Answer:

[tex]circumference = 2 \pi r = 2 \times 3.14 \ times 1 = 6.28m\\\\Area = \pi r^2 = 3.14 \times 1 \times 1 = 3.14m^2[/tex]

The circumference of the circle is, 6.28 meter.

And, The area of circle is, 3.14 meters²

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

A circle with radius of 1 meter.

Now, We know that;

The circumference of the circle = 2πr

Hence, We get;

The circumference of the circle is,

⇒ 2 × 3.14 × 1

⇒ 6.28 meter

And, The area of circle is,

⇒ Area = πr²

⇒ Area = 3.14 × 1²

⇒ Area = 3.14 meters²

Thus, The circumference of the circle is, 6.28 meter.

And, The area of circle is, 3.14 meters²

Answer:

∠ EDC = 55°

Step-by-step explanation:

Since Δ ADE is isosceles then the 2 base angles are congruent , then

∠ EDA = [tex]\frac{180-20}{2}[/tex] = [tex]\frac{160}{2}[/tex] = 80°

Similarly for Δ BCD

∠ CDB = [tex]\frac{180-90}{2}[/tex] = [tex]\frac{90}{2}[/tex] = 45°

The 3 angles on AB sum to 180° , that is

80° + ∠ EDC + 45° = 180°

∠ EDC + 125° = 180° ( subtract 125° from both sides )

∠ EDC = 55°

Answer:

c=21.6

Step-by-step explanation:

First, find the last angle of the triangle.

The sum of all the angles in a triangle is 180 degrees.

A+90+37=180

A=53

Now find x

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(B)=adj/hyp

rewrite as

c=a/cos(B)

c=17.3/cos(37)

c=21.66194688

Answer:

Answer: $9,500

Step-by-step explanation:

If the value of the car depreciates by 5% in a year it means that the value of the car reduced by 5%.

First find the 5%:

= 5% * 10,000

= $500

Subtract this from the initial value to find the value after a year:

= 10,000 - 500

= $9,500

Answer:

$ 9500

Step-by-step explanation:

From the question given above, the following data were obtained:

Initial value = $ 10000

Depreciation rate = 5%

Value after one year =?

Next, we shall determine the depreciation value. This can be obtained as follow:

Initial value = $ 10000

Depreciation rate = 5%

Depreciation value =?

Depreciation value = Initial value × rate

Depreciation value = 10000 × 5%

Depreciation value = 10000 × 5/100

Depreciation value = $ 500

Finally, we shall determine the value of the car after one year. This can be obtained as follow:

Initial value = $ 10000

Depreciation value = $ 500

Value after one year =?

Value after one year = Initial value – Depreciation value

Value after one year = 10000 – 500

Value after one year = $ 9500

Therefore, the value of the car after one year is $ 9500

The solution to the quadratic equation x² - 4x + 1 = 0 is x = ( 4 ±√12 ) / 2

A quadratic equation in its standard form is expressed as;

ax² + bx + c = 0

Where x is the unknown

To solve for x, we use the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

Given the quadratic equation in the question;

x² - 4x + 1 = 0

We substitute this values into the quadratic formula above and solve for x.

x = (-b±√(b² - 4ac)) / (2a)

x = ( -(-4) ±√( (-4)² - ( 4 × 1 × 1)) / (2 × 1)

x = ( 4 ±√( 16 - 4) ) / (2)

x = ( 4 ±√12 ) / 2

Therefore, ( 4 ±√12 ) / 2 is the solution to the equation.

Option C) ( 4 ±√12 ) / 2 is the correct answer.

Imagine cutting up a pizza into 5 slices

If you take 2 slices, then you take 2 out of the 5, so the fractional amount you took is 2/5 of the full pizza.

If your friend takes 3 slices, then she or he takes 3/5 of the full pizza

Adding the two fractional amounts should get us back to 1 full pizza, which is why 2/5+3/5 = 1.

-----------

We could say this:

2/5 + 3/5 = (2+3)/5 = 5/5 = 1

Dividing any number over itself, as long it's not zero, always leads to 1.

So that's why 5/5 = 1.

Answer:

101

Step-by-step explanation:

According to the Law of Cosines, for any △ABC with side lengths a, b, and c, a2=b2+c2−2bccosA; b2=a2+c2−2accosB; and c2=a2+b2−2abcosC

.

The Law of Cosines can be used because all three side lentghs are known.

Set up the equation for the Law of Cosines:

a2=b2+c2−2bccosA

Substitute the known values into the Law of Cosines:

312=222+182−2(22)(18)cosA

Square the values and multiply:

961=484+324−792cosA

Add:

961=808−792cosA

Subtract 808

from both sides:

153=−792cosA

Divide both sides by −792

:

153−792=cosA

According to this equation m∠A

is equal to the inverse cosine function of −153792

. Write this:

m∠A=cos−1(−153792)

Calculate the value of the inverse cosine −153792

m∠A≈101°

B. He used the wrong expression to represent the area of the base of the pyramid.

Step-by-step explanation:

Given

See attachment for pyramid

[tex]Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4[/tex]

Required

Vikram's error

The surface area of a square pyramid is:

[tex]Area = Base\ Area + 4 * Area \triangle[/tex]

Where

[tex]Base\ Area = Length * Length[/tex]

[tex]Base\ Area = 34.2 * 34.2[/tex]

[tex]4 * Area \triangle = 4 * \frac{1}{2} * Base * Height[/tex]

[tex]4 * Area \triangle = 4 * \frac{1}{2} * 34.2 * 28.4[/tex]

So:

[tex]Area = Base\ Area + 4 * Area \triangle[/tex]

[tex]Area = 34.2 * 34.2 + 4 * \frac{1}{2} * 34.2 * 28.4[/tex]

The coordinate of the rest stop is: [tex](5,2.5)[/tex]

The distance between the hotel and the stadium is 32 miles

Step-by-step explanation:

Given

[tex](x_1,y_1) = (3,4)[/tex] --- Team hotel

[tex](x_2,y_2) = (7,1)[/tex] --- Stadium

Solving (a): The coordinates of the rest stop

The rest stop is at half way;

So, the coordinate is:

[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

This gives:

[tex](x,y) = \frac{1}{2}(3+7,4+1)[/tex]

[tex](x,y) = \frac{1}{2}(10,5)[/tex]

Open bracket

[tex](x,y) = (5,2.5)[/tex]

Solving (b): Distance between the hotel and the stadium

We have:

[tex](x_1,y_1) = (3,4)[/tex] --- Team hotel

[tex](x_2,y_2) = (7,1)[/tex] --- Stadium

The distance (d) is:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

So, we have:

[tex]d = \sqrt{(3 - 7)^2 + (4 - 1)^2}[/tex]

[tex]d = \sqrt{(-4)^2 + 3^2}[/tex]

[tex]d = \sqrt{16 + 9}[/tex]

[tex]d = \sqrt{25}[/tex]

[tex]d =5[/tex]

From the question, we have:

[tex]1\ unit = 6.4\ miles[/tex]

So:

[tex]d =5 * 6.4\ miles[/tex]

Answer:

The measure of Angle G is 41

Step-by-step explanation:

We know that in a parallelogram, opposite angles are congruent, therefore let's solve for x-value first;

3x + 11 = 5x - 9

11 = 5x - 3x - 9

11 = 2x - 9

11 + 9 = 2x

20 = 2x

20/2 = x

10 = x

Now that we have x-value, we can substitute it in the equation for Angle G to find it's angle measure;

5(10) - 9 = ∠G

50 - 9 = ∠G

41 = ∠G

So the final answer = The measure of Angle G is 41
