Greetings from Brasil...

The expression that allows you to calculate the distance between two points is:

Bringing to our problem:

d(A; B) = √[(9 - 0)² + (14 - 2)²]

d(A; B) = √[9² + 12²]

d(A; B) = √[81 + 144]

d(A; B) = √[225]

Answer:

Option (4)

Step-by-step explanation:

Coplanar points-

If two or more points are in the same plane, points are called to be coplanar points. Three points in space are always coplanar.

Collinear points-

If two or more points are on a straight line, points are collinear.

Two points are always collinear.

From the diagram attached,

Points R,T,Q and S are neither coplanar nor collinear.

Therefore, Option (4) will be the answer.

Answer:

Step-by-step explanation:

Given RS = 6y+2, ST=3y +7, and RT=13y-23, the vector formula is true for the equations given; RS+ST = RT

Om substuting the expression into the formula;

6y+2+3y +7 = 13y - 23

collect the like terms

6y+3y-13y+2+7+23 = 0

-4y+32 = 0

Subtract 32 from both sides

-4y+32-32 = 0-32

-4y = -32

y = -32/-4

y = 8

Since ST = 3y+7. we will substitute y = 8 into the exprrssion to get ST

ST = 3(8)+7

ST = 24+7

ST = 31

Similarly,

RT = 13y-23

RT = 13(8)-23

RT = 104-23

RT = 81

Hence y = 8, ST = 31 and RT = 81

Answer:

Step-by-step explanation:

Answer:

Height = 16 in

Step-by-step explanation:

C = Hypotenuse = the longer side of a triangle

A = Height

B = Base

=> a^2 + b^2 = c^2

=> a^2 + 30^2 = 34^2

=> a^2 + 900 = 1156

=> a^2 + 900 - 900 = 1156 - 900

=> a^2 = 256

=> Square root of a^2 = Square root of 256

=> a = 16

So, The Height of the triangle = 16 in.

Answer:

[tex]\angle A = 40^o[/tex]

Step-by-step explanation:

Notice that angle A is identified with the algebraic expression "7 + 3 x", while the other acute angle is identified with the expression "5 x - 5"

We know that the third angle is a right angle (90 degrees),

and also that the sum of the internal angles in a triangle must give 180 degrees, so we have:

[tex]\angle A + \angle B+ 90^o = 180^o\\(7+3\,x)+(5\,x-5)=180^o-90^o\\7+3\,x+5\,x-5=90^o\\8\,x+2 = 90^o\\8\,x=88^o\\x=11^o[/tex]

Now that we know x, we can give the answer for what angle A is:

[tex]\angle A= 7^o+3\,x\\\angle A =7^o+3\,(11^o)\\\angle A = 7^o+33^o\\\angle A = 40^o[/tex]

Answer:

12 (D)

Step-by-step explanation:

The first one is 2:1.2 so i did x10 on it to get 20:12.

The missing value in the table is 12 miles.

Option D is the correct answer.

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 km = 1000 m

1 minute = 60 seconds

We have,

Kilometer    Miles

2                     1.2

7                     4.2

20                  12

30                  18

We see that,

2 km = 1.2 miles

Multiply 7/2 on both sides.

7  km = 7/2 x 1.2 miles

7 km = 4.2 miles

Multiply 20/ 7 on both sides.

20 km = 12 miles

Thus,

20 km is 12 miles.

Answer:

40 + 2x ≥ 75

Step-by-step explanation:

X equals 18 or above. This means that in order to meet her goal of $75 dollars, Charlotte needs to schedule at least 18 appointments.

Answer:

A=

2x+40=75

B=

Charlotte would have to schedule 18 appointments.

First you have to subtract 40 from 75 which equals 35

Second you divide 35 by 2 which equals 17.5

Since Charlotte can't schedule 17 1/2 appointments so you round up to 18

Step-by-step explanation:

Answer:

1) [tex](f+g)(x)=2x^2+3x-6[/tex]

2) [tex](f-g)(x)=2x^2+x[/tex]

3) [tex](f \cdot g)(x)=2x^3-4x^2-9x+9[/tex]

Step-by-step explanation:

So we have the two functions:

[tex]f(x)=2x^2+2x-3\text{ and } g(x)=x-3[/tex]

And we want to find (f+g)(x), (f-g)(x), and (f*g)(x).

1)

(f+g)(x) is the same to f(x)+g(x). Substitute:

[tex](f+g)(x)=f(x)+g(x)\\=(2x^2+2x-3)+(x-3)[/tex]

Combine like terms:

[tex]=(2x^2)+(2x+x)+(-3-3)[/tex]

Add:

[tex]=2x^2+3x-6[/tex]

So:

[tex](f+g)(x)=2x^2+3x-6[/tex]

2)

(f-g)(x) is the same to f(x)-g(x). So:

[tex](f-g)(x)=f(x)-g(x)\\=(2x^2+2x-3)-(x-3)[/tex]

Distribute:

[tex]=(2x^2+2x-3)+(-x+3)[/tex]

Combine like terms:

[tex]=(2x^2)+(2x-x)+(-3+3)[/tex]

Simplify:

[tex]=2x^2+x[/tex]

So:

[tex](f-g)(x)=2x^2+x[/tex]

3)

(f*g)(x) is the same to f(x)*g(x). Thus:

[tex](f\cdot g)(x)=f(x)\cdot g(x)\\=(2x^2+2x-3)(x-3)[/tex]

Distribute:

[tex]=(2x^2+2x-3)(x)+(2x^2+2x-3)(-3)[/tex]

Distribute:

[tex]=(2x^3+2x^2-3x)+(-6x^2-6x+9)[/tex]

Combine like terms:

[tex]=(2x^3)+(2x^2-6x^2)+(-3x-6x)+(9)[/tex]

Simplify:

[tex]=2x^3-4x^2-9x+9[/tex]

So:

[tex](f \cdot g)(x)=2x^3-4x^2-9x+9[/tex]

Answer:

(10, - 6)

Step-by-step explanation:

P = (7, - 5)

T(P) = [x +3, y + (-1)]

T(P) = [7 +3, - 5+ (-1)]

T(P) = [7 +3, - 5 -1]

T(P) = (10, - 6)

The translated coordinates of the points  (7,-5) will be  (10, 2).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

The image point of (7,-5)after a translation right 3 units and down 1 unit will be,

= [(7+3), (3-1)].

= (10, 2).

Step-by-step explanation:

find full equation by plugging in P

y = mx + b

y = 6x + b

-5 = 6(2) + b

b = -17

y = 6x - 17

find y-value by plugging in x-value to equation

y = 6(3.5) - 17
