Answer:

ABCD is a rhombus => AC is perpendicular with BD

=> AC = 2(2n + 5) = 30

<=> 2n + 5 = 15

=> n = 5

with n = 5 => AC/2 = 15

BD/2 = 4.5 - 3 = 17

BC² = (AC² + BD²)/4 = 514/4 = 128.5

=> BC = 11.34

Answer:

Step-by-step explanation:

The question is what does 2n + 5 represent? Is it 1/2 the line or all of AC. There seems to be a run on ambiguous questions. I'm going to assume that 2n + 5 is AC -- all of it. And 4n-3 is all of BD.

AC = 30

2n + 5 = 30      Subtract 5 from both sides.

2n = 30 - 5

2n = 25            Divide by 2

n = 25/2

n = 13.5

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

BD = 4n - 3

BD = 4*13.5 - 3

BD = 54 - 3

BD = 51

red bike is traveling south, toward Lawrence, at constant speed of 24km/h and a blue bike is also traveling east, away from Lawrence, at a constant speed of 12 km/h. when t=0, the red bike is 10 km north and the blue bike is 6 km east of Lawrence a. express the distance of the red bike from Lawrence, R, as a function of time in hours, t. b. express the distance of the blue bike from Lawrence, B, as a function of time in hours, t.

Answers

Answer:

a.[tex]R=10-24t[/tex]

b.[tex]B=6+6t[/tex]

Step-by-step explanation:

We are given that

Speed of red bike, v=24 km/h

Speed of blue bike, v'=12km/h

Distance of red bike when t=0

=10 km north

Distance of blue bike when t=0

=6km east

a. We have to find the expression of distance of red bike from Lawrence.

[tex]Distance=speed\times time[/tex]

Let t be the time taken by red bike

Distance of red bike from Lawrence is given by

[tex]R=10-24\times t[/tex]

[tex]R=10-24t[/tex]

b.

Distance of the blue bike from Lawrence

[tex]B=6+6\times t[/tex]

[tex]B=6+6t[/tex]

The functions f(x) and g(x) are shown on the graph.
f(x) = x²
What is g(x)?

Answers

G(x) is 3(2) because the slope is decreased

The required function g(x) is given as g(x) = 3x².

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,

In the graph, we have a graph of two functions,
f(x) = x² and there is a point (2, 12) located on the curve of function g(x)

we have to determine the function g(x).

Now,
Now, as g(x) is scaled function of f(x)

g(x) = k f(x) - - - - (1)

At x = 2
g(2) = 12
f(2) = 4

Put x = 2 in question 1,
g(2) = k(f(2))
12=k*4
k = 3

Substitute k in equation 1 we get,
g(x) = 3x²

Thus, the required function g(x) is given as g(x) = 3x².

La extencion territorial de mexico es de 1960198 km2 , mientras que mocano tiene una superficie de 202.7 ha ¿cuantas veces cabe la superficie de mocano en la de mexico

Answers

Answer:

La superficie de mocano cabe 967.044 veces en la superficie de Mexico.  

Step-by-step explanation:

Primero debemos convertir la unidad de la superficie (S) de mocano (m):

[tex] S_{m} = 202.7 ha*\frac{10000 m^{2}}{1 ha} = 2.027 \cdot 10^{6} m^{2} [/tex]

Ahora podemos calcular cuantas veces cabe la superficie de mocano en la de Mexico (M):

[tex] \frac{S_{M}}{S_{m}} = \frac{1.960198 \cdot 10^{9} m^{2}}{2.027 \cdot 10^{6} m^{2}} = 967.044 [/tex]                                

Si multiplicamos la superficie de mocano por 967.044 nos da la superficie de Mexico:

[tex] 967.044*2.027\cdot 10^{6} m^{2} = 1960198 m^{2} [/tex]

Por lo tanto, la superficie de mocano cabe 967.044 veces en la superficie de Mexico.

Which is the graph of y= -x-3?

Answers

Answer:

Graph a

Step-by-step explanation:

Answer:

the answer is A

Step-by-step explanation:

to start, I would use the slope intercept, in this case -3 which lets you know the slope meets the y axis at (0,-3) since you have that point, you count with the slope.

now slope is rise over run, therefore, it would be y over x and since the y in this case is 3, you'd go up three from your point. since x is 4, you'd go right four units from where you are. since A is the only graph that follows that, A would be correct.

Solve for y (-14y=-42)

Divide both sides by −14.

Y= -42/-14

Two negatives make a positive.

How can you use the DISTRIBUTIVE PROPERTY solve the equation: 3(x-4) = 24 ? *

Answers

By using the Distributive Property, you would multiply 3 into the parenthesis (3 · x and 3 · -4)

3(x - 4) = 24

3x - 12 = 24

Then, you would solve like any normal one-step equation.

3x - 12 = 24

     +12   +12

__  =  __

x = 12, which is your final solution.

If you need any further explanations, please ask me :)

Answer:

3(x - 4) = 24 This is the normal equation.

3x - 12 = 24 Next, use the distributive property and multiply everything in the parentheses by the number on the right of the parentheses, which in this case is 3. 3 times x is 3x, and remember to use any symbols to the left of the numbers and use as if it was a negative. 3 times -4 -12. Get rid of the parentheses and replace with the new numbers, which are 3x and -12.

3x = 36  I think you are solving for X so that's what i'm doing.

x = 12
