Answer:
Scalene triangle
Step-by-step explanation:
-Given that Grace's triangle has 3 different dimensions for all the 3 sides, it is a Scalene triangle.
-A scalene triangle has different measurements for all of its three dimensions.
-Scalene triangles have different measurements for all of its 3 angles.
Work shown above! The zeroes are 3, -8, and 11
Answer: 2
Step-by-step explanation:
The circumference of a circle is 2*radius*pi.
We can set up an equation as we know the circumference as 4pi.
4pi = 2*radius*pi
Divide both sides by pi:
4 = 2*radius
Divide both sides by 2:
radius = 2
Answer:
Below.
Step-by-step explanation:
a. Φ^2 − Φ − 1 = 0
Φ2 − Φ = 1
(Φ - 0.5)^2 - 0.25 = 1
(Φ - 0.5)^2 = 1.25
Φ - 0.5 = √(1.25) (We only take the positive root).
Φ = 0.5 + √(1.25)
b. I used Completing the square.
c. Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.
