Kinetic Energy = (1/2)mv².

where m = mass in kg= 2.5 * 10⁵kg = 250000 kg, v = velocity in m/s = 3*10² m/s = 300 m/s

Kinetic Energy = (1/2)*250000*300² = 0.5 * 250000 * 300 * 300

                         = 1.125 × 10¹⁰  Joules.


2)  Relationship between aⁿ and a⁻ⁿ   

a⁻ⁿ  =   1 / aⁿ

or

aⁿ  =   1 / a⁻ⁿ

What is the answer to this problem? 7(g+5)=105
Liono4ka [1.6K]

Answer:

g = 10

Step-by-step explanation:

Distribute 7 to the parentheses:

7(g + 5) = 105

7g + 35 = 105

Solve for g:

7g + 35 = 105

7g = 170

g = 10

So, the answer is g = 10

The length of a rectangle is (6x2 + 3x - 2) units, and its width is (x3 - 2x + 5) units. Part A: What is the area of the rectang
strojnjashka [21]
<span>Part A: Area = length * width = (6x^2 + 3x - 2) * (x^3 - 2x + 5) Multiply it out and simplify.

part B: </span><span>Take the first term 6x^2 and multiply each of the term x^3, -2x & 5. Then take 3x and multiply each of the term x^3, -2x & 5. Do the same with -2. Then add like terms and simplify.</span>

In the figure points A B C D and E are collinear. If AE = 38 and BD = 15
fredd [130]

Answer:

D. 30.5

Step-by-step explanation:

Given that A, B, C, D, and E are collinear,

AE = 38,

BD = 15, since segment BC = CD = DE, therefore

BD = ⅔ of BE

15 = ⅔*BE (substitution)

Solve for BE

Multiply each side by 3

15*3 = ⅔*BE*3

45 = 2*BE

Divide both sides by 2

45/2 = BE

22.5 = BE

BE = 22.5

Find AB:

AB + BE = AE (segment addition postulate)

AB + 22.5 = 38 (Substitution)

AB = 38 - 22.5 (Subtracting 22.5 from each side)

AB = 15.5

Find length of segment AD:

AB + BD = AD (segment addition postulate)

15.5 + 15 = AD (Substitution)

30.5 = AD

AD = 30.5
