perform the indicated operation (3 - 5i) - (-2 +11i)​

Answer:

y = 156

Step-by-step explanation:

The equation for direct variation is

y = kx

65 = k*5

Divide each side by 5

65/5 = k

13 =k

The equation is y = 13x

Let x = 12

y = 13*12

y = 156

Answer:

Oriental and American cockroach

Step-by-step explanation:

The question is not complete. The complete question is:

The length of the oriental, American and Australian cockroaches are 3.432 cm, 3.576 cm and 3.583 cm respectively. Scientist measured a Madeira cockroach and found it to be 3.438 centimeters long. Between which two cockroaches would the Madeira cockroach belong?

Answer: From the question, the Australian cockroach  is the longest cockroack with a length of 3.583 cm followed by the American cockroach of length 3.576 cm and lastly the Oriental cockroach of length 3.432 cm.

If the Madeira cockroach is to be placed, its length is greater than that of the Oriental cockroach but less than that of the American cockroach hence it would be placed between the Oriental and American cockroach. The lengths from lowest to highest is:

3.432 cm 3.438 cm 3.576 cm 3.583 cm

20[tex]x^{2}[/tex] + 109x -15

Step-by-step explanation:

12x * 5 = 60x

12x * 3x = 36x

12x * -2x= -24[tex]x^{2}[/tex]

-3 * 5 = -15

-3 * 3x = -9x

-3 * -2x = 6x

2x * 5 = 10x

2x * 3x =6x

2x * -2x= -4[tex]x^{2}[/tex]

60x + 36x -9x + 6x + 10x + 6x = 109x

24[tex]x^{2}[/tex] - 4

Represent your numbers as follows.

X ⇒ first number

X + 1 ⇒ second number

Since their sum is 91, we have x + (x + 1) = 91.

Solving from here, simplify on the left side to get 2x + 1 = 91.

Subtract 1 from both sides to get 2x = 90.

Now divide both sides by 2 and x = 45.

So if x = 45, then x + 1 must be 46.

So our numbers are 45 and 46.

Answer:

Total amount she need = $44,444

Step-by-step explanation:

Given:

Amount Michelle needs = $42,000

Real state commission = 5.5%

Find:

Total amount she need

Computation:

Assume,

Total amount she need = x

So,

Real state commission = 0.055x

So,

x - 0.055x = 42000

x (0.945) = 42,000

x = 44,444 (Approx)

Total amount she need = $44,444

Answer:

The point P on line AB such that the ratio of AP to PB is 2:1 is P = (0, 3)

Step-by-step explanation:

The dimension of the graph can be taken as 1 box = 1 unit

Therefore;

The coordinates of the point A = (-2, -7)

The coordinates of the point B = (1, 8)

For the a point P that gives the ratio AP to PB = 2:1 is given as follows;

The fraction of AP to AB = 2/(2 + 1)×AB = 2/3 × AB

Which gives;

The coordinate of the point P = (-2 + 2/3×(1 - (-2)), -7 + 2/3×(8 - (-7)))

P = (0, 3)

Therefore;

The coordinates of P such that the ratio of AP to PB is 2:1 is P = (0, 3).

Answer:

A: Linear

B: Linear

C: Linear

Step-by-step explanation:

So we have three functions:

[tex]f(x)=3x+1\\f(x)=x-6x+5\\f(x)=4x-x+1[/tex]

To determine the type of graph for each function, simplify each of them and then we can determine whether it's linear or quadratic.

1)

We have:

[tex]f(x)=3x+1[/tex]

This has a degree of 1. Quadratics have a degree of 2. In other words, quadratics have a x^2 term. There isn't one here, so this is a linear equation.

2)

We have:

[tex]f(x)=x-6x+5[/tex]

Simplify:

[tex]f(x)=-5x+5[/tex]

Again, this is of degree 1. There is no x^2 term. Thus, this is also a linear equation.

3)

We have:

[tex]f(x)=4x-x+1[/tex]

Simplify:

[tex]f(x)=3x+1[/tex]

This has a degree of 1. There is no x^2 term. Thus, this is also a linear equation.

Answer:

Step-by-step explanation:

a- f(x)=3x+1 it is linear equation

b: f(x)=x-6x+5

f(x)=-5x+5  linear equation

c: f(x)=4x-x+1

f(x)=3x+1  (linear equation)

(if there is no exponent then the graph is linear)

v = amount of salad Olivia ate

"Olivia ate twice as much as Reagan", meaning

amount Olivia ate = 2*(amount Reagan ate)

v = 2*r

v = 2r

2r = v

Answer:

[tex]\approx 2\ miles[/tex]

Step-by-step explanation:

Difference of 10 seconds between the lightning flash and its thunder clap.

Given that the speed of light is infinite.

So, lightning will be seen at the same time it happens.

10 seconds is the time taken by the sound to reach to the person.

Time taken = 10 seconds

Speed of sound = 1080 ft/sec

To find:

Distance from lightning flash in miles.

Solution:

First of all, let us a have a look at the formula:

[tex]Distance = Speed \times Time[/tex]

Putting the given values:

Distance = [tex]1080\times 10 = 108000\ feet[/tex]

5280 feet = 1 mile

1 feet = [tex]\frac{1}{5280}[/tex] miles

10800 feet = [tex]\frac{1}{5280}\times 10800 \approx 2\ miles[/tex]

$5,675

Step-by-step explanation:

you would just take 4% and 5% of 2500 which is 100 and 125 and multiply them both by 3 which is 300 and 375 and add them both to the 2500 which is 2800 and 2875 and since it asks for the sum you would add then to get a total of $5,675

A plane extends infinitely in two-dimension and it does not have a boundary

The error is in designating rectangles which are bounded planar shape as an whole plane

The reason for the error stated above is as follows:

Missing part of question: The drawing of the question that appear missing is attached

The definition of a plane in mathematics is an infinitely long and wide two-dimensional surface that has no thickness and which is defined by either;

The given figure is the diagram of two rectangles which are planar shapes enclosed by four straight line boundaries each of which are located in their respective planes that extends infinitely and are not entire planes by themselves

Therefore, the error is that a bounded planar figure is taken as being an infinite plane

Answer:

29090

Step-by-step explanation:

First of all, we will have to calculate the volumes of a soft ball and the volume of box.

Then we will divide the volume of box with volume of softball to find the number of balls that can be stored in the box.

Diameter of softball = 3.8 in

Radius of softball = 1.9 in = 0.158 ft

Volume of a sphere = [tex]\frac{4}{3}\pi r^3[/tex]

[tex]\Rightarrow \dfrac{4}{3}\pi (0.158)^3=0.0165\ ft^3[/tex]

Volume of cuboid box = Length [tex]\times[/tex] Width [tex]\times[/tex] Height = 6 [tex]\times[/tex] 10 [tex]\times[/tex] 8 = 480 [tex]ft^3[/tex]

Number of softballs that can fit inside the storage = [tex]\frac{480}{0.0165}[/tex] = 29090
