A population numbers 19,000 organisms initially and grows by 4.8% each year. Suppose P represents population and t represents th
V125BC [204]

Answer:

The exponential model for the population is P(t) = 19000e^{0.048t}

Step-by-step explanation:

The exponential model for the population has the following format:

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

In which P(0) is the initial population and r is the growth rate, as a decimal.

A population numbers 19,000 organisms initially and grows by 4.8% each year.

This means that P(0) = 19000, r = 0.048

So

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

P(t) = 19000e^{0.048t}

The exponential model for the population is P(t) = 19000e^{0.048t}

Solve -2/3 and x- intercept 5
lions [1.4K]

Answer:

y= -2/3x+10

Step-by-step explanation:

-2/3=slope, x-intercept=5 = (5,0)

formula is y-y1=m(x-x1)

(5,0) ---> 5=x1 0=y1

y-0= -2/3(x-5)

y-0= -2/3x+10

+0           +0

y= -2/3x+10

If the mean is 4, what is the missing number of the data set: 3, 4, ___, 7, 2, 1.
kodGreya [7K]

Answer:

7

Step-by-step explanation:

Let the missing number of the data be x.

\because mean =  \frac{3 + 4 + x + 7 + 2 + 1}{6}  \\  \\ \therefore 4 = \frac{17 + x }{6}  \\  \\ \therefore 4 \times 6 = 17 + x \\  \\ \therefore 24 - 17 = x \\  \\\therefore x = 7

Thus, the missing number of the data is 7.

What is the measure of angle x? A pair of parallel lines is cut by a transversal. An exterior angle on the left of the transvers
NNADVOKAT [17]
As we can observe,
Angle x and 40° forms a linear pair.

so,
x+40 = 180
x = 140°

Measure of Angle x will be 140°.
