Given equation is
To find the x coordinate of vertex we use formula
From the given equation a= 2, b= 8 and c= -5
Plug in all the values
The x coordinate of vertex is x=-2
To find y coordinate of vertex we plug in -2 for x in the given equation
So vertex is (-2,-13)
Answer:
-4.5
Step-by-step explanation:
If we substitute 10 for t we get the height of the balloon after being in the air 10 minutes
h(10) = 210 - 15(10) = 210 - 150 = 60
Answer:
204kg
Step-by-step explanation:
New percentage = 100% - 15%

so 100 - 15 = 85%
85% as a decimal = 0.85
To find the new amount, we have to multiply
240 x 0.85 = 204
Remember to add kg
Answer - 204kg
