The digit 4 in which number represents a value if 0.04

After using Pythagorean theorem the rectangular floor is 4m long.

What is Pythagorean theorem ?

 A right angled triangle's missing length can be discovered using Pythagoras' Theorem.

The triangle has three sides: the adjacent, which doesn't touch the hypotenuse, the opposite, which is always the longest, and the hypotenuse (which is between the opposite and the hypotenuse).

Here in the given rectangular floor,

Width = 3m and Altitude which is hypotenuse = 5 m.

Now using Pythagorean theorem,

=> \(length^2+width^2=hypotenuse^2\)

=> \(length^2+3^2=5^2\)

=> \(length^2=5^2-3^2\)

=> \(length^2=25-9=16=4^2\)

=> length = 4m

Hence the rectangular storage unit is 4m long.

Answer:

I believe it's A) "In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality."

Step-by-step explanation:

I say this because that's essentially the first step when solving both an equation and inequality.

(In case you were wondering, the next step would be to divide -3 on both sides, in order to get x by its self.)

12:1 is the scale factor

3.5 ÷ 3.5 = 1 and 142 ÷ 3.5 =123.5 so 42:123.5 ratio simplified is 12:1

Looking at the question, to find the scale factor we are going to divide 42 by 3.5 which is 12. To check our work we will do 1 times 3.5 which is 42.

Why is it not 147:1? Well, scale factoring means that in two similar geometric figures, the scale factor is the ratio of their corresponding sides, dividing the two corresponding lengths of the sides will gives the ratio

The vertex of the given equation is (0,12) and (1, -10). The value of y-intercept will be -12.

Given equation :

y=(x−2)2−8

y = 2x - 4 - 8

= 2x - 12

The final equation is y = 2x - 12.

Compare this equation with slope and y-intercept formula :

y = mx+c

So that c = -12

The value of y-intercept according to the solution is -12.

To find the vertex. Let's assume x=0; Substitute in the equation

y = 2(0) -12

y = -12

The first vertex will be (0, -12)

If x = 1; y = 2(1) -12

y = -10

Then the second vertex will be (1, -10).

Hence, the vertex of the given equation is (0,12) and (1, -10). The value of y-intercept will be -12.

Answer:

To increase the quantity of fruit baskets sold by 20%, we would need to charge $48 per basket.

Step-by-step explanation:

The price elasticity of demand measures the responsiveness of the quantity demanded of a good to a change in its price. In this case, a price elasticity of -2.0 means that a 1% increase in the price of the fruit basket will result in a 2% decrease in the quantity of fruit baskets demanded.

Using the midpoint formula to calculate the new price, we take the average of the initial price and the new price to get the midpoint. Then, we calculate the percentage change in both quantity demanded and price relative to this midpoint.

Setting the percentage change in quantity demanded equal to 20%, we can solve for the new price that would be required to achieve this increase in quantity demanded. The solution is $48, which represents a 20% increase from the original price of $40.

To increase the quantity of fruit baskets sold by 20%, we need to lower the price. The price elasticity of demand tells us how much we need to lower the price to achieve this increase in quantity. In this case, the price elasticity of demand is -2.0, which means that for every 1% increase in price, there will be a 2% decrease in quantity demanded, and vice versa.

Using the midpoint formula, we can calculate that the new price we should charge to achieve a 20% increase in quantity is $48. This means that we need to lower the original price of $40 by 20%, or $8, to arrive at the new price of $48.

Price elasticity of demand = percentage change in quantity demanded / percentage change in price

-2.0 = 20% / (P - $40) / (($40 + P) / 2)

where P is the new price we want to find.

Simplifying the equation:

-2.0 = 20% / (P - $40) / (($40 + P) / 2)

-2.0 = 20% / ((P - $40) / (($40 + P) / 2))

-2.0 = 10 / ((P - $40) / (($40 + P) / 2))

-2.0 = (2 * (($40 + P) / 2)) / (P - $40)

-2.0 = ($40 + P) / (P - $40)

-2.0(P - $40) = $40 + P

-2.0P + $80 = $40 + P

3.0P = $40 + $80

3.0P = $120

P = $40

Noted that Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2    

Given that

Hypotenuse, AC = 15 cm  and shorter leg, AB = 5.2 cm.

We are to find the length of the other leg, BC.

From Pythagoras' theorem, we have

\(|AC|^2 = |AB|^2 + |BC|^2 \\\\|BC|^2 = |15 |^2 - |5.2 |^2 \\\\|BC|^2 = 225 - 27.04 \\\\|BC|^2 = 197.96\\\\\)cm.

Answer:

x = 9, NM = 41

Step-by-step explanation:

Since KL = ML  then the triangle is isosceles and LN is a perpendicular bisector, thus

NM = NK , substitute values

7x - 22 = 3x + 14 ( subtract 3x from both sides )

4x - 22 = 14 ( add 22 to both sides )

4x = 36 ( divide both sides by 4 )

x = 9

Thus

NM = 7x - 22 = 7(9) - 22 = 63 - 22 = 41

Answer:

g^-1(x)=x/2+3/2

Step-by-step explanation:

Answer

Given the 2 equations

x = y + 4 → (1)

2x - 3y = - 2 → (2)

Substitute x = y + 4 into (2)

2(y + 4) - 3y = - 2 ← distribute and simplify left side

2y + 8 - 3y = - 2

- y + 8 = - 2 ( subtract 8 from both sides )

- y = - 10 ( multiply both sides by - 1 )

y = 10

Substitute y = 10 into (1) for corresponding value of x

x = 10 + 4 = 14

Answer: The correct interpretations about the graph of r(t) are B, D, and E.

Interpretation B is correct because the graph shows that the average mortgage rate fell to a relative minimum between 2002 and 2003.

Interpretation D is correct because the graph shows that the average mortgage rate was highest between 2006 and 2007, based on the absolute maximum.

Interpretation E is correct because an appropriate domain for this function would be 0≤t≤10, as t represents time and the graph shows data for the period between 2002 and 2010.

Interpretation A is not correct because the graph does not show that the average mortgage rate increased continuously between 2003 and 2005.

Interpretation C is not correct because the y-intercept does not represent the average mortgage rate in 2010. The y-intercept represents the value of the function when t = 0, which does not correspond to any time in the given data.

The answer of the given question based on the scatterplot for determining  when she will reach 10,000 songs the answer is Maria will reach 10,000 songs in approximately 13.33 months, or about 14 months.

Slope is  measure of  steepness or incline of  line. In geometry and mathematics, slope is defined as  ratio of the change in  y-coordinates to  change in  x-coordinates between two distinct points on  line. This is often represented by  letter "m".

To determine when Maria will reach 10,000 songs, we need to find the point on the line of best fit where the y-value is 10,000.

From the scatterplot, we can estimate that the line of best fit intersects the y-axis at approximately 2000. This means that the initial number of songs downloaded was 2000.

Next, we need to find the slope of the line of best fit. Let's choose the points (5, 6500) and (10, 9500).

The slope of the line passing through these two points is:

slope = (y2 - y1)/(x2 - x1) = (9500 - 6500)/(10 - 5) = 600 songs per month

This means that Maria is downloading 600 songs per month on average.

Finally, we can use the slope-intercept form of a line to find the x-value when the y-value is 10,000:

y = mx + b

10,000 = 600x + 2000

8000 = 600x

x = 13.33

Therefore, Maria will reach 10,000 songs in approximately 13.33 months, or about 14 months.

Answer:

30

Step-by-step explanation:

The absolute maximum value is 0 and it occurs at x = 0 and x = 8, while the absolute minimum value is also 0 and it occurs at the same points.

To find the absolute maxima and minima of the function y = 4√(x - x), where 0 ≤ x ≤ 8, we need to evaluate the function at its critical points and endpoints within the given interval.

First, let's find the critical points by taking the derivative of the function y with respect to x and setting it equal to zero:

y = 4√(x - x)

\(dy/dx = (4/2\sqrt{(x - x)} ) \times (1) = 2/\sqrt{(x - x) }\)

To find the critical points, we set dy/dx = 0:

2/√(x - x) = 0

The denominator cannot be zero, so there are no critical points within the given interval (0 ≤ x ≤ 8).

Next, we evaluate the function at the endpoints of the interval:

For x = 0:

y = 4√(0 - 0) = 4√0 = 0

For x = 8:

y = 4√(8 - 8) = 4√0 = 0

Hence, the function has minimum values of 0 at both endpoints of the interval.

Therefore, the absolute maximum value is 0 and it occurs at x = 0 and x = 8, while the absolute minimum value is also 0 and it occurs at the same points.
