Answer:
13,250.0
When we multiply a number with 10, the decimal place of the original number will move to the right by one step.
Step-by-step explanation:
We can write the number 1,325 as 1325.00
Now, we have to solve the product of
So,
=
= 13,250.0 (Answer)
Therefore, when we multiply a number with 10, the decimal place of the original number will move to the right by one step and when we divide a number with 10, then the decimal place of the original number will move by one step to the left. (Answer)
Answer:
Vertex (-2.5,-300)
Step-by-step explanation:
We are given with h(t)=-16 t^2 +80 t. We are asked to find the vertex.
X-coordinate of vertex =
Where 'a' is coefficient of term
'b' is coefficient of 't' term.
From given function, a= -16
b=80
So,
x-coordinate of vertex =
=-2.5
y-coordinate of vertex =
Simplify it,
=-100 -200
= -300
So, vertex is at (-2.5, -300).
