Answer:A

Step-by-step explanation:

Answer:

13

Step-by-step explanation:

since the inside of a triangle is equal to 180

180-42-73=65

65/5=13 so 13 should be the answer.

Sum of the interior angles of a triangle= 180°

Therefore, 42°+ 73°+5a= 180°

=> 115°+5a = 180°

=> 5a= 180- 115°

=> 5a = 65°

=> a = 65°/5

=> a= 13°

OPTION D

Answer:

6.2%, option A.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

The desired area to hit is of 50 in², while the total area is of 804 in². Thus, the probability of hitting the bull's-eye is:

[tex]p = \frac{50}{804} = 0.062[/tex]

0.062*100% = 6.2%.

6.2%, option A.

Here is the Matlab code.

Step-by-step explanation:

Matlab Code:

[tex]A = [1 2 2;3 4 5;6 7 8]\\[U,S,V] = svd(A)u1 = U(:,1)\\u2 = U(:,2)\\u3 = U(:,3)\\d1 = dot(u1,u2)\\c = cross(u1,u2)\\d2 = dot(c,u3)[/tex]

[tex]d1 =- 5.5511e-17\\c = -0.7172 0.6643 -0.2103\\d2 = 1[/tex]  

Yes, since c = cross(u1,u2) is orthogonal to both u1 and u2. Hence is u3, thus the dot product with u3 is 1.

Answer:

0.2051

Step-by-step explanation:

The probability of follppping a coin 10 tones and getting a tail 6 times can be solved in different ways :

One way is to use the binomial probability relation :

Where :

P(x = x) = nCx * p^x * q^(n-x)

Number of trials, n = 10

p = 1/2 (probability of obtaining a tail per flip)

q = 1- 1/2 = 1/2

x = 6

P(x = 6) = 10C6 * 0.5^6 * 0.5^4

P(x = 6) = 0.205078125

P(x = 6) = 0.2051

Step-by-step explanation:

Her starting point is negative since it is below the entrance

-42

Descends 12 feet so subtract 12

-42 -12 = -54

Ascends 18 ft so go up 18 which means add 18

-54 +18 =-36

Answer:

The opponent won 2 sets in 4 matches, 1 set in 4 matches, and 0 sets in 2 matches.

Step-by-step explanation:

Given that in the last week, Daniela has played 10 tennis matches, and she remembers that her opponent had won 1 set in 4 of the matches and her opponent was expected to win a total of 6 sets over the course of 5 matches, but she Can't remember how many times her opponent won 0 or 2 sets, knowing that in total he played 10 games, to determine the number of times his opponent obtained these results, the following calculation must be performed:

5 matches = 6 sets

10 matches = 12 sets

10 - 4 = 6

12 - 4 = 8

8/2 = 4

Therefore, the opponent won 2 sets in 4 matches, 1 set in 4 matches, and 0 sets in 2 matches.

The graph equation

From the graph, we have:

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (1,1)[/tex]

The slope of the graph is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{1-0}{1-0}[/tex]

[tex]m = \frac{1}{1}[/tex]

[tex]m =1[/tex]

So, the graph equation is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 1 * (x - 0) + 0[/tex]

[tex]y = 1 * x[/tex]

[tex]y = x[/tex]

In standard form, we have:

[tex]x - y = 0[/tex]

Answer:

  1731 ft

Step-by-step explanation:

The tangent relation is useful in this problem.

  Tan = Opposite/Adjacent

The height of the light is found to be ...

  tan(11°) = height/(639 ft)

  height = (639 ft)·tan(11°) . . . . . solve for height

Then the distance from the light to point B is ...

  tan(3°) = height/(B distance)

  B distance = height/tan(3°) = (639 ft)·tan(11°)/tan(3°) ≈ 2370 ft

Then the distance from point A to point B is ...

  2370 ft -639 ft = 1731 ft . . . AB distance

Tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The distance between points A and B is 1731 feet.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm{Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

As it is given that the distance between the lighthouse and point A is 639 feet, while the angle of elevation from that point is 11°. therefore, using the tan function, the height of the lighthouse,

[tex]\rm Tan(\theta) = \dfrac{Perpendicular}{Base}\\\\Tan(11^o) = \dfrac{CD}{CA}\\\\Tan(11^o) = \dfrac{CD}{639}\\\\Tan(11^o) \times 639 = CD\\\\[/tex]

As we know that CD is the height of the lighthouse, now

In Δ BCD

The tan function for the distance between the lighthouse and point B can be written as,

[tex]\rm Tan(\theta) = \dfrac{Perpendicular}{Base}\\\\Tan(3^o) = \dfrac{CD}{CA}\\\\Tan(3^o) = \dfrac{Tan(11^o) \times 639}{CA}\\\\CA = 2370\ ft.[/tex]

Hence, the distance between the lighthouse and Point B is 2370 ft.

Now, we know the distance between the lighthouse and Point A, and the distance between the lighthouse and Point B, therefore,

The Distance between Point A and B (AB) = CB - CA

                                                                       = 2370 - 639

                                                                       = 1731 ft.

Answer:

x = 44.3°

Step-by-step explanation:

Redrawing the triangle,

To obtain x, we can apply the trigonometric relation :

Sin x = opposite / hypotenus

Opposite side = 6.5

Hypotenus = 9.3

Sin x = 6.5/9.3

x = sin^-1(6.5 / 9.3)

x = 44.34

x = sqrroot(5)

Step-by-step explanation:

The radical form of x²=5 is x= ±√5.

The √ symbol that is used to denote square root or nth roots.

An expression with a square root is referred to as a radical expression. Radicand: A value or phrase included within the radical symbol.

Radical notation is the usage of a root in an expression, such as the square or cube root.

For example,  radical form is ∛3 = √27.

Given:

x²=5

Now, we have to write it in the radical form.

So, we can write

x= ±√5

Hence, the radical form of x²=5 is x= ±√5.

Answer:

  multiply the radius by √1.2 ≈ 1.0954

Step-by-step explanation:

Let the original depth and radius be represented by 30 and r. Let the modified depth and radius be represented by 25 and r'. Assuming the pond is uniform depth, the formula for the volume of a cylinder applies. The volume of a cylinder is given by ...

  V = πr²h

In this application, we want the original and modified volumes to be the same.

  πr²(30) = π(r')²(25)

  (r')² = r²(30/25) = r²(6/5)

  r' = r√(6/5)

The radius can be multiplied by √1.2 to maintain the original volume of the pond.
