Answer:

g(1)=5

Step-by-step explanation:

[tex]g(x)=2x^2-3x\\We\ find\ g(-1)\ by\ just\ substituting\ x\ with\ -1\ on\ the\ RHS.\\g(-1)=2(-1)^2-3*-1\\g(-1)=2*1+3\\g(-1)=2+3\\g(-1)=5[/tex]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

[tex]y=3x+7[/tex]

As we know that  the slope-intercept of the line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

so comparing the equation [tex]y=3x+7[/tex] with the slope-intercept of the line equation, we conclude that

[tex]y = 3x+7[/tex]

[tex]m = 3[/tex]

So, the slope of the line is [tex]m = 3[/tex]

As the function is

[tex]y = 3x+7[/tex]

Now, if we double the slope,

The slope will become: 2m = 2(3) = 6

Therefore, the function of the graph after doubling the slope will become:

[tex]y = 6x+7[/tex]

Answer:

coordinates of D are ( -8, 5)

Step-by-step explanation:

- the formula of the coordinates of the midpoint is (x1+x2)/2  & (y1+y2)/2

- first we find midpoint C by using coordinates of points A and B

C => (4 - 12)/2 & (8 + 4)/2

calculate, coordinates of C are ( -4, 6 )

- now find midpoint D by using the coordinates of B and C

D => ( -12 - 4 )/2 & (4 +6)/2

calculate and the coordinates of D are ( -8, 5 )

Answer:

Step-by-step explanation:

Answer: The GCF of 60, 70, and 80 is 10.

Step-by-step explanation: If you think about it, the GCF is definitaly going to be 10. That is because you can multiply 10 to get 60, 70, and 80. There is no other number higher than 10 that can be multiplied by something to get all of these values.

Step-by-step explanation:9

Answer:

Choice D

Step-by-step explanation:

First we should find the slope of the equation, so since it's perpendicular to the other equation that means it's the opposite and the reciprocal of that slope. So the slope is [tex]\frac{9}{4}[/tex].

Now we have to find the y-intercept. We already know the x-intercept, so we could use that to find the y-intercept. For that we need to know the slope and one ordered pair, which is (36,0). Then we plug into this formula  [tex]y=mx+b[/tex].

[tex]y=mx+b\\0=\frac{9}{4}(36)+b\\0=81+b\\b=-81[/tex]

So now that we found the y-intercept we just have to put it all together....

[tex]y=\frac{9}{4}x-81[/tex]

Answer:

m∠8 = 30°

Step-by-step explanation:

Since line AB is parallel to line CD, and m∠4 = 30°, therefore:

m∠4 and m∠8 are corresponding angles.corewslinding angles are congruent.

Therefore, this means that their measure would be equal to each other, since they are congruent.

Thus:

m∠8 = 30°

Answer:

La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.

Step-by-step explanation:

Asumamos que la transferencia de calor es enteramente por conducción, en estado estable y unidimensional´y que la ventana es representada por una placa plana. Bajo estas consideraciones, la ecuación de conducción es la siguiente:

[tex]\dot Q = \frac{k\cdot w\cdot h}{l}\cdot (T_{i}-T_{o})[/tex] (1)

Donde:

[tex]\dot Q[/tex] - Tasa de transferencia de calor, medida en watts.

[tex]k[/tex] - Conductividad térmica, medida en watts por metro-grado Celsius.

[tex]w[/tex] - Ancho de la ventana de vidrio, medido en metros.

[tex]h[/tex] - Altura de la ventana de vidrio, medida en metros.

[tex]l[/tex] - Espesor de la ventana de vidrio, medida en metros.

[tex]T_{i}[/tex] - Temperatura interior del vidrio, medida en grados Celsius.

[tex]T_{o}[/tex] - Temperatura exterior del vidrio, medida en grados Celsius.

Si conocemos que [tex]k = 0.8\,\frac{W}{m\cdot ^{\circ}C}[/tex], [tex]w = 2.5\,m[/tex], [tex]h = 1.5\,m[/tex], [tex]l = 2.8\times 10^{-3}\,m[/tex], [tex]T_{o} = 16\,^{\circ}C[/tex] y [tex]T_{i} = 20\,^{\circ}C[/tex], entonces la tasa de transferencia de calor es:

[tex]\dot Q = \left[\frac{\left(0.8\,\frac{W}{m\cdot ^{\circ}C} \right)\cdot (2.5\,m)\cdot (1.5\,m)}{2.8\times 10^{-3}\,m} \right]\cdot (20\,^{\circ}C-16\,^{\circ}C)[/tex]

[tex]\dot Q = 4285.714\,W[/tex]

La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.

Answer:

P = dependant; t = independant

Step-by-step explanation:

The t value can be changed, making it the indepentant. The value of P changes as the value of t is changed, therefore making it dependant on t, making it the dependant value.

Answer:

250

Step-by-step explanation:

you have to use the fact that the big triangle and the small triangle are similar and write the proportions

[tex]\frac{125}{10} =\frac{AB}{10}[/tex]  we took half of the side because of ΔABD and ΔBD..

AB= (125*10)/10=125

is AB =125 then AC is duble AC= 2*125=250

Answer:

Creo que es b

Step-by-step explanation:

The linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

Checking all the options to see if (3,6) lies on them:

Usually points are of the form (x,y). Thus, we have: (x,y) = (3,6) means x = 3, and y = 6.

Putting these values in the equation, we get:

[tex]y = 3x + 6\\6 = 3(3) + 6\\6 = 9 + 6\\6 = 15[/tex]

This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.

Putting x = 3, y = 6 in this equation, we get:

[tex]y = 6x - 3\\6 = 6(3) - 3\\6 = 18 - 3 \\6 = 12[/tex]

This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.

Putting x = 3, y = 6 in this equation, we get:

[tex]y = 2x\\6 = 3(2)\\6 = 6[/tex]

This is correct. Thus, the point (3,6) satisfy this equation, and therefore, lies on its graph.

Thus, the linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]
