As you can see in the two terms, a multiplication by 4 has been distributed between a 12 and a 6.

This means that the original operation was

$4\cdot 12 + 4 \cdot 6 = 4(12+6) = 4\cdot 18 = 72$

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

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

Solve for x<br> -x + 4=22

bekas [8.4K]

Answer: x = −18

Step-by-step explanation:

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + -1x = 22 + -4

Combine like terms: 4 + -4 = 0

0 + -1x = 22 + -4

-1x = 22 + -4

Combine like terms: 22 + -4 = 18

-1x = 18

Divide each side by '-1'.

x = -18

Simplifying

x = -18

Helppppppppppppppp pleaseeeeee!

stepan [7]

Answer and Explanation:

You got the first one right!

2. You do the same as you did for the first one: to combine the exponents, you multiple 2 by 9 = 18, and now 18 is your new exponent.

$3^{2*9} = 3^{18}$ , which is the answer

3. Here, you can split up the inside so that you have:

$2^5*(y^2)^5= 32*y^{2*5}=32y^{10}$ , which is the answer

Hope this helps! Please give me brainliest if possible.
