Ann [662]

<u>Corrected Question</u>

In the year 2009, the cost of a flat screen television can be modeled by the equation C = -10t^2 + 500 where t is the number of years since 2009. Factor this cost polynomial.

Answer:

$C=10(50-t^2)$

Using express exponents, you write C=10(50-t^2)

Step-by-step explanation:

To factor the cost polynomial, $C=-10t^2+500$ , we follow these steps.

Step 1: Determine the greatest common divisor of the terms in the polynomial

The terms in the polynomial are $-10t^2$ and 500$

The greatest common divisor of $-10t^2$ and 500$ is 10.

Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.

$C=10\left(\dfrac{-10t^2}{10} +\dfrac{500}{10}\right)\\C=10(-t^2+50)\\$We can rewrite this as \\C=10(50-t^2)$

1. Name the formula for the Law of Sines? Can it be written any other way? What do the letters stand for? When you are solving t

EastWind [94]

Answer:

see explanation

Step-by-step explanation:

The formula for the Sine rule is

$\frac{a}{sinA}$ = $\frac{b}{sinB}$ = $\frac{c}{sinC}$

Where a, b and c are the sides of a triangle and A, B , C are the angles opposite the corresponding sides, that is

A is opposite side a, B is opposite side b, C is opposite side c

The sine rule is usually applied using a pair of the ratios, where

2 sides and an angle are known to find an unknown angle.

1 side and 2 angles are known to find an unknown side.

----------------------------------------------------------------------------------

There are 2 forms of the Cosine rule

(a) a² = b² + c² - (2bc cosA ) ← to calculate an unknown side

(b) cosA = $\frac{b^2+c^2-a^2}{2bc}$ ← to calculate an unknown angle

(a) is used given 2 sides of a triangle b and c are known with A being the included angle ( the angle between the 2 sides )

(b) is used when the 3 sides a, b and c are known

----------------------------------------------------------------------------------

If the angle A = 90° then cos90° = 0 and formula (a) becomes

a² = b² + c² ← that is Pythagoras' identity

For adults, the RDA of the amino acid lysine is 12 mg per kg of body weight. How many grams per day should a 71.0kg adult receiv

Andreas93 [3]

Answer: There is 0.852 grams per day , 71.0 kg adult should receive.

Step-by-step explanation:

since we have given that

1 kg of body weight , the RDA of amino acid lysine = 12 kg per mg

So, we will use "Unitary Method":

For 71.0 kg of body weight , the RDA of amino acid lysine is given by

$12\times 71=852\ mg\\\\\text{ As we know that }1\ g=1000\ mg\\\\852\ mg=\frac{852}{1000}\ g=0.852\ g$

Hence, there is 0.852 grams per day , 71.0 kg adult should receive.
