Answer:
Total distance = 30.3 units
Step-by-step explanation:
Coordinates for the location of Alanah, Mia, Teresa and Arena are,
Alanah → (2, 8)
Mia → (8, 16)
Teresa → (8, 2)
Arena → (14, 4)
Distance between two points and is given by the formula,
d =
Distance between Alanah and Mia =
=
= 10 units
Distance between Mia and Teresa =
= 14 units
Distance between Teresa and Arena =
=
= 6.3 units
Total distance of Alanah's trip to Arena = 10 + 14 + 6.3
= 30.3 units
Answer:
Area = 72.62 m²
Step-by-step explanation:
Area of a triangle with the given three sides is given by,
Area =
Here, s =
And a, b, c are the sides of the triangle.
From the question,
a = 20 m, b = 10 m and c = 15 m
s =
s = 22.5
Substitute these values in the formula,
Area =
=
=
= 72.62 m²
Answer:
(b) There are 7 gallons left in the tank after 4 minuted
Step-by-step explanation:
Given
time since water began draining
gallons in the tank
Solving (a): Notation for gallons remaining at 4 minutes
This means that
becomes
Solving (b): Interpret f(4) = 7
We have:
time since water began draining
gallons in the tank
This means that:
It can be interpreted as:
There are 7 gallons left in the tank after 4 minuted
