ANSWER

[tex]W(\frac{9}{7},\frac{51}{7} )[/tex]

EXPLANATION

We want to find the coordinates of the point W(x,y) which divides V(-3,3) and X(9,13) in the ratio m:n=3:4.

The x-coordinate of this point is given by:

[tex]x= \frac{mx_2+nx_1}{m + n} [/tex]

[tex]x= \frac{3(9)+4( - 3)}{4 + 3} [/tex]

[tex]x= \frac{21 - 12}{4 + 3} [/tex]

[tex]x= \frac{9}{7} [/tex]

The y-coordinates is given by;

[tex]y= \frac{my_2+ny_1}{m + n} [/tex]

[tex]y= \frac{3(13)+4( 3)}{4 + 3}[/tex]

[tex]y= \frac{39+12}{4 + 3}[/tex]

[tex]y= \frac{51}{7}[/tex]

Hence

[tex]W(\frac{9}{7},\frac{51}{7} )[/tex]

Answer:

Step-by-step explanation:

Multiply corresponding components, then add the products:

[tex]v\cdot w=3(-4)+(-8)(-2)+(-3)(-6)=22[/tex]

The resultant of the dot product of two vectors is:

                     [tex]v\cdot w=22[/tex]

We are asked to find the dot product of the two vectors v and w.

The vectors are given by:

r = <8, 8, -6>; v = <3, -8, -3>; w = <-4, -2, -6>

This means that  in the vector form they could be written as follows:

[tex]r=8\hat i+8\hat j -6\hat k\\\\v=3\hat i-8\hat j -3\hat k\\\\w=-4\hat i-2\hat j -6\hat k[/tex]

Hence, the dot product of two vectors is the sum of the product of the entries corresponding to each direction component.

i.e. the x-component get multiplied to each other, y-component get multiplied to each other and so happens with z.

Hence, the dot product of v and w is calculated as:

[tex]v\cdot w=3\times (-4)-8\times (-2)-3\times (-6)\\\\i.e.\\\\v\cdot w=-12+16+18\\\\i.e.\\\\v\cdot w=22[/tex]

let's recall that in an isosceles triangle, the twin sides make twin angles at the bottom/base, so on the triangle on the left-side, if the "vertex" atop has an angle of 116°, then the twin sides below are simply 180° - 116 = 64, split that in half and that's 32° each.

The same is true for the isosceles triangle on the right side.  Also recall that a flat-line is always 180°, 32 + 72 + 76 = 180.

We can use a simple formula to solve for SST. The formula is:

[tex]SST=\frac{SSE}{1-R^2}[/tex]

Where

the coefficient of determination is  [tex]R^2[/tex]

Now, we are given  [tex]R^2[/tex]  is 0.25 and SSE is 12 (not SEA, it's SSE). we simply put it into the formula and solve for SST:

[tex]\\SST=\frac{12}{1-0.25}\\SST =16[/tex]

You can think of an inverse function as a function that “unwraps” x from whatever operations are attached to it. In the case of F(x) = √x, we can ”unwrap” x by squaring it. This narrows our options down to either A or D. Keep in mind that since there are no real number solutions to the square root of a negative number, we need to limit our domain to non-negative values. In other words, x ≥ 0. With that restriction, our answer is A.

The answer is:

The inverse of the given function is:

A. [tex]f(x)^{-1}=x^{2}[/tex]

Where,

[tex]x\geq 0[/tex]

Inversing a function involves inversing the function variables. If we want to inverse a function, we need to rewrite the variable "x" with "y" and rewrite the variable "y" with "x", and then, isolate the variable "y".

Also, the domain of the original function will be the range of its inverse function, and the range of the original function, will be the domain of the its inverse function.

We are given the function:

[tex]f(x)=\sqrt{x}[/tex]

[tex]f(x)=y=\sqrt{x}[/tex]

So, inversing we have:

[tex]y=\sqrt{x}[/tex]

[tex]x=\sqrt{y}[/tex]

[tex](x)^{2}=(\sqrt{y})^{2}\\\\x^{2}=(y^{\frac{1}{2}})^{2}\\\\x^{2}=y^{\frac{2}{2} }\\\\x^{2}=y[/tex]

So, we have that the given function is only "part" of its inverse function, since negative square roots does not exist, it means that the domain of the given function starts from the number 0 taking only positive numbers.

Hence, we have that the answer is:

A. [tex]F(x)=x^{2}[/tex]

Where,

[tex]x\geq 0[/tex]

14.(22) = 14.(20 + 2)

We still have 14 multiplying 22 but now it will multiply it by 20 and sum it after multiply by 2

So we have the distributive proppertie.

Answer:

distributive property.

Step-by-step explanation:

If you rewrite the problem 14(22) as 14(20+2) so that you can use mental math

22 is written as 20+2

so we got 14(20+2)

to multiply this we distribute 14 inside the parenthesis

we multiply 14 with 20 and then multiply 14 with 2

we are distributing 14 inside the parenthesis so its distributive property.

Answer:

"a period change"

Step-by-step explanation:

Simple ways of understanding transformations are:

Phase shift: 2 graphs would be shifted version of each other, all other things constant.

Period change: the 2 graphs would have different cycles, one would be compressed/stretched version of the other, all other things constant

Amplitude Change: The height/crest of the graphs would vary, that is the amplitude. All other things constant.

Addition of Negative constant: this would shift the 1 graph downwards with respect to the other graph, it is a vertical shift. All other things constant.

Now carefully looking at the 2 graphs given, we can see that the cycles are different. One is a more "relaxed", or "stretched" version of the other. This means, the period is changed.

Answer:

54.5 amps to the nearest tenth.

Step-by-step explanation:

V = IR  where V = volts, I = current and R = resistance.

12 = I * 0.22

I = 12/0.22

I = 54.5 Amps.

When the key is turned and the engine starts, the battery will supply approximately 54.55 amps to the engine.

The question regarding how many amps will be drawn from the 12-volt battery when a car engine with a resistance of 0.22 ohms is started can be solved using Ohm's Law. Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. The formula is given by I = V / R.

Therefore, the current drawn from the battery can be calculated as follows:

So, when the key is turned and the engine starts, the battery will supply approximately 54.55 amps to the engine.

Answer:

  82

Step-by-step explanation:

The sum resolves to ...

  13 + 18 + 23 + 28 = 82

_____

for n=2, the term is 5·2 +3 = 10+3 = 13

The coefficient of n is 5, so you know the next term will be 5 more than this:

for n=3, the term is 5·3 +3 = 15+3 = 18

Additional terms are each 5 more than the one before. Since there are so few terms, you can add them up directly as quickly as you can use any other formula. For a longer series, you might find the average term (here, 41/2), then multiply by the number of terms (here, 4). The result is the sum of the series:

  4·(41/2) = 82

Answer:

It is a right triangle.

Step-by-step explanation:

By the  Inverse Pythagoras Theorem if 39^2 = 36^2 + 15^2  then it is a right triangle.

39^2 = 1521

36^2 + 15^2 = 1296 + 225 = 1521.

So it is a right triangle.

Based on the converse of the Pythagorean Theorem, the triangle with the following side lengths is a right triangle.

What is the Converse of the Pythagorean Theorem?

The converse of the Pythagorean Theorem states that a triangle is a right triangle if the sum of the squares of two of its legs are equal to the square of the length of the longest side (hypotenuse).

The longest side in the triangle is 39 in. Therefore:

39² = 36² + 15²

1,521 = 1,521

Based on this, we can conclude that the triangle given is a right triangle.

let's notice something on this hyperbola, the fraction that is positive, is the fraction with the "y" variable, that simply means that the hyperbola is opening vertically, namely runs over the y-axis or it has a vertical traverse axis, which means, that, the foci will be a certain "c" distance from the center over the y-axis, well, with that mouthful, let's proceed.

AC = 17

BC = 15

We have to find tan A.

We know,

tan A = Opposite side / Adjacent side

In the given right angle triangle:
