Since the roof of one building is 400 feet below the roof of another building, the buildings are 571 ft apart.

The line of sight of the lower building to the taller building, the distance of the buldings apart, D and the height of the lower building below the taller building, h form a right angled triangle with angle Ф = 35° = angle of elevation of taller building and opposite side, h.

From trigonometric ratios, we have that

tanФ = h/D

So, D = h/tanФ

Since

Substituting the values of the variables into the equation, we have

D = h/tanФ

D = 400 ft/tan35°

D = 400 ft/0.7002

D = 571.27 ft

D ≅ 571 ft to the nearest foot

So, the roof of one building is 400 feet below the roof of another building, the buildings are 571 ft apart.

The graph of the line with the given slope that passes through (-3, 3) is shown in the image attached below.

The equation in slope-intercept form of a line, is y = mx + b, where:

b = y-intercept

m = slope = change in y/change in x.

Given a line with slope = 2 and passes through (-3, 3), plug in m = 2 and (a, b) = (-3, 3) into y - b = m(x - a) to write the equation of the line

y - 3 = 2(x - (-3))

Rewrite in slope-intercept form

y - 3 = 2x + 6

y = 2x + 6 - 3

y = 2x + 3

Therefore, the graph of the line with the given slope that passes through (-3, 3) is shown in the image attached below.

Answer:

the slope is 2

y=2x-1

Step-by-step explanation:

y(2)-y(1)/x(2)-x(1) is the formula for slope

-1-0/0-0.5=-1/0.5=2

however, it is looking for the equation

y=mx+b

(b=y intercept)

m=slope

y=2x-1

Answer:

Step-by-step explanation:

The equation of a line is y = m*x + b

So plug in the numbers...

the slope is the change in y over the change in x or (y - y₁)/(x - x₁)

(-1 - 0)/(0 - 0.5) = 2

so... m = 2

and b is the y-intercept which is -1

therefore the answer is: y = 2x - 1

Answer: The width of the rectangle is 5 cm and the length is 13 cm

Step-by-step explanation:

Let the width be x cm

Let the length be (x+8) cm

Area = 65cm²

[tex]\Rightarrow x(x+8)=65 \ [\because$ Area of rectangle $=$ length $\times$ width $]$ \\$\Rightarrow x^{2}+8 x-65=0 \Rightarrow x^{2}+13 x-5 x-65=0$ \\$\Rightarrow x(x+13)-5(x+13)=0 \Rightarrow(x+13)(x-5)=0$ \\$\Rightarrow x=-13$ or $x=5$ \\But width car't be negative. so $x=5$ \\[/tex]

Therefore:

Width = 5 cm

Length = 5 + 8 = 13 cm

The vertex of the graph is:

As this parabola opens upwards, the vertex is the minimum point.

From inspection of the graph, vertex = (-3, -1)

Total number of cars: 10 + 4 + 6 = 20

Number of cars that turned left: 4

p(left) = 4/20 = 0.2

Step-by-step explanation:

The points A,B,C,D make up the circumference of the circle

The measure of angle BAD is 65 degrees

The measure of angle ODB is given as:

ODB = 25 degrees

Considering the triangle BOD, we have:

ODB + BOD + DBO = 180

Where:

ODB = DBO = 25

So, we have:

25 + BOD + 25 = 180

Solve for BOD

BOD = 130 degrees

The angle at an arc is twice the angle at the circumference.

So, we have:

BOD = 2 * BAD

Substitute 130 for BOD

130 = 2 * BAD

Divide both sides by 2

65 = BAD

Hence, the measure of angle BAD is 65 degrees

Answer:

  a. f = 17.5/c

  b. 8.75 N

Step-by-step explanation:

Inverse variation means one variable is proportional to the inverse of the other. The equation for that is ...

  f = k(1/c) . . . . . . force (f) is proportional to the inverse of distance (c)

We find the value of k using data given for a specific instance.

  3.5 N = k(1/(5 cm)) . . . . use the given values

  17.5 N·cm = k . . . . . . multiply by the denominator

Then the equation of interest is ...

  f = 17.5/c . . . . . . . where c is in cm, and f is in newtons

__

Using the above equation, we find the force to be ...

  f = 17.5/2 = 8.75 . . . . newtons

_____

Additional comment

We often look at several different kinds of proportionality:

and there are combinations of these, such as ...

You may have noticed that when x and y are inversely proportional, their product is a constant. y = k/x  ⇒  xy = k

__

We have left off the units of k in the problem above. Sometimes it is a good idea to retain them, or to pay close attention to what they are. This can avoid using the wrong measures for the variables.

  f = (17.5 N·cm)/(2 cm) = 8.75 N . . . . . units of cm cancel

If rena divides a square into 8 equal part then 1/8 is a unit fraction which she has to write as a label for each parts.

A fraction represents a part of a whole.

Given that rena divides a square into 8 equal part.

A division is a process of splitting a specific amount into equal parts.

Let the whole square is divided into eight equal parts.

Which can be represented by 1/8.

Where the numerator 1 represents the whole and eight represents the parts.

The unit fraction for each part is 1/8 because the square is divided into 8 equal parts.

This means each part is one eighth of the whole.

Hence, if rena divides a square into 8 equal part then 1/8 is a unit fraction which she has to write as a label for each parts.
