Answer: ΔKE = 760.5 Joules

Step-by-step explanation:

Isnt the formula for ΔKE = 0.5m*v^2???

Im not going to use that formula you gave me, its wrong.

900/2 = 450

1.3^2 = 1.69

450 x 1.69 = 760.5 Jules

This is also the wrong subject btw

Y varies directly with x. If x = 16 and y = 2 find y when x = 96
ArbitrLikvidat [17]

Answer:

y = 12

Step-by-step explanation:

Use the equation y = kx

Plug in x and y to find k:

2 = k(16)

1/8 = k

Then, plug in 1/8 as k and 96 as x to find y:

y = 1/8(96)

y = 12

Write each equation in slope-intercept form<br> 2x-2y-12=0
Gnom [1K]

Answer: y=x-6

Step-by-step explanation:

2x-2y-12=0

1. Add 2y to both sides:

2x-12=2y

2. Divide both sides by 2

x-6=y

Arlecino [84]

Answer: 4x^2−4x+1

Step-by-step explanation:

(2x-1)^2

Square of Difference: (a−b)^​2=a^​2−2ab+b^2.

(2x)^​2−2*2x+1

Multiplication Distributive Property: (xy)^​a=x^{a} y^{a}

2^​​​2x^2−2*2x+1

4x^2−2*2x+1

4x^2−4x+1

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

A manufacture inspects 800 light bulbs and finds that 796 of them have no defects. What is the experimental probability that a l
BartSMP [9]

Answer:

The experimental probability that a light build chosen at random has no defects is 99.5 % or P(A)=0.995.

Step-by-step explanation:

let S be the sample space for the inspection of the light bulbs.

Therefore, n(s) = 800

let ' A ' be the event of no defects bulbs.

Therefore, n(A) = 796

Now the Experiment probability for a light bulb chosen has no defects will be given by,

P(A)=\dfrac{n(A)}{n(S)}

Substituting the values we get

P(A)=\dfrac{796}{800}=0.995

The experimental probability that a light build chosen at random has no defects is 99.5 % or P(A)=0.995.
