Answer:
- 20% decay
- 40% growth
- 80% decay
- 40% decay
- 60% growth
Step-by-step explanation:
The "growth factor" is the number that has an exponent. Subtracting 1 from that gives the growth rate. The growth rate can be expressed as a percentage by multiplying it by 100%. If it is negative, it represents a rate of decay.
For example, the growth factor of 0.8 is a growth rate of 0.8-1 = -0.2 = -20%, a decay of 20%.
__
Here, we'll list the growth factor and the rate of change:
growth factor ⇒ rate of change
0.8 ⇒ 20% decay
1.4 ⇒ 40% growth
0.2 ⇒ 80% decay
0.6 ⇒ 40% decay
1.6 ⇒ 60% growth
Sorry I don’t know that one but I recommend using the app photomath it really helps
Answer:
B) ( x+3)² - 5
Step-by-step explanation:
Given expression
x²+6x+4
Adding '9' and subtracting '9' of given expression
⇒ x² + 2 (3) (x) +(3)² -(3)² +4
(a + b)² = a² + 2 a b + b²
⇒ ( x+3)² - 9 +4
⇒ ( x+3)² -5
60° bc 25+35=60, 180-60=20, 180-20=60, 60+60+x=180; x=60
The train Chug-a-Lug must be going 153.5 miles to match the same speed as Old Steamy so they can arrive at the station at the same time.
