Answer:

The value of x is 2\sqrt[3]{2}

Step-by-step explanation:

We are given 2+x^3=18

We need to solve for x

First we subtract 2 both sides

x^3=18-2=16

Taking cube roots both sides to isolate x

x=\sqrt[3]{16}

Simplify the radical

x=2\sqrt[3]{2}

Thus, The value of x is 2\sqrt[3]{2}

How many inches is each slice of pizza?
mariarad [96]

Hey!


First, let's find the area. The formula for finding area of a circle is: π · r²


Radius is ½ of the diameter. Divide the diameter by 2 to get the radius.


d = 18

18 ÷ 2 = 9


r = 9

r² = 9 × 9 = 81


The area of the whole pizza is 81π. There are 10 slices. Divide the area of the whole pizza by 10 to find the area of 1 slice.


81π ÷ 10 = 8.1π


<em>That means each slice is 8.1π inches²</em>

how do you solve this problem. there are approximately 2.1 million deaths per year in country A. Express this quantity as deaths
slamgirl [31]
Well... we know that... there are 365 days in a year, unless is a leap-year, but we'll use 365 anyway

and each day has 24hrs, each hr has 60 minutes

so. let us use those ratios

\bf 2.1million\iff 2.1E6\iff 2,100,000\qquad thus&#10;\\\\\\&#10;\cfrac{2100000\ deaths}{1\ year}\cdot \cfrac{1\ year}{365\ day}\cdot \cfrac{1\ day}{24\ hr}\cdot \cfrac{1\ hr}{60\ minute}

so.. multiply and simplify, cancelling out any like-units atop and bottom

notice, all we do, is use the ratios, in a way, that if we need one unit to be changed, we flip the ratio

for example, to toss away "year" unit, since in the first fraction is at the bottom, then we put it on the top on the ratio, year/year  = 1, effectively cancelling the unit

=》

-  {x}^{2}  - 8x - 15

=》

-  {x}^{2}  - 5x - 3x - 15

=》

- x(x + 5) - 3(x + 5)

=》

( - x - 3)(x + 5)

so, required zeroes are : -3 and -5
