evaluate cot (\pi )/(7)

Answer:

46 ft

Step-by-step explanation:

A = (pi)r^2

(pi)r^2 = 1661.06 ft^2

r^2 = 529 ft^2

r = 23 ft

d = 2r = 2(23) = 46 ft

Answer: 46 ft

Answer:

20%/100×73.28=14.65

Step-by-step explanation:

to answer this you have to find out what 20% of 73.28 is by dividing 20% by 100 then multiplying by 73.28

Answer:

Your answer would be the third one

Step-by-step explanation:

Triangle 1 - 73, 45

Triangle 2 - 47, 30

Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.

Option (4) is correct.

A triangle in geometry is a three-sided polygon with three edges and three vertices.

As per the given data:

We are given two angles for each pair of triangles, and we have to find out which of the pair of triangles are similar.

For any two triangles to be similar, it must have 2 angles which are having the same measure.

For, Triangle 1: 55°, 45° and Triangle 2: 55°, 80°

Only one angle is same, hence not similar.

Triangle 1: 103°, 32° and Triangle 2: 103°, 25°

Only one angle is same, hence not similar.

Triangle 1: 73°, 47° and Triangle 2: 47°, 30°

Only one angle is same, hence not similar.

Triangle 1: 105°, 23° and Triangle 2: 52°, 105

By using angle sum property in Triangle 1 the remaining angles is:

= 180 - (105 + 23) = 52°

By using angle sum property in Triangle 2 the remaining angles is:

= 180 - (52 + 105) = 23°

2 angles are same, hence similar.

Triangle 1: 99, 41° and Triangle 2: 40°, 99°

Only one angle is same, hence not similar.

Hence, Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.

Answer:

2/3

Step-by-step explanation:

Prime numbers are 2,3, and 5 on the six-sided die. Also including the number 1, the probability of rolling one of these numbers is 4/6 or 2/3 simplified.

Answer:

the Option you declared as B

Answer:

$2250

Step-by-step explanation:

selling the ring at 100% of $1500 would equal 1500 and yield no profit

therefore, you must sell the ring at 150% (where 100% covers the cost and the additional 50% provides the profit) of 1500

1.5 x 1500 = 2250

Answer:

Step-by-step explanation:

This is one of those questions that  has no answer. The first one is not a triangle. 3 and 6 = 9. Two of the legs have to longer than the third. 9 is not greater than 10.

So there is no answer. However leave a note of there is a mistake in what you wrote and I'll come back.

The other two are right (the middle one) and the last one is acute.

Answers:

============================================================

Explanation:

The y intercept of the black f(x) curve is at (0,1)

The y intercept of the blue curve is at (0,4)

To go from y = 1 to y = 4, we add 3

So we shift 3 units up to go from the f(x) curve to the g(x) curve.

The value of k is 3, which corresponds exactly to the vertical shift. If we shifted down, then k would be negative.

Answer:

Rs. 45,150

Step-by-step explanation:

Given data

Cost =Rs. 35000

Profit=16%

VAT=13%

Let us find the profit to be added

=16/100*35000

=0.16*35000

=Rs. 5,600

Let us find the VAT to be added

=13/100*35000

=0.13*35000

=Rs. 4,550

Hence the cost of the bike is

=4,550+ 5,600+ 35000

=Rs. 45,150

Answer:

5.218

Step-by-step explanation:

-Chetan K

Answer:

- 75 and - 28

Step-by-step explanation:

To evaluate f(6) substitute x = 6 into f(x)

f(6) = - 2(6)² - 3 = - 2(36) - 3 = - 72 - 3 = - 75

Similarly

g(5) = - 5(5) - 3 = - 25 - 3 = - 28

Answer:

y = 2x - 3

Step-by-step explanation:

Take any two points from the graph

(0,-3)   & (2 ,1)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

         [tex]= \frac{1-[-3]}{2-0}\\\\= \frac{1+3}{2}\\\\= \frac{4}{2}\\\\= 2[/tex]

m = 2

[tex]y - y_{1}=m(x -x_{1})\\\\y - [-3] = 2(x - 0)\\\\y + 3 = 2x\\\\y = 2x - 3[/tex]

D, solved it graphically

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

[tex]Total=h+(h-2)[/tex]

[tex]Total=2h-2[/tex]

It is given that the total number of visitors is 80. So,

[tex]2h-2=80[/tex]

[tex]2h=80+2[/tex]

[tex]2h=82[/tex]

Divide both sides by 2.

[tex]h=\dfrac{82}{2}[/tex]

[tex]h=41[/tex]

Therefore, the correct option is D.

Answer:

Below in bold.

Step-by-step explanation:

We have a right triangle here with the hypotenuse = 2 and the legs are 1 and √3.

If tan A > 0 then the opposite side to < A  in the triangle is greater than the adjacent so the leg opposite angle A is √3 and the adjacent side = 1.

So cos A = adj/hyp = 1/2.

Answer:

1.2 times or 20%

Step-by-step explanation:

Given the function ; f(x) = 830(1.2)^x

This is an exponential function ;

Recall the general form of an exponential function ; f(x) = ab^x ;

Where a = Initial value ; b = growth rate

Hence, b = 1.2

Also, b = 1 + r

1.2 = 1 + r

r = 1.2 - 1

r = 0.2

r = 0.2 * 100% = 20%
