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

Answer:

-10p^4q

Step-by-step explanation:

In order to find the cube root of this expression, take the cube root of each part:

- 1000, p^12, and q^3

Remember, to take the cube root of a number in the form of x^y, simply divide y by 3.

∛-1000 = -10

∛p^12 = p^4

∛q^3 = q^1 = q

Therefore, the cube root of the expression -1000p^12q^3 is -10p^4q.

Answer:

x ≈ 6.9

Step-by-step explanation:

We use tan∅ to solve this:

tan21° = x/18

18(tan21°) = x

x = 6.90955

Answer:

Solution,

X=8

y=4

Now,

[tex] \frac{x + 10}{y + 5} \\ = \frac{8 + 10}{4 + 5} \\ = \frac{18}{9} \\ = 2[/tex]

Answer:

Step-by-step explanation:

x^4 – 16x^3 + 96x^2 – 256x + 256

terms with odd exponents are negative

x^4 has a coefficient of one, so the expression's GCF is 1

Thus, we need to factor out the expression as it is:

(x-4)*(x-4)*(x-4)*(x-4)

Lets multiply it out to check:

(x-4)*(x-4)*(x-4)*(x-4)=

(x^2-8x+16)*(x^2-8x+16)=

x^4−8x^3+16x^2−8x^3+64x^2−128x+16x^2−128x+256=

x^4 – 16x^3 + 96x^2 – 256x + 256

thus, the factored form is:

(x-4)*(x-4)*(x-4)*(x-4) or (x-4)^4

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:

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.

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:

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.

Step-by-step explanation:

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:

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

The inside diameter of the pipe is 4.68 inches.

A straight line that runs through the sideways of a body or figure, particularly a circle or sphere, is called as a diameter of a circle or sphere.

Given:

The outside diameter of a pipe is 4.825 inches.

If the pipe wall is 0.145 inches thick,

the inside diameter of the pipe,

= 4.825 - 0.145

= 4.68

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.) 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
