6. 40 minutes (15/3 = 5 minutes/mile) - 5*8 = 40 min
7. 15,840 ft / 5 = 3.168 ft
Answer:
the length of the missing side is 2
Step-by-step explanation:
Use a^2 + b^2 = c^2
a = 4
b = ?
c = 2sqrt5
4^2 + b^2 = (2sqrt5)^2
16 + b^2 = 20
subtract 16 from both sides
b^2 = 4
take the sqrt of both sides
b = 2
Answer:
what does it pass through
Consider this option:
1.the equation of the circle using its centre and point (0;-4) is:
x²+y²=4.
2. to substitute given point (23;2) into the equation of the circle:
23²+2²≠4
answer: this point does not belongs to the circle.
