Answer:

8th year

Step-by-step explanation:

r > C

50(e^0.5t) > 1000(e^0.1t)

(e^0.5t)/(e^0.1t) > 20

e^(0.5t-0.1t) > 20

e^0.4t > 20

ln(e^0.4t) > ln20

0.4t × lne > ln20

t > ln(20)/0.4

t > 7.489330685

Population of rabbits first exceeds the population of crickets during the 8th year

Step-by-step explanation:

Start by finding when the populations become equal.

C = R

1000e^(0.1t) = 50e^(0.5t)

Divide both sides by 50.

20e^(0.1t) = e^(0.5t)

Divide both sides by e^(0.1t).

20 = e^(0.4t)

Take natural log of both sides.

ln 20 = 0.4t

Multiply both sides by 2.5

t = 2.5 ln 20

t ≈ 7.5

The population of Oak Forest is increasing at a rate of 4% per year. If the population is 39,410 today, what will it be in three

Nataly [62]

The population of Oak Forest is increasing at a rate of 4% per year.

Increase rate, r = 4%

Current population, P = 39,410

time, t = 3 years

Population after 3 years will be:
$P{(1 + \frac{r}{100} )}^{t} \\ \\ = 39410 \times { ( 1 + \frac{4}{100} )}^{3} \\ \\ = 39410 \times {1.04}^{3} \\ \\ = 44330.89 \\ \\ \approx \boxed{44331}$

Population after 3 years will be 44331

Riley makes a mistake in step 2 while doing her homework. What was her mistake? StartFraction x Over x squared minus 5 x + 6 End

kobusy [5.1K]

Answer:

The answer is:

She used the wrong common denominator

Step-by-step explanation:

Solving the given equation

$\frac{x}{x^2-5x+6}+\frac{x}{x+3}\\\\Step 1: \frac{x}{(x-2)(x-3)}+\frac{x}{x+3}\\Step2: \frac{x}{(x-2)(x-3)}+\frac{x(x-2)}{(x-2)(x+3)}\\Step3:\frac{x(x+3)+x(x-2)(x+3)}{(x-2)(x-3)(x+3)}$

Lets consider the steps given in the question:

$Step2: \frac{x}{(x-2)(x+3)}+\frac{3(x-2)}{(x-2)(x+3)}$

$Step3: \frac{x+3(x-2)}{(x-2)(x+3)}\\$

Lets compare both solutions:

In the original solution, the denominator of first term is (x-2)(x-3)

In the solution given in the question, the denominator of first term is (x-2)(x+3).

So the mistake she did in step 2 was that she change the sign of 3 in (x-3) from negative to positive, due to which she gets the wrong common denominator shown in Step 3.

Can someone help me with this question

weqwewe [10]

Step-by-step explanation:

In the given circle

$BC \cong BD$ (Radii of same circle)

$\angle BDC \cong \angle BCD.... (1)\\$

(angles opposite to congruent sides are congruent)

$\angle ABC$ is exterior angle of $\triangle BDC$

$m\angle ABC= m\angle BDC +m\angle BCD\\\therefore 124°= m\angle BDC+m\angle BDC\\.. [from\:(1)] \\\therefore 124°= 2m\angle BDC\\\\\therefore m\angle BDC= \frac{124°}{2}\\\\\therefore m\angle BDC= 62°\\\huge \pink {\boxed {\therefore m\angle ADC= 62°}} \\.. (\because A-B-D) \\$
