Solve for d.<br> d^3 + 27 = 0<br> Write your answers in simplified, rationalized form.
tester [92]

Answer:

d=-3

Step-by-step explanation:

d3+27=0

Step 1: Subtract 27 from both sides.

d3+27−27=0−27

d3=−27

Step 2: Take cube root.

d=(−27)(

The penguins currently living on an island are of two types, Chinstrap penguins and Gentoo penguins. The range of the heights of
velikii [3]

Answer:

The answer is "Option A"

Step-by-step explanation:

Using the range difference to calculate the maximum and minimum value.

The range of the chinstrap penguins are:  

R(c) = Max(c) - Min(c) = 13.2

The range of the Gentoo penguins are:

 R(g) = Max(g) - Min(g) = 15.4

For point A:

Max(c) = x\\\\Max(g) = x + 5.8\\\\R(c) = x - Min(c) = 13.2 \to  x = 13.2 + Min(c)\\\\R(g) = x + 5.8 - Min(g) = 15.4 \to  x = 9.6 + Min(g)

equate both of them

13.2 + Min(c) = 9.6 + Min(g)Min(g) - Min(c) = 3.6

It indicates that Min(c) surpasses Min(g), whereas Max(g) exceeds Max (c).

Therefore, the Max is picked for g for all penguins and the minimum is picked for c.    

Range of all penguins = Max(g) - Min(c) = x + 5.8 - x + 13.2 = 19

Therefore, it will be determined as the option.

For point B:

In estimating the range the median height cannot help.

For point C:

In order to calculate the variety, the connection between both the mean height cannot be sued.

C. 9 square roots of 2

To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:

Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by \sqrt{2} will be 18. Knowing this, we can write out an equation:

u*\sqrt{2} = 18

u = \frac{18}{\sqrt{2} }

<u>Multiply both sides by </u>\sqrt{2}<u> in order to get rid of the root in the denominator:</u>

u = \frac{18*\sqrt{2}}{\sqrt{2} * \sqrt{2}}

u = \frac{18*\sqrt{2} }{2}

u = 9\sqrt{2}

If you'd like me to explain how I got to the answer any further, just ask!
