M = 8 7 4
2 0 5
a) 2
b) 7
c) 5
d) 4

Answers

Answer 1
The correct answer is Option B) 7.

The POSITION of an element in a matrix is given by the row and column containing the element. This is usually denoted using double subscript notation, “aij” where first number is the row and j is the column containing the element aij.

In your given problem, “1” corresponds to the row, and “2” corresponds to the column. The element in the given matrix that is row 1, column 2 is the element, 7.

Therefore, the correct answer is B) 7.

I need help with this, please.
Red oak trees grow at a rate of about 2 feet per year. You buy and plant two red oak trees, one that is 6 feet tall and one that is 8 feet tall. The height h (in feet) of the shorter tree can be modeled by h=2t+6 where t is the time (in years) since you planted the tree. The height of the taller tree can be modeled by h=2t+8.

A. Graph both equations in the same coordinate plane.

B. Use the graphs to find the difference of the heights of the trees 5 years after you plant them. What is the difference after 10 years? What do you notice about the difference if the heights of the two trees?

Answers

Answer:

A: I think it's A because you need to graph both equations

Answer:

These are the screenshots of the work I did and more of the actual answer for graphing but basically,

The difference in heights of the trees after 5 years is 2 feet, after 10 years is 2 feet, and after any number of years is 2 feet since the lines are parallel.

5. Rewrite the quadratic funtion from standard form to vertex form.
Ax) = 2x2 + 8x + 70

Answers

Answer:

[tex]y = 2 {(x + 2)}^{2} + 62[/tex]

Step-by-step explanation:

vertex form is

[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]

our original equation

[tex]2 {x}^{2} + 8x + 70[/tex]

first we will find the x value using the formula

[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]

plug the value of x back into the original equation to solve for y

[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]

substitute this back into our vertex form and not forgetting the coefficient a = 2

[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

work out the value of x. 3x? x?

Answers

Answer:

x = 67.5

Step-by-step explanation:

Exterior angles always add up to 360 degrees. We have a defined right angle which takes 90 off of our 360, giving us 270 degrees. If we have x as an individual angle and also as x 3 times, then x is appearing 4 times. To find x, we divide our 270 degrees by 4 to get 67.5  . We can check this using a reversive property by multiplying 67.5 by 4 and then adding 90.

360 - 90 = 270

270 / 4 = 67.5

67.5 = x

p(x) = 2x² + 3x + 1

Answer :

R = 3

and (2x - 1) not factor of p(x) because, if (2x - 1) factor of p(x) remainder R when the polynomial p(x) divided by (2x - 1) is R = 0

1. Obtén la pendiente de las siguientes rectas, grafícalas y determina si las rectas L1 y L2, cuyas ecuaciones son 3x+4y-2=0 y 3x+4y+6=0, son paralelas o no.

Answers

Queremos obtener la pendiente de dos lineas dadas, y en base a eso, determinar si son paralelas o no.

Las pendientes son para ambas lineas igual a -3/4, como ambas lineas tienen la misma pendiente y diferente ordenada al origen, podemos concluir que son paralelas.

-----------------------------

Una línea en general se escribe como:

y = a*x + b

Donde a es la pendiente y b es la ordenada al origen.

En este problema se nos dan las líneas:

3*x + 4*y - 2 = 0

3*x + 4*y + 6 = 0

Comencemos por reescribir esas líneas en la forma más general, para hacer esto, debemos aislar y en ambas ecuaciones:

y = (-3/4)*x + 2/4

y = (-3/4) - (6/4)

Aqui podemos ver que ambas pendientes son iguales a -3/4

Al final de la respuesta puedes ver el gráfico de ambas líneas.

Como ambas líneas tienen la misma pendiente, pero distintas ordenadas al origen, podemos concluir que son paralelas.

Esto mismo se puede observar en el gráfico de abajo.

One way to build stairs is to attach triangular blocks to an angled support, as shown at the right. If the support makes a 32° angle with the floor, what must mâ 1 be so the step will be parallel to the floor? The sides of the angled support are parallel. *

Answers

Answer: m∠1 = 32°
Step-by-step explanation:
Since we have given that
The angled support making angle with the floor = 32°
So, we need to find the measure of angle 1 so that the steps are parallel to the floor.
As we know that "To make parallel to the floor , there should be alternate interior angle which must be equal."
So, m∠1 = 32° ( the angled support making angle with the floor)
Hence, m∠1 = 32°
