ABC is an isosceles triangle where AB = AC and BC = 60. D is a point on BC such that the perpendicular distance from D to AB and AC is 16 and 32, respectively. What is the length of AB?
A cargo plane is moving with a horizontal velocity of vx = +225 m/s at a height of y = 920 m above level ground as shown in the figure below when it releases a package. Ignoring air resistance, how much time will it take the package to reach the ground? (Express your answer to...
8x+7=6 (subtract the 7 from left side) 8x=-1 (divide the 8 on both sibes) x= (-1/8)
YOU HAVE TO CHECK If Alice now applies QFT2n and measure, she will still get k with probability 99%. AND If she does as in the previous option, she will get k with probability 99%.
I think it should be x<=5/6 1. multiply thru by 5.... 2x-15x+10>=5x-5 2. combine like terms... -13x+10>=5x-5 3. get your variables on one side(-5x from both sides) -18x+10>= -5 4. isolate the variable... (-10..) -18x>=-15 5. /both sides by -18 !!careful!! whenev...
It's a proportion...53/63=x/67 in other words... st.height/st.shadow=tr.height/tr.shadow Solve by cross multiplying...63x=53*67 so x=56.37inches.. Good Luck!
Consider a pair of parallel plates with a potential difference of 12 V and are separated by 12 cm. What is the potential energy of a 1.0 C charge at point A, exactly 30. cm from each plate?
