Answer:
These are all equivalent to the ratio of 1:2
Step-by-step explanation:
Standard Form : f (x) = a(x - h)2 + k
Where in this equation (H,K) is the vortex of the parabola
<u>and there are four other ways to solving these quadratic</u>
1. Factoring
2. Completing the square
3. Your quadratic formula ( f (x) = a(x - h)2 + k )
4. Graphing
<h3><u>
Answer:</u></h3>
<u>Option A (Yes because 3 x 2 = 6 and 14 x 2 = 28.) is correct.</u>
<h3><u>
Step-by-step explanation:</u></h3>
<u>This is because if we simplify 3/6 and 14/28, both of them will get 1/2. This means that only A and C are possible.</u>
- => Option A is correct because 3 x 2 does equal 6 and 14 x 2 does equal 28.
- => Option C is incorrect because 3 x 5 does not equal 14 and 6 x 5 does not equal 28.
Hoped this helped.

compound interest equation for annually compounded

A=final amount
P=principal
r=rate in decimal
t=time in years
given that
A=1550
P=1000
r=5.5%=0.055
find t

divide both sides by 1000

take ln of both sides

use ln rule 

divide both sides by ln(1.055)

using a calculator, we get that t=8.18544 yrs
so about 8.2yrs
To do this you must combine like terms as follows.
7x + 6x = 13x
7 - 9 = -2
Combine these together and you will get the following.
13 - 2 or -2 +13
