Auditoriums are often designed so that are fewer seats per row for rows closer to the stage. Suppose you are sitting in row 18 i

zhannawk [14.2K]

Answer:

(a) $22$ (b) $109$

Step-by-step explanation:

GIVEN: Auditoriums are often designed so that are fewer seats per row for rows closer to the stage. Suppose you are sitting in row $18$ in an auditorium and notice that there are $73$ seats in your row. It appears the row in front of you has $70$ seats and the row behind you has $76$ seats. Suppose this pattern continues throughout the auditorium.

TO FIND: a) How many seats are in the first row b) How many seats are in the $30th$ row?

SOLUTION:

total seats in $row_{19}=76$

total seats in $row_{18}$ $=73$

total seats in $row_{17}=70$

as it clearly form an A.P. with $d=76-73=3$

(a)

let total seat in first row be $a$

as total seats in $row_{18}=73$

$row_{18}=a+(n-1)d$

$73=a+17\times3$

$a=22$

total seats in first row are $22$

(b)

total seats in $30th$ be $x$

$x=row_{1}+(30-1)3$

$x=22+29\times3$

$x=109$

total seats in $30th$ row are $109$

Find a unit vector that has the same direction as the given vector. 8i ? j + 4k

e-lub [12.9K]

Answer with Step-by-step explanation:

a.Let given vector

a=8i-j+4k

$\mid a\mid=\sqrt{(8)^2+(-1)^2+(4)^2}=9$

By using the formula

Magnitude of a vector= $\sqrt{x^2+y^2+z^2}$

Where x=Coefficient of i

y=Coefficient of j

z=Coefficient of k

Unit vector= $\hat{a}=\frac{a}{\mid a\mid}$

By using the formula

The unit vector= $\hat{a}=\frac{8i-j+4k}{9}=\frac{8}{9}i-\frac{1}{9}j+\frac{4}{9}k$

b.Let vector b=-2i+4j+2k

$\mid b\mid=\sqrt{(-2)^2+4^2+2^2}=2\sqrt 6$

$\hat{b}=\frac{-2i+4j+2k}{2\sqrt 6}$

Length of vector=6

Therefore, the vector in the direction of <-2,4,2> with length 6 is given by = $6\hat{b}=6\times \frac{-2i+4j+2k}{2\sqrt 6}$

The vector in the direction of <-2,4,2> with length 6 is given by = $-\sqrt 6(-i+2j+k)$

c. $\theta=\frac{\pi}{3}$

$\mid v\mid=8$

Let v= $v_x i+v_y j$

$v_x=\mid v\mid cos\theta$

$v_x=8cos\frac{\pi}{3}=8\times \frac{1}{2}=4$

$cos\frac{\pi}{3}=\frac{1}{2}$

$v_y=\mid v\mid sin\theta$

$v_y=8\times sin\frac{\pi}{3}=8\times \frac{\sqrt 3}{2}=4\sqrt 3$

$sin\frac{\pi}{3}=\frac{\sqrt 3}{2}$

Therefore, the vector v in component form= $4i+4\sqrt 3j$

what is the slope of the line 5x - 2y = -10? a. negative five halves b. five halves c. two fifths d. negative two fifths e. none

gtnhenbr [62]

5x-2y=-10
Making y the subject of the formula;
5x+10=2y
2y=5x+10
y= $\frac{5}{2} x+5$
The slope is 2.5 or five halves
