(Advanced mathematic) A particle moves in a straight line from a fixed point O. The displacement is s in meter is
C3
given = 4 + 52 − 10 where t is the time in seconds after passing O. Find the velocity and acceleration of particle at 3 seconds .
Suatu zarah bergerak dalam garis lurus dari titik tetap O. Sesaran adalah diberi dalam s, meter dengan persamaan by = 4 + 52 − 10 di mana t ialah masa dalam saat selepas melalui O. Cari halaju dan pecutan zarah tersebut pada 3 saat.

its 4 because 2 times 2 is 4, if you double the number two you get four

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
