what is the circumference of a circular pond with a radius of 14 meters?
A rectangular room is 14 feet by 20 feet. The ceiling is 8 feet high. How do you find the length and width of the smaller and larger wall?
We need to visualize the box by using a diagram attached with this problem.
[tex] Length = 14 \; feet [/tex]
[tex] Width = 20 \; feet [/tex]
[tex] Height = 8 \; feet [/tex]
The blue is smaller rectangle and brown is the larger rectangle
Conclusion:
Length of smaller wall (in blue color) is 14 feet
Width of smaller wall (in blue color) is 8 feet
Length of Larger wall (in brown color) is 20 feet
Width of the Larger wall (in brown color) is 8 feet

Suppose f and g are continuous functions such that g(3) = 6 and lim x → 3 [3f(x) + f(x)g(x)] = 54. find f(3).
When f and g are continuous functions such that g(3) = 6 and lim x → 3 [3f(x) + f(x)g(x)] = 54 the value of f(3) is 6.
Rewrite the given limit as: lim x→3 [3f(x) + f(x)g(x)] = lim x→3 [3f(x)] + lim x→3 [f(x)g(x)]
Substitute the limits using continuity: 54 = 3 lim x→3 f(x) + lim x→3 f(x) ⋅ lim x→3 g(x) 54 = 3f(3) + f(3) ⋅ 6 (since lim x→3 f(x) = f(3) and lim x→3 g(x) = 6)
Combine like terms: 54 = 9f(3)
Divide both sides by 9: f(3) = 6
Therefore, f(3) = 6.
Which graph correctly solves the system of equations below? y = x2 + 2x + 3 y = −x2 + 3
Answer:
Graphs are attached for both solutions.
Step-by-step explanation:
Using a graphing calculator, we can graph both equations and then find the solutions.
The solutions to the system of equations will be the points of intersection of the graphs. There are two points of intersection, so there are two solutions. One of them is at (0, 3); the other is at (-1, 2).
What is the approximate area of the circle shown below 3.5cm
Answer:
D. 38.5 cm²
Step-by-step explanation:
The area of a circle is given by:
A = πr²
where r is the radius of the circle.
From the given figure,
Radius of the circle is r = 3.5 cm.
Therefore, the area of the circle is:
⇒A = 3.14 × (3.5 cm)² = 38.5 cm²
Thus, the correct option is D.
Henry lives in Mississippi, which has a sales tax of 7%. He just bought a bed whose full price was $1600, but he got 30% off, because the store was having a sale. What was the total amount that Henry paid?
A.) $1120.00
B.) $1198.40
C.) $1934.40
D.) $1712.00
Answer:
B.) $1198.40
Step-by-step explanation:
Given,
The original price of the bed = $ 1600,
Since, in sale, he got 30 % off,
The price of bed in sale = The original price of the bed - 30 % of the original price of the bed
[tex]= 1600 - 30\% \text{ of } 1600[/tex]
[tex]=1600-\frac{30\times 1600}{100}[/tex]
[tex]=1600-\frac{48000}{100}[/tex]
[tex]=1600-480=\$ 1120[/tex]
Also, there is a sales tax of 7 % ,
Thus, the final price of the bed = The price of bed in sale + 7 % of the price of bed in sale
[tex]=1120+\frac{7\times 1120}{100}[/tex]
[tex]=1120+\frac{7840}{100}[/tex]
[tex]=1120+78.40=\$1198.40[/tex]
Hence, he paid $ 1198.40.

Step-by-step explanation:
We are given two roots of the quadratic equation and we need to find the quadratic equation.
If roots are a and b then equation
[tex]x^2-(\text{sum of roots})x+\text{Product of root}=0[/tex]
Roots are x=8 and x=-5

in y=16500-1500x what is the rate of change
Final answer:
The rate of change in the linear equation y=16500-1500x is -1500, indicating that y decreases by 1500 for each increase in x by one unit. This represents the slope of the line and shows a direct relationship between x and y in a regression line context.
Explanation:
In the equation y=16500-1500x, the rate of change is represented by the coefficient of x, which is -1500. This means that for each unit increase in x, the value of y decreases by 1500. Contrary to the provided reference which mistakenly lists the slope as -105,000/1, the actual rate of change in this linear equation is -1500. Such linear equations are often used to describe a regression line, which showcases the average relationship between the variables x and y in a scatter diagram.
The slope of a line in a linear equation like this one is crucial for understanding how changes in one variable affect another. This linear model is straightforward and does not change across different values of x, unlike in nonlinear models where the rate of change can vary.

The areas of a figure and its transformed image are the same. Which transformation could NOT have been applied to the original figure to create the image?
A. Rotation of 90
B. Reflection across a horizontal line
C. Dilation by a scale factor of 0.5
D. Translation down 4 and then right 1
The transformation that could NOT have been applied to the original figure to create an image with the same area is:
C. Dilation by a scale factor of 0.5.
To determine which transformation could NOT have been applied to the original figure to create the image with the same area, let's analyze each option:
A. Rotation of 90 degrees: When a figure is rotated by 90 degrees, the area remains the same.
This transformation is possible.
B. Reflection across a horizontal line: A reflection across a horizontal line (a horizontal flip) preserves the area of the figure.
This transformation is possible.
C. Dilation by a scale factor of 0.5: Dilation involves scaling a figure by a certain factor.
If a figure is dilated by a scale factor of 0.5, both its length and width are reduced to half, which means the area is reduced to one-fourth of the original area.
This transformation is not possible because it changes the area.
D. Translation down 4 and then right 1: A translation moves a figure without changing its size or shape. A translation down 4 and then right 1 would not change the area of the figure, as it simply shifts the figure's position.
This transformation is possible.
So, the transformation that could NOT have been applied to the original figure to create an image with the same area is:
C. Dilation by a scale factor of 0.5
Dilation by a scale factor of 0.5 would change the area, making it incompatible with the condition that the areas of the original figure and its image are the same.

Rachel invested $15,000 in a nine-year CD giving 8.5% interest, but needed to withdraw $4,000 after two years. If the CD's penalty for withdrawal was six months' worth of interest on the amount withdrawn, how much money did Rachel have when the CD reached maturity, not including the amount she withdrew? Round answer to the nearest whole dollar.
a.
$19,925
b.
$8,795
c.
$19,795
d.
$12,965
Answer:
Option a ) $19,925
Step-by-step explanation:
$15,000 was invested for 9 years and then $4,000 was withdrawn after 2 years.
So, $11,000 was invested for entire 9 years and $4,000 was invested for 2 years.
Interest on $11,000 for 9 years @ 8.5 % = 11,000 X 9 X 8.5 % = $8,415
Interest on $4,000 for 2 years @ 8.5 % = 4,000 X 2 X 8.5 % = $680
Penalty for withdrawing $4,000 = 4000 X 8.5 % X 0.5 = $170
Total amount that Rachel will get on maturity = $11,000 + total interest - penalty = $11,000 + $8,415 + $680 - $170 = $19,925
Hope it helps.

To make a profit, a company’s revenue must be greater than its operating costs. The company’s revenue is modeled by the expression 7.5x – 100, where x represents the number of items sold. The company’s operation costs are modeled by the expression 79.86 + 5.8x. How many items does the company need to sell to make a profit? The inequality that will determine the number of items that need to be sold to make a profit is ? The solution to the inequality is ? The company must sell at least? items to make a profit.
Using the profit concept, it is found that:
The inequality is: [tex]1.7x - 179.6 > 0[/tex]The solution is [tex]x > 105.6[/tex]The company must sell at least 106 items to make a profit.Profit is revenue subtracted by operations costs, that is:
[tex]P(x) = R(x) - C(x)[/tex]
In this problem, the functions are:
[tex]R(x) = 7.5x - 100[/tex]
[tex]C(s) = 79.6 + 5.8x[/tex]
Thus, the profit function is:
[tex]P(x) = R(x) - C(x)[/tex]
[tex]P(x) = 7.5x - 100 - 79.6 - 5.8x[/tex]

Answer:
The correct option is 1.
Step-by-step explanation:
It is given that the glacier is moving at a rate of 0.3 inches every hour. It means the average rate of change is 0.3.
Let d is the total moved distance of glacier and t is number of hours. Then the total moved distance of glacier after t hours is defined as
[tex]d=0.3t[/tex]
At t=1,
[tex]d=0.3(1)=0.3[/tex]
At t=2,
[tex]d=0.3(2)=0.6[/tex]
At t=3,
[tex]d=0.3(3)=0.9[/tex]
At t=4,
[tex]d=0.3(4)=1.2[/tex]
Total moved distance of glacier after 4 hours is 1.2 inches.
The value of x is 1.2. Therefore the correct option is 1.
