Answer:
2. The answer should be the last one.
3. The answer should be the first three.
Step-by-step explanation:
<u>Question 2</u>
KE = (1/2)mv²
2KE = mv²
v² = 2KE/m
v = ±√(2KE/m)
Therefore the answer should be the last one.
<u>Question 3</u>
b^(1/2) * b^(5/2)
Remember that the <u><em>product rule</em></u> states that b^x * b^y = b^(x+y)
So this means b^(1/2) * b^(5/2) = b^(1/2+5/2) = b^(6/2) = b^3
Also remember that the <u><em>power rule</em></u> states that √b = b^(1/2)
so this means b^(6/2) can also be written as (√b)^6
Therefore the answer should be the first three.
<em>If you want to double check all of your answers, just replace b with a number (for example, 2), and plug all of the choices into the calculator. Just </em><u><em>make sure</em></u><em> you are </em><u><em>very careful</em></u><em> when typing into the calculator.</em>
1 liter because 200 millimeters is 0.2 liter and 1.2 minus 0.2 equals 1 liter.

Answer:
El lote menor tendrá 1800 m^2
El lote mayor tendrá 2400 m^2
Step-by-step explanation:
Definamos las variables:
M = superficie del lote mayor
m = superficie del lote menor.
Sabemos que el terreno tiene en total 4200 m^2
Entonces:
M + m = 4200 m^2.
Y queremos que el lote menor sea 3/4 del lote mayor, entonces:
m = (3/4)*M
Podemos reemplazar esto en la ecuación de arriba para obtener:
M + ( (3/4)*M) = 4200 m^2.
Y ahora podemos resolver esto para M
M + (3/4)*M = 4200m^2
M*(1 + 3/4) = 4200m^2
M*(4/4 + 3/4) = 4200 m^2
M*(7/4) = 4200m^2
M = (4/7)*(4200m^2) = 2400m^2
Esto significa que la superficie del mayor lote es 2400 m^2
Y la superficie del menor se puede obtener con la ecuación:
m = (3/4)*M
m = (3/4)*2400m^2 = 1800m^2
La superficie del lote menor es 1800m^2
Answer:
y=2x+35
Step-by-step explanation:
so y is what it's equal too so you put y=
then since its $2 every mile you put them next to eachother like
2x so y=2x
then there is just a plain fee of $35 so you add that to the equation which is what makes it look like
y=2x+35
Hope this helps!! :D
