If anything there might be an eraser icon (modification notes) so you might want to click on that and read it. If not, post what it says or give the math teacher a call. I hope this helps!

Larry claims that (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are equivalent because they have the same digits and the same op

FromTheMoon [43]

Answer:

$(14+12)\times (8+12) > (14\times 12)+(8\times 12)$

Step-by-step explanation:

First let us evaluate the value of both the expressions.

$(14+12)\times (8+12) = 26\times 20 = 520$

$(14\times 12)+(8\times 12) = 168 + 96 = 264$

a) Hence, Larry's claim that both the expressions are equivalent is wrong.

The evaluation of the expressions have been shown above. The second expression was obtained by swapping the addition and multiplication order and that created the difference.

b) Clearly,

520 > 264

Therefore,

$(14+12)\times (8+12) > (14\times 12)+(8\times 12)$

$(14+12)\times (8+12)$ is greater by the expression $(14\times 12)+(8\times 12)$ by a value of 520 - 264 = 256.

The formula to find the period of orbit of a satellite around a planet is T^2=(4pi^2/GM)r^3 where r is the orbit's mean radius,

Natalija [7]

The answer is $r= \sqrt[3]{GMT^{2}/4 \pi^{2}}$

$T^{2} = \frac{4 \pi^{2}}{GM} r^{3}$

Move $\frac{4 \pi^{2} }{GM}$ to the other side of the equation:
$T^{2} /\frac{4 \pi^{2} }{GM} = r^{3} \\ 
T^{2} *\frac{GM}{4 \pi^{2} } = r^{3}$

Rearrange:
$r^{3} = T^{2} *\frac{GM}{4 \pi^{2} } \\ 
r^{3}= \frac{T^{2} *GM}{4 \pi^{2} } \\ 
r^{3}= \frac{GMT^{2}}{4 \pi^{2} } \\ 
r^{3} = GMT^{2}/4 \pi^{2}$

Since $x^{3}= \sqrt[3]{x}$ , then
$r^{3} = GMT^{2}/4 \pi^{2} \\ 
r= \sqrt[3]{GMT^{2}/4 \pi^{2}}$
