Answer:
Step-by-step explanation:
hello :
f(x) = a(x - h)²-k ....vertex form when the vertex is : (h,k)
h=1 and k=0 so : f(x) = a(x-1)²
a parabola that passes through the point (2,8) : f(2)=8
a(2-1)² =8
a= 8
f(x) = 8(x-1)²= 8(x²-2x+1)
f(x) 8x²-16x+8 .....standard form
( x + 5 i ) ( x − 5 i )
Multiply the constant by − i ^2 and factor.
Answer: 7/21 for blue and 6/21 for yellow. so 7/14
The answer is "It was A Jab Well Done" You have to finish the whole sheet to get the answer
Amount of tax paid = 43-40 = 3
Tax rate = 3/40 = 0.75
0.75 x 100 = 7.5%
Tax rate = 7.5%
B
K=1/3=10
L=1/5=6
10+6=16
30-16=14
