[tex]\\ \rm\Rrightarrow sin52=\dfrac{AC}{BC}[/tex]

[tex]\\ \rm\Rrightarrow sin52=\dfrac{9.2}{B C}[/tex]

[tex]\\ \rm\Rrightarrow B C=9.3[/tex]

Answer:

11.7  (3 s.f.)

Step-by-step explanation:

Given information:

As one of the given angles is 90°, the triangle is a right triangle.

Draw the triangle using the given information (see attached) to help visualize the problem.

To calculate the length of BC, use the sine trigonometric ratio:

[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]

where:

From inspection of the attached triangle:

Substitute the values into the formula and solve for BC:

[tex]\implies \sf \sin(52^{\circ})=\dfrac{9.2}{BC}[/tex]

[tex]\implies \sf BC=\dfrac{9.2}{\sin(52^{\circ})}[/tex]

[tex]\implies \sf BC=11.67496758...[/tex]

[tex]\implies \sf BC=11.7\:\:(3 \:s.f.)[/tex]

Therefore, the length of BC is 11.7 (3 s.f.).

Answer: [tex]54^{\circ}[/tex]

Step-by-step explanation:

Because reflections are rigid motions, we know that [tex]\triangle ABC \cong \triangle A'B'C'[/tex], and thus [tex]\angle B \cong \angle B'[/tex].

It follows that since angles in a triangle add to 180 degrees, [tex]m\angle C'=180^{\circ}-59^{\circ}-67^{\circ}=\boxed{54^{\circ}}[/tex]

Answer:

g^-1(5)=10/3

Step-by-step explanation:

g(x)=3x-5

g(x)= y

g^-1( y)=x

3x-5=y

3x=y+5

x=y+5/3

g^-1(y)=y+5/3

g^-1(5)=5+5/3

g^-1(5)=10/3

Answer: None

Step-by-step explanation:

There is only one pair of angles and one pair of sides, which is not sufficient to prove triangle congruence.

The area, to the nearst square inch, of a circle the same size az the bicycle wheel is  531 inches².

A circle is a bounded figure which points from its center to its circumference is equidistant.

Area of a circle = πr²

Where :

π = pi = 22/7

R = radius

The full rotation of the wheel is equal to the circumference of the wheel.

circumference of the wheel = 2 πr

26π = 2 πr

r = 13 inches

Area = 22/7 x 13³ = 531 inches²

The correct function shown in the graph is,

⇒ log₁₀ (ax) = 1

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

It has been given that the point (3,1) is on the graph. For the point (3,1) to be on the graph, the following must hold true:

⇒ log₁₀ (ax) = 1

or , ax = 10¹ = 10

Thus, x  = 10/a

So, in order for the point (3,1) to lie on the graph, of all the given options the closest we can get is when we have Option D, that is, when a = 3. That will make x = 3.33 and thus, .

⇒ log (3 × 3.33) = 0.99 ≈ 1

Thus, out of the given options only Option D seems to be the most probable answer.

Answer:

  260 square feet

Step-by-step explanation:

The area of a rectangle is given by the formula ...

  A = LW

The area of two same-size rectangular rooms will be double the area of one of them.

__

Each room has an area of ...

  A = LW = (13 ft)(10 ft) = 130 ft²

The order for carpet must be for 2 times the area of one room:

  carpet order = 2 × 130 ft² = 260 ft²

The measure of ∠ABP and ∠ABC are 32° and 64° respectively.

Any line which divides an angle into two equal halves is a bisector of that angle.

Analysis:

Since the arcs at D and E are drawn with the same radius and arc using center D and E are intersected by line PB( which is the bisector of the full arc with center B) then ∠ABP = ∠PBC = 32°.

∠ABC = ∠ABP + ∠PBC

∠ABC = 32 + 32 = 64°

In conclusion, ∠ABP and ∠ABC are 32° and 64°

The linear function that has a different rate of change from y = -3x+4 is A, a function with a y-intercept of -4 that passes through the point (-3,-13)

An intercept is the point where a straight line or a curve meets with the x or y axes.

Analysis:

The rate of change is the same as slope. The slope of y = -3x + 4 is -3,

All other functions Except A have a slope of -3.

for linear function A,

if y = mx + c, c = -4, x = -3, y = -13

-13= -3m - 4

-3m = -9

m = 3

In conclusion, linear function A with a y-intercept of -4 passing through the point (-3,-13) has a different rate of change from y = -3x + 4

Answer:

c = speed of current = 3 km/hr

r = speed of boat in still water = 15 km/hr

Step-by-step explanation:

Use the formula distance = time x rate to set up these equations

45 = 2.5 (r+c)

39 = 3.25 (r-c)

(r + c) is the speed of the boat added to the speed of the current, downstream

(r - c) is the speed of the boat minus the speed of the current, upstream

Use one equation to isolate a variable then substitute it into the other equation to solve the system.

39/3.25 = r - c

12 + c = r

45 = 2.5 ( 12 + c + c )

18 = 12 + 2c

6 = 2c

c = 3

Then use the equation 12 + c = r from above

12 + c = r

12 + 3 = 15

r = 15 km/hr

The linear equation will be 2x + 10 = 5(x - 6). Then the value of the variable x will be 23.33.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Translate then Solve for the variable:

The sum of two times a number and 10 is five times the difference between a number and six.

Let the number be x.

Then the equation will be

2x + 10 = 5(x - 6)

Then the value of x will be

2x + 10 = 5x - 60

5x - 2x = 60 + 10

      3x = 70

        x = 23.33
