Answer:
axis of symmerty = x coordinate of vertex = -b/2a
-6/2 = <u>-3 = x</u>
<u />
vertex = (-3,y)
-3^2 +6(-3)
9-18 = -9 = y
<u>(-3,-9) = vertex</u>
Step-by-step explanation:
The number of days is 10 if, in a poultry farm, 50 hens give 200 eggs in 2 days.
<h3>What is a fraction?</h3>
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
On a poultry farm, 50 hens give 200 eggs in 2 days.
It is required to find the number of days will 20 hens require to give 400 eggs:
Let x be the number of days:
(50×2)/200 = (20x)/400
x = 10
Thus, the number of days is 10 if, in a poultry farm, 50 hens give 200 eggs in 2 days.

Answer:
D
Step-by-step explanation:
(-1) + (-1) = -2... so 500 times... it would be -500.
3/10 is the same as 15 out of 50. subtract 15 from 50 and you get 35, the answer.
ANSWER
EXPLANATION
The given function is
We take natural log of both sides;
Recall and use the product rule of logarithms.
This implies that:
We now differentiate implicitly to obtain;
Multiply through by y,
Substitute y=x²cosx to obtain;
Expand:
