A person leaves home and walks 4 miles west, then 5 miles southwest.
How far from home is she?
miles
In what direction must she walk to head directly home?
degrees North of East
Answers
The person is approximately 8.43 miles from home, and they need to walk in the direction of approximately 26.6 degrees east of north to head directly home.
To determine the distance from home, we can use the concept of vector addition. The person walks 4 miles west, which can be represented as a vector (-4, 0) in a coordinate plane. Then, they walk 5 miles southwest, which can be represented as a vector (-3.54, -3.54) since southwest is a combination of west and south. Adding these two vectors together gives us (-7.54, -3.54).
To find the magnitude or distance from home, we use the Pythagorean theorem. The distance is given by sqrt((-7.54)^2 + (-3.54)^2) = 8.43 miles (approximately).
To determine the direction to head directly home, we need to find the angle between the vector (-7.54, -3.54) and the positive x-axis. We can use trigonometry to find this angle. The tangent of the angle is given by the ratio of the y-coordinate to the x-coordinate, which is -3.54 / -7.54. Taking the inverse tangent of this value gives us approximately 26.6 degrees.

Tim is saving up money to go to
Disneyland. The tickets for Disneyland cost
$130. He has already saved up $4. If he is able
to save $18 per week, how many weeks will it
take him to save enough money to buy a
ticket?
Answers
Answer:
7 weeks
Step-by-step explanation:
130-4 = 126
126÷18=7
Answer:
7
Step-by-step explanation:
Since he has already saved up four dollars, we can subtract this amount from $130.
We are now left with $126, which we can divide by 18, the amount saved per week.
126/18 is equal to 7, so it will take him 7 weeks to buy a ticket.

choose the equation below that represents the line passing through the point (-2,-3) with a slope of -6
Answers
The equation of the line is: y + 3 = -6(x + 2) [point-slope form] or y = -6x - 15 [slope-intercept form].
How to Write the Equation of a Line?Given a point (-2, -3) and a slope (m) of -6, you can write the equation of the line in point-slope form by substituting (a, b) = (-2, -3) and m = -6 into y - b = m(x - a):
y - (-3) = -6(x - (-2))
y + 3 = -6(x + 2) [point-slope form]
Rewrite in slope-intercept form as:
y + 3 = -6(x + 2)
y + 3 = -6x - 12
y = -6x - 12 - 3
y = -6x - 15 [slope-intercept form]

Suppose that 650 lb of coffee are sold when the price is $4 per pound, and 400 lb are

a. List the data points as ordered pairs (use price as the independent variable).
b. Find the slope of the line.
c. Interpret the meaning of the slope in the context of this problem. Write the
interpretation in a complete sentence with proper grammar and correct spelling.
d. Use the point-slope form to write a linear equation for this data.
Then write the final answer in function notation.
e. Use this function to predict how much consumers would be willing to buy at a
price of $6 per pound.
Answers
a. The data points are (4, 650) and (8, 400).
b. The slope of the line is -62.5.
What is a Slope?A number that describes a line's direction and steepness is known as the slope or gradient of a line in mathematics.
How to find the slope:
To find the slope of the line, we can use the formula: slope = (y2 - y1) / (x2 - x1).
Plugging in the values from our data points, we get: slope = (400 - 650) / (8 - 4) = -250 / 4 = -62.5.
c. The slope of the line represents the change in the amount of coffee sold for each unit change in price.
In this case, a negative slope of -62.5 means that for every increase of $1 in the price, the amount of coffee sold decreases by 62.5 pounds.
d. To write the equation of the line using the point-slope form, we need a point from our data and the slope.
We'll use (4, 650) as our point and the slope of -62.5 that we found earlier.
The point-slope form is: y - y1 = m (x - x1), where m is the slope and (x1, y1) is the point.
Plugging in our values, we get: y - 650 = -62.5 (x - 4).
Rearranging, we get: y = -62.5 x + 650 + 62.5 * 4 = -62.5 x + 762.5.
e. To predict the number of coffee consumers would be willing to buy at a price of $6 per pound, we can plug in x = 6 into our equation and solve for y.
y = -62.5 x + 762.5, so y = -62.5 * 6 + 762.5 = 450.
This means that at a price of $6 per pound, consumers would be willing to buy 450 pounds of coffee.

2. If 3x equal to 243, find X^2
Answers
The value of y from the equation \(27^y=\sqrt{3}\) is 1/6 and the value of x² from the equation 3x=243 is 6561.
Given that, \(27^y=\sqrt{3}\) and 3x=243.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The equation \(27^y=\sqrt{3}\) can be solved as follows:
That is, \((3^3)^y=3^{(\frac{1}{2} )\)
⇒3y=1/2
⇒y=1/6
The equation 3x=243 can be solved as follows:
That is, x=243/3
⇒x=81
So, x²=81²=6561
Therefore, the value of y from the equation \(27^y=\sqrt{3}\) is 1/6 and the value of x² from the equation 3x=243 is 6561.

9. A has some amount of money with him. He gave one half of one third from that amount One half of the amount received by B is 20. What is the amount that A originally had?
Answers
Using the expression 5x/12 = 20, the amount that A originally had was $48.
We have,
Let x be the amount of money that A originally had.
Then, A gave away 1/2 x 1/3 = 1/6 of the amount, which is equal to x/6.
The amount received by B is 1/2 of the remaining amount,
which is (x - x/6)/2 = 5x/12.
We know that 5x/12 = 20,
Solving for x.
5x/12 = 20
5x = 240
x = 48
