The numbers are 6 and 7.

Let the values be x and x + 1.

Therefore, the equation will be:

4x + (x + 1)² = 73

4x + x² + 2x + 1 = 73

x² + 6x + 1 - 73 = 0

x² + 6x - 72 = 0

x² + 12x - 6x - 72

x(x + 12) - 6(x + 12)

Therefore, x - 6 = 0

x = 0 + 6 = 6

Therefore, the numbers are 6 and 7

Jane is traveling at 26.66 mph

Jill is traveling at 5.33 mph .

let the speed of jane and jill are

Jill = x mph

Jane = 5x mph

where mph= Miles per hour

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

we also write as -

Distance = rate x time

8x + 8(5x) = 256

 8x + 40 x = 256

48x = 256

x = 256/48

x = 5.33 mph

jill is traveling at 5.33 miles per hour. We can find jane speed by put the value of x

5 x = 5×5.33

5x = 26.66 mph

So Jane is traveling at 26.66 mph

      Jill is traveling at 5.33 mph

The value obtained from the given function f(z) = 10z²-9z+3 are-

For the given function;

f(z) = 10z²-9z+3.

The quotient is given as;

Quotient = f(4+h)-f(4)

Put the values (4 + h) and 4 at the place of z in the function.

f(4+h)-f(4) = 10(4 + h)² - 9(4 + h) + 3 -[10(4)² - 9(4) + 3)]

f(4+h)-f(4) = 10h² + 160 -9h + 80h + 3 - 160 + 36 - 3

Cancel the values;

f(4+h)-f(4) = 10h² + 80h - 9h

f(4+h)-f(4) = 10h² + 71h.

Thus, comparing the obtained equation by give form of (ah + b)

a = 10h and b = 71h.

The figure with these coordinates are R'(0, -4), S'(2, 0), T'(3, 0) and U' (4, -1) given below. Therefore, option A is the correct answer.

Given that, the translation is 3 units right and 4 units down.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions. Since it is just moving the shape from one place to other, there is no change in the shape.

The coordinates of the given figure are R(-3, 0), S(-1, 4), T(0, 4) and U(1, 3).

If the translation is 3 units right and 4 units down, then the coordinates become (x+3, y-4).

That is, R'(-3+3, 0-4)=(0, -4)

S'(-1+3, 4-4)=S'(2, 0)

T'(0+3, 4-4)=T'(3, 0)

U'(1+3, 3-4)=U' (4, -1)

So, the coordinates are R'(0, -4), S'(2, 0), T'(3, 0) and U' (4, -1)

The figure with these coordinates are R'(0, -4), S'(2, 0), T'(3, 0) and U' (4, -1) given below. Therefore, option A is the correct answer.

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

An experiment is The Implicit Association Tests (IAT). By taking measures, IAT assesses how strongly concepts are associated with one another. According to Carpenter et al.

Add 3 to all sides of the inequality

So, we have

3x + 5 > 2x > x - 8

Split the inequality

So, we have

3x + 5 > 2x  and 2x > x - 8

Evaluate the like terms

x + 5 > 0  and x > - 8

The solution of the given differential equation is;

-1/(b/a + 4) = -㏑|a| - 1/5.

The given differential equation is-

(b² + 7ab + 16a²)da + a²db = 0

Take da common from both;

b² + 7ab + 16a² + a²db/da = 0

The curve passes through the point (a = 1, b = 1).

As, the given differential eq is the homogeneous eq; we can use it as;

Put, b = va

Differentiate above applying product rule.

db/da = (dv/da)a + v

Substitute the value in the main equation;

(va)² + 7a(va) + 16a² + a²( (dv/da)a + v ) = 0

Dividing whole equation by a².

v² + 7v + 16 + (dv/da)a + v  = 0

Further simplifying;

(dv/da)a = -(v² + 8v + 16)

(dv/da)a = -(v + 4)²

Bring similar variable together;

dv/(v + 4)² = -da/a

Integrating the equation;

-1/(v + 4)  = -㏑|a| + C    ; c is the integration constant.

Substitute again the values of v;

-1/(b/a + 4)  = -㏑|a| + C   ........equation 1

Now use the given points; a = 1; b = 1.

-1/(1/1 + 4)  = -㏑|1| + C      [㏑|1| = 0]

-1/5 = C

Put the value of C in equation 1.

The clothes dryer uses the maximum energy at 1.018 × 10⁶ kilowatt-hour

Kilowatt-hours are primarily used to sell electrical energy to customers. A device's power consumption in kilowatts, operating time in hours, and price per kilowatt-hour are multiplied to get the cost of running it. Utility companies' charges for power may vary based on the customer's consumption patterns over time. Prices vary widely depending on the location. Prices in the US can differ by a factor of three between states.

A composite energy unit called a kilowatt-hour is defined as one kW sustained for (and multiplied by) one hour. It is equivalent to 3600 kilojoules, or 3.6 MJ, when expressed in the joule (symbol J), the SI's base unit of energy.

So from the given conditions the television uses the least amount of energy per day at 300 kilowatt-hour.

The amount of energy per year:

Television  = 300 × 365 = 1.095 × 10⁵ kilowatt-hour

Dryer = 2790 × 365 = 1.018 × 10⁶ kilowatt-hour

Refrigerator = 225 × 365 = 8.213 × 10⁴ kilowatt-hour
