The answer is 7
hope this helps!
Step-by-step explanation:
x = mass of apples
y = mass of strawberries
z = mass of the box
x = 3y
x + z = 16240
y + z = 6350
let's subtract the second from the first equation
x + z = 16240
- y + z = 6350
-----------------------
x - y + 0 = 9890
using the first identity in that result gives us
3y - y = 9890
2y = 9890
y = 4,945 g
x = 3y = 3×4945 = 14,835 g = the mass of the apples
If we write y=f(x)=(x-h)²+k, then y-k=(x-h)². This is vertex form where the vertex is (h,k)=(3,3) so h and k are both 3. We can see this if we put x=3 in the shifted function. This is a minimum point for the function because for every other x f(x) is greater then 3. The minimum point is the vertex.
8, that is the same as saying what divided by 4 is 2, and 8 divided by 4 is 2. Thus, 2 is 1/4th of 8.
The area of a circle is equal to:
r = 1/2 the diameter
1/2 of 14 is 7
7 squared is 49
<em><u>The area is 49π</u></em>
