Answer:
2.8 miles.
True.
Step-by-step explanation:
Surface area = 4π r^2 (where r = the radius of the sphere)
24.63 = 4 π r^2
r^2 = 24.63 / 4π
r = √ ( 24.63 / 4π )
= 1.4 miles.
So the diameter = 2*1.4 = 2.8 miles (answer).
The answer to the second part of the question is true.
G ( x ) = 4 x + 1 ( spots → stars )
h ( x ) = x² - 2 ( stars → asteroids )
Composite function:
h ( g ( x ) ) = ( 4 x + 1 )² - 2 =
= 16 x² + 8 x + 1 - 2 =
= 16 x² + 8 x - 1 ( spots → asteroids )
Answer:
where's the question. you gave no information....
Step-by-step explanation:
I don't know what I have to work with...
Let's call the number "n"
if we write in an equation what you said it's like this:
n*2+4-n-3=n+1.
first i will move all the "n"s to the left and all the numbers to the right
n*2-n-n=1+3-4
which is....
0=0
this means that for EVERY number, if you double it, add four, subtract three, you will get this number plus one. <span />
X - 6 is th algebraic expession for six lss than a number. x represents the number and you are taking 6 away from it. This is the basis of all algebra
