Answer: A
Step-by-step explanation:
Each y value is half of the x value.
the equation for a parabola with focus (h, k+p) and directrix y=k-p is
so using your directrix y=-3, and knowing directrix is y=k-p, you have
-3=k-p.
similarly, knowing the focus is defined by (h,k+p) and your focus is (-5,-1)
you have the equation -1=k+p.
you now have a system of equations
which you can solve using any method, I will use elimination.
adding down
you now have k and can find p using either equation.
.
now you plug those in, getting the answer
Answer:
h = 8.00 inches , which is answer B
Step-by-step explanation:
The formula to calculate the Volume V of a cone is:
V = 1/3*pi*r²*h
Given:
V = 33.5 in³ pi = 3.14 and r = 2 in
This time the Volume is given, but you need to calculate the height h. So let's rewrite the formula, so it starts with h =
V = 1/3*pi*r²*h
multiply left and right of the = sign by 3
3/3*pi*r²*h = 3*V
divide left and right of the = sign by pi*r²
h = 3*V/(pi*r²)
V = 33.5 in³
pi = 3.14
r = 2 so r² = 4 in²
h = 3*33.5/(3.14*4)
h = 8.00 inches , which is answer B
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
