The measure of angle A can be calculated using trigonometry and the components of a known vector. The relationship of the components forms a right triangle, the properties of which can be used to find the measure of angle A.

The measure of angle A can be calculated using trigonometry if we know the distances from the problem. By knowing the scalar components Ax and Ay of vector A, we can find its magnitude and direction angle. In this case, the direction is the angle the vector forms with the positive direction on the x-axis, measured in the counterclockwise direction. The lengths A, Ax, and Ay form a right triangle, related by the Pythagorean theorem.

If the vector A is known, then its magnitude A and its angle are known. To find Ax and Ay, we use the following relationships for a right triangle: Ax = Acose. If the vector lies in the first or the fourth quadrant, where component Ax is positive, angle A is identical to the direction angle. Conversely, when the vector lies in the second or third quadrant, where component Ax is negative, the direction angle is A = 0 + 180°.

The measure of angle A in the given figure is equal to 20 degrees.

To solve this question we can use the property of a triangle that the sum of all angles in a triangle is equal to 180 degrees.

We have been given three different angles in this figure which are: 90 degrees, 71x-1, and 20x.

Let us find the value of x before finding the value of angle A

71x-1 + 20x + 90 = 180

71x + 20x = 180 - 90 + 1

91x = 91

x = 1

Now we can calculate the value of angle A as:

20x

= 20 (1)

= 20 degrees

The measure of angle A is 20 degrees.

Answer:

500,000 grams

Step-by-step explanation:

1 kg = 1,000 g

500*1,000=500,000

Answer:

I believe the correct answer would be 220 meters.

Step-by-step explanation:

If one centimeter equals 2 meters, then you would have to multiply the width (5.5 cm.) by 2 and the length (10 cm.) by 2. After you multiply those, you get 11 meters for the width and 20 meters for the length. You then multiply those by each other, so 11x20, and you get 220.

The actual length and width will be 20 meters and 11 meters. Then the area of the rectangle will be 220 square meters.

Let L be the length and W be the width of the rectangle.

Then the area of the rectangle will be

Area of the rectangle = L×W units

The scale for a drawing of the tennis court is 1 centimeter = 2 meters. Then the area of the actual tennis court will be

Width = 5.5 cm

Length = 10 cm

Then the actual length and width will be

L = 10 x 2 = 20 meters

W = 5.5 x 2 = 11 meters

Then the area of the rectangle will be

A = 20 x 11

A = 220 square meters

The electric force of a charged balloon sticking to the ceiling is due to the interaction between the balloon and the induced positive charge in the ceiling. This force is related to the principle of electrostatics and can theoretically be calculated using Coulomb's Law, but would require more details. However, for the balloon to remain stuck to the ceiling, this electrostatic force must be greater than the weight of the balloon.

To calculate the electric force of a charged balloon sticking to the ceiling, you first need to consider the scenario as an interaction between the charged balloon and the induced charge in the ceiling. This scenario is related to the principle of electrostatics, where like charges repel and different charges attract. It is the electrostatic force that is making the balloon stick to the ceiling.

The balloon gets charged by picking up extra electrons (negative charge) when rubbed. When brought near the ceiling, these extra electrons in the balloon repel the electrons in the ceiling, causing the area of the ceiling near the balloon to be positively charged. This induced positive charge in the ceiling then attracts the negatively charged balloon. The force between the balloon and the ceiling can be caluclated using Coulomb's Law, which states that the force between two charges is directly proportional to the product of their charges, and inversely proportional to the square of the distance between them. However, to accurately calculate this force using Coulomb's law, we need more information such as the amount of charge on the balloon and the distance from the balloon to the ceiling.

Finally, for a balloon to stick to the ceiling, the electrostatic force must be greater than the weight of the balloon. The weight of the balloon can be calculated using the formula Weight = mass x gravity. In this case, the mass of the balloon is 0.020kg and the gravitational force is approximately 9.8 m/s². Therefore, the weight is 0.020kg x 9.8 m/s² = 0.196N. So for the balloon to stick to the ceiling, the electrostatic force must be greater than 0.196 N.

Answer:

C

Step-by-step explanation:

Before multiplying perform the addition in the parenthesis

2 [tex]\frac{1}{6}[/tex] + [tex]\frac{7}{8}[/tex]

Change the mixed number to an improper fraction

2 [tex]\frac{1}{6}[/tex] = [tex]\frac{13}{6}[/tex], thus

[tex]\frac{13}{6}[/tex] + [tex]\frac{7}{8}[/tex]

The fractions require to have a common denominator before adding

The lowest common multiple of 6 and 8 is 24

Multiply numerator/denominator of first fraction by 4

Multiply the numerator/denominator of the second fraction by 3

= [tex]\frac{13(4)}{6(4)}[/tex] + [tex]\frac{7(3)}{8(3)}[/tex]

= [tex]\frac{52}{24}[/tex] + [tex]\frac{21}{24}[/tex] = [tex]\frac{73}{24}[/tex]

Now multiply this result by [tex]\frac{1}{2}[/tex], thus

[tex]\frac{1}{2}[/tex] × [tex]\frac{73}{24}[/tex]

= [tex]\frac{1(73)}{2(24)}[/tex]

= [tex]\frac{73}{48}[/tex]

Answer:

60 square units.

Step-by-step explanation:

First, work out what the length of of the other leg is

[tex]120 \times 2 = 240 \: 240 \div \: 24 = 10[/tex]

Next, to work out the hypotenuse you add the squares of the legs.

[tex] {24}^{2} + 10 ^{2} = 676[/tex]

Then square root the answer from the previous calculation.

[tex] \sqrt{676} = 26[/tex]

And finally add the sides together.

26+24+10= 60 square units

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side. Then the perimeter of the triangle is 60 units.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

A right triangle has an area of 120 square units and a leg length of 24 units.

Then the other length of the triangle will be

Area = 1/2 (b x h)

120 = 1/2 (24 h)

240 = 24h

h = 10

Then the third length of the triangle will be given by the Pythagoras theorem.

H² = b² + h²

H² = 24² + 10²

H² = 576 + 100

H² = 676

H = 26

Then the perimeter of the right-angle triangle will be

Perimeter = 10 + 24 + 26

Perimeter = 60 units

[tex]a_{n}=1.2 \times(2.5)^{n-1}[/tex]

Step-by-step explanation:

If we observe the given sequence, we find that the ratio of two consecutive terms is the same. i.e.

[tex]\frac{3}{1.2}=2.5\\\\\frac{7.5}{3}=2.5\\\\ \frac{18.75}{7.5}=2.5[/tex]

Such a sequence in which the ratio of consecutive terms remain the same is know as Geometric Sequence. Following formula is used to represent a Geometric Sequence:

[tex]a_{n}=a_{1}\times(r)^{n-1}[/tex]

Here:

[tex]a_{n}[/tex] is the general term. Using the value of n =1,2,3 ... will give us the term of the sequence.

[tex]a_{1}[/tex] is the first term which is 1.2 in this case.

r represents the common ratio which is 2.5.

Using these values we get:

[tex]a_{n}=1.2 \times(2.5)^{n-1}[/tex]

This formula can be used to represent the given sequence.

Answer:

The pennies

Step-by-step explanation:

We can create a geometric equation for the pennies and an arithmetic equation for the dollars.

The format for a geometric equation is

[tex]y=a_1(\frac{1-r^n}{1-r} )[/tex]

If we plug in the values we already know we should get the equation.

[tex]y=2^x-1[/tex]

Now we can plug in the number of days in a year for [tex]x[/tex] to find how much money we get.

[tex]2^{365}=7.52*10^{109}[/tex]

Which is basically 752 with 107 zeros following it.

Then we can divide this number by 100 to find the number of dollars it is.

We get 752 with 105 zeros following it.

Now we can find the arithmetic equation for the dollars.

We can see that 10 dollars is being added every time.

Use the formula.

[tex]a_n=a_1+m(n-1)[/tex]

We can plug in.

[tex]a_n=10+10(n-1)[/tex]

Now we can substitute 52 for [tex]x[/tex] in the equation.

[tex]a_{52}=10+10(52-1)[/tex]

[tex]a_{52}=10+510 \\ \\a_{52}=520[/tex]

So you'll be getting 520 dollars at the end of the year, which is far less than the amount of money you get from the pennies.
