Super size gives you the best price per ounce
Answer:
19
Step-by-step explanation:
When 2 chords intersect then the product of the parts of one chord equal the product of the parts of the other chord, that is
12(x - 7) = 4(x + 3) ← distribute parenthesis on both sides
12x - 84 = 4x + 12 ( subtract 4x from both sides )_
8x - 84 = 12 ( add 84 to both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus
12 + x - 7 = 12 + 12 - 7 = 17
4 + x + 3 = 4 + 12 + 3 = 19 ← longer chord
Answer:
The resistance is decreasing at a rate of 0.36 ohms/minute.
Step-by-step explanation:
The mathematical form of the Ohm's law is given by :
V = IR ...(1)
Where V is voltage, I is current and R is resistance
Given,
I = 5 A
R = 6 ohms
dI/dt = 0.3 A/min
Differentiate equation (1) wrt t:
When V is constant, dV/dt = 0
So, the resistance is decreasing at a rate of 0.36 ohms/minute.
Answer:
2 parallel lines will have the same slope. y = mx + c is the general form of the slope-intercept formula of a line, the slope is given by m.
Subtract 3x from
both sides: −2y = −3x + 16; divide
both sides by −2: y x = − 3
2 8.
