The circumference of the circle is 10π cm, and the area is 25π cm².

The formulas for the circumference (C) and area (A) of a circle in terms of

the radius (r) are:

Circumference (C) = 2πr

Area (A) = πr²

Given that the radius (r) is 5 cm, we can substitute this value into the formulas:

Circumference (C) = 2π(5) = 10π cm

Area (A) = π(5)² = 25π cm²

So, the circumference of the circle is 10π cm, and the area is 25π cm².

472 adult tickets and 868 student tickets were sold.

Step-by-step explanation:

Let x be the number of adult tickets sold.

Let y be the number of student tickets sold.

Your Equations:

x + y = 1340 tickets

5x + (1)y = $3228

Isolate the y variable:

y = 1340 - x

y = 3228 - 5x

Substitute:

1340 - x = 3228 - 5x

Solve:

1340 - x = 3228 - 5x

Add 5x on both sides

1340 + 4x = 3228

Subtract 1340 on both sides

4x = 1888

Divide 4 on both sides

x = 472

Plug in x into an equation:

472 + y = 1340

Subtract 472 on both sides

y = 868

472 adult tickets were sold

868 student tickets were sold.

1875 cm>3 i think

Step-by-step explanation:

The new model {A} for the total number of new green tea and fruit juice sales can be written as {A} = 1574 + 3t - 2t².

Given is that during a 20-year period, G and I can be modeled by the following equation (where t is the time in years) :

G = 674 + 3t – 2t² + 5t + 60

I = 314 - 31 + 512 - 5t + 45

where {G} is the number (in billions) of new green tea sales and {I} be the number in billions of new fruit juice sales.

A new model {A} for the total number of new green tea and fruit juice sales can be written as -

{A} = {G} + {I}

{A} = 674 + 3t – 2t² + 5t + 60 + 314 - 31 + 512 - 5t + 45

{A} = (674 + 60 + 314 - 31 + 512 + 45) + (3t + 5t - 5t) - 2t²

{A} = 1574 + 3t - 2t²

Therefore, the new model {A} for the total number of new green tea and fruit juice sales can be written as {A} = 1574 + 3t - 2t².

Final answer:

To create a new model for the total sales of green tea and fruit juice, the sales equations for both products are added together and simplified, resulting in the model A = 3t² + 1093, representing combined sales in billions as a function of time in years.

Explanation:

To find a new model A for the total number of new green tea and fruit juice sales, we need to combine the models given for G (green tea sales) and J (fruit juice sales). The models provided had some errors, but they should be:

G = 674 + 3t – 2t² + 5t + 60

and

J = 314 – 3t + 5t² – 5t + 45

Combining these models to form A (total sales), we add G and J together:

A = G + J

= (674 + 3t – 2t² + 5t + 60) + (314 – 3t + 5t² – 5t + 45)

Now, we simplify the equation by combining like terms:

A = (674 + 314) + (3t – 3t) + (5t – 5t) – 2t² + 5t² + (60 + 45)

A = 988 + 0t + 0t + 3t² + 105

A = 988 + 3t² + 105

A = 3t² + 1093

Therefore, the new model A for the total sales is A = 3t² + 1093. This model represents the combined sales of green tea and fruit juice in billions of dollars during the 20-year period as a function of time t in years.

Answer:

Cliff is 45 m tall.

Step-by-step explanation:

Given:

Height of Sarah = 1.8 m

Angle of elevation = 60°

Angle of elevation 50 m back = 30°

As shown in the figure we have two right angled triangles SPQ and SPR.

Let the height of the cliff be [tex]h[/tex] meters and [tex]h= h_1+h_s[/tex].

Using trigonometric ratios:

tan (Ф) = opposite/adjacent

In ΔSPQ.                                        In ΔSPR.

⇒ [tex]tan(60) = \frac{h_1}{x}[/tex] ...equation (i)        ⇒ [tex]tan (30)=\frac{h_1}{x+50}[/tex]  ...equation (ii)

Dividing equation (i) and (ii)

⇒ [tex]\frac{tan(60)}{tan(30)} = \frac{h_1}{x} \times \frac{x+50}{h_1}[/tex]

⇒ [tex]3 = \frac{x+50}{x}[/tex]

⇒ [tex]3x=x+50[/tex]

⇒ [tex]3x-x=50[/tex]

⇒ [tex]2x=50[/tex]

⇒ [tex]x=\frac{50}{2}[/tex]

⇒ [tex]x=25[/tex] meters

To find [tex]h_1[/tex] plugging [tex]x=25[/tex] in equation (i)

⇒ [tex]h_1=x\times tan(60)[/tex]

⇒ [tex]h_1=25\times 1.73[/tex]

⇒ [tex]h_1=43.25[/tex] meters

The height of the cliff from ground :

⇒ [tex]h= h_1+h_s[/tex]

⇒ [tex]h= 43.25+1.8[/tex]

⇒ [tex]h=45.05[/tex] meters

The cliff is 45 m tall to the nearest meter.

The value of the laptop in 2011 will be $29920

Step-by-step explanation:

Cost of the laptop = $34000

Rate of decrease in value per year = 4%

Total time = 3 years

The Value decrease in 2011 = (34000 x 4 x 3) /100

= $4080

The value of the laptop in 2011 = 34000-4080

= $29920

The value of the laptop in 2011 will be $29920

Step-by-step explanation:

You can use the Pythagorean Theorem to find missing lengths in objects that are right triangles.

The Pythagorean Theorem is a mathematical principle that relates to right triangles. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

You can use the Pythagorean Theorem to find missing lengths in objects that are right triangles.

The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

By rearranging the formula, you can solve for the missing length when given the lengths of the other two sides.

This can be applied to real-world problems involving measurements of objects or distances, such as determining the length of a ladder needed to reach a certain height on a wall or calculating the distance between two points on a map.

Comment on units conversion

I find it convenient to work units conversion problems by writing a fraction that is equal to 1 and multiplying by that to change units. My fraction has the "to" units in the numerator, and the "from" units in the denominator. That way, the unwanted units cancel when the multiplication is carried out.

The fraction is equal to 1 because the measurement in the numerator is equal to the measurement in the denominator.

__

Some folks prefer proportions. If you do it that way, be sure "like" is matched with "like".

For the first parametric functions the cartisian function is y = 5+ 0.84x - 0.7x², and for the second parametric function the cartisian function is y = 2/x where x>0

A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.

For the first parametric functions:

[tex]\rm x(t)=23t \\\\y(t)=5+19.3t-16t^2[/tex]

[tex]\rm t = \dfrac{x}{23}[/tex]

Put this value in the y(t)

[tex]\rm y=5+19.3(\dfrac{x}{23})-16(\dfrac{x}{23})^2[/tex]

y = 5+ 0.84x - 0.7x²

For the second parametric functions

[tex]\rm x(t)=e^t .....(1)\\\\y(t)=2e^-^t[/tex]

Taking ln in equation (1)

lnx = t

Put this value in equation (2)

[tex]\rm y=2e^{-lnx}[/tex]

y = 2/x,   x>0

Step-by-step explanation:

Final answer:

To find the measure of angle 2, which is complementary to angle 1 with a measure of 56°, subtract 56° from 90°, resulting in angle 2 measuring 34°.

Explanation:

If angles 1 and 2 are complementary, it means that the sum of their measures is 90 degrees. Since the measure of ∠1 is given as 56°, we can find the measure of ∠2 by subtracting the measure of ∠1 from 90 degrees:

Measure of ∠2 = 90° - Measure of ∠1

Measure of ∠2 = 90° - 56°

Measure of ∠2 = 34°

Therefore, the measure of ∠2 is 34 degrees.

By using the similar triangles principle, the height of the building is found to be 132 meters. We find this by setting up a proportion between the known ratios of the pole's height to its shadow and solving for the building's height.

We can solve the problem using similar triangles. The ratio of the height of the pole to its shadow is the same as the ratio of the height of the building to its shadow. Since the height of the pole is 6m and its shadow is 10m, we have the ratio of the height to the shadow for the pole as 6/10 or 3/5.

This ratio will be equal to the ratio of the height of the building (which we'll call h) to the shadow of the building (220 m), so we can write the proportion as:

3/5 = h/220

Now we solve for h:

3/220 = h/5

h = (3/5) × 220

h = (3 × 44)

h = 132m

So the height of the building is 132m.
