3y = 0
y = 0
x = 7
Answer is C (7,0)
Answer:
the answer is "B"
the "a" (as in ax^2) is negative thus the parabola "goes downward"
Step-by-step explanation:
Answer:
area = 78.46
Step-by-step explanation:
31.4 = 2pi * r
divide 31.4 by 2 and get 15.7
15.7 = pi * r
divide 15.7 by pi and get
4.997 = r
(4.997^2) * pi = 78.46
The Set Up:
x² = (Side1)² + (Side2)² - 2[(Side1)(Side2)]
Solution:
cos(Toby's Angle) • x² = 55² + 65² - 2[(55)(65)] cos(110°)
x² = 3025 + 4225 -7150[cos(110°)]
x² = 7250 - 2445.44x =
√4804.56x = 69.31m
The distance, x, between two landmarks is 69.31m.
