Answer:

13 years.

Step-by-step explanation:

I don't understand the original equation you entered, so I'm going to use another one.

[tex]A = A_0e^k^t[/tex]

Where A = initial population

A₀ = current population

e = Euler's constant

k = rate of decrease

t = time in years

Let's start off with what we know.

Today there are 800 fish left:

A₀ = 800

There were 1800 fish 5 years ago:

t = -5

A = 1800

The equation now looks like [tex]1800=800e^-^5^k[/tex]

First we find the rate of decrease.

[tex]\frac{1800}{800} = e^-^5^k[/tex]

⇒ [tex]2.25 = e^-^5^k[/tex]

⇒ [tex]ln(2.25) = -5k[/tex]

⇒[tex]\frac{ln(2.25)}{-5}[/tex]=k

⇒ k = -0.1621

The question asks when it will drop below 100, so make it equal to 100.

⇒[tex]100=800e^-^0^.^1^6^2^1^*^t[/tex]

⇒[tex]100/800=e^-^0^.^1^6^2^1^*^t[/tex]

⇒[tex]ln(1/8)=-0.1621*t[/tex]

⇒[tex]\frac{ln(1/8)}{-0.1621}[/tex] = t = 12.821

To the nearest year this is 13.

tan(x) = cot(x)

tan(x) = 1 / tan(x)

tan²(x) = 1

tan²(x) - 1 = 0

(tan(x) - 1) (tan(x) + 1) = 0

tan(x) - 1 = 0   or   tan(x) + 1 = 0

tan(x) = 1   or   tan(x) = -1

x = π/4 + nπ   or   x = -π/4 + nπ

where in both cases, n is any integer.

In the interval 0 < x < π, we get solutions:

• x = π/4 from the first family (when n = 0)

• x = 3π/4 from the second family (when n = 1)

So the equation has solutions x = π/4 or x = 3π/4.

Answer:

22.5

Step-by-step explanation:

How do you solve this question?

In order to find this answer, you must multiply the number given (30) by the percentage (75%). 75% is equal to .75. So, if you multiply 30 and 75%, you will get 22.5.

Answer:

The parallel line should be y = 2x + 7

The equation of the line that passes through the point (8,-1) and is parallel to the line y = 2x – 4 is; y = 2x + 7

An equation is an expression that shows the relationship between two or more numbers and variables.

Given If the line is parallel to the line resembling the equation y = 2x - 4, it would mean that the line would have a similar slope,

m= 2

We know that Point-Slope Form:

y - y₁ = m(x - x₁)  

Point  (-2,3)

Then Slope m = 2

Now Write the equation as;

y - 3 = 2(x + 2)

This means the final equation is;

y = 2x + 7

About 13.32 Pounds

Step-by-step explanation:

First. take the total weight of the three boxes and divide it by the number of boxes.

10/3 = 3.33 and so on

Now we know each box ways 3.33 pounds.

Now multiply 4 boxes by 3.33 pounds.

4 x 3.33 = 13.32

So the answer should be about 13.32 pounds.

Answer: 0.393 ; 0.9933

Step-by-step explanation:

Given that :

Mean lifetime follows an exponential distribution (m) = 6

a. What is the probability that the CPU fails in the next three years?

Using the poisson distribution formula :

1 - e^-λt

λ = 1/m = 1 / 6 = 0.1667

Probability of failure in next 3 years :

P(X < 3) = 1 - e^-λx

P(X < 3) = 1 - e^-0.1667*3

P(X < 3) = (1 - e^-0.5)

P(X < 3) = 1 - 0.6065306

P(X < 3) = 0.3934693

= 0.3935

b. Assume that your corporation has owned 10 CPUs for three years, and assume that the CPUs fail independently. What is the probability that at least one fails within the next three years?

Number of pc owned = 10

CPU failure is indepndent

Probability of atleast one fails :

1 - P(X ≥ 3)^n

P(X ≥ 3) = 1 - P(X < 3)

P(X ≥ 3) = 1 - 0.3935 = 0.607

Hence,

1 - P(X ≥ 3) = 1 - 0.6065^10

1 - P(X ≥ 3) = 1 - 0.0067345

1 - P(X ≥ 3) = 0.993265

= 0.9933

The hundreths place is the second digit to the right of the decimal point.

Since the number in the thousandths place is less than 5, the number in the hundreths place will remain as 9.

If the digit in the thousandths place had been 5 or greater, the answer would have been 11.20, as you would round the 9 up, consequently rounding the tenths place as well.

Answer:

A. (1/2)(4+i)= 2+ (1/2)i

Step-by-step explanation:

The equation 1/2(4+i) = 2+(1/2)i is the transformation if we multiply the complex number 4 + i with 1/2 option first is correct.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have a complex number:

= 4+i

Multiply it by 1/2

[tex]= \rm \dfrac{1}{2}(4+i)\\\\\rm =2+ \dfrac{1}{2}i[/tex]

[tex]\rm \dfrac{1}{2}(4+i) =2+ \dfrac{1}{2}i[/tex]

Thus, the equation 1/2(4+i) = 2+(1/2)i is the transformation if we multiply the complex number 4 + i with 1/2 option first is correct.

Answer:

  see below

Step-by-step explanation:

Dilation changes the distance to the center of dilation by a factor equal to the scale factor.

Part A:

Point R is 2 grid squares left and 6 grid squares down from the center of dilation at (3, 7). So, point R' will be (3/2)(2) = 3 grid squares left and (3/2)(6) = 9 grid squares down from that center.

Likewise, point T is 2 square diagonals down and right of (3, 7), so T' will be 1 more square diagonal farther.

__

Part B:

As in Part A, the scale factor multiplies the distance from the center of dilation. L will be the midpoint between R and (-1, 9); M will be the midpoint between T and (-1, 9).

Answer:A

Step-by-step explanation:

Since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.

A linear equation is in the form:

y = mx + b;

where m is the slope, b is the y intercept and y, x are variables.

Since f(0) = 14, hence the y intercept is 14, hence the graph passes through point (0, 14).

Also, since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.

Answer:

13.29 inch

Step-by-step explanation:

Given:

Square game board.

Area of square game board = 175 sq inch

To find:

The side length of the square board game.

Solution:

First of all, we need to know the formula for area of a square.

Let us have a look at the formula for area of a square.

[tex]Area = Side\times Side[/tex]

OR

[tex]Area = Side^2[/tex]

Putting value of area = 175 sq in and let us find the value of Side.

[tex]175=Side^2\\\Rightarrow Side = \sqrt{175}\\\Rightarrow Side \approx \bold{13.29\ inch}[/tex]

Therefore, the answer is:

The appropriate side length of the square game board = 13.29 inch
