What happened to a knight when they broke a promise?

Three part problem cant figure out the second and third parts (part 1 of 3) A cart loaded with bricks has a total mass of 12.9 kg and is pulled at constant speed by a rope. The rope is inclined at 20.6 ◦ above the horizontal and the cart moves 25.8 m on a...

During a workout, the football players ran up the stadium stairs in 59 s. The stairs are 140 m long and inclined at an angle of 40°. If a typical player has a mass of 103 kg, estimate the average power output on the way up. Ignore friction and air resista...

What is the algebraic expression for the uncertainty in the centripetal acceleration σac for uniform circular motion in terms of the uncertainties in the period and the radius of the motion? (Use the following as necessary: σT, σr, ac , T, and r.)

A bullet is shot into a block of plastic. The bullet penetrates the block 0.75 m. The mass of the bullet is 8 g. It is traveling with a speed of 410 m/s before it hits the block. A Use kinematic equations to find the magnitude of the acceleration on the b...

A tennis ball of mass m = 0.065 kg and speed v = 35 m/s strikes a wall at a 45° angle and rebounds with the same speed at 45° (see figure). What is the impulse given to the wall? Magnitude

A 0.060 kg tennis ball, moving with a speed of 7.00 m/s has a head-on collision with a 0.086 kg ball initially moving in the same direction at a speed of 3.10 m/s. Assume a perfectly elastic collision and take the initial direction of the balls as positiv...

Find the volume V of the described solid S. The base of S is a circular disk with radius 2r. Parallel cross-sections perpendicular to the base are squares.

Find the volume V of the described solid S. The base of S is an elliptical region with boundary curve 9x2 + 25y2 = 225. Cross-sections perpendicular to the x-axis are isosceles right triangles with hypotenuse in the base.

Two identical massless springs are hung from a horizontal support. A block of mass 3.2 kg is suspended from the pair of springs.The acceleration of gravity is 9.8 m/s^2. When the block is in equilibrium, each spring is stretched an additional 0.32 m.The f...

A factory that runs 24 hours a day, 7 days a week, has shifts for its workers that are 7 hours long. If a shift starts on Sunday morning at 6AM, at what time does the earliest shift on the next Friday start?

At the beginning of a trip, Gail's odometer reading was 100001 km. Gail filled the tank with 35L of gas. During the trip Gail bought 48L of gas, and at the end of the day filled the tank with 45.5L of gas. Gail was surprised to find at that time tat the o...

Well the answer to part one was 117.5 and do you have any idea about how to do part 2

Odds are the same as probability. The probability of a single event is what you want to happen over all possibilities. All possibilities = total number of students 10+15=25 Odds of choosing a girl 15/25=3/5 Odds of choosing a boy 10/25=2/5

If the value is a solution then it will make the statement true when it is substituted in. 3*2+4=10 10 is grater then 9 so 2 is a solution. To get a number that makes this false we can solve 3x+4=9. X=5/3

y=1/2(8x+4) 2y=8x+4 1/8(2y-4)=x

8k=2c-9d 8k-2c=-9d -8k+2c=9d (-8k+2c)/9=d if k=2c-(9d/8) k-2c=-9d/8 9d=8(k-2c) d=8(k-2c)/9

x=y+2 (y+2)^2+y^2=24 2y^2+4y+4=24 .5y^2+y=5 quadratic formula y=-1+sqrt(11),-1-sqrt(11) x=1+sqrt(11),1-sqrt(11)

slope=(-13--7)/4-2 =-3 -7=-3*2+b y intercept=-1 y=-3x-1

s(c)=c+(45/100)c

(65+49+24+15)/4=153/4 about 38.2500

s(c)=c+(45/100)c

y=slope*x+y intercept -2

42/5 about 8.400

x intercept occurs when y=0 solve -5x=-45 x intercept occurs at x=9 y intercept occurs when x=0 solve 9y=-45 y intercept occurs at y=-5

Volume of a sphere V=(4*Pi)/3*r^3 Domain all real numbers you can cube any real number and multiply it by another real number. This is a one to one cubic with an inverse. Solve for v in r=(4*Pi)/3*v^3 to find it. It is v= (1/4)* (3^1/3)*(4^2/3)*(r/Pi)^1/3

(15/100)s=5250 s=35000

u=x^2+1 du=2x dx integral of 1/2 1/u du=1/2*ln(x^2+1)

There are no natural even numbers that are prime except 2.

sqrt(x^2+2x-4)+c

(sqrt(3)/6)*arctan((sqrt(3)/2)*x) your welcome

c=(a^3+b^3)^1/3 b=(c^3-a^3)^1/3 a=(c^3-b^3)^1/3

no for first yes for second

probability is number of defective bulbs over total number of bulbs. 6% of 150 over 150. probability = 3/50

That's an aids answer. You just don't want to give an answer for us to copy off of you stupid head.

Bro, it takes five seconds to help this student out. Why can't you just research the answer and tell all of us. You're a jerk stupid head.

1) A- the placement of the Sun at the center of the solar system 2) A- stars are not a part of our solar system 3) A- The improve telescope showed scientists that the solar system contained comets. 4) A- the placement of the Sun at the center of the solar...
