Answer:

m∠B ≈ 41.81°

Step-by-step explanation:

If we draw a picture, it would help a lot. Once we visualize the triangle, we can see that we have sin∅ = 2/3. So, plugging into your calc,

sin∅ = 2/3

∅ = sin^-1(2/3)

∅ = 41.8103

Step-by-step explanation:

Answer:

false

Step-by-step explanation:

f is not a function because you can see that two of the points are (2,5) and (2,2). A function can only have one corresponding y-coordinate for every x-coordinate and since this is not the case here, f is not a function.

Answer: C.) 4/27

Step-by-step explanation:

Given that:

One out of three cards is a winner :

P(winning) = 1 / 3

Therefore, P(not winning) = P(losing) :

1 - P(winning) = 1 - 1/3 = 2/3

Probability that shenice will first win on her third try can be interpreted as:

1st try = lose, 2nd try: lose, 3rd try : win

P(losing) × p(losing) × p(winning)

(2/3) × (2/3) × (1/3)

4 / 27

Probability of first winning on third try = 4/27

Answer:

In the figure attached, the solution is shown.  

Step-by-step explanation:

Given the inequality:

|x| < 3

There are 2 solutions:

x < 3 or x > -3

This can be rewritten as follows:

-3 < x < 3

On the number line, this represents all the point between -3 and 3. Notice that -3 and 3 are not included in the solution; that is why there are open circles at these points on the graph.

Answer: $500

Step-by-step explanation:

Hi, since both credit options accumulate the same amount of interest:

1000+125x=1300+110x

Solving for x(number of months)  

125x-110x =1300-1000

15x = 300

x =300/15

x= 20 months

Replacing x =25 in one equation:

1000+125x =

1000+125(20)=

1000+2500= $3500

Finally, we have to subtract the amount of the purchase (3000) to the result obtained:

3500-3000=$500

Answer:

C). Zero

Step-by-step explanation:

This is a pretty simple question.

Any number multiplied by zero will be zero, and zero cannot have a positive or negative sign, which is why zero has its own sign, which is known as the Sign of Zero.

Answer:

No; the slopes of segment LM and segment LN are not opposite reciprocals

Step-by-step explanation:

slope of LM: (2 - 0)/(2 - 0)  = 1

slope of LN: (-1 - 0)/(2 - 0) = -1/2

Two lines are perpendicular when the multiplication of their slopes is equal to negative one, that is, they are opposite reciprocals. In this case:

slope of LM*slope of LN = 1*(-1/2) = -1/2

The correct option is

No; the slopes of segment LM and segment LN are not opposite reciprocals

slope of LM: [tex](2 - 0)\div (2 - 0)[/tex]  = 1

And,  

slope of LN: [tex](-1 - 0)\div (2 - 0)[/tex]= [tex]-1\div 2[/tex]

Here two lines should be perpendicular at the time  when the multiplication of their slopes is equalivalent to negative one.  

So,  

= slope of LM × slope of LN

[tex]= 1\times (-1\div 2)\\\\ = -1\div 2[/tex]

Answer: The radius and the cord must be perpendicular to each other.

Step-by-step explanation:

A cord is a line from a point of circumference of a circle to another point of the circumference of the circle without passing through the centre.

A radius is a line from the centre of a circle to the circumference of the circle.

When the radius line intersect and bisects a cord of a circle, the radius and the cord must be perpendicular to each other.

Answer:

if in a circle a radius bisects a chord then the radius is perpendicular to the chord,

Answer:

(B) The electrician charges $40 per hour.

Step-by-step explanation:

Total cost=fixed cost + variable cost

F(x)=60+40x

Fixed cost =60

Variable cost=40x

x=hours of service

40=40 dollar per hour charge

The coefficient 40 represent the electrician charge of $40 per hour

(B) The electrician charges $40 per hour.

Answer:

Perimeter of the rectangle is 16x+18 units.

Step-by-step explanation:

The area of rectangle is

[tex]7x^2+57x+8[/tex]

First we have to find the factor form of above expression.

Splitting the middle term, we get

[tex]7x^2+56x+x+8[/tex]

[tex]7x(x+8)+1(x+8)[/tex]

[tex](x+8)(7x+1)[/tex]

Area of a rectangle is the product of its dimensions. It means dimensions of the rectangle are (x+8) and (7x+1).

Perimeter of a rectangle is

[tex]Perimeter=2(l+b)[/tex]

[tex]Perimeter=2[(x+8)+(7x+1)][/tex]

[tex]Perimeter=2[8x+9][/tex]

[tex]Perimeter=16x+18[/tex]

Therefore, the perimeter of the rectangle is 16x+18 units.

Step 2: Mulitply the 2 exponents together

Answer:

Smallest angle - ∠M

Largest angle - ∠N

Step-by-step explanation:

In a triangle opposite side of a largest angle is largest and opposite side of a the smallest angle is smallest.

In the given triangle LMN,

Side lengths of the triangle have been given as,

LM = 27 in.

MN = 25 in.

LN = 24 in.

Relationship in these sides will be,

LM > MN > LN

Therefore, relationship in their opposite sides will be,

∠N > ∠L > ∠M

The smallest angle of the triangle is angle M.

And the largest angle of the triangle is angle N.

Answer:

C). y = ln x + 4

Step-by-step explanation:

First off, we can cancel out the [tex]e^{x}[/tex] graphs.

Now looking at the graph, one can see that when x = 1, y = 4.

So for each [tex]ln[/tex] function, plug in 1 for x.

In doing this, one will find that y = ln x + 4 is the only [tex]ln[/tex] graph that produces 4 when x = 1.

Answer:

x=35

Step-by-step explanation:

Since a quadrilateral's interior angles add up to 360°, we get this:

360-85-20=360-4x+x

340-85=360-3x

255=360-3x

-105= -3x

Multiply both sides by -1

105=3x

3x=105

Divide both sides by 3

x=35

Answer:

The yellow trapezoid equals to 6.

Step-by-step explanation:

Assuming that two green items equals to two purple items and one yellow trapezoid, we can make the equation 5+5=2+2+x. Simplifying both sides, we get 10=4+x. If we subtract 4 from both sides and isolate x, we get that x=6.

Answer:

yellow trapezoid = 6

Step-by-step explanation:

since the green crescent equals 5, and there are two on the left side, that would equal 10, so the right side also should equal 10 too. The purple teardrops equal two, and there are two on the right side, so the total of teardrops on the right side is equal to 4. Since both sides need to equal to 10, and we only have 4, we need to find the amount of the yellow trapezoid. To do that you need to subtract 4 from 10, to get 6, which is the amount of the yellow trapezoid.
