Answer:

C. 15.7 feet

Step-by-step explanation:

9/cos(55 deg)=

15.691.

round it up, and the length of the beam is 15.7 feet.

The length of the beam is 15.7 foot.

Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.

For the given situation,

A beam rests against a wall, forming a angle with the floor = 55 degree

The function is y = 9 secθ

The length of the beam is

⇒ [tex]y = 9 sec\theta[/tex]

⇒ [tex]y = 9 sec55[/tex]

we know that secθ = 1/cosθ

⇒ [tex]y = 9 (\frac{1}{cos55})[/tex]    

⇒ [tex]y=15.69[/tex]

⇒ [tex]y=15.7[/tex]

Hence we can conclude that the length of the beam is 15.7 foot.

Step-by-step explanation:

Answer:

The two hypotenuses.

Step-by-step explanation:

HL or Hypotenuse-Leg Theorem: two right triangles are congruent if and only if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of the other right triangle.

Since we already know the bottom leg of each triangle is congruent, we only need to know the two hypotenuses.

Answer:

The bounded area is 5 + 5/6 square units. (or 35/6 square units)

Step-by-step explanation:

Suppose we want to find the area bounded by two functions f(x) and g(x) in a given interval (x1, x2)

Such that f(x) > g(x) in the given interval.

This area then can be calculated as the integral between x1 and x2 for f(x) - g(x).

We want to find the area bounded by:

f(x) = y = x^2 + 1

g(x) = y = x

x = -1

x = 2

To find this area, we need to f(x) - g(x) between x = -1 and x = 2

This is:

[tex]\int\limits^2_{-1} {(f(x) - g(x))} \, dx[/tex]

[tex]\int\limits^2_{-1} {(x^2 + 1 - x)} \, dx[/tex]

We know that:

[tex]\int\limits^{}_{} {x} \, dx = \frac{x^2}{2}[/tex]

[tex]\int\limits^{}_{} {1} \, dx = x[/tex]

[tex]\int\limits^{}_{} {x^2} \, dx = \frac{x^3}{3}[/tex]

Then our integral is:

[tex]\int\limits^2_{-1} {(x^2 + 1 - x)} \, dx = (\frac{2^3}{2} + 2 - \frac{2^2}{2}) - (\frac{(-1)^3}{3} + (-1) - \frac{(-1)^2}{2} )[/tex]

The right side is equal to:

[tex](4 + 2 - 2) - ( -1/3 - 1 - 1/2) = 4 + 1/3 + 1 + 1/2 = 5 + 2/6 + 3/6 = 5 + 5/6[/tex]

The bounded area is 5 + 5/6 square units.

Answer:

1 and -3

Step-by-step explanation:

To solve for the roots (x-1)(x+3) set x-1 to = 0 and solve for x. Same thing for x+3.

Answer:

1, and -3

Step-by-step explanation:

So when looking for roots, we take our quadratic equation that is in factored form, and set each partheasese to 0:

x-1=0 and x+3=0

Now just subtract and add the -1 and +3 to both sides:

x=1 and x=-3

These are your 2 answers for the quadratic.

Answer:

Square

Step-by-step explanation:

Area of triangle = 1/2 * b * h

= 1/2 * 15 * 25

= 187.5 ft²

Area of square = side * side

= 14 * 14

= 196 ft²

Comparing both areas, it is clear that square have a larger area.

Answer:

Step-by-step explanation:

length of Legs of the right angle triangle = 22 (unit) and 26 (unit)

To find the length of hypotenuse of the right angle triangle, we have to use Pythagoras property

Lets keep hypotenuse as "h" and one leg as  "a" and another as "b"

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]h^{2}[/tex]

[tex]22^{2}[/tex] + [tex]26^{2}[/tex] = [tex]h^{2}[/tex]

484 + 676 = [tex]h^{2}[/tex]

[tex]h^{2}[/tex] = 1,160

h = [tex]\sqrt{1,160}[/tex]

h = 34.05 (unit)

Step-by-step explanation:

remember that the circumference of a circle is 2πr

so 3.15x8 and then multiply by two

Answer:

200.96 ft²

Step-by-step explanation:

Step 1: Define/formula

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

[tex]a=\pi r^2(3.14*radius*radius)[/tex]

Step 2: Solve

According to the word problem, the radius is 8.

From here, we plug the numbers into the formula.

[tex]\pi 8^2(3.14*8*8)=200.96ft^2.[/tex]

Step 3: Conclude

Therefore, the area of this circle is 200.96 ft.²

Answer:

[tex]\overline {DE} \parallel \overline{AB}[/tex] because [tex]\frac{EC}{DC} = \frac{AC}{BC}[/tex].

Step-by-step explanation:

According to the Theorem of Thales and definition of proportionality, [tex]\overline {DE} \parallel \overline{AB}[/tex] if and only if [tex]\frac{EC}{DC} = \frac{AC}{BC}[/tex]. If we know that [tex]EC = 15\,cm[/tex], [tex]DC = 20\,cm[/tex], [tex]BC = 36\,cm[/tex] and [tex]AC = 27\,cm[/tex], then we have the following result:

[tex]\frac{15\,cm}{20\,cm} = \frac{27\,cm}{36\,cm}[/tex]

[tex]\frac{3}{4} = \frac{3}{4}[/tex]

Hence, [tex]\overline {DE} \parallel \overline{AB}[/tex].

We need to simpify the given expression. The given expression to us is ,

Given Expression :-

[tex]\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta }[/tex]

Using Identity :-

[tex]\sf\implies \red{ sin^2\theta + cos^2\theta = 1}[/tex]

So that :-

[tex]\sf\implies - sin^2\theta = cos^2\theta -1[/tex]

We have :-

[tex]\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta } \\\\\sf\implies\dfrac{ - sin^2\theta}{4sin^2\theta}=\boxed{\sf -\dfrac{1}{4}} [/tex]

Hence the required answer is -1/4.

A. The graph doesn't make sense to me. 2 would be 8 not 6 according to the problem.

The Graph would be:

1:4

2:8

3:12

4:16

5:20

6:24

B. I would make this equation: 4x = y

X is representing how many steps Audrey takes.

So then substitute:

4 · 50 = 200

Meg would travel 200 feet.
