Answer:
y = 4(x + 2)^2 - 20.
or in standard form it is
y = 4x^2+ 16x - 4.
Step-by-step explanation:
The equation in vertex form will be:
y = a(x + 2)^2 - 20 where a is some constant.
The y-intercept is (0, -12) so:
-12 = a(0 + 2) - 20
2a = -12 + 20 = 8
a = 4.
The transformation of a base function,f (x) by the multiplication of a constant k where 0 <k <1
Answer:
5,280
Step-by-step explanation:
6600 x 20 = 132,000
132,000 / 100 = 1320
6600 - 1320 = 5280

Find what each banana costs by dividing the $15 dollars between the 10 bananas 15/10=$1.5 then times by 3 to get how much 3 bananas cost $1.5*3= $4.50
Answer:
$137,339.88
Step-by-step explanation:
Here is the equation for compound interest: A=P(1+(r/n))^nt
where A=amount of money, P=principal, r= rate in decimal, n=number of times compounded per t, and t=time
In this case:
A=$250,000
P= ?
r= 0.04
n= 12 month/yr
t= 15 yrs
You can manipulate the equation to solve for P:
P=A/[(1+(r/n))^nt]
Plug in variables then solve:
P= 
P=137339.8761 = $137,339.88
