Answer:
Vertex form:
Standard form:
Step-by-step explanation:
A quadratic function in vertex form is where
is the vertex.
We are given .
Let's plug that in:
.
Now let's find .
We will use the -intercept
to find
.
So the function in vertex form is:
.
In standard form, we will have to multiply and combine any like terms.
Let's do that:
Answer:
Area of sector = 84.861
Step-by-step explanation:
Given
The radius of the circle = 9
central angle of sector =
value of pi π = 3.143
To find : the area of sector = ?
We know that the formula to calculate area of sector is given as:
area of sector = (π Θ)/
where, r is radius and Θ is the central angle of the sector
Substituting the known values in above formula, we get
area of sector = (3.143 x x
) /
= 84.861
Hence area of sector is 84.861
There are two scales that may be possible for this scale model; one where it's for every foot and one where it's for every meter.
The for every foot would be better to find out since the scale would be easier to use.
First, you have to divide each sided by 4.2, since you want to find how many meters for each foot.
For every 1 foot used in the model, the actual will be 125 meters.
1 ft = 125 m
