Answer:

So x=4 and y=-5 would work.

Step-by-step explanation:

When you multiply complex conjugates, you get a real result.

Example:

[tex](a+bi)(a-bi)=a^2-b^2i^2=a^2+b^2[/tex]

I replace [tex]i^2[/tex] with -1 since [tex]i^2=-1[/tex].

[tex]a^2+b^2[/tex] is a real number (there is no imaginary part, no i).

So what is the conjugate of 4+5i?

4-5i

So x=4 and y=-5 would work.

A multiple of the complex conjugate would work as well.

[tex](a+bi)(ca-cbi)[/tex]

[tex]c(a+bi)(a-bi)[/tex]

[tex]c(a^2-b^2i^2)[/tex]

[tex]c(a^2+b^2)[/tex]

This is still a real number; there is no imaginary part,no i.

Answer:

Option C is correct

Step-by-step explanation:

The two triangles are similar if there sides are proportional to each other

So, In Triangle ABC and Triangle DEF

AB/DE=BC/EF=AC/FD

according to definition of similar triangles.

We are given AC = 8

and FD = 4

So, AC/FD = 8/4 = 2/1

or 2:1

So, Option C is correct

Answer: Option C

2:1

Step-by-step explanation:

Two triangles are similar if the ratio of their sides is proportional.

In this case we have the triangle ∆ABC and ∆DEF so for the sides of the triangles they are proportional it must be fulfilled that:

[tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}[/tex]

In this case we know that:

[tex]AC=8[/tex]

[tex]DF=4[/tex]

Therefore

[tex]\frac{AC}{DF} = \frac{8}{4}\\\\\frac{AC}{DF} = \frac{2}{1}[/tex]

The similarity ratio of ∆ABC to ∆DEF is 2:1

Answer:

[tex]log_{3}(x-4)= 3log_{3}(2)[/tex]

Step-by-step explanation:

The given equation is:

[tex]x-4=2^{3}[/tex]

We have to find the logarithmic equation with same solution as the given equation.

If we take the log of both sides, we can get a logarithmic equation. Since the log operation is applied to both sides the solution of the equation will stay the same.

Taking the logarithm to the base 3 of both sides, we get:

[tex]log_{3}(x-4)= log_{3}(2)^{3}\\\\ log_{3}(x-4)= 3log_{3}(2)[/tex]

Answer: The CORRECT answer is C: log2(x-4)=3

Answer:

A) 41 laps

Step-by-step explanation:

Round 17 4/7 to the nearest whole number:

18

Round 23 5/14 to the nearest whole number:

23

18 + 23 = 41

Final answer:

By rounding the fractional laps to the nearest whole numbers (18 for Monday and 23 for Wednesday), and adding them together, we estimate that Kira swam a total of 41 laps. Option A is the closest answer.

Explanation:

To estimate the total number of laps Kira swam on Monday and Wednesday, we should round the numbers to the nearest whole number and then add them together. Kira swam 17 4/7 laps on Monday, which we can round to 18 laps for estimation purposes. On Wednesday, she swam 23 5/14 laps, which rounds to 23 laps. Adding the estimated numbers together, we get:

Monday: 18 (estimated from 17 4/7)

Wednesday: 23 (estimated from 23 5/14)

Therefore, the estimated total number of laps is 18 + 23 = 41 laps.

The closest answer to our estimation is Option A: 41 laps.

Answer:

n=5   n=9

Step-by-step explanation:

n^2 − 14n = -45

Add 45 to each side

n^2 − 14n +45 = -45+45

n^2 -14n +45 = 0

Factor the equation

What 2 number multiply to 45 and add to -14

-5*-9 = 45

-5+-9 = -14

(n-5) (n-9) =0

Using the zero product property

n=5   n=9

Answer: 7,920 feet.

Step-by-step explanation: There are 5,280 feet in a mile. To find how many feet are in 1.5 miles, multiple 1.5 by 5,280.

1.5 x 5,280 = 7,920

There are 7,920 feet in 1.5 miles.

The measure of <2 is 45 degree.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is always 180 degrees.

From the figure, applying angle sum property

<2 + 45 + 90= 180

<2 + 135=180

<2 = 180- 135

<2 = 45 degree

Thus, the measure of <2 is 45 degree.

Answer:

x=65

Step-by-step explanation:

The angle with the measurement of 125 degrees is supplementary to the one adjacent to it (sharing the same vertex and on same line).

What that means is that the measurement of the angle adjacent to that angle of 125 degrees is 180-125=55.

So now we know the sum of the interior angles of a triangle add up to be 180 degrees.

That is we have to solve the following equation for x:

x+55+60=180

Add 55 and 60:

x+115=180

Subtract 115 on both side:

x=180-115

Simplify:

x= 65

Step-by-step explanation:

Quadratic Function is a polynomial which has a maximum degree of 2. It is expressed in the form:

f(x) = a + bx + cx^2; where a, b, and c are real numbers.

Any function which has the highest degree of 2 (not more than that) is the quadratic function. Option A illustrates the absolute values function. Option B shows a function which does not match the characteristics of the quadratic equation. Option D shows a linear function. Therefore, Option C (i.e. f(x) = x^2) is the correct choice!!!

Answer:

3/5

Step-by-step explanation:

Soh Cah Toa

In some trigonometry classes, this acronym is very important to solving questions like this.

Why?

It tells us the right triangle-definition of these trigonometry functions.

We have that cosine of an angle is equal to tge side that is adjacent to it over the hypotenuse.

So here we are asked to find cos(B).

Lets look at triangle respect to the angle B

The measurement of the side that is opposite is 64.

The measurement of the side that is adjacent is 48.

The measurement of the hypotenuse is 80.

So cos(B)=48/80.

Let's reduce. 48 and 80 have a common factor of 8 so divide numerator and dexter by 8. This gives us:

cos(B)=6/10.

One more step in reducing. Both factors are even so cos(B)=3/5.

Answer:

12 miles per hour

Step-by-step explanation:

Let her normal rowing speed be x

Also note the formula D = RT, where d is distance, R is rate(speed) and T is time

On windy day, her speed is x + 4

On against wind return, her speed is x - 4

With wind, she can go 48 miles in same amount of time when she goes 24 miles against wind. This can be written as:

48 = (x+4)T

24 = (x-4)T

We can write each equation in terms of T and equate both. So we have:

48/x+4 = T

24/x-4 = T

Thus,

[tex]\frac{48}{x+4}=\frac{24}{x-4}\\48(x-4)=24(x+4)\\48x-192=24x+96\\24x=288\\x=\frac{288}{24}\\x=12[/tex]

Thus, Jaime's normal rowing speed is 12 miles per hour

Answer:

[tex]3 \le x \le 7[/tex].

Step-by-step explanation:

Hopefully this will help. Let me know in the comments if it doesn't.

The domain is all the x's where the function exists. The function you have starts at x=3 and ends at x=7. There are no breaks in your line between those numbers for x. So your domain is all x's between 3 and 7 ( inclusive).

So that means all values of x that is greater than or equal to 3 and values of x less than or equal to 7.

The answer is 12 miles, if every inch is 3 miles on the map then 3x4=12.

Answer:

12 miles

Step-by-step explanation:

In order to solve the problem you only have to use the scale of the map, we know that the ratio is 1 inch to 3 miles, so if one inch in the map represent 3 miles on real scale, now we just do a rule of three like this:

[tex]\frac{1 inch}{4 miles}=\frac{3 inches}{x}[/tex]

So now that we have our function we can clear the x to solve the problem:

[tex]x=\frac{3x4}{1}[/tex]

[tex]x=\frac{12}{1}[/tex]

[tex]x=12 miles.[/tex]

By doing this we now know that there are 12 miles from downtown to the lake.

Step-by-step explanation:

In the given question we have (4y-8) divided by 2

which can be written mathematically as [tex]\frac{\left ( 4y-8 \right )cm}{2}[/tex]

Now (4y-8) is a quatity  with unit cm. and the whole expression is in parentheses. Moreover, two quatity can only be added or subtracted only when their units are same. Therefore 4y and 8 must have same unit that is cm.
