4] Which perfect square root is close to $\sqrt{39}$ ?

Well we know that 7 times 7 is 49, and 6 times 6 is 36, so our answer will be between $\sqrt{36}$ and $\sqrt{49}$

The closer root is $\sqrt{36}$ , so we can approximate that the square root of 39 is around 6.2.

5] We can do a similar step-by-step here.

4 times 4 is 16, and 5 times 5 is 20.

This gives us $\sqrt{16}$ and $\sqrt{20}$

Well, they are both equal distance from $\sqrt{18}$ (2), so we can do this:

We know it'll be between 4 and 5 (the number plot in the answer lets us know that too)

4 times 4 is 16

4.1 times 4.1 is around 16.8

4.2 times 4.2 is about 17.64

4.3 times 4.3 is 18.49

Now that we have an 18, we can stop going and see which one is closer.

18 - 18.49 = -0.49

18 - 17.64 = 0.36

4.2 times 4.2 is closer, so we can approzimate that $\sqrt{18}$ is around 4.2

Note] Hope this helps! Upon using a calculator I can confirm these answers are correct :D

Please match each function formula with the corresponding transformation of the parent function y= -x^2-1

pishuonlain [190]

Answer:

The answer in the attached figure

Step-by-step explanation:

we have the parent function

$y=-x^{2}-1$

case 1) Reflected across the x-axis

we know that

The rule of the transformation is

(x,y)------> (x,-y)

so

$y=-(-x^{2}-1)$

$y=x^{2}+1$

case 2) Reflected across the y-axis

we know that

The rule of the transformation is

(x,y)------> (-x,y)

so

$y=-(-x)^{2}-1$

$y=-x^{2}-1$

case 3) Translated left by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x-1,y)

so

$y=-(x+1)^{2}-1$

case 4) Translated right by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x+1,y)

so

$y=-(x-1)^{2}-1$

case 5) Translated down by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x,y-1)

so

$y=-(x)^{2}-1-1$

$y=-(x)^{2}-2$

case 6) Translated up by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x,y+1)

so

$y=-(x)^{2}-1+1$

$y=-(x)^{2}$

You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has

pickupchik [31]

Answer:

If you draw this out, you can see that total fence equation will be:

2L + 4W = 1200

Simplify, divide by 2

L + 2W = 600

L = (600-2W)

:

Area;

A = L*W

Substitute (600-2W) for L:

A = (600-2W)*W

A = -2W^2 + 600W; a quadratic equation

:

The dimension that will produce the greatest area will be the "axis of symmetry

which is: x = %28-b%29%2F%282a%29

:

In this equation a=-2, b=600

W = %28-600%29%2F%282%2A-2%29

W = %28-600%29%2F%28-4%29

W = +150 ft is the width

:

Find the length

L = 600 - 2(150)

L = 300 ft is the length

:

We can say the a field 300 by 150 gives he greatest area

:

This illustrated on a graph where y axis is the area and x axis is the width:
