How many 5 digit license plate can be made using only the digits 2,3,4,5,6,7,8,9 if an odd digit must go first and second and re

Aliun [14]

Answer:

1,440

Step-by-step explanation:

if first two digits must be odd, then there are 4x3 or 12 combinations for that

if the next three digits can be even or odd but not repeats then there can be 6 (two odds remaining plus four evens) x 5 x 4 = 120

120 x 12 = 1,440

I need this answer asap

padilas [110]

Answer:

$a=64,b=0$

Step-by-step explanation:

Given;

$z=-1-\sqrt{3}i$

$r=\sqrt{(-1)^2+(-\sqrt{3})^2} =2$

$\phi =\tan^{-1}(\frac{-\sqrt{3} }{-1})=\frac{\pi}{3}$

$\arg(z)=2\pi-\frac{\pi}{3} =\frac{5\pi}{3}$

Apply DeMoivre's Theorem;

$z^n=r^n(\cos(n \theta) + i\sin(n \theta))$

$\Rightarrow z^6=2^6(\cos(6\times \frac{5\pi}{3}) + i\sin(6\times \frac{5\pi}{3}))$

$\Rightarrow z^6=64(\cos(10\pi) + i\sin(10\pi))$

$\Rightarrow z^6=64(1+ 0i)$

$\Rightarrow z^6=64+ 0i$

$\therefore a=64,b=0$

How much would you go up or down if the road stayed at 8% for one mile?

Ghella [55]

An 8% slope up is 422.4 feet up in one mile.

An 8% slope down is 422.4 feet down in one mile.

1 mile = 5,280 feet

8% of 1mile = 0.08 x 5,280-ft = 422.4-ft

Suppose a person wants to travel d miles at a constant speed of left parenthesis 60 plus x right parenthesis(60+x) mi/hr, where

Tpy6a [65]

A) We can use the linear approximation to estimate the amount of time it takes. We're given that the linear approximation to t at the point x = 0 is t(x) ≈ L(x) = d(1–(x/60)). If it drives 84 miles at 62 mi/hr, we'll plug 84 in for d and 62 – 60 = 2 in for x to approximate the amount of time it takes.

L(2) = 84(1 – 2/60) = 81.2 minutes

So the answer for part a is 81.2 minutes.

b) Exact time = Distance/Speed = 84/62 = 1.35 hours, which is equivalent to 1.35 * 60 = 81.3 minutes.
