Write in index form 12 × 12 × 12 × 12 × 12 × 12 × 12 × 12

iris [78.8K]

Answer:

$\sf{12^{8} }$

Step-by-step explanation:

12 × 12 × 12 × 12 × 12 × 12 × 12 × 12 = $\sf{12^{8} }$

$\sf{12^{8} }$ = 429,981,696

An easy way to think of this is that there are 12 is being multiplied by itselg 8 times (there are 8 12s). Similar to how squared numbers work...

Hope this helps! If you need further explanation, let me know!

F f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (f circle g) (x)?

seraphim [82]

f°g mean apply g(x) and then use result of g(x) as "x" in f(x)

so as g(x) = x² +1 and f(x) = 3x+2

so if we call g(x) X we have

f( X) = 3 X +2

now we replace " X" for it's value

f(X) = 3 ( x² +1) +2

f(X) = 3x² +3 +2

f(X) = 3x² +5

so f°g = 3x² +5

Semenov [28]

the volume of the sculpture is $Volume = 64.11ft^3$ .

Step-by-step explanation:

Here we have , An artist creates a cone-shaped sculpture for an art exhibit. If the sculpture is 5 feet long and has a base with a circumference of 21.980 feet, We need to find the volume of the sculpture . Let's find out:

We know that

⇒ $Circumference = 2\pi r$

According to question ,

⇒ $21.980 = 2\pi r$

⇒ $\frac{21.980}{2\pi} = r$

⇒ $r=3.5$

Now , We know that Volume of cone :

⇒ $Volume = \frac{1}{3}\pi r^2h$

⇒ $Volume = \frac{1}{3}(3.14) (3.5)^25$

⇒ $Volume = 64.11ft^3$

Therefore , the volume of the sculpture is $Volume = 64.11ft^3$ .
