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>
2.86 the negatives will cancel it self den u divide it
Answer:
Surface Area=208 cm²
Step-by-step explanation:
Surface Area= 2×l×w+2×l×h+2×h×w
SA= 2×11×4+2×4×4+2×11×4=208
The best way is to do problems over and over again and making mistakes with them.There is no point in doing them if you get correct answers.
When you make mistakes you ask someone what’s wrong and try not to make that mistake again.
That’s how I became a master at maths and physics.
As for help with calculus the important thing is to understand how graphing works.
Once you got that do more questions.
So basically to summarise make mistakes don’t repeat and find out how it works
Hope this helps:)
