A vessel sails 41 miles S 35° E. How far south has it sailed?

const2013 [10]

Option A: The vessel has sailed 34 miles South

Explanation:

Given that the vessel sails 41 miles S 35° E.

We need to determine the how far south the vessel has sailed.

Let us use the Pythagorean theorem to find the distance of the vessel has sailed.

Thus, we have,

$cos \ \theta=\frac{adj}{hyp}$

Substituting $\theta=35^{\circ}$ , $adj=x$ and $hyp=41$

Hence, we get,

$cos \ 35=\frac{x}{41}$

Simplifying, we have,

$0.82=\frac{x}{41}$

Multiplying both sides by 41, we have,

$33.62=x$

Rounding off to the nearest integer, we have,

$34=x$

Thus, the vessel has sailed 34 miles South.

Therefore, Option B is the correct answer.

Billy left home at 9 a.M. And rode his bicycle to the park at an average speed of 10 miles per hour here I got the park at 9:30

tamaranim1 [39]

Answer:

Park is 5 miles from Billy's home.

Step-by-step explanation:

Given:

Billy left home at 9 a.m. And rode his bicycle to the park at an average speed of 10 miles per hour here and got the park at 9:30 a.m.

Now, to find the distance from park to Billy,s home.

Time it took Billy to rode his bicycle from park to home is from 9.30 a.m to 9.30 p.m.

So, the time = (9.30 - 9.00) = 30 minutes

$=\frac{30}{60}$ $=0.5\ hour.$

Speed = 10 miles per hour.

Now, to get the distance from park to Billy's home we put formula:

$Distance=Speed\times Time.$

$Distance=10\times 0.5$

$Distance=5\ miles.$

Therefore, park is 5 miles from Billy's home.

Which of the following equations is non-linear?

lakkis [162]

2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Step-by-step explanation:

Lets define a linear equation first.

A linear equation is an equation in which there is no variable with exponent greater than 1 or the degree of the equation is 1.

So,

x + 12 = -8x + 10 - 2y

The equation is a linear equation because the degree of the equation is 1.

x = 8x + 19 - 10y

The equation is a linear equation because the degree of the equation is 1.

2x + 6y = 14y - 19x^2 + 12

The equation involve a term with exponent 2 which makes the degree of the equation 2 making it a quadratic equation

2x + 13y + 14x - 7 = 16y - 3

The equation is a linear equation because the degree of the equation is 1.

Hence,

2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Keywords: Linear, quadratic

Pls help me help me pls

grin007 [14]

Answer:

Point B

Step-by-step explanation:

Lines given:

y= 2/5x - 1/2
y= -1/3x +2/3

x coordinate of intersection of given lines is:

2/5x - 1/2= -1/3x+2/3
2/5x+1/3x= 2/3 +1/2
6/15x+5/15x= 4/6+3/6
11/15x=7/6
x= 7*15/11*6
x= 35/22

For this value of x, the value of y is:

y= 2/5*35/22 - 1/2
y=14/22- 1/2
y= 3/22

As per graph point (35/22, 3/22) is point B
