Hi!
(x+a)·(x+b) = x²+xa+xb+ab = x²-12x-45
x² = x²
xa+xb = (a+b)x = -12x ⇒ (a+b) = -12
ab = -45
When (a+b) = -12 and ab = -45?
+3-15 = -12 and (+3)(-15) = -45
-3-15 = -18 and (-3)(-15) = +45
+3+15 = +18 and (+3)(+15) = +45
-3+15 = +12 and (-3+15) = -45
Answer:
(x+3)(x-15)
Answer:
s(t) = 10000·1.65^t
Step-by-step explanation:
The general form of an exponential model is ...
f(t) = (initial value) × (1 +(fractional change))^t
where the fractional change can be positive or negative and t is the number of time units. Each time unit will correspond to the period required for the fractional change.*
__
For your problem, you have (initial value) = 10,000 and (fractional change) = 65% = 0.65 with time units of 1 year. Your function for sales (s) will then be ...
s(t) = 10000·1.65^t
_____
* The business regarding time units has to do with problems where you get a description like "increased 30% in 4 hours." Then, if t is in hours, the multiplier of the initial value looks like 1.30^(t/4).
The question is an illustration of equivalent ratios.
- 3 cups of dark orange require 3 ounces of yellow paint
- 3 cups of light orange require 19.5 ounces of yellow paint
1 cup of dark orange requires
To make 3 cups, we simply multiply by 3, because 
So, we have:
2 cups of light orange require
To make 3 cups, we simply multiply by 1.5, because 
So, we have:
Hence:
- 3 cups of dark orange require 3 ounces of yellow paint
- 3 cups of light orange require 19.5 ounces of yellow paint
