Given  Kruger National Park in Skukuza coordinate : (-24.98,31.58).

Nelson Mandela Musuem in Mpumalanga coordinate : (-29.82,31.58).

We need to find exactly in between given coordinates.

We know, mid - point formula :  

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right).[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-24.98,\:31.58\right),\:\left(x_2,\:y_2\right)=\left(-29.82,\:31.58\right)[/tex]

[tex]=\left(\frac{-29.82-24.98}{2},\:\frac{31.58+31.58}{2}\right)[/tex].

[tex]=\left(-27.4,\:31.58\right)[/tex].

To find Roy's total frequent flyer miles, add his current miles (10,368), the miles he'll earn from his trip to New York (2,832) and the miles he'll earn from his credit card spending (2 miles per dollar spent). The final expression for total miles is 13,200 + 2d where 'd' is the amount spent using the credit card.

Roy's total frequent flyer miles can be calculated by adding his existing miles, his incoming miles from his trip to New York, and the miles gained from using his credit card. Let's assume he spends 'd' dollars using his credit card.

Firstly, we combine the miles he already has and those he will earn from his round trip: 10,368 miles + 2,832 miles = 13,200 miles.

Secondly, we consider his credit card earnings. As he gains 2 miles per dollar spent, he will earn '2d' miles from his credit card spendings.

Finally, we add these together to get the total frequent flyer miles he will have: 13,200 miles + 2d miles. Therefore, the total miles that Roy will have depends on the amount 'd' he spends on his credit card.

In order to find the shaded region the first thing you have to do is find the area of the two small triangles, then find the area of the big triangle. Subtract the area of the small triangles from the big one and that is the area.

Step one: 11×12=132

Step two: 132÷2= 66

hello there this one was tricky i looked at it for sevrel minutes and solve dit

the answer is 50%

To obtain the same annual interest on both accounts, $3,600 should be invested at 9%, and $2,400 should be invested at 6%.

To solve this problem, we need to use the formula for simple interest, which is I = PRT, where P is the principal amount (the initial amount of money), R is the annual interest rate in decimal form, and T is the time the money is invested for in years. Here, we want both accounts to earn the same annual interest, so we'll let x be the amount of money invested at 9%, and 6000 - x be the amount of money invested at 6%. The annual interest for both should be the same, so:

x × 0.09 = (6000 - x) × 0.06

Solving for x, we get x = $3,600. So, $3,600 should be invested at 9%, and $2,400 ($6,000 - $3,600) should be invested at 6% to obtain the same annual interest.

We calculate the volume of the sphere to find the amount of gas it can hold, then we multiply this volume by the price per cubic foot to get the total cost of the gas, which is $3216.96.

The problem is asking us to determine the total value of gas in a spherical container given the radius of the sphere (container) and the cost of gas per cubic foot.

Firstly, we need to calculate the volume of the sphere using the formula: V = 4/3 * pi * r^3, where r is the radius of the sphere. Substituting the given radius, V = 4/3 * pi * 4^3 = 268.08 cubic feet

Then, we find the total value of the gas by multiplying the volume of the gas by the cost per cubic foot. So, the total value = volume * cost = 268.08 * 12 = $3216.96

The total value of the gas in the container is $3216.96.

To find the total value of the gas in the container, we first need to calculate the volume of the gas.

The formula to find the volume of a sphere is V = (4/3) * π * r^3, where r is the radius of the sphere.

Plugging in the given radius of 4 ft, we get V = (4/3) * π * (4^3) = 268.08 ft^3.

Next, we multiply the volume of the gas by the cost per cubic foot to find the total value.

Multiplying 268.08 ft^3 by $12/ft^3, we get a total value of $3216.96.

Therefore, the total value of the gas in the container is $3216.96.

Answer: 3 m/s

Step-by-step explanation:

1) the instantaneous speed is the slop at t = 6 secs

2) since its a straight line, the slop of the line is the speed and its constant.

#1. (6n) to the second power = (6^2) * (n^2)

n^2 means n to the second power, by the way

#2. (1+7n) to the second power = 1+14n+49n^2

Step-by-step explanation: You would just seperated square for the first one, since it involves the multiplication of squares, which is the same as squaring the product.

For the second one, you would expand the product to a^2+2ab+b^2, which is the same as 1^2 + 2(1*7n)+7n^2, which simplifies to 1+14n+49n^2

Answer:

37.5%

Step-by-step explanation:

subtract 80 by 50 to find the increase of money

80-50=30

then divide the number you got by the increase of price Wich is 80

30÷80=0.375

then multiply 0.375 by 100 to put it in percentage form

0.375x100=37.5%

The answer would be C since 3.00 would be the initial cost and 5 would be the hourly rate, with x being the amount of hours the car is in the parking lot.

The answer is C. In this situation, slope means the rate of change of the cost of parking in the lot is 5 dollar per hour.

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. That means the change in y due to change in x.

In an equation, y = mx + c, slope is m.

Answer:

a) Parallel when a = -2/3

b) Perpendicular when a = 6

Explanation:

a)  For two parallel lines slopes are equal.

  So, 6y=−2x+4 and 2y=ax−5 parallel if they are slopes equal.

  Slope of 6y=−2x+4, comparing with y = mx + c

     So, m = -2/6 = =-1/3

  For 6y=−2x+4 and 2y=ax−5 to b parallel we have slope of 2y=ax−5 equal to -1/3

   Slope of 2y=ax−5

           m = a/2

    We have a/2 = -1/3

                    a = -2/3

b) For perpendicular lines product of slope is -1.

   So we have

               [tex]\frac{a}{2} *\frac{-1}{3} =-1\\ \\ a=6[/tex]    

The value of 'a' that would make the graphs of the equations 6y = -2x + 4 and 2y = ax - 5 parallel is -1/3. Meanwhile, the value of 'a' that would make them perpendicular is 3.

The question you've asked is about finding the values of a for which two graphs represented by the equations 6y = -2x + 4 and 2y = ax - 5 are either parallel or perpendicular. To solve this, we need to understand and apply the concept of slope in straight-line equations.

Firstly, rewrite the given equations in the form of y = mx + b, where m is the slope. For the first equation, it becomes y = -1/3x + 2/3, so the slope is -1/3.

Parallel lines have the same slope. Therefore, the value of 'a' for the second equation to be parallel with the first needs to be -1/3. Conversely, perpendicular lines have slopes that multiply to -1. Thus, for the second line to be perpendicular to the first, 'a' would have to be the negative reciprocal of -1/3, which is 3.
