Answer:
Step-by-step explanation:
you can eliminate the radical by squaring both sides of the equation
Answer:
30 because 3 x 5=15 then x2 it's 30
1.
the x value of the vertex in form
ax^2+bx+c=y
is
-b/2a
so
-2x^2+8x-18
x value of vertex is
-8/(2*-2)=-8/-4=2
plug it in to get y value
-2(2)^2+8(2)-18
-2(4)+16-18
-8-2
-10
vertex is at (2,-10)
or you could complete the square to get into y=a(x-h)^2+k, where the vertex is (h,k)
so as follows
y=(-2x^2+8x)-18
y=-2(x^2-4x)-18
y=-2(x^2-4x+4-4)-18
y=-2((x-2)^2-4)-18
y=-2(x-2)^2+8-18
y=-2(x-2)^2-10
vertex is (2,-10)
5.
vertex is the time where the speed is the highest
at about t=10, the speed is at its max
468 plus 624 times 7 divided by 4 and you should get the amount of water in the two tanks
Answer:98
Step-by-step explanation: the total of boxes the store has is 98 boxes of tiles. This is computed by dividing 56 by 7 which is equal to 392. Then 392 will be divided by 4 which will give us 98
