Find the slope of the line perpendicular to 2x + y = 3.

Mathematics
1 answer:
Temka [501]3 years ago

Answer:

The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is −2 - 2 . The equation of a perpendicular line to y=−2x+3 y = - 2 x + 3 must have a slope that is the negative reciprocal of the original slope.

For each of 2 ≤ n ≤ 5, compute c(n, 0) + c(n, 2) + ⋅⋅⋅ + c(n, 2k), where 2k is largest even integer ≤ n, and compute c(n, 1) + c
Ksivusya [100]
Denote C(n,m)=\dbinom nm. Then

n=2\implies\displaystyle\binom20+\binom22=1+1=2
n=3\implies\displaystyle\binom30+\binom32=1+3=4
n=4\implies\displaystyle\binom40+\binom42+\binom44=1+6+1=8
n=5\implies\displaystyle\binom50+\binom52+\binom54=1+10+5=16

In general, it would appear that

\displaystyle\sum_{k=0}^{2\lfloor\frac n2\rfloor}\binom n{2k}=2^{n-1}

On the other hand,

n=2\implies\displaystyle\binom21=2
n=3\implies\displaystyle\binom31+\binom33=3+1=4
n=4\implies\displaystyle\binom41+\binom43=4+4=8
n=5\implies\displaystyle\binom51+\binom53+\binom55=5+10+1=16

so that in general, we also get

\displaystyle\sum_{k=0}^{2\lfloor\frac{n-1}2\rfloor+1}\binom n{2k+1}=2^{n-1}

Which equation finds m given E, and C
Anastasy [175]

Answer:

C

Step-by-step explanation:

E=mc^2

To find m, isolate m from the rest of the variables, E and C. Since m and c^2 are being multiplied, use the inverse of multiplication, division, to undo the multiplication.

E/c^2 = m.

There you go! Have a nice day!

What is the base 8 representation of 30
n200080 [17]
When converting from base 10 to another base, we first divide by that base
30 / 8 = 3 remainder of 6 (which becomes the rightmost base 8 digit).

we then get the 3 which is smaller than the base and so 3 becomes the final leftmost digit.

(base 10) 30 = (base 8) 36
