A scuba divers dove 950 feet below the surface in 19 minutes what integer represents the average rate of change for this dive?

Answers

Answer 1
"950 feet in 19 minutes" can be expressed as the rate  (950/19) (ft/min), and is negative because the diver is descending (going downward).

Simplifying, -950/19 (ft/min) = -50 (ft/min)

Find the values of x on the curve y = cos x 2 + sin x at which the tangent is horizontal. (let n be an integer. enter your answers as a comma-separated list.)

Answers

Final answer:

To find the values of x on the given curve at which the tangent is horizontal, we need to find the points where the derivative of y with respect to x is equal to 0.

Explanation:

To find the values of x on the curve y = cos x^2 + sin x at which the tangent is horizontal, we need to find the points where the derivative of y with respect to x is equal to 0. The derivative of y is -2x sin x + cos x.

Setting the derivative equal to 0, we have -2x sin x + cos x = 0. Solving this equation will give us the values of x at which the tangent is horizontal.

Unfortunately, it is not possible to find exact solutions to this equation analytically. We can, however, solve it numerically using methods such as Newton's method or the bisection method.

In this problem, y = 1/(1 + c1e−x) is a one-parameter family of solutions of the first-order de y' = y − y2. find a solution of the first-order ivp consisting of this differential equation and the given initial condition. y(0) = − 1 8

Answers

The solution can be determined if we can specify the value of the arbitrary constant C₁. We do this by using the initial condition. When x=0, y is equal to -18. Substitute this to the general solution.

y = 1/(1 + C₁e⁻ˣ)
-18 = 1/(1 + C₁e⁰)
-18 = 1/(1+C₁)
C₁ = -1- 1/18 = -19/18

Therefore, the specific solution is:
y = 1/(1 - 19e⁻ˣ/18)

Sierra has a total of 61 dimes and quarters in her piggybank. She has 3 more quarters than dimes. The coins have a total value $10.90. How many dimes and how many quarters does she have? [hint: use the decimal values of the c coins to write an equation.]

Answers

Since you have two unknowns, you must formulate 2 equations in order to solve the system. Let x be the numbers of dimes and y be the number of quarters. The equations are:

x + y = 61
y = x + 3

Since a dime is 1/10 of a dollar and a quarter is 1/4 of a dollar,
(1/10)x + (1/4)y = 10.90

We made 3 equations. The system is overspecified. Let's just use the first two equations and apply it to the third for verification.

x + (x + 3) = 61
Solving for x,
x = 29
y = 29 + 3 = 32

Verifying,
(1/10)(29) + (1/4)(32) = 10.90

Hence, there are 29 dimes and 32 quarters.

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?

Answers

We are given the relation between the height (in feet) and the distance (in miles) as follows:
y = sqrt(1.5x + (x/5280)^2).

We want to know the height (x) that makes the distance (y) = 10 miles

So, we will simply substitute in the above equation with y = 10 and calculate x as follows:
10 = sqrt(1.5x + (x/5280)^2)
we will square both sides to get rid of the root:
100 = 1.5x + (x/5280)^2
1.5x + (x/5280)^2 - 100 = 0 
(x-66.11475)(x+7986.1147) = zero
either x = 66.11475 feet (accepted solution)
or x = -7986.1147 feet (rejected solution as no height is in negative)

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^2

Now, 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 feet

Therefore, a person needs to be approximately 593.4 feet above sea level to see 10 miles into the distance.

A new extended-life light bulb has an average service life of 750 hours, with a standard deviation of 50 hours. if the service life of these light bulbs approximates a normal distribution, about what percent of the distribution will be between 600 hours and 900 hours? 95% 68% 34% 99.7%

Answers

Approximately 99.7% of the light bulbs are expected to last between 600 and 900 hours, according to the empirical rule of normal distributions, as these values fall within +/- 3 standard deviations from the mean.

To determine what percent of the distribution of light bulbs will have a service life between 600 and 900 hours, we employ the empirical rule for normal distributions. If we know the mean (750 hours) and standard deviation (50 hours), we can calculate the number of standard deviations each of these values are from the mean:

(600 - 750) / 50 = -3 standard deviations (SD)

(900 - 750) / 50 = 3 standard deviations (SD)

According to the empirical rule (68-95-99.7 rule), approximately:

68% of the data falls within "+/- 1 SD"

95% of the data falls within "+/- 2 SD"

99.7% of the data falls within "+/- 3 SD"

Since 600 hours and 900 hours are three standard deviations away from the mean on either side, the percentage of light bulbs expected to last between these two values would be approximately 99.7%.

beth has a total of $6000 to invest, part at 6% simple interest and part at 8% simple interest. Her return for one year is $410. How much did she invest at each rate?

Answers

Since interest=investment*interest rate*time in years for simple interest, we know that there are 2 separate investments. If the amount invested at 6% simple interest is x dollars and the amount invested at 8% is y dollars, then we know that x+y=6000 since she spent all 6000 dollars on only 2 separate investments. Subtracting y from both sides, we get that 6000-y=x. In addition, we know that her interest for the 6% interest rate is x*0.06*1 as well as y*0.08*1 for the 8% simple interest. Since the total interest is 410$, we know that x*0.06*1+y*0.08*1=410. Since y=6000-x, we plug that in to get x*0.06+(6000-x)*0.08=410. Using the distributive property to expand, we get x*0.06+480-0.08x=410=-0.02*x+480. Subtracting 480 from both sides, we get -0.02*x=-70. After that, we can multiply both sides by -50 (since -0.02 times -50 is 1) to get x=3500=amount invested at 6%. Since the amount invested at 8% is 6000-x, that equals 6000-3500=2500

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

Answers

4.95 + 0.07x

The monthly charge is $ 4.95 ...and then there is the 7 cents per minute

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).

when 15 minus 3 is multiplied by a number the product is 2.

Answers

Final answer:

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.

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?

Answers

Final answer:

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.
