The line segment AB has point B(x, y) = (11, - 4) as its other endpoint.

Herein we find the case of a line segment, of which the coordinates of its midpoint and one of its endpoints are known. Midpoint and endpoints are related by following expression:

0.5 · A(x, y) + 0.5 · B(x, y) = M(x, y)

Where:

If we know that A(x, y) = (- 1, 8) and M(x, y) = (5, 2), then the coordinates of the other midpoint are:

0.5 · (- 1, 8) + 0.5 · B(x, y) = (5, 2)

(- 1, 8) + B(x, y) = 2 · (5, 2)

(- 1, 8) + B(x, y) = (10, 4)

B(x, y) = (11, - 4)

The point B(x, y) = (11, - 4) is an endpoint of line segment AB.

The child has 14 quarters and 28 dimes if child's bank contains $6.30 in dimes and quarters.

What is Algebraic expression ?

Algebraic expression can be defined as the combination of variables and constants.

With coin problems you need to keep track of the count of the coins and the value.

d = number of dimes

10d = value of the dimes in cents

q = number of quarters

25q = value of the quarters in cents

10d + 25q = 630 cents

d = 2q

substitute

10(2q) + 25q = 630

20q + 25q = 630

45q = 630

q = 14

d = 2q

d = 2*14 = 28

Check the values to be sure this answer is right.

25(14) = 350 cents

10(28) = 280 cents

total = 630 cents

Answer: To check if Jose has enough string for his project, we need to add the lengths of the strings he has and compare it to the amount of string he needs for the project.

The length of the first string is 9 1/2 feet, the second string is 3 1/4 feet and the third string is 4.5 feet.

To add these lengths we need to convert them all to the same unit of measurement.

3 1/4 feet can be converted to 3.25 feet

So the total length of the strings Jose has is 9 1/2 + 3.25 + 4.5 = 17.25 feet

Jose needs 20 1/3 feet of string for his project, and he has 17.25 feet of string.

So he doesn't have enough string for his project.

The solution to the simultaneous equation is x = 38 and y = 8

From the information given, we have the equations;

From equation (1), make 'x' the subject of formula;

4x = 48 - 5y

Divide both sides by 4

x = 48 - 5y/4

Substitute the value x in equation (2)

7(48 - 5y/4) - 3y = -10

expand the bracket

336 - 35y/4 - 3y = -10

Find the lowest common multiple

336 - 35y - 12y/4 = -10

336 - 47y/4 = -10

cross multiply

336 - 47y = -40

collect like terms

-47y = 376

y = 8

Substitute the value into equation 3

Answer: 2.294524311274043, 4.294524311274043, 6.294524311274043 and 8.294524311274043 radians.

Step-by-step explanation: We can start by isolating the sin function on one side of the equation:

sin (2x-4) = 2/3

Next, we can use the inverse sine function (sin^-1) to find the value of 2x-4:

2x-4 = sin^-1(2/3)

We know that the domain of the inverse sine function is [-1,1], so the value of 2/3 falls in that range. To find the value of x, we can add 4 to both sides and divide both sides by 2:

x = (sin^-1(2/3) + 4) / 2

The value of sin^-1(2/3) is approximately 0.5890486225480862 radians and that's the first solution in the range [0, pi], and we can add multiples of pi to get the other solutions.

x = (0.5890486225480862 + 4) / 2 = 2.294524311274043 radians (in the range [0, pi])

x = (0.5890486225480862 + 4 + pi) / 2 = 4.294524311274043 radians (in the range [pi, 2pi])

x = (0.5890486225480862 + 4 + 2pi) / 2 = 6.294524311274043 radians (in the range [2pi, 3pi])

x = (0.5890486225480862 + 4 + 3pi) / 2 = 8.294524311274043 radians (in the range [3pi, 4*pi])

So there are four solutions to this equation: 2.294524311274043, 4.294524311274043, 6.294524311274043 and 8.294524311274043 radians.

The function after transformation is G(x) = -5 ln (x+6) is the correct answer.

The correct answer is an option (C)

Here, the function is f(x) = ln x

A function f(x) is stretched vertically by a factor of 5.

As we know for a vertical stretch, we need to multiply the whole function by the factor of stretching.

If the stretching factor is m, then after stretching the function becomes

⇒ m × f(x)

Here, stretching factor m = 5

So the transformed function would be,

G(x) = 5 f(x)

⇒ G(x) = 5 ln x

Now, function is reflected across the x-axis, so the function becomes

⇒ G(x) = -5 ln (x+6)

Then the function is shifted by 6 units left, so after translation the function becomes

⇒ G(x) = -5 ln (x+6)

Thus, we can conclude that the function f(x) = ln x after transformation would be G(x) = -5 ln (x+6) is the correct answer.

Answer:

  305 miles

Step-by-step explanation:

You want to know how far Dylan travelled if he drove 50 mph for 3.5 hours and 65 mph for 2 hours.

Distance is the product of speed and time. The total distance Dylan travelled will be the sum of lengths of the legs of his trip.

  distance = speed · time

  total distance = speed1 · time1 + speed2 · time2

  = (50 mi/h)(3.5 h) +(65 mi/h)(2 h) = 305 mi

Dylan travelled a total of 305 miles.

It will take 48 hours, to fill the tank if both pipes are left open simultaneously.

We are given the following data -

The time taken to fill the tank by inlet pipe = 12 hrs

so, the rate of filling = 1/12

The time taken to empty the tank by drain pipe = 16 hrs

so, the rate of emptying = - 1/16

Therefore, the total work done by both pipes can be given by the following formula -

(1/rate of filling) + (1/rate of emptying) = (1/rate of net change)

1/12 + (-1/16) = (1/Rn)

Therefore, (1/Rn) = 1/12 - 1/16 = 1/48

To find how long it will take to fill the tank, we need to find the reciprocal of the rate of net change:

1/Rn = 1/(1/48)

Rn = 48

So it will take 48 hours, to fill the tank if both pipes are left open.
