Is dis a question...??????

Adam buys a bigger turkey than he needs the turkey he buys weighs 7kg the cooking instructions are:less than 4kg-allow 20 minutes per kg, plus 70 minutes

over 4kg allow 20 minutes per kg, plus 90 minutes

always leave the turkey to rest for 30 minutes before carving to retain moisture.

he plans to carve the turkey at 17:15.

what time should he start cooking the turkey?

Answers

Given:
7 kg turkey

cooking instructions:
over 4kg allow 20 minutes per kg, plus 90 minutes
always leave the turkey to rest for 30 minutes before carving.

7kg * 20 minutes/kg = 140 minutes

140 minutes + 90 minutes = 230 minutes
230 minutes + 30 minutes rest = 260 minutes

260 minutes * 1hr/60 minutes = 4 hours 20 minutes

17:15 is 5:15 pm

17:15 - 4:20 = 12:55 pm

Adam should start cooking at 12:55 pm

Find x and y of this triangle.

Answers

Question

Find x and y of this triangle.

Answer:

x = 52°

y = 23°

Step-by-step explanation:

the sum of the interior angles of a triangle is 180°

from the picture you have 90°, 67° and y in one triangle

and 90°, 38° and x in the other.

triangle with y:

180 - 90 - 67 = 23°

triangle with x

180 - 90 - 38 = 52°

Please help!!Solve the equation and express each solution in a+bi form.
x^4-7x^2-8=0
a. x = -1, 1, 2 sqrt 2, or -2 sqrt 2
b. x = -i, i, 2 sqrt 2, or -2 sqrt 2
c. x = -1, 1, 2 sqrt 2i, or -2 sqrt 2i
d. x = -i, i, 2 sqrt 2i, or -2 sqrt 2i

Answers

Because this is a fourth degree that will be tricky to factor as it is, we will do a u substitution. Let $x^2=u$ . We can now rewrite that polynomial in terms of u: $u^2-7u-8=0$ . Filling into the quadratic formula we have $u=(7+/-√(49-4(1)(-8)))/(2)$ . Simplifying down $u=(7+/-√(81))/(2)$ and $u=(7+9)/(2)$ or $u=(7-9)/(2)$ . That means that u = 8 or u = -1. But don't forget that we let $u=x^2$ , so we have to put x-squared back in for u. That gives us $x^2=8$ which simplifies down to $+/-2√(2)$ . That also gives us $x^2=-1$ . When we take the square root of -1, we have to use the fact that -1 = i^2, so we sub that in to get $x=+/-i$ . All in all, your solutions are as follows: $2√(2),-2√(2),i,-i$ which is choice b.
