Turkey weigh 7kg how long to cook

Answers

If a turkey weighs 7kg or 14lbs, it must have a roasting time of 2 3/4 to 3 hours and a resting time of up to 60 minutes. This weight is good for 8 to 10 servings.

Roasting time is the time it is cooked inside the oven. Resting time is the time the turkey is taken out of the oven but left alone so that the heat inside the turkey will still continue to cook the meat within.

Roasting time varies on the weight of the turkey but the resting time has a maximum of 60 minutes.

3kg - 1 3/4 - 2 hrs.
4kg - 2 - 2 1/4 hrs
5kg - 2 1/4 - 2 1/2 hrs
6kg - 2 1/2 - 2 3/4 hrs
9kg - 3 1/2 - 4 hrs
11kg - 4 1/2 hrs

Use the discriminant to describe the roots of each equation. Then select the best description. x2 - 6x + 9 = 0

Answers

x² - 6x + 9 = 0

a = 1, b = -6, c = 9

Discriminant = b² - 4ac = (-6)² - 4*1*9 = 36 - 36 = 0

Since the Disciminant, D = 0, the roots are real and equal

The equation of a circle is (x - 3)2 + (y + 2)2 = 25. The point (8, -2) is on the circle.What is the equation of the line that is tangent to the circle at (8, -2)?

Answers

Answer:

The equation of the line that is tangent to the circle at (8, -2) is:

$x=8$

Step-by-step explanation:

We know that the line which is tangent at a point on a circle is perpendicular to the line joining the center of the circle and that point.

Here we are given the equation of a circle as:

$(x-3)^2+(y+2)^2=25$

The center of the circle is at: (3,-2)

( Since, the standard form of a circle with center at (h,k) and radius r is given by:

$(x-h)^2+(y-k)^2=r^2$ )

Also, the equation of a line joining (3.-2) and (8,-2) is given by:

$y-(-2)=(-2-(-2))/(8-3)* (x-3)\n\ni.e.\n\ny+2=(-2+2)/(5)* (x-3)\n\ni.e.\n\ny+2=(0)/(5)* (x-3)\n\ni.e.\ y+2=0\n\ni.e.\ y=-2$

Also, we know that the slope of this line is zero.

Also, we know that if two lines are perpendicular with slope m and m' respectively then,

$m\cdot m'=-1\n\ni.e.\n\nm'=(-1)/(m)$

Hence, we get that the slope of the tangent line is:

$(-1)/(0)$

Also, we know that:

The equation of a line with given slope m' and a passing through point (a,b) is given by:

$y-b=m'(x-a)$

Here (a,b)=(8,-2)

and $m'=(-1)/(0)$

i.e. the equation of the tangent line is:

$y-(-2)=(-1)/(0)(x-8)\n\ni.e.\n\ny+2* 0=-1(x-8)\n\ni.e.\n\n-1* (x-8)=0\n\ni.e.\n\n(x-8)=0\n\ni.e.\n\nx=8$

Hello,
