. How do we write simple expressions using long & synthetic division? Explain

Mathematics

Answer:

For not exact divisions: Writing the results as Quotient + Remainder over the Divisor.

For exact division: just the quotient.

Step-by-step explanation:

Hi there,

In both algorithms, for long and synthetic divisions we must write the result as an expression following that order:

Dividend: Divisor=Qx+\frac{Rx}{Dx}

When the Division leaves no Remainder, i.e. an exact, the Remainder is equal to zero, so

Dividend: Divisor=Qx

Check below for the algorithms for each division and the way of writing their expressions (results).

Find the value of cos θ if the angle θ is in the third quadrant and sinθ= -0.8
Rudiy27

Correct option is D) -0.6.

<u>Step-by-step explanation:</u>

We have sin\alpha  = -0.8 . Also, we know that cos\alpha  = \sqrt{1- (sin\alpha } )^{2} . Let's find out value of cos\alpha  using above formula:

cos\alpha  = \sqrt{1- (sin\alpha } )^{2}

⇒ cos\alpha  = \sqrt{1- (sin\alpha } )^{2}

⇒ cos\alpha  = \sqrt{1- (-0.8 } )^{2}

⇒ cos\alpha  = \sqrt{1- (0.64 } )^{}

⇒ cos\alpha  = \sqrt{0.36}

⇒ cos\alpha  = 0.6

But we know that cos\alpha is negative in third quadrant , Therefore cos\alpha  = -0.6.

Hence, correct option is D) -0.6.

to solve the system of equations below, Becca isolated x^2 in the firs equation and then substituted it into the second equation
bija089 [108]

The resulting equation if Becca isolated x² in the first equation and then substituted it into the second equation is (9-y²) / 25 - y²/36 = 1

<h3>Equation</h3>

x² + y² = 9

x²/25 - y²/36 = 1

From (1)

x² = 9 - y²

substitute x² = 9 - y² into (2)

x²/25 - y²/36 = 1

(9-y²) / 25 - y²/36 = 1

Therefore, the resulting equation is option C; (9-y²) / 25 - y²/36 = 1
