Step-by-step explanation:

tan 0 = y/x (as a drawing attached)

The requried, y/x is equal to tan θ using coordinates on the unit circle. Option C is correct.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.

Here,
In a unit circle, the coordinates of a point on the circle are (cos θ, sin θ), where θ is the angle formed by the radius of the circle and the positive x-axis. Therefore, the tangent of θ is given by the ratio of sin θ to cos θ, which is (sin θ)/(cos θ) = y/x. Simplifying this expression, we get tan θ = y/x.

Therefore, the answer is option C) y/x.

Answer:;4.4

Step-by-step explanation: Since it varies inversely we know G times H squared is equal to some constant, k. So we have G*H*H=k. We are told that when H=4, G=.25. Plugging this in, we have .25*4*4=k. This simplifies to 4=k. Our new equation is G*H*H=4. Now, we want to solve for G when H=.3. We plug it in. G*.3*.3=4 => G*.09=4. G=4/.09. This means G is approximately 44.4.

Answer:

G = 44.44

Step-by-step explanation:

Given the mathematical expression and data;

[tex] G = \frac {1}{H^{2}} [/tex]

H = 4 and G = 0.25

First of all, we would determine the constant of proportionality, k.

[tex] G = \frac {k}{H^{2}} [/tex]

Making k the subject of formula, we have;

k = GH²

Substituting the values, we have;

k = 0.25 * 4²

k = 0.25 * 16

k = 4

Next, we find the value of G when H = 0.3;

[tex] G = \frac {k}{H^{2}} [/tex]

[tex] G = \frac {4}{0.3^{2}} [/tex]

[tex] G = \frac {4}{0.09} [/tex]

G = 44.44

Answer:

the x² test statistic 13.71

Option a) 13.71 is the correct answer.

Step-by-step explanation:

Given the data in the question;

Feeder                     1      2      3       4

Observed visits; [tex]o_i[/tex]  60   90   92    58

data sample = 300

Expected [tex]e_i[/tex] = 300 / 4 = 75

the x² test statistic = ?

[tex]X^2_{stat[/tex] = ∑[ ([tex]o_i[/tex] - [tex]e_i[/tex])²/[tex]e_i[/tex]]

[tex]X^2_{stat[/tex] = [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]

[tex]X^2_{stat[/tex] = [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]

[tex]X^2_{stat[/tex] = 13.7066 ≈ 13.71

Therefore, the x² test statistic 13.71

Option a) 13.71 is the correct answer.

Answer:

a) 6.09 %

b) 9.36 %

Step-by-step explanation:

a) Given  

% of questions that are truthful = 87% = -.87

% of right questions that are falsely indicated as lies = 7%

Percentage of the answers that the polygraph wrongly indicate as lies = 0.87 * 0.07 = 0.0609 = 0.1 = 10%

b) % of answers that are lies = 13% = 0.13

% of answers that are correctly caught as lies = 72%

percentage of the answers that the polygraph will correctly indicate as lies

= 0.13 * 0.72 = 0.0936 = 0.1 = 10 %

Answer:

552

Step-by-step explanation:

Area of a Triangle→S.A.S.

Area=1/2 ab sin C

area = 1/2 (64)(83) sin 168

area=552.213=552

If ΔNOP, o = 64 inches, p = 83 inches and ∠N=168°.Then area of ΔNOP is 552 square inch.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given,

ΔNOP, o = 64 inches, p = 83 inches and ∠N=168°.

The length of two sides and an angle is given.

So we can use SAS postulate

The SAS postulate says that if two sides of one triangle and the angle included between them are congruent to two sides and the included angle of a second triangle, then the triangles are congruent.

Area of a Triangle

Area=1/2 absin C

area = 1/2 (64)(83) sin 168

area =2656 sin 168

area=552.213=552

Hence area of ΔNOP, to the nearest square inch is 552 square inch

Answer:

Step-by-step explanation:

Step-by-step explanation:

Hey there!

The equation of a line which passes through the point (1,1) is (y-1) = m1 (x-1)...............(i) {using one point formula}

Also, another equation which is perpendicular to the line is y = 1/5 x + 4/5..........(ii)

Comparing equation (ii) with y= mx+c, we get;

Slope (m2) = 1/5.

Now, As per the condition of perpendicular lines,

m1*m2 = -1

or, m1 * 1/2 = -1

or, m1= -2

Therefore, m1 = -2.

Keeping the value of m1 in equation (i) we get;

y-1 = -2(x-1)

y-1 = -2x+1

or, y+2x-2= 0

Therefore, the required equation is 2x+y-2= 0.

Answer:

Step-by-step explanation:

take 23 degree as reference angle

using tan rule

tan 23=opposite/adjacent

0.42=x/3.2

3.2*0.42=x

1.34=x

1.3=x

Answer:

x equals to about 1.36

Step-by-step explanation:

Okay so first of all list write out Sin Cos and Tan. SOH-CAH-TOA

Now lets see what we are given. For the reference angle we are given 23.

We are also given 3.2 which is the adjacent angle. And the angle opposite of the reference angle is x. So all in all we have <23, Adjacent length 3.2, opposite length x.

Now we see which one would fit for this. That would be Tan since it deals with adjacent and opposite angles.

Now lets write it out as an equation. tan(23)= x/3.2 | Okay now next to get x alone we move it to the right side. That would leave us with tan(23)*3.2 which equals to about 1.36 "1.35831941187". Remember to use degree and not radiant.

Answer:

The probability would be 3/25

The correct answer is vertex of the graph D. (0, 2).

To find the vertex of the graph of the function y = |x| + 2, we need to determine the point where the function reaches its minimum or maximum value.The graph of y = |x| is a V-shaped graph with the vertex at the origin (0, 0). When we add 2 to this function, the graph is shifted upward by 2 units.So, the vertex of the graph of y = |x| + 2 is at (0, 2).

Therefore, the correct answer is D. (0, 2).The function y = |x| + 2 represents a V-shaped graph, and the vertex of this graph occurs at the origin (0, 0). By adding 2 to the function, the graph is shifted upward by 2 units. Therefore, the vertex of the modified function y = |x| + 2 is found by shifting the original vertex (0, 0) vertically by 2 units. This means the new vertex is located at (0, 2). This point represents the minimum value of the function, as it is the lowest point on the graph.
