The two lines with arrows are parallel, which means angles A and B are supplementary.

So we have

A + B = 180º

(6x - 35)º + (3x + 53)º = 180º

(9x + 18)º = 180º

(9x)º = 162º

x = 18

This means angle A has measure

A = (6x - 35)º = 73º

A particle moves so that r(t) = ati + b sin atj. Show that the magnitude of the acceleration of the particle is proportional to

ValentinkaMS [17]

Answer:

Step-by-step explanation:

Given

Position of particle is $r(t)=at\hat{i}+b\sin (at)\hat{j}$

i.e. distance from x axis is $b\sin (at)---1$

Distance from y axis at

velocity is given by $v=\frac{\mathrm{d} r}{\mathrm{d} t}$

$v=a\hat{i}+ba\cos (at)\hat{j}$

Similarly acceleration is given by

$a=\frac{\mathrm{d} v}{\mathrm{d} t}$

$a=0\hat{i}-a^2b\sin (at)\hat{j}$

Magnitude of acceleration is $=\sqrt{(-a^2b\sin (at))^2}$

$=a^2b\sin (at)----2$

From 1 and 2 we can see that

Magnitude of acceleration is proportional to distance from x axis

$a\propto distance\ from\ x-axis$

A large aquarium contains only two kinds of fish, guppies and swordtails. If 3/4 of the number of guppies is equal to 2/3 of

Jlenok [28]

Answer:

$\frac{8}{17}$ of fish in this aquarium are guppies.

Step-by-step explanation:

Let x be the number of guppies and y be the number of swordtails in the aquarium,

According to the question,

$\frac{3}{4}\text{ of } x=\frac{2}{3}\text{ of }y$

$\frac{3x}{4}=\frac{2y}{3}$

By cross multiplication,

$9x=8y$

$\implies \frac{x}{y}=\frac{8}{9}$

Thus, the ratio of guppies and swordtail fishes is 8 : 9

Let guppies = 8x, swordtail = 9x

Where, x is any number,

Since, the aquarium contains only two kinds of fish, guppies and swordtails,

So, the total fishes = 8x + 9x = 17x

Hence, the fraction of fish in the aquarium are guppies = $\frac{\text{Guppies}}{\text{Total fishes}}$

$=\frac{8x}{17x}$

$=\frac{8}{17}$
