The energy is compared based on the information given below.

<h3>How to illustrate the energy?</h3>

Energy released by burning 1 kilogram of element A = EA = 5.1 * (10)8

Energy released by fission of hydrogen in 1 kilogram of element B = EB = 1.3 * (10)10

Therefore,

Ratio = EB / EA = 1.3 * (10)10 / 5.1 * (10)8 = 25

Thus, the fission of 1 kg of element B releases 25 times as much energy as burning 1 kilogram of element A.

What is the slope of the line defined by the parametric equations x=-2+4t and y=1+4t ?

LekaFEV [45]

Answer:

The value of slope m = -1

Step-by-step explanation:

x = -2 + 4t

and y = 1 + 4t

Solving the both equations

x +2 = 4t

=> t = (x+2)/4 eq(1)

y-1 = 4t

=> t = (y-1)/4 eq(2)

Putting eq(1) = eq(2) as left hand side of both equations are same

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

Cross multiplying

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

4x + 8 = 4y -4

4x +4y = -4 -8

4x + 4y = -12

4(x+y) = -12

x+y = -12/4

x+y = -3

y = -x -3

The slope intercept form of line is:

y = mx + b

where m is the slope. Comparing with y = -x-3

The value of slope m = -1

The cost of four sweats and two pairs of jeans is $140. The cost of two sweats and theee pairs of jeans is $150. Define the vari

posledela

Answer:

The system would be:

4x + 2y = 140

2x + 3y = 150

Step-by-step explanation:

If we represent the cost of sweats by the letter x and the jeans by the letter y, we can then write an equation for each of the situations using the number of each in each situation.

4x + 2y = 140

2x + 3y = 150

without using your calculator or computer graphing tool. match each function rule with its graph. In each case, write a sentence

valentinak56 [21]

Well I know that c. goes with I. just because I saw so many x^3 graphs.

For a. the parent function is x^2, so 0.5x^2 should look about the same as x^2, so the answer is VI.

A baseball team consists of 2 stars, 13 starters, and 10 substitutes. For tax purposes, the team owner must value the players. T

inessss [21]

Answer:

The total value of the team=$8.2 million

Step-by-step explanation:

Step 1

Determine the total value of the team as follows;

V=(S×s)+(T×t)+(B×b)

where;

V=total value of the team

S=total value per star player

s=number of stars in the team

T=total value per starter

t=number of starters in the team

B=total value per substitute

b=number of substitutes in the team

In our case;

S=1 million per year

s=2 stars

T=400,000

t=13

B=100,000

b=10

replacing;

V=(1,000,000×2)+(400,000×13)+(100,000×10)

V=(2,000,000+5,200,000+1,000,000)

V=8,200,000=8.2 million

The total value of the team=$8.2 million
