I need the solution and the work for it... for each of the multiple choices.
Vlad1618 [11]

For this case we have the following equation:

x ^ 3 = 375

We must find the value of "x":

We apply cube root on both sides of the equation to eliminate the exponent:

x = \sqrt [3] {375}

We can write 375 as 5 ^ 3 * 3

So:

x = \sqrt [3] {5 ^ 3 * 3}\\x = 5 \sqrt [3] {3}

Then, the correct options are:

x = \sqrt [3] {375}\\x = 5 \sqrt [3] {3}

Answer:

Option A and B

Solve the system of equations. y = -5x + 24 y = 4x - 21 a. ( -5, -1) c. ( -1, 5) b. ( 5, -1) d. No solution
Svetlanka [38]

y = -5x + 24

y = 4x - 21

Since both of these equations are equal to Y, theyre equal to each other.

So we can make an equation with y = -5x + 24 in one side and y = 4x - 21 on the other.

-5x + 24 = 4x - 21

Now in order to get the value of x we need to isolate it in one side of the equation. We can do this by subtracting 24 from both sides of the equation:

-5x + 24 - 24 = 4x - 21 - 24

-5x = 4x - 45

Now we subtract 4x from both sides so the 4x shift to the other side

-5x - 4x = 4x - 4x - 45

-9x = -45

Finally divide both sides by -9 so x is by itself

(-9)÷(-9x) = -(45)÷(-9)

x = 5

Since we did all of this to BOTH sides of the equation, both sides are still equal to each other and the equation still is true.

Now apply x = 5 to either of the initial equations to find the value of Y

y = -5x + 24 or y = 4x - 21

(I'll do both but u only need one)

y = -5(5) + 24

y = -25 + 24

y = -1

y = 4(5) - 21

y = 20 - 21

y = -1

Either way, X is 5 and Y is -1

Answer (5, -1)

How do you eliminate the parameter theta to find a Cartesian equation of the curve: x=sin(1/2 theta), y=cos(1/2 theta), 0 is les
kiruha [24]
The answer to the problem is as follows:

x = sin(t/2) 
<span>y = cos(t/2) </span>

<span>Square both equations and add to eliminate the parameter t: </span>

<span>x^2 + y^2 = sin^2(t/2) + cos^2(t/2) = 1 </span>

<span>The final step is translating the original parameter limits into limits on x and y. Over the -Pi to +Pi range of t, x varies from -1 to +1, whereas y varies from 0 to 1. Thus we have the semicircle in quadrants I and II: y >= 0.</span>
