Hi!

<h3>We need to isolate b on one side. </h3>

<em>Multiply by 4 on both sides. </em>

-83 * 4 = b/4 * 4

<u>-332 = b</u>

<h2>The answer is b = -332</h2>

<em>To check your answer, put in the value of b. </em>

-83 = -332/4

-83 = -83

<u>This equation is correct. </u>

Hope this helps! :)

Im guessing you would like to get B by itself.

First you would divide both sides by 4. The four would cancel itself out with B and It would multiply -83 into -332

So your answer would be -332 = B

-83*4 = (B/4)4

-332 = B

Michael Chan leaves a dock in his motorboat and travels at an average speed of 9 mph toward the Isle of Shoals, a small island o
horsena [70]

Since the motor boat left the dock 2 hours before the tour boat, their meeting point will be 27 miles from the dock from which both boats departed after 3 hours.

<h3>What is the distance?</h3>

Distance is the movement of an object regardless of direction. The distance can be defined as the amount of length an object has covered, regardless of its starting or ending position

We know that r × t = d

r = rate of speed

t = time

d = distance

For the motor boat

9 × t = d = rate × time

For the tour boat

27 × (t - 2) = d = rate × time

When they both cover the same distance in the same amount of time, they will eventually cross paths.

They both cover the same d-mile distance, so:

9 ×t = 27 × (t - 2)

Simplify to get:

9 × t = 27 × t - 54

18 t = 54

t = 3

The motor boat will have traveled at 9 mph for 3 hours to make a distance of 9 × 3 = 27 miles.

The tour boat will have traveled at 27 mph for 1 hour to make a distance of 1 × 27 = 27 miles.

Since the motor boat left the dock 2 hours before the tour boat, their meeting point will be 27 miles from the dock from which both boats departed after 3 hours.

3cis(5pi/4) in polar form
madreJ [45]
Rectangular form:
z = -2.1213203-2.1213203i

Angle notation (phasor):
z = 3 ∠ -135°

Polar form:
z = 3 × (cos (-135°) + i sin (-135°))

Exponential form:
z = 3 × ei (-0.75) = 3 × ei (-3π/4)

Polar coordinates:
r = |z| = 3 ... magnitude (modulus, absolute value)
θ = arg z = -2.3561945 rad = -135° = -0.75π = -3π/4 rad ... angle (argument or phase)

Cartesian coordinates:
Cartesian form of imaginary number: z = -2.1213203-2.1213203i
Real part: x = Re z = -2.121
Imaginary part: y = Im z = -2.12132034

Help please me!!!!!!!!!!!

D:  We solve this in exactly the same way in which we solved the previous area problem.  Side length is s, area is s^2.  Here, side length is 5 in; area is 25 in^2.
the problem does say, however, not to include units in your answer.  Thus, just write "25."
