Convert the measurements as indicated 4^1/4 ft to inches

Nadya [2.5K]

Answer:

Step-by-step explanation:

if it is (4)^(1/4) ft.

$4^{\frac{1}{4} } =(2^2)^{\frac{1}{4} }\\=2^{\frac{2}{4} }\\=\sqrt{2} ft\\=12\sqrt{2} ~inches.\\\approx 16.97 inches$

if it is (4^1)/4

then

$\frac{4^1}{4} =\frac{4}{4} =1 ~ft=12~inches$

What is the sum of n natural numbers: 1+2+...+n?

r-ruslan [8.4K]

$S=1+2+\cdots+(n-1)+n$

then we also have

$S=n+(n-1)+\cdots+2+1$

Pairing up the terms, we can find that

$2S=(1+n)+(2+n-1)+\cdots+(n-1+2)+(n+1)$

$2S=(n+1)+(n+1)+\cdots+(n+1)+(n+1)$

$S$ consists of $n$ terms, so there are $n$ copies of $n+1$ in the sum $2S$ . Then we find an immediate closed form for the sum:

$2S=n(n+1)\implies S=\dfrac{n(n+1)}2$

How do i graph the parabolas y = 1/32x^2

Pachacha [2.7K]

$y=\frac{1}{32}x^2 \\ \\x=-16 \Rightarrow y=\frac{1}{32} *(-16)^2=\frac{1}{\not32^1}*\not256^8=8\\ \\x=-8 \Rightarrow y=\frac{1}{32} *(-8)^2=\frac{1}{\not32^1}*\not64^2=2\\ \\x=0 \Rightarrow y=\frac{1}{32} *(0)^2=\frac{1}{\not32^1}*0=0 \\ \\x=8 \Rightarrow y=\frac{1}{32} *(8)^2=\frac{1}{\not32^1}*\not64^2=2 \\ \\x= 16 \Rightarrow y=\frac{1}{32} *( 16)^2=\frac{1}{\not32^1}*\not256^8=8$
