Answer:
multiply 10 x 17
multiply 24 x 7
if they are the same answer, it is a proper proportion.
Step-by-step explanation:
Two of the side lengths and one of the angles of both of the triangles. Hope this helps!
Step-by-step explanation:
the first is
2(x - 1/2)² = 2(x² - 2×1/2×x + 1/4) = 2x² - 2x + 1/2
so, no, this is not the same.
the second is
2(x - 1/4)² = 2(x² - 2×1/4×x + 1/16) = 2x² - x + 1/8
that is the correct answer.
the third is
2(x - 1/8)² = 2(x² - 2×1/8×x + 1/64) = 2x² - 1/2 x + 1/32
so, no, this is not the same.
the fourth is
2(x - 1/16)² = 2(x² - 2×1/16×x + 1/256) = 2x² - 1/4 x + 1/128
so, no, this is not the same.
Answer:
5 ft
Step-by-step explanation:
a square has all equal sides
In one day, there are 24 hours. In 1 hour, there are 3,600 seconds. So, that means that there are 86,400 seconds. Also, in 1 day, the short hand which denotes the number of hours, makes 2 revolutions around the clock. Its distance traveled would be twice the perimeter of the circle.
Distance traveled by hour hand = 2(2πr) = 4πr₁
In 60 s, the long hand, which denotes numbers of minutes, makes one revolution around the clock. Since there are 86,400 seconds in a day, that would be a total of 1,440 revolutions.
Distance traveled by minute hand = 1,440(2πr) = 2,880πr₂
Difference = 2880πr₂ - 4πr₁ = 4π(720r₂ - r₁), where r₁ is the length of hour hand and r₂ is the length of minute hand.
