The expression 4.95+0.07x models A household monthly long distance charges where x represents the number of minutes of long-distance calls during the month what are the monthly charges for each number of long distance minutes
The expression provided models the monthly long distance telephone charges, with a fixed fee of $4.95 plus $0.07 per minute of call time. To determine the monthly charge, multiply the number of minutes by $0.07 and add the result to the base charge of $4.95.
The given expression 4.95 + 0.07x represents a model for calculating a household's monthly long distance telephone charges, where x is the number of minutes of long-distance calls. To find the monthly charges for any number of minutes (x), we simply plug in the value of x and calculate the total cost.
If a household uses 0 minutes, the cost would be $4.95 (since 4.95 + 0.07(0) = 4.95).For 100 minutes of use, the cost would be $4.95 + (0.07 x 100) = $4.95 + $7.00 = $11.95.The formula incorporates a fixed fee of $4.95, which we can see as the base charge regardless of usage, plus a variable component that depends on the number of minutes used (0.07 times the number of minutes).

Matlab the equation of a circle with its center at x=3 and y=2 is given by , where r is the radius of the circle. first derive the equation(symbolically) of the tangent line to the circle at the point on the upper part of the circle ( and ). then for specific values of r, , , make a plot of the circle and the tangent line. (r=9, )
To derive the equation of the tangent line to the circle, differentiate the circle equation implicitly and substitute the coordinates of a point on the circle to find the specific equation. For r = 9 and x = 3, the specific equation of the tangent line is y = 9 + 3x. Use software like Matlab or a graphing calculator to plot the circle and the tangent line.
Explanation:To derive the equation of the tangent line to the circle at the upper part, we need to find the slope of the tangent line and the coordinates of a point on the circle. The slope of a tangent line to a circle at a given point is the negative reciprocal of the slope of the radius from the center to that point. In this case, the center of the circle is (3, 2) and the radius is 9, so the equation of the circle is (x-3)^2 + (y-2)^2 = 9^2. By differentiating this equation implicitly, we can find the slope of the tangent line.
The equation of the circle is (x-3)^2 + (y-2)^2 = 81.
Differentiating implicitly with respect to x:
2(x-3) + 2(y-2) dy/dx = 0
Simplifying:
(x-3) + (y-2) dy/dx = 0
(y-2) dy/dx = 3-x
dy/dx = (3-x) / (y-2)
To find the slope of the tangent line at the upper part of the circle, we substitute y = 2 + sqrt(81 - (x-3)^2) into the derived equation of dy/dx. After simplifying, we can substitute the coordinates of a point on the circle to find the specific equation of the tangent line.
For r = 9 and x = 3, the specific equation of the tangent line is y = 9 + 3x.
To make a plot of the circle and the tangent line, we graph both the circle equation and the tangent line equation using a software like Matlab or a graphing calculator.

when 15 minus 3 is multiplied by a number the product is 2.
Based on the provided information, you can find the value of the unknown by performing the operation (15-3), which is 12, and then dividing the product by this number. The result is 1/6, which is the number that fulfills the conditions stated in the problem.
Explanation:The subject of this problem is middle school math, specifically dealing with equations and unknowns. The problem states that 'when 15 minus 3 is multiplied by a number the product is 2'. To solve this, we use basic algebraic manipulation.
First, perform the operation 15 minus 3, which equals 12. Then, we state the problem algebraically: 12 times a certain number (let's call it 'x') equals 2. Stated as an equation, it would be 12x = 2.
To find the value of 'x', we need to isolate 'x' on one side of the equation, so we divide both sides of the equation by 12. This leaves us with x = 2/12. Simplifying the fraction gives x = 1/6.
In conclusion, the number that when multiplied by 12 (resulting from 15 minus 3), gives us a product of 2 is 1/6.

When dividing 592 by 9.25, how many zeros will be placed in the dividend?
No doubt, the expeced answer is 2. This is because you would ordinarily change the problem to 59200/925 for long division by hand.
For this quotient, you don't need any, because the quotient is 64, a multiple of 4, so the numbers being subtracted are always integers.
_____
If you were dividing 591 by 9.25, you would need an infinite number of zeros—because the decimal portion of the quotient is a repeating decimal with a period of 3 digits.

Find the dimensions of a rectangle with a perimeter of 148 feet that has the maximum area
The dimensions of the rectangle with a perimeter of 148 feet that has the maximum area would be 37 feet by 37 feet, forming a square. The maximum area of the rectangle is 1369 square feet.
Explanation:To find the dimensions of a rectangle with a known perimeter and the maximum area, first understand that the rectangle with the maximum area is a square. In this case, the perimeter is 148 feet.
To calculate the side length of the square, divide the perimeter by 4. Thus, the side of the square would be 148 feet / 4 = 37 feet. Therefore, the maximum area will be achieved when each side of the rectangle is 37 feet long, making it a square with these dimensions.
The maximum area of such a rectangle, which in this case is a square, is obtained by squaring the side length: Area = side × side = 37 feet × 37 feet = 1369 square feet.

Saeed bought 21 1/2 lb. of ground beef. he used 1/4 of the beef to make tacos and the remaining 2/3 of the remainder to make quarter pound burgers. how many burgers did he make?
Saeed made 42 2/3 burgers.
Explanation:To solve this problem, we need to find out how much ground beef Saeed used to make tacos and how much he used to make quarter-pound burgers. Let's break it down step-by-step:
1. Saeed bought 21 1/2 lb of ground beef.
2. He used 1/4 of the beef to make tacos. So, 1/4 of 21 1/2 lb is (1/4) * 21 1/2 lb = 5 3/8 lb.
3. The remaining beef is 21 1/2 lb - 5 3/8 lb = 16 1/8 lb.
4. Saeed used 2/3 of the remaining beef to make quarter-pound burgers. So, 2/3 of 16 1/8 lb is (2/3) * 16 1/8 lb = 32/3 lb = 10 2/3 lb.
5. To find the number of quarter-pound burgers, we divide the weight of the beef used for burgers by the weight of each burger. Since each burger weighs 1/4 lb, we divide 10 2/3 lb by 1/4 lb to get:
10 2/3 lb ÷ 1/4 lb = 10 2/3 lb * 4 lb/1 = 42 2/3 burgers.
Therefore, Saeed made 42 2/3 burgers.
Final answer:
Saeed used 1/4 of the ground beef for tacos and the remaining 2/3 for quarter pound burgers. After calculating, we determined that he was able to make 43 quarter pound burgers.
Explanation:
To solve Saeed's ground beef problem, we need to perform sequenced calculations to determine how much beef was used for tacos, and how many quarter pound burgers were made with the remaining beef.
First, Saeed used 1/4 of the 21 1/2 lb of beef for tacos. To find out how much that is, multiply 21.5 lb by 1/4:
21.5 lb × 1/4 = 5.375 lb for tacos
Next, we subtract this amount from the original to find the remainder:
21.5 lb - 5.375 lb = 16.125 lb remaining
Now, Saeed uses 2/3 of the remaining beef for burgers. So, we calculate:
16.125 lb × 2/3 = 10.75 lb for burgers
Since each burger is a quarter pound, we divide the weight used for burgers by 1/4 to find out how many burgers he made:
10.75 lb ÷ 1/4 lb per burger = 43 burgers
Therefore, Saeed made 43 quarter pound burgers.

If you stand on a ship in a calm sea, then your height x (in feet) above sea level is related to the farthest distance y (in miles) that you can see by the equation: y=sqrt (1.5x+(x/5280)^2) how high up do you have to be to be able to see 10mi?
Final answer:
To see 10 miles into the distance, one must be approximately 593.4 feet above sea level. This is calculated by substituting y = 10 into the given formula and solving for x.
Explanation:
The student's question involves finding how high above sea level they must be to see a distance of 10 miles. We begin with the equation given:
y = sqrt(1.5x + (x/5280)^2)
We need to solve this equation for x when y is 10 miles. First, we substitute 10 for y and square both sides of the equation to eliminate the square root:
10^2 = 1.5x + (x/5280)^2100 = 1.5x + x^2/(5280^2)Multiply through by 5280^2 to simplify:
100(5280^2) = 1.5x(5280^2) + x^2100(5280^2) = 7920x^2 + x^2100(5280^2) = 7921x^2Now, we solve for x:
x^2 = 100(5280^2) / 7921x = sqrt(100(5280^2) / 7921)x ≈ sqrt(2787840000 / 7921)x ≈ sqrt(352000)x ≈ 593.4 feetTherefore, a person needs to be approximately 593.4 feet above sea level to see 10 miles into the distance.
