know that
So, the equation becomes
F(6) = 6(5 - 6) = 6(-1) = -6
f(6.1) = 6.1(5 - 6.1) = 6.1(-1.1) = -6.71
f'(6) ≈ (-6.71 - (-6))/(6.1 - 6) = -0.71/0.1 = -7.1
