Point A is the pre-image of a vertex of a square and is located at (-10, 8). The square is dilated with the center of dilation at the origin. Point A' is the image and us located at (-7, 6). What is the scale factor of the dilation?

Step-by-step explanation:

Subtracts those with same units but given that 40" is lower than 50", we need to borrow from 50' which can be read as 50 minutes.

40" is read as 40 seconds. Since 1 minute has 60 seconds, we have:

40" + 60" = 100" and

50' - 1' = 49'

These values will yield 60° 49' 100"

Now that the upper values are higher than the one below, we can now perform the operation:

60° - 30° = 30°

49' - 40' = 9'

100" - 50" = 50"

Step-by-step explanation:

Answer:

Step-by-step explanation:

1). Unit rate = slope of the graph at x =1

   Unit rate means value of y at x = 1

   From the graph of the given function,

   (1, 2) is the point which defines the unit rate.

2). Table (1),

   If the data shows the proportional relationship,

   [tex]\frac{y_1}{x_1}=\frac{y_2}{x_2}[/tex]

   [tex]\frac{2}{6}=\frac{1}{3}[/tex]

   [tex]\frac{1}{3}= \frac{1}{3}[/tex]

   Therefore, table (1) represents the proportional relationship.

   Table (2),

   If the data given in table is proportional,

   [tex]\frac{y_1}{x_1}=\frac{y_2}{x_2}[/tex]

   [tex]\frac{8}{5}=\frac{4}{2}[/tex]

   [tex]\frac{8}{5}=\frac{2}{1}[/tex]

   Which is not true.

   Therefore, table (2) doesn't show the proportional relationship.

Answer:

[tex]\dfrac{x^3-2x^2+4x-3}{x-2}[/tex]

Step-by-step explanation:

The given equation is :

[tex]x^2+\dfrac{4x-3}{x-2}[/tex]

We need to decompose this equation.

We have,

[tex]x^2+\dfrac{4x-3}{x-2}\\\\=\dfrac{x^2(x-2)+4x-3}{x-2}\\\\=\dfrac{x^3-2x^2+4x-3}{x-2}[/tex]

So, [tex]\dfrac{x^3-2x^2+4x-3}{x-2}[/tex] is the decomposed form of the given expression.

Answer:

Step-by-step explanation:

If a point is dilated by a scale factor 'k' centered at the origin,

Coordinates of the image point becomes as,

(x, y) → (kx, ky)

By this rule,

Coordinates of the vertices of the image triangle, when preimage is scaled by a factor of 5 about the origin will be,

T(-1, -2) → T'(-5, -10)

U(2, -2) → U'(10, -10)

V(-1, 1) → V'(-5, 5)

Answer:

4/8 is greater than 2/10

Step-by-step explanation:

4/8=.50

2/10=.20

Answer:

4/8 > 2/10

Step-by-step explanation:

because 4/8 also equals 1/2 and 2/10 equals 1/5 so 4/8 is bigger than 2/10

Answer:

If the price increase happens, your order would be $50.4.

Step-by-step explanation:

To be able to determine how much would the order be if the price increase happens, first you have to calculate 12% of the normal price per order:

$45*12%=$5.4

Then, you have to add $5.4 that is the amount of the increase plus the normal price per order:

$5.4+$45=$50.4

According to this, the answer is that if the price increase happens, your order would be $50.4.

Answer:

A is neither, B is direct, and C is inverse

Step-by-step explanation

In B, as x increases y also increases, in C as x increases y decreases, and in A it's neither because it's not one line (if you graphed it you would understand what I mean).  Though I have no idea what is constant of variations.

Answer:

47.5% of these led lights have lifetime between 7.9 and 8.9 hours.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 7.9 hours

Standard deviation = 0.5 hours

The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.

Lifetime between 7.9 and 8.9 hours:

7.9 hours is the mean.

8.9 = 7.9 + 2*0.5

So 8.9 hours is two standard deviations above the mean.

Of the 50% of the measures that are above the mean, 95% are between the mean of 7.9 and two standard deviations above the mean(8.9). So

0.5*0.95 = 0.475

47.5% of these led lights have lifetime between 7.9 and 8.9 hours.

Answer: 6,987,000 pounds fo CO₂ per kWh.

Step-by-step explanation: Quilowatt-hour (kWh) is a unit of energy that measures the amount of energy expended in 1 hour.

The AC uses 850 Watts, which in kW is 850,000 kW

If you leave the AC on for 6 hours, it will consume

850,000(6) = 5,100,000 kWh

Eletricity produces 1.37 pounds of CO₂ per kWh, then in 5,100,000 kWh:

1.37 [tex]\frac{pounds}{kWh}[/tex].(5,100,000kWh) = 6,987,000 pounds

If you open a window for 6 hours, you would keep 6,987,000 pounds of CO₂ for entering the atmosphere.

Answer:

4.1935483871km

Step-by-step explanation:

Distance to and back = 1.3 miles *2 = 2.6miles

To convert kilometres to miles, multiply by 0.62. Therefore, to convert from miles to kilometres, divide by 0.62.

2.6/0.62=4.1935483871km
