Step-by-step explanation:

Using the midpoint concept and the distance between two points, the correct statement is given by:

[tex]\sqrt{(0 - a)^2 + (2b - b)^2} = \sqrt{(2a - a)^2 + (0 - b)^2} = \sqrt{(a - 0)^2 + (b - 0)^2}[/tex]

The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.

Hence the coordinates of the midpoint of the hypotenuse are given as follows:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Hence the distance from the midpoint of the hypotenuse to any vertex is given by:

[tex]\sqrt{(0 - a)^2 + (2b - b)^2} = \sqrt{(2a - a)^2 + (0 - b)^2} = \sqrt{(a - 0)^2 + (b - 0)^2}[/tex]

The rate at which Riya is applying the mulch to the garden is 250000:1.

It should be noted that rate is simply used to show the relationship between two things. A rate in mathematics is the comparison of two related values expressed in different units. The numerator of the ratio expresses the corresponding rate of change in the dependent variable if the denominator of the ratio is written as a single unit of one of these quantities and it is assumed that this quantity may be modified systematically (i.e., is an independent variable).

Per unit of time is a frequent sort of rate, and examples include speed, heart rate, and flux. Exchange rates, literacy rates, and electric field ratios are examples of ratios with a non-time denominator (in volts per meter).

From the information, Riya is applying mulch to the garden and she applied at a rate of 250000cm³ for every m² of space.

Therefore, the rate at which Riya is applying the mulch to the garden is 250000:1.

Step-by-step explanation:

I guess, the equation is meant to be in slope-intercept form :

y = ax + b

"a" is the slope, "b" is the y intercept (the y value when x = 0).

in a situation like this, where we have the slope and one point of the line, we can start with the point-slope form

y - y1 = a(x - x1)

"a" is again the slope, and (x1, y1) is the given point.

and then we transform this over to the slope-intercept form.

so, in our case here

y - 2 = 5/6 × (x - 5) = 5x/6 - 25/6

let's simplify this by multiplying everything by 6 :

6y - 12 = 5x - 25

6y = 5x - 13

y = 5/6 x - 13/6

or

y = 1/6 × (5x - 13)

The sum of the three numbers 7531, 5252 and 6375 is 19158

The numbers are given as

7531, 5252, 6375

Express the numbers as a summation expression

So, we have

Sum = 7531 + 5252 + 6375

Evaluate the sum

So, we have

Sum = 19158

Hence, the sum of the three numbers 7531, 5252 and 6375 is 19158

Answer: h=1

Step-by-step explanation:

multiple 5h and -4 by 7

35h-28-1=14-8h

35h-29=14-8h

add 29 to both sides

35h=43-8h

43h=43

i think this is right...

The given equation is,

→ 7(5h - 4) - 1 = 14 - 8h

Now the required value of h will be,

→ 7(5h - 4) - 1 = 14 - 8h

→ 35h - 28 - 1 = 14 - 8h

→ 35h - 29 = 14 - 8h

→ 35h + 8h = 14 + 29

→ 43h = 43

→ h = 43/43

Two consecutive asymptotes are θ = - π / 20 and θ = 3π / 20 and the period is π / 5.

In this question we must look for two consecutive vertical asymptotes related to a trigonometric function. A function becomes undefined when its denominator is zero. Now we proceed to simplify the expression by trigonometric formulas:

y = 4 · csc (5θ - 3π / 4)

y = 4 / sin (5θ - 3π / 4)

y = 4 / (sin 5θ · cos 3π / 4 - cos 5θ · sin 3π / 4)

y = 4 / [(- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ]

The function is undefined for (- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ = 0:

(- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ = 0

(- √2 / 2) · sin 5θ = (√2 / 2) · cos 5θ

- sin 5θ = cos 5θ

tan 5θ = - 1

5θ = - π / 4 + i · π

θ =  - π / 20 + i · π / 5

θ = (π / 5) · (- 1 / 4 + i)

There are two consecutive asymptotes:

i = 0

θ = - π / 20

i = 1

θ = 3π / 20

And the period is ΔT = 3π / 20 - (- π / 20) = π / 5.

The amount of markup on a single rose is $2.74.

The markup formula is defined as the profit per unit cost of an item and is given as,

Markup = 100 * profit/cost

We multiply by 100 because we express it as a percentage, not as a fraction.

Now it is given that,

Cost Price of a dozen roses = $2.96

Number of roses = 12

Thus, Cost Price of 1 rose = 12.96/12 = $.108

Now it is also given that, the these dozen roses are sold at $48.48

So, Selling price of 1 rose = 48.48/12 = $4.04

Thus, Profit = Selling Price - Cost Price

⇒  Profit = $4.04 - $1.08

⇒  Profit = $2.96

Thus,Amount of Markup of single rose = Profit/Cost of 1 rose

⇒ Amount of Markup of single rose = 2.96/1.08

⇒ Amount of Markup of single rose = 2.74

Thus, the amount of markup on a single rose is $2.74.

It depends on what you mean "simplify". Chances are the goal here is to resolve any exponents that are improper fractions, meaning we don't want exponents larger than 1, like 4/3, for instance, but smaller than 1, like 2/3, is okay.

Now, by the distributive property of exponentiation,

[tex]\left(x^4 y\right)^{2/3} = \left(x^4\right)^{2/3} y^{2/3}[/tex]

Since [tex](x^a)^b = x^{ab}[/tex], we have

[tex]\left(x^4 y\right)^{2/3} = x^{4\cdot2/3} y^{2/3} = x^{8/3} y^{2/3}[/tex]

Convert the improper fraction to a mixed number.

[tex]\dfrac83 = 3 + \dfrac23[/tex]

Then we can write

[tex]x^{8/3} = x^{3 + 2/3} = x^3 x^{2/3}[/tex]

since [tex]x^{a+b}=x^ax^b[/tex].

Finally, we group together the factors with the same power.

[tex]\left(x^4 y\right)^{2/3} = x^3 x^{2/3} y^{2/3} = \boxed{x^3 (xy)^{2/3}}[/tex]

Answer:

Angle A is 20°

Step-by-step explanation:

The sum of the interior angles of a triangle is 180°.  

90 + 10x + x +13 = 180  Combine like terms

103 + 11x + 180  Subtract 103 from both sides

11x = 77  Divide both sides by 11

x = 7

Angle A is 13 + x.  X is 7, so 13 + 7 = 20

The inverse of function f( x ) = ( 2x - 3)² is [tex]y=\frac{\pm\sqrt{x} +3}{2}[/tex].

A function that can reverse into another function is known as an inverse function or anti-function. A function takes in values, applies specific operations to them, and produces an output. In order to find y when x is swapped with another variable, we must first determine the inverse function. On the other hand, the inverse function and the original function likewise have interchangeable domains and ranges.

We have the function,

f(x) = y = ( 2x - 3 )²

x = ( 2y - 3 )²

2y - 3 = ±√x

Adding 3 from each side.

2y - 3 + 3 = ±√x + 3

2y = ±√x + 3

Dividing each side of the equation by 2.

[tex]y=\frac{\pm\sqrt{x} +3}{2}[/tex]

Hence, the inverse of function f( x ) = ( 2x - 3 )² is [tex]y=\frac{\pm\sqrt{x} +3}{2}[/tex].

Answer:

Step-by-step explanation:

Hey there!

In order to find which description of the graph matches the problem, we must first create an equation or an inequality

So, we need to find how much more people the company needs to reach their goal to generate at least $7,300 in monthly revenue

We know that each person adds $300 to the already total of $5,500 per month

Now we can form the equation with this knowledge

[tex]300x + 5,500 \geq 7,300[/tex] where x is the number of people

Now we can simplify the equation

[tex]300x\geq 7500 - 5500\\ 300x\geq 2000\\x\geq 6.67[/tex]

Since we cannot have 6.67th of a person, we must round down because it means that we need more than 6 people

If we round up, it means that you need more 7 people in order to get $7,300 which isn't true

This means, you need more than 6 salespeople per month in order to meet the monthly quota of $7,300 in monthly revenue

Now that we know this, we can make a graph, or find the correct description of the graph

Since they need more than 6 people, the dot that sits on 6 in the number line will not be filled in, indicating that you need more than 6 salespeople

And since we need MORE, not LESS, the line will be pointing to the right

So, the correct answer would be D.

120% of original price=$307.32

1% of original price=$307.32/120
