Step-by-step explanatio

Answer:

the correct option is C.

Step-by-step explanation:

The x-intercept of both functions g(x) and f(x) occur at point (1, 0).

Now, we need to find where g(x) > f(x) and f(x) > g(x)

We know that the greater the base of a logaritmic function is, the faster it will grow/decay.

For that reason, we can say that g(x) > f(x)  on (1, +inf).

Now, when x<1 then y<0. So on the interval (0, 1) the function g(x) will decay much faster than the function f(x), so we can say that f(x) > g(x) on (0, 1). So the correct option is C.

Check the graph, to verify all this.

x = 10 and y = 46

Step-by-step explanation:

From the figure we can see a trapezium.

To find the value of x

We can write,

2x - 13 = x - 3

2x - x = 13 - 3

x = 10

To find the value of y

from the figure we can write,

3y - 4 + y = 180

4y = 180 + 4

4y = 184

y = 184/4 = 46

Therefore the correct answer is option B

x = 10 and y = 46

$1313.70 is the answer after a 51% markup

Final answer:

The selling price of a dining room set with a 51% markup on the selling price, and an actual cost of $870, is calculated to be $1775.51.

Explanation:

To determine the selling price of a dining room set with a 51% markup on the selling price based on the actual cost of $870, we first need to recognize the markup is on the selling price and not on the cost. Let the selling price be represented by the variable S. The markup can be represented by S multiplied by 51% (or 0.51), so we have:

Actual Cost + Markup = Selling Price

$870 + (0.51 × S) = S

To solve for S, we need to isolate it on one side of the equation:

$870 = S - (0.51 × S)

$870 = S(1 - 0.51)

$870 = S(0.49)

Now we divide both sides by 0.49 to solve for S:

S = $870 / 0.49

S = $1775.51

Therefore, the selling price of the dining room set at Macy's is $1775.51.

Answer:

X= O.8 or 10 over 12.5

Step-by-step explanation: Hope this helps darling

Answer:

3,172

Step-by-step explanation:

The "Money saved that week" is an arithmetic progression, where the next term is found by adding a constant value to the previous term. In this case, the variation is 2.

So that could be modeled with this equation: [tex]a_{n} = a_{1} + (n-1)V[/tex]

Where a1 is the first term of the series, in our case: 10, and the V is the variation each week, in our case: 2.

To be able to calculate the overall sum and answer the question, we first need to calculate the amount she will save on the last week (n=52).

[tex]a_{52} = 10 + (52-1) * 2 = 10 + 102 = 112[/tex]

Now that we know she'll save $112 on the 52nd week, let's calculate the total, using this formula:

[tex]S_{n} = \frac{(a_{1} + a_{n}) * n}{2}[/tex]

We know n (52), a1 (10) and an (112), so...

[tex]S_{52} = \frac{(10 + 112) * 52}{2} = \frac{122 * 52}{2} = 3,172[/tex]

At the end of the year, she will have saved $3,172

Step-by-step explanation:

"Is" means equals.  "Less than" means subtracted from.

28 = k - 12

Add 12 to both sides to solve for k:

k = 40

The equation representing the statement '28 is 12 less than K' is 28 = K - 12. By adding 12 to both sides of the equation and simplifying, we find that K = 40.

To represent the statement '28 is 12 less than K' with an equation, you write: 28 = K - 12. To solve for K, you would add 12 to both sides of the equation.

Step 1: Add 12 to each side of the equation to isolate K.

28 + 12 = K - 12 + 12

Step 2: Simplify each side.

40 = K

Therefore, the value of K is 40.

Answer:

0.953081279

Step-by-step explanation:

we have been given the following data set;

x; 4, 5, 8, 9, 13

y; 2, 9, 10, 12, 23

We are required to determine the r value of the data set.The r-value is the correlation coefficient that is used to measure the degree of association between two variables. It gives us information on the strength and direction of the association.

We can easily compute r in Ms. Excel;

We first enter the data into any two adjacent columns of an excel workbook.

Then we proceed to type;

=CORREL

into any blank cell. This is an in-built function that computes the correlation coefficient. Ms. Excel returns a value of  0.953081279

as the r value

Answer:

The value of r is 0.953.

Step-by-step explanation:

The correlation coefficient i.e. r is calculated by the formula,

[tex]r=\dfrac{n\sum{xy}-(\sum x)(\sum y)}{\sqrt{(n\sum x^2-(\sum x)^2)(n\sum y^2-(\sum y)^2)}}[/tex]

where n=5 is the sample size.

We create a table of required values,

         x        y          x²          y²           xy

        4        2         16           4             8  

        5        9         25         81            45

        8        10        64         100         80

        9        12         81         144         108

        13       23       169        529        299

∑      39      56        355       858        540

Substitute the values in the formula,

[tex]r=\dfrac{5\times 540-(39)\cdot (56)}{\sqrt{(5\times 355-(39)^2)(5\times 858-(56)^2)}}[/tex]

[tex]r=\dfrac{2700-2184}{\sqrt{(254)(1154)}}[/tex]

[tex]r=\dfrac{516}{\sqrt{293116}}[/tex]

[tex]r=\dfrac{516}{541.4018}[/tex]

[tex]r=0.9530[/tex]

Therefore, the value of r is 0.953.

ANSWER

[tex]\tan(x) = \frac{3\sqrt{7}}{7} [/tex]

EXPLANATION

[tex] \sin(x) = \frac{Opposite}{hypotenuse} [/tex]

[tex]\sin(x) = \frac{3}{4} [/tex]

This means the opposite side is 3 units and the hypotenuse is 4 units.

We use Pythagoras Theorem to find

[tex] { |ZX| }^{2} + {3}^{2} = {4}^{2} [/tex]

[tex]{ |ZX| }^{2} +9=16[/tex]

[tex]{ |ZX| }^{2} =16 - 9[/tex]

[tex]{ |ZX| }^{2} = 7[/tex]

[tex]{ |ZX| } = \sqrt{7} [/tex]

[tex] \tan(x) = \frac{opposite}{adjacent} [/tex]

[tex] \tan(x) = \frac{3}{ \sqrt{7} } [/tex]

[tex] \tan(x) = \frac{3}{ \sqrt{7} } \times \frac{\sqrt{7}}{\sqrt{7}} [/tex]

[tex]\tan(x) = \frac{3\sqrt{7}}{7} [/tex]

Final answer:

Given sin(X) = 3/4 in a right-angled triangle XYZ, by using trigonometric identities and the Pythagorean theorem, we find that tan(Y) is 1/3.

Explanation:

In triangle XYZ with angle Z being a right angle (90 degrees or π/2 radians), if we are given that sin(X) = 3/4, we can use trigonometric identities to find tan(Y). Since sin(X) is the ratio of the opposite side to the hypotenuse in a right-angled triangle, we have a side opposite angle X which is 3 units long and a hypotenuse that is 4 units long. From this, we can deduce that the side adjacent to angle X, which is also the side opposite to angle Y, is 1 unit long (using the Pythagorean theorem, as the square of the hypotenuse is equal to the sum of the squares of the other two sides: 3² + 1² = 4²).

Now, to find tan(Y), which is the ratio of the side opposite to Y to the side adjacent to Y, we just take the length of the side opposite to X (which is the same as the side adjacent to Y) and the length of the hypotenuse. Therefore, tan(Y) = opposite side / adjacent side, which in this case is 1/3.

Therefore we would need 100 beads with a mass of 10g to estimate a total mass of 1kg or 1000g

Their speeds are 45 mi/hr and 49 mi/hr

Answer:

The speed of the faster car is 68 miles/hr and speed of slower car is 40 miles/hr.

Step-by-step explanation:

Let the speed of the slower car be x

Now we are given that The speed of the faster car was 12 mph less than twice the speed of the other one.

So, Speed of faster car = 2x-12

Now we are given that In 6 hours the faster car got to San Diego, and by that time the slower one still was 168 miles away from the destination.

So, faster car completes the journey in 6 hours

Distance = [tex]Speed \times Time[/tex]

So, Distance traveled by faster car = [tex](2x-12)\times 6[/tex]

Distance traveled by slower car in 6 hours = [tex]Speed \times Time=6x[/tex]

Since we are given that when faster car completes the journey at that time slower car was 168 miles away from the destination .

A.T.Q

[tex](2x-12)\times 6-6x=168[/tex]

[tex]12x-72-6x=168[/tex]

[tex]6x-72=168[/tex]

[tex]6x=240[/tex]

[tex]x=\frac{240}{6}[/tex]

[tex]x=40[/tex]

So, speed of slower car is 40 miles/hr.

Speed of faster car = 2x-12 =2(40)-12=80-12=68 miles/hr.

Hence the speed of the faster car is 68 miles/hr and speed of slower car is 40 miles/hr.

Answer:

Obtuse isosceles

Step-by-step explanation:

Two sides are the same length, so we know this is an isosceles triangle.

To determine if it's acute, right, or obtuse, we can compare it to a right triangle using Pythagorean Theorem:

c² = a² + b²

c² = 3² + 3²

c² = 18

c = √18

So if this were a right triangle, c would be √18, which is somewhere between 4 and 5.

Since the long side is greater than √18, we know this must be an obtuse triangle.

So this is an obtuse isosceles.

To find out how many minutes it takes for 1 person to paint 1 wall, we can set up a proportion using the rate of 6 people painting 6 walls in 23 minutes. Cross-multiplying and solving for the unknown, we find that it would take approximately 3.83 minutes for 1 person to paint 1 wall.

This question falls under the subject of Mathematics and is suitable for students in Middle School. To solve this problem, we can use the concept of rate. We know that 6 people can paint 6 walls in 23 minutes.

We can set up a proportion to find out how many minutes it would take for 1 person to paint 1 wall. Let x represent the unknown time:

6 people / 23 minutes = 1 person / x minutes

Cross-multiplying, we get 6x = 23. Dividing both sides by 6, we find that x = 23/6. Therefore, it would take approximately 3.83 minutes for 1 person to paint 1 wall.

Options 1, 2, and 3 are valid based on the given information and calculations.

1. When added, the sum of the y-intercepts must be 8:

  - If the y-intercepts are denoted as b₁ and b₂ for f(x) and g(x) respectively, then . [tex]b_1 \times b_2 = 8[/tex].

2. When multiplied, the product of the y-intercepts must be 8:

  - This translates to [tex]b_1 \times b_2 = 8[/tex].

3. Either f(x) or g(x) has a positive rate of change and the other has a negative rate of change:

  - This implies that the slopes of the lines have opposite signs.

Checking the given U-turn points (-2, 8) and (8, 2). The slope (rate of change) between these points can be calculated as:

[tex]\[ m = \frac{change\:in\:y}{change\:in\:x} \][/tex]

[tex]\[ m = \frac{2 - 8}{8 - (-2)} = \frac{-6}{10} = -\frac{3}{5} \][/tex]

  - This statement is inconsistent with the calculated slope.

5. f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of -1:

  - This statement is also inconsistent with the calculated slope.
