Please answer this fast. This was due October 6th and I need to get it done!!!!! The energy E of a moving object is called its
kinetic energy. It is calculated using the formula E = { mv2,
where m is the object's mass in kilograms and v is its
speed in meters per second. The units of kinetic energy are
kilograms - meters
abbreviated as kg • m²/s2.

• then let's make m the subject:
[tex]{ \rm{E = \frac{1}{2}m {v}^{2} }} \\ \\ { \rm{m {v}^{2} = 2E }} \\ \\ { { \green{ \boxed{ \boxed{ \bf{m = \frac{2E}{ {v}^{2} } }}}}}} \\ [/tex]
Answer: m = 2E/v²
Question b:

You have $6 to spend on lunch. The drinks cost $1.25 each and the salad
costs $0.20 per ounce. Write an equation in standard form that models
this situation.
1. 1.25 +.20x = 6
2. 1.25x + 20y = 6
3. 1.45x = 6
4. 1.25x + 6y = 20
Answers
Answer:
1. 1.25 + .20x = 6
Step-by-step explanation:
You will most likely just buy one drink and multiple ounces of salad with the 6 dollars you have to purchase a whole meal.
.20x, where x equals how many ounces you purchase
1.125 for the one drink
When set equal to 6 dollars you are able to find how much salad plus a drink you can purchase in total.
If x and y are real numbers such that x > 0 and y < 0, then
which of the following inequalities must be true? (Hint:
plug in possible numbers for x and y)
Answers
Answer:
Step-by-step explanation:
The third one
If x and y are real numbers such that x > 0 and y < 0, then |x|^2 >|y| could be the correct option. So Option 3 is answer.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms then there might be some values of those variables for which that equation or inequality might be true.
Such values are called solution to that equation or inequality.
So, Set of such values is called solution set to the considered equation or inequality.
If x and y are real numbers such that x > 0 and y < 0,
We need to find the inequalities that must be true for the given situation;
Hence, |x|^2 >|y| could be the correct option.
When we put a number such that x > 0 and y < 0, then this holds true.
So Option 3 is answer.

Answers
Answer: No, it is not a unit rate
Explanation:
A unit rate is when the time value in the denominator is 1. So it would need to be "1 day" instead of "5 days" for it to be a unit rate. The term "unit" means "one".
To convert to a unit rate, we simply compute 1/5 = 0.20 to see that the unit rate is 0.20 books per day. This is the same as saying "0.20 books every 1 day", but I think the phrasing "books per day" is more common.

Answer:
m∠LON = m∠HKJ
Step-by-step explanation:
. m∠LOM = m∠JKI; m∠MON = m∠IKH 1.
2. m∠LOM + m∠MON = m∠JKI + 2.
m∠MON
3. m∠LOM + m∠MON = m∠JKI + 3.
m∠IKH
4. m∠LOM + m∠MON = m∠LON; 4.
m∠JKI + m∠IKH = m∠HKJ

Calcula la suma de las longitudes de los catetos, si la hipotenusa mide 15 u y la altura relativa a ella mide 6 u.
UwU
Answers
Answer:
9 sqrt(5)
Step-by-step explanation:
La altura relativa a la hipotenusa corta la hipotenusa en dos segmentos.
Defina x como
x = la longitud de uno de esos segmentos
Entonces, la longitud del otro segmento = 15 - x.
Entonces, por el teorema, tenemos que (15-x) (x) = 36, de modo que
15x - x ^ 2 = 36
x ^ 2 - 15x + 36 = 0
(x-3) (x-12) = 0
Entonces, x = 3 o x = 12.
Sin pérdida de generalidad. sea x = 3.
Entonces, la suma de las dos piernas es
raíz cuadrada (6 ^ 2 + 3 ^ 2) + raíz cuadrada (12 ^ 2 + 6 ^ 2) =
raíz cuadrada (36 + 9) + raíz cuadrada (144 + 36) =
raíz cuadrada (45) + raíz cuadrada (180) =
raíz cuadrada (9 * 5) + raíz cuadrada (36 * 5) =
3 raíz cuadrada (5) + 6 raíz cuadrada (5) =
