Answers

Answer 1

Answer:

Step-by-step explanation:

When A 757 Passenger Jet Begins Its Descent To The Ronald Reagan National Airport In Washington, D.C.,

Answer 2

The plane's horizontal distance from the ground is 409.91 ft and the plane must fly 37310.411 ft before it descends to the ground.

Data;

Distance of the place from the ground = 3900 ftangle of depression = 6 degree

Trigonometric Ratio

This is a geometric method used to find the side or angle of a right angle triangle.

The plane's ground horizontal distance from the airport

To find the plane's ground distance from the airport, we have to use trigonometric ratio

The plane distance from the ground (opposite) = 3900The angle = 6 degreeThe plane's horizontal distance from the ground (adjacent) = y

From SOHCAHTOA

Using tangent of the angle

[tex]tan \theta = \frac{opposite}{adjacent}\\ tan 6 = \frac{3900}{y}\\ \\y = 37106.02ft[/tex]

The plane's horizontal distance from the ground is 409.91 ft.

How far must the plane fly before it descend to the ground

Using the values above,

Taking the sine angle of this since we have the value of angle and opposite.

[tex]sin\theta = \frac{opposite}{hypothenuse}\\ sin6 = \frac{3900}{x}\\ x = \frac{3900}{sin6}\\ x = 37310.411ft[/tex]

The plane must fly 37310.411 ft before it descends to the ground.

Step-by-step explanation:

"The electric bill reflected a monthly fee of $42.00 as well as a kilowatt per hour charge of $0.0953 for electricity used. Which function determines the amount of electricity used based on the total bill cost? Group of answer choices"

Given data

monthly fee= $42

kilowatt per hour charge=$0.0953

let the number of hours be =x

let the expression be patterned after the model\

y=mx

here y=42

m=0.0953

We want to find x, the amount of electricity used

42=0.0953x

divide both sides by 0.0953 we have

42/0.0953=x

x=440.71

A tree casts a shadow 10 feet long. This person standing next to the tree casts a shadow 2.5 feet long. The triangle shown for the tree and its shadow
is proportional to the triangle shown for the person and their shadow. If this person is 5 feet tall, how tall is the tree?

Answers

Answer:

B/c the person is 5 feet tall but only casts a shadow 2.5 feet.. that's 1/2 his height, so the tree must also be casting a shadow 1/2 of it's height too, therefore the tree must be 20 feet tall

Answers

Answer:

The equation of a line with slope 0 and y-intercept -6 in slope-intercept form is [tex]y = -6[/tex].

Step-by-step explanation:

From Analytical Geometry we know that equation of the line in slope-intercept form is represented by:

[tex]y = m\cdot x + b[/tex] (Eq. 1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]m[/tex] - Slope, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

If we know that [tex]m = 0[/tex] and [tex]b = -6[/tex], then the equation of the line is:

[tex]y = 0\cdot x +(-6)[/tex]

[tex]y = -6[/tex]

The equation of a line with slope 0 and y-intercept -6 in slope-intercept form is [tex]y = -6[/tex].

Answers

Answer:

Y = - 0.2X + 5

Step-by-step explanation:

Given that:

Distance between Leah's home and friend's house = 5 miles

Distance X:

After 5 minutes, she is 4 miles from home

After 15 minutes, she is 2 miles from home

Hence ;

Change in distance with time (slope) :

(2 - 4) / (15 - 5) = -2 / 10 = -0.2

Initial distance from home (intercept) = 5

Hence, using the linear equation model:

Y = mx + c

m = slope or gradient ; c = intercept

Y = - 0.2X + 5

The figure is rotating clockwise

Step-by-step explanation:

Let us revise the cases of rotation

1. Rotation with positive direction (anti-clockwise)

- If the point (x, y) rotated about the origin by angle 90° anti-clockwise

∴ Its image is (-y, x)

- If the point (x, y) rotated about the origin by angle 180° anti-clockwise

∴ Its image is (-x, -y)

- If the point (x, y) rotated about the origin by angle 270° anti-clockwise

∴ Its image is (y, -x)

2. Rotation with negative direction (clockwise)

- If the point (x, y) rotated about the origin by angle 90° clockwise (-90°)

∴ Its image is (y, -x)

- If the point (x, y) rotated about the origin by angle 180° clockwise (-180°)

∴ Its image is (-x, -y)

- If the point (x, y) rotated about the origin by angle 270° clockwise (-270°)

∴ Its image is (-y, x)

From the given

∵ The figure is rotating around the origin by d degrees

∵ d < 0, which means d is negative

→ According to rule 2 above

∴ The direction of rotation is clockwise

∴ The figure is rotating clockwise

If the sales person only makes a 2% commission then we need to do 2% of 233.75

A business orders 215 flowers for their employees on Valentine's Day. Roses cost $3.00 each, carnations cost $1.00 each, and lilies cost $2.00 each. There are 15 more lilies than roses. The total of the order came to $410.00. How many of each type of flower were ordered?

Answers

Let, number of roses, carnations and lilies are x, y and z respectively.

So,

x + y + z = 215 ....1 )

It is given that total cost is $410.00 :

3x + y + 2z = 410 ....2 )

Also, there are 15 more lilies than roses.

z = x + 15 ....3 )

Putting value of z in eq 1 and 2 , we get :

x + y + x + 15 = 215

2x + y = 200 ....4 )

3x + y + 2( x + 15 ) = 410

5x + y = 380 ....5 )

Solving equation 4 and 5, we get :

3x = 180

x = 60

z = 60 + 15 = 75

y = 215 - 60 - 75 = 80

Therefore, number of roses, carnations and lilies are 60, 80 and 75 respectively.

Hence, this is the required solution.

A computer game involves creating words of five or more letters. At the beginning of each game, the computer assigns a points value of 1, 2, 3 or 4 to each letter of the alphabet, at random.
In the game that I am currently playing I have so far scored 14 points for EARTH, 12 points for CHART and 11 points for TRACE.
How many points would TEACHER score in this game? SHOW YOUR WORK

Answers

9514 1404 393

Answer:

Step-by-step explanation:

EARTH - TRACE = H - C = 14 - 11 = 3

For the given possible numerical values of the letters, the difference H - C = 3 means that ...

H = 4, C = 1

Then ...

CHART = ART + C + H = ART + 1 + 4 = 12

ART = 7

So, ...

TEACHER = EARTH +TRACE -ART = 14 +11 -7

TEACHER = 18
