Answer:

314 m²

Step-by-step explanation:

the formula for the surface area of a sphere (As) is

As = 4×pi×r²

the radius r (half of the diameter) is clearly indicated as 5m.

so, As = 4×3.14×5² = 4×3.14×25

I don't even need a calculator for this, as 4×25 = 100

so, As = 100×3.14 = 314

(you know, when multiplying by 10, the decimal point moves right one position. multiply by 100 it moves 2 positions, and so on).

What’s in a equation or Leniar function y axis 1 and negative 7 and x axis negative 3 and 1
Elodia [21]

A linear function is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. For example, a common equation,  

y

=

m

x

+

b

, (namely the slope-intercept form, which we will learn more about later) is a linear function because it meets both criteria with  

x

and  

y

as variables and  

m

and  

b

as constants.  It is linear: the exponent of the  

x

term is a one (first power), and it follows the definition of a function: for each input (

x

) there is exactly one output (

y

).  Also, its graph is a straight line.

PLEASE HELP!!<br> Factor <br> 6x^2-42x-54<br><br> Please show work!
skad [1K]

first, rewrite 54 as 6•9

next, rewrite 42 as 6•7

then, that gets you 6x^2 -6•7x- 6•9

lastly, factor out the common term (6)

and then you get 6(x^2-7x-9)
