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

The formula, P=V^2/R,gives the relationship between resistance (R), voltage (V) and power (P). Solve the formula for Voltage

riadik2000 [5.3K]

Start by multiplying both sides by R to isolate V².
V² = P·R

Now, take the square root of both sides to get V.

V = √PR

Jack has some marbles. He has ten more red marbles than blue marbles. He has fewer yellow marbles than blue marbles.

kap26 [50]

Answer:

<u>Jack has at least 15 marbles: 12 red, 2 blue and 1 yellow.</u>

Step-by-step explanation:

1. Let's review the information given to us to solve the problem correctly:

Number of red marbles = 10 more than blue marbles

Number of yellow marbles fewer than blue marbles

2. How many of each color marble could Jack have?

r = Number of red marbles

b = Number of blue marbles

y = Number of yellow marbles

r = b + 10

y < b

If y = 1, then b ≥ 2, and r = b + 10,

fulfilling the three conditions, we have:
