Given an initial quantity Q0=150 and a growth rate of 7% per unit time, give a formula for the quantity Q as a function of time t, and find the value of the quantity at t=10.
a) Assume the growth rate is not continuous. Round your answer for Q(10) to three decimal places.
Q(t)=
Q(10) =
b) Assume the growth rate is continuous. Round your answer for Q(10) to three decimal places.
Q(t)=
Q(10)=

Answers

Answer:

Step-by-step explanation:

From the given information:

(a)

Since growth quantity is not continuous

[tex]Q(t) = 150 (1.07)^t[/tex]

For t = 10

[tex]Q(10) = 150 (1.07)^{10}[/tex]

[tex]\mathbf{Q(10) = 295.073}[/tex]

(b)

Here, for a continuous growth rate, the growth quantity can be computed in terms of initial quantity and the growth rate.

i.e.

[tex]Q(t) = 150 e^{0.07t}[/tex]

At t = 10 for a continuous growth rate;

[tex]Q(10) = 150 e^{0.07 \times 10}[/tex]

[tex]Q(10) = 150 e^{0.7}[/tex]

[tex]\mathbf{Q(10) = 302.063}[/tex]

Answer

Answers

Answer:

[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}+C[/tex]

Step-by-step explanation:

I notice you have a dx at the end of the equation, this leads me to believe this is an integral. With no bounds of integration, I will solve for the indefinite integral. I will also interpret your equation as follows:

[tex]\int \:2+5x+\frac{1}{2}x^3dx[/tex]

Sum rule tells us:

[tex]\int \:2dx+\int \:5xdx+\int \frac{1}{2}x^3dx[/tex]

From this we get:

[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}[/tex]

Don't forget to add the constant!

[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}+C[/tex]

The difference of the square of a number and 10 is equal to 3 times that number. Find the negative solution.

Answers

Answer:

-2

Step-by-step explanation:

Let's call the number x. The statement tells us that

x^2 - 10 = 3x, or

x^2-3x-10 = 0

Factoring:

(x-5)(x+2) = 0. Here, we see that there are two solutions: x = 5 and x = -2. So, the negative solution is x = -2.

The equation of line WX is y = −2x − 5. Write an equation of a line perpendicular to line WX in slope-intercept form that contains point (−1, −2).

Answers

Answer:

Step-by-step explanation:

y = -2x - 5.....slope here is -2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we will need is : 1/2. See how I flipped the slope of -2/1 and changed it to -1/2.....now I change the sign making our new slope be 1/2.

y = mx + b

slope(m) = 1/2

(-1,-2).....x = -1 and y = -2

now sub and find b, the y int

-2 = 1/2(-1) + b

-2 = -1/2 + b

-2 + 1/2 = b

-4/2 + 1/2 = b

-3/2 = b

so ur perpendicular line is : y = 1/2x - 3/2

Answer:

y = -2x - 5

m = -2

Step-by-step explanation:

The perpendicular line has a negative reciprocal slope.

m = 1/2

You are also given a point, so use the point slope formula.

y - y1 = m(x - x1)

y + 2 = 1/2(x + 1)

y + 2 = 1/2x + 1/2

y = 1/2x - 3/2

So the line perpendicular to y = -2x - 5 in slope intercept form is:

y = 1/2x - 3/2

or

y = 0.5x - 1.5

The hypotenuse of a right triangle measures 15 cm and one of its legs measures 4 cm.
Find the measure of the other leg. If necessary, round to the nearestytenth.

Answers

Answer:

14.5 cm

Step-by-step explanation:

Pythagorean theorem: a^2 + b^2 = c^2

c = hypotenuse (15)

to solve for b (other leg), the equation is  b^2 = c^2-a^2

15^2 - 4^2 = 209

[tex]\sqrt{209}[/tex] = approx. 14.5

the other leg is (rounded to the nearest 10th) 14.5 cm

Consider the arithmetic sequence: 6,2,-2,-6,...
If n is an integer, which of these functions generate the sequence?
Choose all answers that apply:
a(n) = 10 – 4n for n > 0
b(n) = 10 – 4n for n > 1
c(n) = 18 - 4n for n > 2
d(n) = 14 - 4n for n > 3​

Answers

Answer: b(n)=10-4n for n >1

The function a(n) = 10 – 4n for n > 0 generates the given arithmetic sequence.

What is an arithmetic sequence?

"It is a number sequence with a common difference between successive terms."

For given example,

Given arithmetic sequence: 6, 2, -2, -6, . . .

Here, 2 - 6 = -4

-2 - 2 = -4

-6 - (-2) = -4

This means, the common difference is d = -4

If n is a positive integer, then the function a(n) = 10 - 4n (n > 0) generates given sequence.

For n = 1

⇒ a(1) = 10 - 4(1)

⇒ a(1) = 6

For n = 2,

⇒ a(2) = 10 - 4(2)

⇒ a(2) = 2

For n = 3,

⇒ a(3) = 10 - 4(3)

⇒ a(3) = -2

For n = 4,

⇒ a(4) = 10 - 4(4)

⇒ a(3) = -6

Therefore, the function a(n) = 10 – 4n for n > 0 generates the given arithmetic sequence.

A lumber yard has scrap wood for sale. One employee recorded the measurements for the lengths of 50 different wood boards. The median length was recorded as 47.78 inches and the IQR was recorded as 14.54 inches. Someone discovers the measuring tape used started at 5 inches instead of 0. This means that each piece of wood is actually 5 inches shorter than the value recorded by the employee. What is the updated IQR

Answers

Answer:

The updated IQR is 14.54.

Step-by-step explanation:

The interquartile range is given by the difference between the 75th percentile(value that is greater than 75% of the measures) and the 25th percentile.

This means that each piece of wood is actually 5 inches shorter than the value recorded by the employee.

This means that the length of each wood is less than 5. However, the difference between the 75th percentile and the 25th percentile will stay the same, since both were subtracted by 5.

The updated IQR is 14.54.

The updated IQR is 14.54.

Interquartile range:The interquartile range should be provided by the difference between the 75th percentile and the 25th percentile.Since IQR was recorded as 14.54 inches. So the updated IQR is 14.54.
