Answer:

2372 fish

Step-by-step explanation:

Given:

y = 14.08 • 2.08^x

where y represents the number of fish in a lake and x represents the year.

In order to predict the number of fish in year 7, just replace x = 7 in the above equation,  to get:

y = 14.08 • 2.08^(7)

y = 2371.6 ≅ 2372

Answer:

2372

Step-by-step explanation:

Filling in a 7 for x gives you

y=14.08(2.08)^7

Raise 2.08 to the power of 7 to get

y = 14.08(168.4392677) and multiply to get

y = 2371.62489

Since we cannot have a decimal amount of fish, the population will round to 2372 as a whole number

Nesterboy [21]

Answer:

m<LMN = 167°

Step-by-step explanation:

Given:

m<LMT = 23°

m<TMN = 144°

Required:

m<LMN

SOLUTION:

m<LMN = m<LMT + m<TMN (angle addition postulate)

m<LMN = 23° + 144° (Substitution)

m<LMN = 167°

Which expression is NOT equal to 125? (1 point)
DENIUS [597]
Choice 1:
= 5 * [5^3 / (2/5)]^2
= by looking at the equation, it's kinda not equal to 125

choice 2:
= [5^3 / 5^4]^-3
= 5^-9 / 5^-12
= 5^(-9 - -12)
= 5^3
= 125

choice 3:
= 5^-2 / 5^-5
= 5^(-2 - -5)
= 5^3
= 125

choice 4:
= 5 * 5^5/5^3
= 5 * 5^(5-3)
= 5 * 5^2
= 5^3
= 125

So the expression that is not equal to 125 is:
<span>5 times the quotient 5 cubed over two-fifths, raised to the second power</span>

Alborosie
If Eric wanted to walk 24,000 steps in 4 days, he would have to walk 6,000 steps each day (24/4=6). The correct answer would be the bottom answer as saying he has already walked 2 days it would be (y=-6,000(2)+24,000) this would simply out to (y=-12,000+24,000) and then (y=12,000).
