3⁽ˣ+ ₂⁾ =10 . TO SOLVE USE LOG NEERIAN ln (which base =e)

e⁽ˣ⁺²⁾lⁿ⁽³⁾ =e¹⁰ [the exponent on the 1st e is (x+2)ln(3)]

(x+2)ln3=ln10
xln3 + 2ln3 = ln10
x.ln3 = ln10-2ln3 and x =(ln10-2ln3)/ln3 =(2.302585-2.097224)/1.098612
x= 0.095903

The fox population in a certain region has a relative growth rate of 4% per year. It is estimated that the population in year 20

Answer:

a) $P(t) = 17900e^{0.04t}$

b) The population estimated in 2008 is of 24651.

Step-by-step explanation:

The population growth model may be given by the following exponential function:

$P(t) = P_{0}e^{rt}$

In which P(t) is the population after t years, $P_{0}$ is the initial population and r is the growth rate.

(A.) Find a function that models the population t years after 2000 (t=0 for 2000)

We have that:

$P_{0} = 17900, r = 0.04$ . So

$P(t) = P_{0}e^{rt}$

$P(t) = 17900e^{0.04t}$

(B.) Use the function from part A to estimate the fox population in the year 2008.

2008 is 8 years after 2000. So:

$P(8) = 17900e^{0.04*8} = 24650.5$

The population estimated in 2008 is of 24651.

Charlie needs to make a total of 40 deliveries this week. So far he has completed 32 of them. What percentage of his total deliv

xz_007 [3.2K]

Answer:80%

Step-by-step explanation:

He needs to make 40 deliveries and he has allready done 32.

if 40 is the 100%

32 is 80%

Using Algebra:

40 - 100%

32 - x%

Therefore:

X%= 32*100%/40 = 80%

A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.

nlexa [21]

To find the length of a line given two points, we are going to use the distance formula, which is defined below:

$D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

( $(x_1, y_1)$ and $(x_2, y_2)$ are the two points)

The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:

$D = \sqrt{(-1 - 2)^2 + (5 - 5)^2$
