find the distance between the two points in simplest radical form.
(3,-8) and (8,4)

Answers

Answer:

Step-by-step explanation:

The way to find the distance between two points on the coordinate plane is to use the distance formula, which is basically a way of applying the Pythagorean Theorem.

The distance formula is [tex]\sqrt{(x_{1}- x_{2} )^2 + (y_{1}- y_{2})^2}[/tex]. Let's say the coordinate (3, -8) is (x1, y1) and the coordinate (8, 4) is (x2, y2). We can plug these values into the formula:

[tex]\sqrt{(3- 8 )^2 + (-8 - 4)^2}\\\sqrt{(-5)^{2} + (-12)^{2}} \\\sqrt{25+144} \\\sqrt{169} \\13[/tex]

So, the distance between the two points is 13.

Write a differential equation that models the given situation. The stated rate of change is with respect to time t. (Use k for the proportionality constant.) When an advertising campaign for a new product is introduced into a city of fixed population N, the rate of change of the number y of individuals who have heard about the product at time t is proportional to the number of individuals in the population who have not yet heard about the product.

Answers

The differential equation that models the given situation will be dy/dt = K(N - y).

How to compute the equation?

Let y = number of individuals who have heard about the product.

Let N - y = this who haven't heard about the product.

From the given statement, the rate for change will be t = dy/dt. Therefore, the differential equation that models the given situation will be dy/dt = K(N - y).

Colin borrowed some money at 7.16%/a compounded quarterly. Three years later, he paid $5000 toward the principal and the interest. After another two
he paid another $5000. After another five years, he paid the remainder of the principal and the interest, which totalled $5000. How much money
did he originally borrow?

Answers

Based on the calculations below, the amount originally borrowed by Colin is $10,006.67.

How do we calculate the original amount using PV formula?

To solve this question, the following present value (PV) formula will be used:

PVn = Pn / (1 + r)^n ........................... (1)

Where:

PVn = Present value of an amount paid in year n

P = Amount paid in year n

r = quarterly interest rate = 7.16% / Number of quarters in a year = 0.0716 / 4 = 0.0179

n = number of quarters = Number of years * Number of quarters in a year = Number of years * 4

Using equation (1), we can therefore proceed as follows:

PV3 = PV of $5,000 paid after three years = $5,000 / (1 + 0.0179)^(3 * 4) = $4,041.18

PV5 = PV of $5,000 paid after another 2 years (after 3 years + 2 years = 5) = $5,000 / (1 + 0.0179)^(5 * 4) = $3,506.45

PV10 = PV of $5,000 paid after another 5 years (after 3 years + 2 years + 5 years = 10) = $5,000 / (1 + 0.0179)^(10 * 4) = $2,459.04

Therefore, we have:

Original amount borrowed = PV3 + PV5 + PV10 = $4,041.18 + $3,506.45 + $2,459.04 = $10,006.67

2x – 3y = –30

Answers

Answer:

(-3, 8) is the solution

Step-by-step explanation:

The LCD of the first equation is (3)(4) = 12. Rewriting this equation, we get:

4x + 3y = 12

to which we add the second equation, obtaining:

4x + 3y = 12

2x - 3y = -30

-------------------

6x = -18

Dividing both sides by 6 yields x = -3

Substituting -3 for x in the first equation yields 4(-3) + 3y = 12, or

-12 + 3y = 12

Then 3y = 24 and y must be 8.

The solution to this system of linear equations is (-3, 8).

Answers

The expanded form of V(x) = x(9-2x) (11-2x) is V(x) = 4x^3 - 20x^2 + 99x

How to expand the expression?

The missing information in the question is to express V(x) in standard form

We have:

V(x) = x(9-2x) (11-2x)

Open the brackets

V (x) = x(99 - 2x - 18x + 4x^2)

Evaluate the like terms

V (x) = x(99 - 20x + 4x^2)

Expand

V (x) = 99x - 20x^2 + 4x^3

Rewrite as:

V(x) = 4x^3 - 20x^2 + 99x

Hence, the expanded form of V(x) = x(9-2x) (11-2x) is V(x) = 4x^3 - 20x^2 + 99x

No triangles are possible for Options B and D. One triangle is possible for options A, C, and E. Many triangles are possible for option F.

How to interpret Triangles?

For it to be a triangle, then it must have 3 vertices and 3 sides with the sum of 2 sides greater than the third side. Also, the sum of interior angles must be 180°.

A) Side lengths of the triangle are; 4 inches, 8 inches and 10 inches.

4 + 8 > 10. Thus, it is a triangle.

B) 60° + 40° + 90° = 190 ≠ 180°

Thus, no triangle is possible because the sum of the angles in triangle is 180°.

C) There are two sides are given and one angle. Thus, from SAS congruency theorem, one triangle is possible.

D) 7 + 5 = 12

There is no triangle possible because the sum of the two sides must be greater than the third side.

E) We are given two angles and one side. Thus, from the ASA Congruency Postulate, one triangle is possible.

F) 60° + 80° + 40° = 180°

There are three angles given, but no sides and so we can say that many triangles are possible.

How to determine the surface area?

From the net of the rectangular prism, we have the following dimensions:

Length = 4 inches

Width = 3 inches

Height = 10 inches

The surface area is calculated as:

Area = 2 * (Length * Width + Length * Height + Width * Height)

So, we have:

Area = 2 * (4 * 3 + 4 * 10 + 3 * 10)

Evaluate

Area = 164

What is the length of AC in the given triangle?

Answers

Answer: the answer is 126.6

Step-by-step explanation:

Answer:

AC ≈ 126.6

Step-by-step explanation:

The law of sines can be used to find the side length of interest in this triangle. It tells you ...

a/sin(A) = b/sin(B) = c/sin(C)

missing angle

In order to use the law of sines, we must have a side length and its opposite angle. Here, the angle opposite the given side is unmarked, so we need to compute it using the angle sum theorem.

A +B +C = 180°

A +85° +53° = 180°

A = 42° . . . . . . . . . . . . . subtract (85°+53°)

unknown side

Then side AC can be found from ...

AC/sin(B) = BC/sin(A)

AC = BC·sin(B)/sin(A) = 85·sin(85°)/sin(42°)

AC ≈ 126.547

The closest answer choice is 126.6.
