What is the vertex of this
quadratic function?
y = 4(x-3)2 – 8

The vertex of is at .

Step-by-step explanation:

Consider a quadratic function with the point as the vertex (for some constants and .) It would then be possible to express this function in the vertex form for some constant where . (Note the minus sign in front of .)

For example, the quadratic function in this question is expressed in this vertex form:

.

The values of and are and , respectively. Thus, the vertex of this parabola would be at the point .

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The solution is in the following image

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales
