Answer:

338\sqrt{x} -72\sqrt{2y}

Step-by-step explanation:

The expression is

2(4\sqrt{16x})-2(4\sqrt{2y}+34  \sqrt{81x}-4(4\sqrt{32y}  )

Where x\geq 0 and y\geq 0

First, we use distributive property

8\sqrt{16x}-8\sqrt{2y}+34\sqrt{81x}-16\sqrt{32y}

Then, we simplify square roots

8(4)\sqrt{x} -8\sqrt{2y}+34(9)\sqrt{x}  -16(4)\sqrt{2y}

Now, we multiply and group similar roots

32\sqrt{x} -8\sqrt{2y} +306\sqrt{x} -64\sqrt{2y} \\(32+306)\sqrt{x} +(-8-64\sqrt{2y} )\\338\sqrt{x} -72\sqrt{2y}

Therefore, the simpliest form of the given expression is

338\sqrt{x} -72\sqrt{2y}

the given expression is :

2(4√16x) - 2(4√2y) + 34√81x - 4(4√32y)

⇒ 8(√16x) - 8(√2y) + 34√81x - 16√32y  

⇒8×4√x - 8√2y + 34×9√x - 16√16×2y     [∵ √16 = 4 and √81 = 9]

⇒32√x - 8√2y + 306√x - 16×4√2y

⇒(32√x + 306√x) - 8√2y  - 16×4√2y      

⇒338√x -72√2y

Answer:

Using the distance formula, when I plugged in the information, the answer I got was the square root of 85. (B)

explanation:

C(x₁ , y₁) and T(x₂ , y₂) OR C(0,4) and T(-6,-3)

CT=√[(x₂ - x₁)² + (y₂ - y₁)²] =√[(-6-0)² + (-3 - 4)²]

CT=√[(36) + (49)} = CT = √85

The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.
marshall27 [118]

Please consider the graph.

We have been given that graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.  We are asked to choose the weights, which are within 2 standard deviations of the mean.

We can see from our graph that mean of the weights is 9.5 and standard deviation in 0.5.

The data point that would be below two standard deviation is: 9.5-2\times 0.5 that is 9.5-1=8.5.

The data point that would be above two standard deviation is: 9.5+2\times 0.5 that is 9.5+1=10.5.

Now we need to check the data points that lie within 8.5 and 10.5.

Upon looking at our given choices, we can see that 8.9, 9.5 and 10.4 pounds lie within 2 standard deviation of the mean.

Therefore, 8.9 lbs, 9.5 lbs and 10.4 lbs are correct choices.

A farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant prod
-Dominant- [34]

Answer:

Step-by-step explanation:

Given that a farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces

When we consider this graph as a straight line, the two points lying on the line would be

(30, 30) and (34, 28) taking n as horizontal and y vertical

Using two point equation we find that

the equation of the line is

\frac{y-y_1}{y_2-y_1} =\frac{x-x_1}{x_2-x_1}

Substitute the points as x =n

\frac{y-30}{28-30} =\frac{x-30}{34-30}\\y-30 = -0.5(x-30)\\y = -0.5x+45

is the linear relationship between n and y
