Answer 1

Answer: B

I took the edge test

Step-by-step explanation:

Answer 2

The location of the complex number 5 - 2i will be (5, -2) which is point D. Then the correct option is D.

What is a complex number?

The complex number is the combination of the real part and the imaginary part. Then the complex number is given as a+bi where the value of i is √(-1) and the value of i² is -1.

The complex number is given below.

⇒ 5 - 2i

The real part represents the x-axis and the imaginary part represents the y-axis. Then the location of the complex number is written as,

⇒ (5, -2)

The location of the complex number 5 - 2i will be (5, -2) which is point D. Then the correct option is D.

Step-by-step explanation:

144+65=209

Answer:  174 square meters

==================================================

How to get that answer:

We have a 12 by 12 square of area 12*12 = 144 square meters.

Then on top of this we have a triangle with base 12 and height 5, so its area is base*height/2 = 12*5/2 = 60/2 = 30 square meters

Overall, the two areas combine to 144+30 = 174 square meters

---------

Side notes:

The missing side of the triangle can be found through the pythagorean theorem. You could use the trapezoid area formula as an alternative path, instead of finding the area of each smaller piece.We can condense the unit "square meters" into "sq m" or "m^2".

c) The growth factor per days is 1.08

e) The growth factor per hour is 1.08^{1/24}

Step-by-step explanation:

Given the following data;

P(d) = 10 * 1.08^{d} in thousands.

a. To find the number of insects on day 1;

Day, d = 1

[tex] P(d) = 10 * 1.08^{d} [/tex] ......equation 1

Substituting into the formula, we have;

[tex] P(1) = 10 * 1.08^{1} [/tex]

[tex] P(1) = 10 * 1.08 [/tex]

[tex] P(1) = 10.08 [/tex]

Therefore, option (a) and (b) are incorrect.

c. To find the growth factor per day;

An exponential function is given by the formula;

[tex] y = mg^{x} [/tex] .....equation 2

Where;

g is the growth factor of a population.

Comparing eqn 2 with eqn 1;

g = 1.08

Therefore, option (c) is correct.

e. To find growth factor per hour;

From equation 1 above;

[tex] P(1) = 10 * 1.08^{\frac {1}{2}} [/tex]

Therefore, option e is correct.

A distance of 400 km is represented in the map by 3 cm. What is the distance between two towns if they are 7.5 cm apart in the map?​

Answers

Answer:

The distance between the two towns is of 1000 km.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

We have that:

3 cm represents a distance of 400 km.

What is the distance represented by 7.5 cm?

3 cm - 400 km

7.5 cm - x km

Applying cross multiplication:

[tex]3x = 400*7.5[/tex]

[tex]x = \frac{400*7.5}{3}[/tex]

[tex]x = 1000[/tex]

The distance between the two towns is of 1000 km.

You play a game in which two dice are rolled. If a sum of 7 appears, you win ten dollars; otherwise, you lose two. If you intend to play this game for a long time, should you expect to make money, lose money, or come out about even? Explain.

Answers

Answer:

Come out even

Step-by-step explanation:

The total numbers of faces in rolling two dice = 6 X 6 = 36

The sum of appears in the following cases: {6, 1}, {1, 6}, {2, 5}, {5, 2}, (3, 4}, {4, 3}. Making a total of 6 cases

Probability of obtaining a sum of 7 = possible number of cases where the sum of 7 appears ÷ total number of outcome

= 6/36 = 1/6

Probability of not obtaining a sum of 7 = 1 - Probability of obtaining a sum of 7

= 1 - 1/6

= 5/6

Expected Value: (1/6)10 + (5/6)(-2) = (10-10)/6 = 0

So the answer is come out even

Step-by-step explanation:

Independent events:

Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

Thus, P(A and B)=P(A)•P(B) is used when two events are independent.

Find the volume of a sphere with a radius of 9 inches. Use 3.14 for π. Round your answer to the nearest tenth..

Answers

Answer: 3053.6 in^3

To find the volume of a sphere, you first must identify the formula: (4/3)pi(r)^3

You’re given the radius 9 inches
And you’re also given the pi approximation 3.14.

With that in mind, we can plug those variables in the formula to get:
(4/3)(3.14)(9in)^3 = 3053.63 in^3

And rounded to the tenths place:

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 27 N acts on a certain object, the acceleration
of the object is 3 m/s?. If the force is changed to 18 N, what will be the acceleration of the object?
X
5
?

Answers

Solution :

It is given that force on the object is directly proportional to acceleration.

So, F = ka

Here, k is any constant value.

Putting, F = 27 N and a = 3 m/s² in above equation, we get :

3k = 27

k = 9 N s² m⁻¹

Putting, k in above equation, we get :

F = 9a

Now, putting F = 18 N, we get :

a = 18/9 m/s²

a = 2 m/s²

Hence, this is the required solution.

Step-by-step explanation:

Part B: Plot point C(2,7). If M is the midpoint of CD, what are the coordinates of D?

Answers

Answer:

[tex]D = (-4,-9)[/tex]

Step-by-step explanation:

Given

[tex]C =(2,7)[/tex]

 [tex]M=(-1,-1)[/tex]

Required

The coordinates of D

Represent D with:

[tex]D = (x_2,y_2)[/tex]

Using midpoint formula, we have:

[tex]M(x,y) = \frac{1}{2}(x_1 + x_2, y_1 + y_2)[/tex]

So, we have:

[tex](-1,-1) = \frac{1}{2}(2 + x_2, 7 + y_2)[/tex]

Multiply both sides by 2

[tex](-2,-2) = (2 + x_2, 7 + y_2)[/tex]

Compare both sides

[tex]2 + x_2 = -2[/tex]

[tex]7 + y_2 =-2[/tex]

In [tex]2 + x_2 = -2[/tex], we have:

[tex]x_2 =-2-2[/tex]

[tex]x_2 =-4[/tex]

In [tex]7 + y_2 =-2[/tex], we have:

[tex]y_2 = -2 - 7[/tex]

[tex]y_2 = -9[/tex]

So, the coordinates of D is:

[tex]D = (x_2,y_2)[/tex]

[tex]D = (-4,-9)[/tex]
