How to calculate theta 2 d2 and first angle i will give 16 brainly points and maybe a bonus

For the quadrilateral ABCD the statement which proves that this quadrilateral is not a rectangle is (a) The slope of CD is "(-5-1)/(-5-5) = 3/5", and the "slope of DA is [3-(-5)]/[-3-(-5)] = 8/2", these "two-segments" are not perpendicular , so the shape is not a rectangle;

The coordinates of the "four-vertices" of the quadrilateral ABCD are :

A(-3,3), B(2,6), C(5, 1), D(-5,-5);

To prove whether the quadrilateral is a rectangle or not, we need to show that its adjacent sides are perpendicular and its diagonals are congruent.

In this question, we are given the coordinates of the four vertices of the quadrilateral.

To determine if it's a rectangle, we use the slope formula to find the slopes of the sides of the quadrilateral. If slopes of adjacent sides are "negative-reciprocals" of each other, then they are perpendicular. If the slopes of the diagonals are equal, then they are congruent.

Using the given coordinates, we find that the slope of CD is = (-5-1)/(-5-5) = 3/5, and

The slope of DA is = [3-(-5)]/[-3-(-5)] = 8/2. These two slopes are not negative reciprocals of each other, so CD and DA are not perpendicular.

So, the quadrilateral is not a rectangle.

Therefore, the correct option is (a).

Step-by-step explanation:

The thieves could take approximately 1555 bars of platinum.

Pt stands for platinum, an atomic number 78 chemical element. It is a thick, malleable, ductile, very inert, silvery-white-colored transition metal. Its name comes from the Spanish diminutive platina, meaning "silver"

One 1 lb bar of platinum has a volume of approximately 0.11 cubic feet. Assuming the density of platinum to be approximately 21 g/cm^3, the weight of 1 lb bar of platinum is approximately 0.45 kg. The maximum payload capacity of the small truck is approximately 317 kg. Hence, the thieves could take approximately 700 / 0.45 = 1555 bars of platinum.

The recursive formula for an, the nth term of the sequence is a(n) = a(n - 1) + 10 where a(1) = 10

From the question, we have the following parameters that can be used in our computation:

10, 20, 30, 40, . .

The above definitions imply that we simply add 10 to the previous term to get the current term

Using the above as a guide,

So, we have the following representation

a(n) = a(n - 1) + 10

Where

a(1) = 10

Hence, the sequence is a(n) = a(n - 1) + 10 where a(1) = 10

The code to calculate the sum of n terms in a series is shown below. To complete this code in C++ to find the sum of n terms of the series `a[i]` using a `for` loop, follow these steps:

Step 1: Include the header file "iostream".

Step 2: Use the std namespace.

Step 3: Declare the variables as double and an integer n.

Step 4: Request input from the user for n.

Step 5: Then, utilizing a for loop, request the user to input the values of the terms in the series a[i].

Step 6: Use the for loop again to determine the sum of the n terms of the series. At the conclusion of the loop, print the result to the console. In this code, we will ask the user for the value of n and the value of the n terms of the series `a[i]` and display the summation of the series using C++ program.

Answer:

The hot dog are $2.63

Step-by-step explanation:

Hot Dogs = H

Drinks = D

2H + 2D = 4

Divide both sides by 2

H + D = 2

Subtract D from either side

H = 2 -D

3H + D = 4.50

Plug in 2 - D for H

3(2- D ) + D = 4.50

6 - 3D + D = 4.50

6 - 4D = 4.50

Add 6 to either side

-4D = 10.50

Divide either side by -4

The correct answer is: 2. t=0.45a

Step-by-step explanation:

Let t be the price of apples

and a be the number of apples

The price and quantity are directly proportional

\(t \propto a\)

Removing the proportionality symbol introduces a proportionality constant in the equation

\(t = ka\)

So far we know that cost of 6 apples is $2.70

Putting in the equation

\(2.70 = k (6)\\k = \frac{2.70}{6}\\k = 0.45\)

Putting the values of k will give us:

\(t = 0.45a\)

Hence,

The correct answer is: 2. t=0.45a

Answer:

1022 of $10 tickets, 1326 of $20 tickets, 948 of VIP $30 tickets

Answer:

$10 tickets = 1,119

$20 tickets = 1,310

$30 tickets = 893

Step-by-step explanation:

x = $10 tickets, y = $20 tickets, z = $30 tickets

10x + 20y + 30z = 64,180

x + y + z = 3,322

y = 191 + x

therefore;

10x + 20(191+x) + 30z = 64,180     eqn 1

x + (191 + x) + z = 3,322         eqn 2

make z the subject of eqn 2

z = 3,322 - x - (191 + x)

z = 3,322 - 191 - x - x

z = 3131 - 2x

put z in eqn 1

10x + 20(191+x) + 30(3131 - 2x) = 64,180

10x + 3820 + 20x + 93,930 - 60x = 64,180

10x + 20x - 60x = 64,180 - 3820 - 93,930

-30x         =      -33,570

x      =   1,119

put x = 1,119 in z

z = 3131 - 2(1119)

z = 893

put x = 1,119 in y

y = 191 + 1119

  = 1,310

10(1119) + 20(1310) + 30(893) = 64,180

1119 + 1310 + 893 = 3,322

When NPV is zero, it does not dictate the specific IRR value or its relationship with the required return. IRR could be 0, greater than 0, greater than the required return, or less than 0.

When the net present value (NPV) is zero, it means that the present value of the cash inflows is equal to the present value of the cash outflows. In this scenario, the internal rate of return (IRR) can be evaluated using the following answer choices:
IRR = 0: This means that the IRR is equal to zero. However, it does not necessarily imply that the NPV is zero. NPV and IRR are independent metrics, so it is possible for the IRR to be zero even when the NPV is not zero.
IRR greater than the required return: The required return represents the minimum acceptable rate of return for an investment. If the IRR is greater than the required return, it implies that the project is expected to generate returns higher than the minimum required. In this case, the NPV would typically be positive.
IRR less than 0: This means that the IRR is negative. If the IRR is negative and the NPV is zero, it suggests that the project’s cash outflows are greater than its cash inflows, resulting in a zero NPV.
IRR greater than 0: This option states that the IRR is greater than zero. It does not directly relate to the NPV being zero. The NPV can be positive or negative when the IRR is greater than zero, depending on the specific cash flows and the required return.
Hence, when the NPV is zero, it does not determine a specific value for the IRR or its relationship with the required return. The IRR and NPV are separate evaluation metrics used to assess the profitability of an investment project.

The rate of growth of the value of the​ collector's item was 2.795% per year.Given that a toy tractor sold for $264 in 1975 and was sold again in 1990 for $466. We are to assume that the growth in the value v of the​ collector's item was exponential.

Assuming that the growth in the value of the​ collector's item was exponential, we can use the exponential growth formula, which is given as:P(t) = P0(1+r)^t

where, P0 = initial value, r = rate of growth or decay and P(t) = value after t years.In the given problem, let P0 = $264 (initial value), r = rate of growth and P(t) = $466 (value after 1990).

The time t is 1990 - 1975 = 15 years.

Hence, we can write the formula as:

$\(466 = $264(1 + r)^{15}\)

Dividing both sides by $264, we get:

\((1 + r)^{15} = $466/$264= 1.7651515.\)

Taking the 15th root on both sides, we get:1 + r = 1.02795r = 0.02795 or 2.795%.

Thus, the rate of growth of the value of the​ collector's item was 2.795% per year.

rounded to the nearest whole number a=346

the answer is 346

Therefore, a man will take 5280 steps of 2 foot 4 inches in walking 2 and 1/3 miles.

First, we need to convert 2 and 1/3 miles to feet.

1 mile = 5280 feet

2 and 1/3 miles = (2 * 5280) + (1/3 * 5280) = 10560 + 1760 = 12320 feet

Next, we need to convert 2 feet 4 inches to feet.

1 foot = 12 inches

2 feet 4 inches = 2 + (4/12) = 2.3333 feet (rounded to four decimal places)

Now, we can divide the total distance by the length of each step:
