Answer:

D. last option

Step-by-step explanation:

distribute the exponents outside of parentheses to terms in side to get

x^10 y^20 z^5 on top

and x^2 y^2

then you can subtract the exponents of like terms from numerator and denominator to get

x^8 y^18 z^5

In the kite , AK=9 , JK=15 , and AM=16 .

Veronika [31]

Answer:

The Length of JM is 20.

Step-by-step explanation:

Given,

JKLM is a kite in which JL and KM are the diagonals that intersect at point A.

Length of AK = 9

Length of JK = 15

Length of AM = 16

Solution,

Since JKLM is a kite. And JL and KM are the diagonals.

And we know that the diagonals of a kite perpendicularly bisects each other.

So, JL ⊥ KM.

Therefore ΔJAK is aright angled triangle.

Now according to Pythagoras Theorem which states that;

"The square of the hypotenuse is equal to the sum of the square of base and square of perpendicular".

$JK^2=KA^2+AJ^2$

On putting the values, we get;

$(15)^2=9^2+AJ^2\\\\225=81+AJ^2\\\\AJ^2=225-81=144$

On taking square root onboth side, we get;

$\sqrt{AJ^2} =\sqrt{144}\\\\AJ=12$

Again By Pythagoras Theorem,

$AJ^2+AM^2=JM^2$

On putting the values, we get;

$JM^2=(12)^2+(16)^2\\\\JM^2=144+256=400$

On taking square root onboth side, we get;

$\sqrt {JM^2}=\sqrt{400}\\\\JM=20$

Hence The Length of JM is 20.

HELP PLZ!!!!- In 2012, on average, about 9.46 × 10^-1 pound of potatoes was produced for every 2.3 × 10^-5 power acre harvested.

sashaice [31]

Answer: The answer is 41.13 pounds (approx.).

Step-by-step explanation: Given that the average production of potatoes in 2012 was 0.946 pounds for every 0.000023 power acre harvested. We need to calculate the pounds of potatoes produced on average for each acre harvested.

For that, we need to divide the pounds of potatoes by number of acres harvested.

In 0.000023 acre harvested, ponds of potatoes = 0.946 ponds.

Therefore, in 1 acre harvested, pounds of potatoes is given by

$p=\dfrac{0.946}{0.000023}=41.13~\textup{(approx.)}$

Thus, the answer is 41.13 pounds (approx.).
