(C) classify each type of discontinuity

Answer:

We can use the sine law to find h. First, we determine the angle between the line of sight and h:

180 - 90 - 39 = 51 degrees

The sine law states that the ratio of one triangle's angle to the opposite side's length is the same as another angle to its opposite side's length, so we can solve for h as follows:

h/sin(39) = 500/sin(51)

h = 500*sin(39)/sin(51)

When we round to the nearest whole number, we get h = 405 ft.

What is the scale factor of this dilation? a:1/2 b:2/3 c:3/4 d:3/2

Answer: Option 4 - 1440

Step-by-step explanation:

2 Square Sides : Take 12 times 12 and times by two for both sides.

12 x 12 = 144     144 x 2 = 288

4 rectangular sides : The multiplication of 12 times 24

12 x 24 = 288    288 x 4 = 1152

Added All Together : 288 + 1152 = 1440

Answer:

[tex]8y = 20x[/tex]

Step-by-step explanation:

Given

[tex]y=\dfrac{5}{2}x[/tex]

Required

Determine equivalent expressions

A. 5y = 2x

[tex]y=\dfrac{5}{2}x[/tex]

Multiply through by 5

[tex]5 * y=\dfrac{5}{2}x * 5[/tex]

[tex]5y=\dfrac{25}{2}x[/tex]

This is not equivalent

B.  8y = 20x

[tex]y=\dfrac{5}{2}x[/tex]

Multiply both sides by 8

[tex]8 *y=\dfrac{5}{2}x * 8[/tex]

[tex]8y=\dfrac{5 * 8}{2}x[/tex]

[tex]8y=\dfrac{40}{2}x[/tex]

[tex]8y = 20x[/tex]

The other options are not clear.

However, another possible relationship is when

[tex]y=\dfrac{5}{2}x[/tex]is cross multiplied

This gives:

Answer:

Her pay for the week= $ 611.325

Step-by-step explanation:

Sallie is paid $ 11.40 per hour for regular hours.

The total regular hours worked during the week are

Monday + Tuesday + Wednesday + Thursday+ friday = 8 + 8+ 8+6+8= 38 hours

She works overtime during the week

Monday + Tuesday + Wednesday = 2+ 1/4+  1 1/2=  2+ 1/4 + 3/2

= 8 +1+ 6/4=15/4 = 3 3/4 hours

Over the weekend she works five hours .

So the total pay would be

$ 11.40( 38 ) + $ 11.40( 1.5) (  15/4) + $ 11.40 ( 2) ( 5)

= 433.2 + 64.125 + 114.0

= $ 611.325

Answer:

5.5 hours

Step-by-step explanation:

For every 1 hour, there is a 0.8 degrees Celsius drop in temperature.

Let "t" represent the total amount of temperature dropped.

Let "h" represent the number of hours

The given scenario can be represented with the equation below:

[tex] t = 0.8h [/tex]

To find the number of hours (h), it takes for the temperature to decrease by 4.4 degrees Celsius, plug in the value of t in the equation, and solve for h.

[tex] t = 0.8h [/tex]

[tex] 4.4 = 0.8h [/tex]

Divide both sides by 0.8

[tex] 5.5 = h [/tex]

It would take 5.5 hours for the temperature to decrease by 4.4 degrees Celsius.

Answer:

1. 8y/-3 = -24

2. 9x - 7 = 20

Answer:

10 hours

Step-by-step explanation:

First we need to find the rate Chad is driving. The rate is equal to distance/time, so we do 168/2, which is 84 mph. Then we have to find the time, which is distance/rate, so that would be 840/84, which is 10 hours.

Answer:

10 hours

Step-by-step explanation:

If Chad drove 168 miles in 2 hours than he drove 84 miles in one hour. If he drove 840 miles than you divide 840 by 84 and you get 10 hours. To check your work you can do 84*10= 840 miles 84=representing the miles per hour and 10=representing the amount of hours he drove.

Answer:

La inclinación de una recta esta definida como el ángulo entre el eje x positivo y la recta.

Primero, podemos escribir genéricamente una recta como:

y = p*x + s

donde p es la pendiente de la recta, y s es la ordenada al origen.

Sabemos que para una recta que pasa por los puntos (a, b) y (c, d) podemos escribir la pendiente como:

p = (d - b)/(c - a)

Y también sabemos que si θ es el ángulo de inclinación, entonces:

p = tan(θ)

Entonces en este caso sabemos que:

p = tan(71.56505118°) = -0.828

Entonces esta recta es:

y = -0.828*x + s

y sabemos que pasa por el punto (1, 2), entonces podemos remplazar esos valores en la ecuación para encontrar el valor de s.

2 = -0.828*1 + s

s = 2 + 0.828 = 2.828

La ecuación es:

y = -0.828*x + 2.828

Step-by-step explanation:

because when you include the steps, you can find out where you made a mistake (in case) and correct it easily.

Answer:

Step-by-step explanation:

x + 3y = 15   ×4

4x + 2y = 30   ×1

4x + 12y = 60

 -       -       -

4x + 2y = 30

      10y = 30

y = 30/10

y = 3

To solve for x, substitute y = 3 into any of the equations

x + 3(3) = 15

x + 9 = 15

x =  15 - 9

x = 6

(6,3)

This should be the answer but I don't see that in the options u listed, so I don't know what else it should be.

The required solution to the system of equations is (x, y) = (6, 3).  

Given the system of equations:

x + 3y = 15

4x + 2y = 30

Multiply Equation 1 by 2 to make the coefficients of y in both equations equal:

2(x + 3y) = 2(15)

2x + 6y = 30

Subtract Equation 2 from the modified Equation 1 to eliminate the variable x:

(2x + 6y) - (4x + 2y) = 30 - 30

-2x + 4y = 0

Divide the resulting equation by 2 to simplify it further:

-x + 2y = 0

Now, we have a new equation:

3) -x + 2y = 0

Add the new Equation 3 to the original Equation 1 to eliminate the variable x again:

(x + 3y) + (-x + 2y) = 15 + 0

5y = 15

Solve for y:

y = 15 / 5

y = 3

Now, substitute the value of y back into Equation 1 to find x:

x + 3(3) = 15

x + 9 = 15

x = 15 - 9

x = 6

Problem 1

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

Explanation:

The prisms are similar so they have the same shape, but different sizes.

The linear scale factor from small to large is:

large/small = 10/4 = 2.5

Meaning that we multiply each dimension of the smaller prism by 2.5 to get the corresponding side length of the larger prism

4*2.5 = 10

This linear scale factor is then cubed to get the volume scale factor

(2.5)^3 = 15.625

Which tells us:

larger volume = 15.625*(smaller volume)

smaller volume = (larger volume)/15.625

smaller volume = (1625)/15.625

smaller volume = 104 cubic inches

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

Problem 2

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

Explanation:

We will go back to the linear scale factor of 2.5

This time, we square it to get (2.5)^2 = 6.25

This is the surface area scale factor.

larger surface area = 6.25*(smaller surface area)

larger surface area = 6.25*(104)

larger surface area = 650 square inches
