please help me im stuck on this question​

Answer:

A and D

Step-by-step explanation:

Unit circle is a circle described by the equation

x^2 + y^2 = 1

We can try each pair and check

A. [tex](\frac{6}{7})^2 + (\frac{\sqrt{13}}{7})^2 = \frac{36}{49} + \frac{13}{49} = \frac{49}{49} = 1[/tex]

B. [tex](\frac{4}{3})^2 + (\frac{4}{5})^2 > (\frac{4}{3})^2 > 1[/tex]

C. [tex](\frac{1}{3})^2 + (\frac{2}{3})^2 = \frac{1}{9} + \frac{4}{9} = \frac{5}{9} < 1[/tex]

D. [tex](\frac{5}{13})^2 + (\frac{12}{13})^2 = \frac{25}{169} + \frac{144}{169} = \frac{169}{169} = 1[/tex]

The statement first “The intersection of two planes is a line." option (a) is correct.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

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

We have two planes, Y and Z intersecting each other.

The intersection of two lines is a point.

As we know, if the two planes intersect each other, the intersection will be a line.

If planes are parallel then there will no intersection.

Thus, the statement first “The intersection of two planes is a line." option (a) is correct.

Answer:

  86.7

Step-by-step explanation:

The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(64°) = 38/x

  x = 38/cos(64°) ≈ 86.685

The value of x is about 86.7.

Answer:

Rule : x subtracted by 12 = y , first ? = 6 (6,-6) , second ? = -22 (-10,-22)

Answer:

D

Step-by-step explanation:

I know the answer is D because I set the equation to be equal to x.

First, I added c to both sides. The equation looked like: 7x=k+c

Then, I divided 7 on both sides, so x would be by itself. The equation looked like x=k+c/7

In conclusion, the answer is D. x=k+c/7

Step-by-step explanation:

Answer:

The answer is "0.9184".

Step-by-step explanation:

This problem is assisted by data analysis:

Its overview hypothesis test to two sample proportions:

[tex]p_1 :[/tex]percentage of population contributions 1

[tex]p_2:[/tex]percentage of population contributions 2

[tex]\to p_1 - p_2:[/tex] proportion difference

[tex]\to H_0 : p_1 - p_2 = 0\\\\\to H_A : p_1 - p_2 ? 0[/tex]

Calculating the Hypothesis test values:

[tex]Diff \ \ Count1 \ \ Total1 \ \ Count2 \ \ Total2 \ \ Sam. Diff. \ \ Std. Err.\ \ Z-Stat \ \ P value\\\\[/tex]

[tex]p_1 - p_2\ \ 10\ \ 108\ \ 20\ \ 208\ \ -0.0035612536\ \ 0.034766147\ \ -0.10243452 \ \ 0.9184[/tex]

So, the [tex]P - value = 0.9184[/tex]

Answer: g

Step-by-step explanation:

Answer:

t=11.9

Step-by-step explanation:

960=420(2)^t/10

2.28571429=2^t/10

add log to both sides

log(2.28571429)=10 t  log(2)

divide by log 2

1.19264508=  10 /t

10(1.19264508)

11.926450779=t

Answer:

X+2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Both of the graphs include infinite number of points.

The solution is the common point that belongs to both of the graphs, their intersection, which is the point (1, 5)

This is the point when the temperature change is positive 1 degree.  At this point number of visitors is equal to number of those leaving the part early (5 visitors).

Answer:

(1,5)

Step-by-step explanation:

The graphs intersect at (1,5). At this point, the temperature change is 1 degree and the number of visitors is equal to those leaving early, which is 5 visitors.

Answer:

Step-by-step explanation:

Given that:

the differential equations:

[tex]\dfrac{dx}{dt}= x+y = 1 \\ \\ \dfrac{dy}{dt}= 1-x^2+y^2[/tex]

For x-nullcline;

[tex]\implies \dfrac{dx}{dt} =0 \\ \\ \implies x+y-1[/tex]

From the image attached below, the sketch of the x-nullcline was carefully drawn and the regions were identified.

So, x-increases at the time when [tex]\dfrac{dx}{dt}>0[/tex]

[tex]\implies x+y -1 >0[/tex]

Thus, the solution move towards the right for  x+y>1

Answer:

angle AGF = 55

Step-by-step explanation:

Assumed that this would be a perpendicular because of the 90 degree mark. So did 90 - 35 = 55

Answer:

28.5

Step-by-step explanation:

The sum of the interior angles in a triangle is equal to 180

102 + x + 6 + x + 15 = 180

123 + 2x = 180 subtract 123 from both sides

2x = 57 divide both sides by 2

x = 28.5

Answer:

48 yd²

Step-by-step explanation:

The shaded region is a trapezoid

Area of shaded region = area of the trapezoid

Area of trapezoid = ½(a + b)h

a = 6 yd

b = 10 yd

h = 15 - 9 = 6 yd

Area of trapezoid = ½(6 + 10)6

= ½(16)6

= 48 yd²

Area of the shaded region = 48 yd²
