Answer:

$\frac{bd}{(a + c)} = \frac{3 \times ( - 4)}{ (- 2) + ( - 12)} = \frac{( - 12)}{( - 14)} = \frac{6}{7} \\$

<h3>6/7 is the right answer.</h3>

What is the constant term of the quotient when 2x^3-3x^2 + 4x-2 is divided by x^2-x+2?

AlladinOne [14]

Answer:

-1

Step-by-step explanation:

See the attachment for the polynomial long division. The constant in the quotient is -1.

_____

Here, there is a remainder of -x. If there were no remainder the constant in the quotient is the ratio of the constant in the dividend to the constant in the divisor: -2/2 = -1.

That could be a first guess in a "guess and check" solution approach.

<em>Guess</em>: first term of binomial quotient is (2x^3)/x^2 = 2x; last term of binomial quotient is -2/2 = -1. So, the quotient is guessed to be (2x -1).

<em>Check</em>: (2x -1)(x^2 -x +2) = 2x^3 -3x^2 +5x -2

Subtracting this from the actual dividend gives a remainder of -x. This has a lower degree than the divisor, so no further adjustment of the quotient is required.

Kayla’s dollhouse has 15.15 square feet downstairs and 6.45 square feet upstairs. What is the estimated total area if you round

Hitman42 [59]

The area of Kayla's dollhouse upstairs = 15.15 square feet

The area of Kayla's dollhouse downstairs = 6.45 square feet

To find the estimated Total area of Kayla's dollhouse, we would apply the Addition Operation

The estimated total area is calculated using the formula :

Area of the dollhouse upstairs + Area of the dollhouse downstairs

Rounding to the decimals to the nearest tenth

The area of Kayla's dollhouse upstairs to the nearest tenth = 15.2 square feet

The area of Kayla's dollhouse downstairs to the nearest tenth = 6.5 square feet

15.2 square feet + 6.5 square feet = 21.7 square feet

The estimated total area of Kayla's dollhouse is 21.7 square feet

Pregnant women metabolize some drugs at a slower rate than the rest of the population. The half-life of caffeine is about 4 hour

UkoKoshka [18]

Answer:

Husband:

The husband will have 16.35 mg of caffeine in his body at 7 pm.

Woman:

The pregnant woman will have 51.33 mg of caffeine in her body at 7 pm.

Step-by-step explanation:

The amount of caffeine in the body can be modeled by the following equation:

$C(t) = C(0)e^{rt}$

In which C(t) is the amount of caffeine t hours after 8 am, C(0) is how much coffee they took and r is the rate the the amount of caffeine decreases in their bodies.

110 mg of caffeine at 8 am,

So $C(0) = 110$
