Answer:
y = (x-0)^2 + (-5) ⇒ y = x^2 - 5
Step-by-step explanation:
The general vertex form of the parabola y = a(x - h)² + k
Where (h,k) is the coordinates of the vertex.
As shown at the graph the vertex of the parabola is the point (0, -5)
So,
y = a(x-0) + (-5)
y = ax^2 - 5
To find substitute with another point from the graph like (1,-4)
So, at x = 1 ⇒ y = -4
-4 = a * 1^2 - 5
a = -4 + 5 = 1
<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>
Answer:
all i know is that number #2 is A
adding it all up is hard to figure out but #2 will show you that lay out so it mite be easier but i need help on this as well
Step-by-step explanation:
2/3= 0.6667 which you can figure out by 2÷3
3/4= 0.75 which you can figure out by 3÷4
because 0.75 is greater than 0.6667 she has enough to make the cake.
Lateral surface area, is the area that is not including bases
so it is an area of free rectangles
3*(5*8)=3*40=120 cm²
