An extremely handsome math teacher was on a farm and he counted 32 animals; all pigs and chickens. Then he counted the number of

feet. The total was 88. Find the number of pigs and the number of chickens. (Hint: You need to take the number of legs each animal has into consideration.)

Answer:

12 pigs and 20 chickens

Step-by-step explanation:

Chicken = 2 legs

Pig = 4 legs

(15 * 4) + (17 * 2) = 88                          NO

(12 * 4) + (20 * 2) = 88                         Yes, and 12 + 20 = 32

Write the equation of this circle in standard form. A) (x - 2)2 + (y - 3)2 = 4
Vika [28.1K]

Answer:

x^2 + y^2 -4x -6y + 9 = 0

Step-by-step explanation:

To write a circle in standard form, expand the equation of the circle and move all terms to one side.

(x-2)^2 + (y-3)^2 = 4\\x^2 -4x + 4 + y^2 -6y + 9 = 4\\x^2 +y^2 - 4x - 6y + 13 = 4\\x^2 + y^2 -4x -6y + 9 = 0

P(x)⋅Q(x)=R(x); if P(x)=x+2 and R(x)=x3−2x2−6x+4, what is Q(x)?
STatiana [176]

Answer:  Q(x) = x² - 4x + 2

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

P(x) · Q(x) = R(x)   ⇒   Q(x) = R(x)/P(x)

R(x) = x³ - 2x² - 6x + 4     ÷     P(x) = x + 2

I will use synthetic division (but you can also use long division).

-2 |  1     -2     -6     4  

    <u>|  ↓    -2       8    -4   </u>

       1    -4       2      0   ← remainder

       

The reduced polynomial is: x² - 4x + 2

Can someone please help with my math real quick?
Jobisdone [24]

Answer:

5.0003 x 10^-5

I believe this is the answer!

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. Hope this helps!
