Answer:
1686.22
Step-by-step explanation:
2300=P(1+(0.052x7))
2300=P1.364
P=2300/1.364
=1686.217...
=1686.22...
=1686 FOR THE NEAREST DOLLAR
Answer: 18°F
Step-by-step explanation: if you add 21 and -3 you get 18
I leaerned this neat trick
you don't need to convert to vertex form
where
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by inserting the x value of the vertex into the equation
so
1x^2-6x+14
-b/2a=-(-6)/2(1)=6/2=3
plug that in
y=x^2-6x+14
y=3^2-6(3)+14
y=9-18+14
y=5
the vertex is (3,5)
4x + 3x = 28
7x = 28
7x/7 = 28/7
X = 4
Girls = 4
4x4 = 16
16 girls
Consecutive terms differ by 3, so

Since the first term is

, the formula for the sequence is
