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.
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.

What value of x completes the table?

3.6
13.3
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.

how many triangles have the following measurements? A=38, a=432, b=382
Using the Law of Sines, we determined that it is possible to form one triangle with the given measurements A=38°, a=432, and b=382. The calculation includes finding angle B and angle C, ensuring all triangle conditions are met.
To determine how many triangles can have the given measurements (A=38°, a=432, b=382), we need to check if these values satisfy the triangle inequalities and if they can form a possible triangle using the Law of Sines.
First, let's use the Law of Sines which states that:
sin(A)/a = sin(B)/b = sin(C)/c
Given:
A = 38° (angle)a = 432 (side opposite to angle A)b = 382 (side opposite to angle B)We can calculate angle B using:
sin(B) = (b × sin(A)) / a
sin(B) = (382 × sin(38°)) / 432 ≈ 0.556
Finding the arc sine of 0.556, we get:
B ≈ 33.8°
Now, we find angle C:
C = 180° - A - B ≈ 180° - 38° - 33.8° = 108.2°
Using the Law of Sines again to find side c:
c = (a × sin(C)) / sin(A)
c = (432 × sin(108.2°)) / sin(38°) ≈ 676.85
Thus, it's possible to form one such triangle with the given conditions.

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]
[tex]P(x) = 1.7x - 179.6[/tex]

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.
Which graph correctly solves the system of equations below? y = x2 + 2x + 3 y = −x2 + 3

Select the quadratic that has roots x=8 and x=-5
Answer:
Quadratic equation: [tex]x^2-3x-40=0[/tex]

A rectangle is inscribed in a square so that each vertex of the rectangle is located on one side of the square, and the sides of the rectangle are parallel to the diagonals of the square. Suppose that one side of the rectangle is twice the length of the other and that the diagonal of the square is 12 meters long. Find the sides of the rectangle.
9514 1404 393
Answer:
The sides of the rectangle are 4 and 8 meters long.
Explanation:
Please consider the attached figure. Both the rectangle and the square are symmetrical about the x- and y-axes, so we only need to consider the corner of the rectangle in one quadrant.
If the rectangle is twice as long as wide, then the distance of the corner to one axis (we chose y) will be twice the distance to the other axis. The locus of points for which that is true is the line with slope 1/2. The corner of the rectangle will be on that line.
If the corner of the rectangle is also on the square, then it will be located at the point of intersection of the line with slope 1/2 and the line representing the edge of the square. That point of intersection is the point (4, 2) on this graph. That is, half the length of the rectangle is 4 m, and half the width is 2 m. This indicates the sides of the rectangle are 8 m and 4 m in length.
__
The diagonals of the square are 12 m long, so orienting the square the way we have makes the x- and y-intercepts 6 units from the origin in each quadrant.
