What is the solution to the equation -M+KX=J

marta [7]

Answer:

X = (J+M)/K

Step-by-step explanation:

Undo what has been done to the variable, in reverse order. The variable has been multiplied by K and M subtracted from the result. So, we first add M (to undo the subtraction), then we divide by K (to undo the multiplication).

KX = J +M . . . . . . M added to the given equation

X = (J + M)/K . . . . the result of that is then divided by K

___

Since these are all capital letters, we might assume they represent vectors and/or matrices. If so, the "divide by K" step needs to be "multiply on the left by K^-1, the matrix inverse of K."

Then your solution looks like

X = K⁻¹·(J + M)

Aidan makes 12 bracelets on Monday. He makes 8 more bracelets each day from Tuesday through Thursday. How many bracelets does Ai

BARSIC [14]

Answer:

On Friday he did not make any bracelets He makes 8 more bracelets each day from Tuesday through Thursday

Step-by-step explanation:

He made 12 bracelets on Monday

For 3 days (from Tuesday to Thursday) he added 8 more each day)

8*3=24

24+12 = 36

M =12

T= 20 (12+8)

W=28(20+8)

Th=36(28+8)

F=36 (still has 36 because on Friday he did not make 8 more bracelets)

8*3=24

24+12 = 36

Find the conjugate of the complex number 8+12i<br> 1) 96<br> 2) 8-12i<br> 3) -96i<br> 4) 20

timama [110]

Option 2 8-12i is correct.

Step-by-step explanation:

The conjugate of the complex number is obtained by changing the sign of the imaginary part.

In complex number 8+12i

8 is the real part and 12i is the imaginary part

The conjugate of 8+12i is 8-12i

So, Option 2 8-12i is correct.

Andrew is flying a kite at a height of 120ft. While the wind is carrying the kite horizontally away from her at the rate of 24ft

Paha777 [63]

Answer:

The string of the kite is being let out at the rate of 19.2 ft/sec.

Step-by-step explanation:

See the diagram attached.

The vertical height (BK) of the kite is 120 ft.

The kite string is of length (AK) of 200 ft.

Therefore, the horizontal distance (AB) from Andrew to kite is = $\sqrt{200^{2} - 120^{2}} = 160$ ft.

Now, applying the Pythagoras Theorem,

AB² + BK² = AK²

⇒ l² + h² = s² {Where, l is the horizontal length, h is the height and s is the string length}

Differentiating with respect to time t both sides

$2l\frac{dl}{dt} + 0 = 2s\frac{ds}{dt}$ {Since, height of kite is constant}

⇒ $2 \times 160 \times 24 = 2 \times 200 \times \frac{ds}{dt}$

⇒ $\frac{ds}{dt} = 19.2$ ft per sec.

Therefore, when the wind is carrying the kite horizontally at the rate of 24 ft/sec, then the string of the kite is being let out at the rate of 19.2 ft/sec. (Answer)
