-9,4
Step-by-step explanation:
Answer:
14,1 cm
Step-by-step explanation:
If a circle passes through the vertices of a square then the diagonal of a square is a circle diameter.
We use Pytagoras Theorem to find out the length (L) of the diagonal given that:
L² = (20)² + (20)²
L² = 2* (20)²
L = √2 * 20
L = 1,4142* 20
L = 28,28 cm
L diagonal in the square is a diameter of the circle then radius of a circle is:
r = L/2 ⇒ r = 28,28 /2 ⇒ r = 14,14 cm
Divide the second price by the second pounds. 9.95 / 5 = 1.99
So for every pound you get you pay 1.99 dollars. The second deal is better.
Answer:
A-2, B-5, C-1, D-6, E-3, F-4
Step-by-step explanation:
The A would be the function x^3, so it would be the volume of a cube which is #2
B is probably the temperature graph, because it is warmest in the middle of the day and cooler at both ends, so that is #5
C is probably the age of an oak tree because it starts at 0, and grows linearly. #1
E is #3 because it is decreasing and so is the fuel in the tank.
F is the area of a triangle one, because that would be a quadratic function (half of a parabola)#4
D is the car wash, it doesn't start at 0 because the x-axis is the time of day. #6
