Answer:

the distance of the Bird (B) from the plane (P)  is = 10779  ft

Step-by-step explanation:

From the given information:

a diagrammatic representation is attached below for better understanding and solution to the question.

From the diagram;

Let the Bird (B) be represent as A

The plane (P) be represented by B

The observer be represented by O

and the tower T be represented by C

we will see that:

[tex]\overline {AB} \ \| \ \overline {OC}[/tex]

Also;

[tex]\angle ABO = \angle BOC = 33^0[/tex]

AO = BC = 7000

Let consider the trigonometry of  triangle BAO

tan θ = opposite/adjacent

tan 33° = 7000/x

0.6494 = 7000/x

x = 7000/0.6494

x = 10779.18

x = 10779  ft    ( to the nearest whole number)

Thus; the distance of the Bird (B) from the plane (P)  is = 10779  ft

Answer: 10,779 feet

Answer:

cos(α2)= −1/5√2

Step-by-step explanation:

you are given  tan(α)=7/24 , so you can find the length of the hypotenuse using the Pythagorean theorem, which is  a2+b2=c2  with  a  and  b  being the legs of the triangle and  c  being the hypotenuse of the triangle.

c2=7^2+24^2  

⟹c2=49+576

⟹c2=625

⟹c=25

if  π<α<3π/2  , then  α  has to lie in quadrant III where cosine is negative. so cos(α)= −24/25

The half-angle identity for the cosine function is  cos(α2)=±√1+cos(α)/2  , so plugging the information in, we get

cos(α2)=±√  1+(−24/25)/2

⟹ cos(α2)=±√1/25 / 2

⟹cos(α2)=±√1/50

⟹cos(α2)=±1/5√2

Answer:

3 multiplied by 10^-10

Answer:  y = 3x + 1

Step-by-step explanation:

In the equation y=mx+b (slope - intercept form), m represents the slope and b represents the y - intercept of the equation. We can use this to answer the problem.

Because the problem specifies here that the equation we are trying to solve for is parallel to y= 3x - 5, we can assume that its slope is 3 (the same as the line it is parallel to - this is so because of the definition of parallel lines).

m = 3

And finally, we know that the y-intercept will be in the form (0, b) - which is exactly what the given point is in. Substitute the value in, and we get:

b = 1

Now put these two values into one equation.

y = mx + b

y = (3)x + (1)

y = 3x + 1

Answer:

10 nickels and 10 quarters

Step-by-step explanation:

Given

Number of coins: 20

Vaiue of coins = $3.00

Required

Number of Nickels and Quarters;

Let N =Nickels and Q =Quarters

The total coins is represented as:

[tex]N + Q = 20[/tex]

1 nickel is equivalent to $0.05 and 1 quarter is equivalent to $0.25; So

[tex]0.05N + 0.25Q = 3[/tex]

Make N the subject of formula in the first equation

[tex]N = 20 - Q[/tex]

Substitute this in the second equation

[tex]0.05(20 - Q) + 0.25Q = 3[/tex]

[tex]1 - 0.05Q + 0.25Q = 3[/tex]

Collect like terms

[tex]-0.05Q + 0.25Q = 3 - 1[/tex]

[tex]0.2Q = 2[/tex]

Multiply both sides by 5

[tex]5 * 0.2Q = 2 * 5[/tex]

[tex]Q = 10[/tex]

Recall that N = 20 - Q

[tex]N = 20 - 10[/tex]

[tex]N = 10[/tex]

The simplified form of an algebraic expression is x+9.

The given algebraic expression is x-5/5+10.

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and algebraic operations.

Now, x-5/5+10=x-1+10

=x+9

Therefore, the simplified form of an algebraic expression is x+9.

Answer:

The the equation of the line through the points (8, -2) and (5, 5) in slope-intercept form is

[tex]y=-\frac{7}{3} x+\frac{50}{3}[/tex]

Step-by-step explanation:

Let's start by calculation the slope of the line by finding the slope of the segment that joins the two given points (8, -2) and (5,  5):

[tex]slope=\frac{y_2-y_1}{x_2-x_1} \\slope=\frac{5-(-2)}{5-8}\\slope=\frac{7}{-3} \\slope=-\frac{7}{3}[/tex]

Now we use this slope in the general slope-intercept form of a line;

[tex]y=mx+b\\y=-\frac{7}{3} x+b[/tex]

and then we calculate the value of the intercept "b" by using one of the given points through which the line must pass (for example (5,5) ), and solving for b:

[tex]y=-\frac{7}{3} x+b\\5=-\frac{7}{3} (5)+b\\5=-\frac{35}{3} +b\\b=5+\frac{35}{3}\\b=\frac{50}{3}[/tex]

The the equation of the line is

[tex]y=-\frac{7}{3} x+\frac{50}{3}[/tex]

Answer:

11  1 /2

Step-by-step explanation:

Answer:

A random movie is between 1.8 and 2.0 hours.

z=1.8-1.9/0.3= -0.33= 0.3707

z=2.0-1.9/0.3= 0.33= 0.6293

0.6293-0.3707= 0.2586

Therefore, the chance a random movie is between 1.8 and 2.0 hours long is 0.2586.

A movie is longer than 2.3 hours.

z=2.3-1.9/0.3 =1.33 =0.9082

1-0.9082= 0.0918

Therefore, the chance a movie is longer than 2.3 hours is 0.9082.

The length of movie that is shorter than 94% of the movies

z=x-1.9/0.3= 0.94

z=x-1.9/0.3= 1-0.94= 0.06

=x-1.9/0.3= 0.06= -1.56

x= 1.432

Therefore, the length of the movie that is shorter than 94% of the movies about 1.4 hours.

Answer:

The correct option is C

C) 76°

Step-by-step explanation:

The question is incomplete because the figure is not given. I have attached the figure of the same question below. Consult it for better understanding.

We can see in the figure that <2 and <4 are opposite angles, therefore these are equal.

<2 = <4

126 = 7x

x = 18

Similarly we can also see that <5 and <7 are also opposite angles, therefore they are equal too.

<7 = <5

<7 = 4x+4

Substitute x=18

<7 = 4(18) + 4

<7 = 76°

Answer: r=-56

Step-by-step explanation:

multiply 7 on both sides

[tex]\frac{7r}{7}=7\left(-8\right)[/tex]

7*-8=-56

7 and 7 is eliminated

so x=-56

Answer:

r= -56

Step-by-step explanation:

The equation given is:

[tex]\frac{r}{7}= -8[/tex]

We want to solve for r. In order to do this, we must get r by itself.

Currently, r is being divided by 7. We want to perform the inverse, which is multiplication. Therefore, we should multiply both sides of the equation by 7.

[tex]7*\frac{r}{7}= -8 * 7[/tex]

[tex]r=-8*7[/tex]

[tex]r= -56[/tex]

Let's check our solution. Substitute -56 back in for r and solve.

[tex]\frac{r}{7}= -8[/tex]

[tex]\frac{-56}{7}= -8[/tex]

[tex]-8=-8[/tex]

Both sides of the equation are the same, so we know our answer is correct.

Step-by-step explanation:

-3(2c+5)=33

-6c-15=33

-6c=33+15

-6c=48

c=48/6

c=8

Answer:

if you are solving for C it will be -8.

Step-by-step explanation:

Start by dividing both sides of the equation by -3.

2c + 5= -11

Now Subtract 5 from both sides

2c = -11 - 5 (combime like terms) so 2c = -16

Now divide both sides by 2

You will get C= -8

Complementary angles mean that the sum of the angles equals 90 degrees.

This means that

A+B=90

(2x-13)+(4x-5)=90

expand and simplify

2x+4x-13-5=90

6x = 90+18 = 108

x = 108/6=18 degrees.

=>

B=4x-5=4*18-5=72-5=67 degrees

check:

A=2x-13=2*18-13=36-13=23 degrees

A+B=23+67=90 degrees => A and B are complementary

Answer:

f(2)= 2, f(3)= -9

Step-by-step explanation:

To find f(2) o f(3), you simply plug the respective number into the function, substituting it for x:

f(2)= -3(2)^2 + 4(2) + 6

f(2)= -12 + 8 + 6

f(2)= 2

f(3)= -3(3)^2 + 4(3) + 6

f(3)= -27 + 12 + 6

f(3)= -9

Answer:

y ≥ x - 2 and x + 2y < 4

Step-by-step explanation:

There are two lines graphed.

The dotted line passes through (0,2) and (4,0), then:

slope (m): (0 - 2)/(4 - 0) = -1/2

y-intercept (b): 2

equation:

y = mx + b

y = -1/2x + 2

multiplying by 2 at both sides, we get

2y = -x + 4

x + 2y = 4

The inequality is x + 2y < 4 because points below this line are shaded and points on the line are not included.

The solid line passes through (0,-2) and (2,0), then:

slope (m): (0 - (-2))/(2 - 0) = 1

y-intercept (b): -2

equation:

y = x - 2

The inequality is y ≥ x - 2 because points above this line are shaded and points on the line are included.

Answer:

0.43 is the answer

Step-by-step explanation:

you need to take the total of action movie and divide it by the grand total.

204/478 ≈ 0.43

The  probability that a randomly chosen person from this group an action movie is 0.43.

Probability refers to the idea that an event may or may not happen. The scenario described here is a mutually exclusive event. We must recall that in cases of a mutually exclusive event, we add probabilities.

Hence;

Probability of a male watching an action movie = 105/479

Probability of a female watching an action movie = 99/479

probability that a randomly chosen person from this group an action movie = 105/479 +  99/479 = 0.43
