4. Determine the magnitude and direction of the vector v = <5, -6>.
f. 11, NE
g. 61, SE
h. 111, NE
j. V61, SE
Answer:
The magnitude of vector is:
[tex]\left|\begin{pmatrix}5&-6\end{pmatrix}\right|=\sqrt{61}[/tex]
v = <5, -6> means the vector has x-coordinate x = 5 and y-coordinate y = -6, so the vector v = <5, -6> is heading towards SE.
Thus, option ( j ) is correct.
i.e. [tex]\sqrt{61},\:SE[/tex]
Step-by-step explanation:
Given the vector
v = <5, -6>
Determining the magnitude of the vector
To find a magnitude of a vector v = (a, b) we use the formula
[tex]||v||\:=\:\sqrt{a^2+b^2}[/tex]
Magnitude of the vector is basically termed as the length of the vector, which is denoted by
[tex]|\left(5,\:-6\right)|=\sqrt{\left(5\right)^2+\left(-6\right)^2}[/tex]
[tex]=\sqrt{5^2+6^2}[/tex]
[tex]=\sqrt{25+36}[/tex]
[tex]=\sqrt{61}[/tex]
Thus, the magnitude of vector is:
[tex]\left|\begin{pmatrix}5&-6\end{pmatrix}\right|=\sqrt{61}[/tex]
As the vector v = <5, -6> lies in 4th quadrant.
v = <5, -6> means the vector has x-coordinate x = 5 and y-coordinate y = -6, so the vector v = <5, -6> is heading towards SE.
Thus, option ( j ) is correct.
i.e. [tex]\sqrt{61},\:SE[/tex]

The required coordinates of Amy's position are (1.00, 1.73).
Amys walk 2 miles 60° northeast from her house. Vector coordinates to be determined.
Coordinate is defined as the abscissa and ordinate of the x-axis and y-axis respectively.
Amy walk 2 miles on 60° northeast, from origin.
x coordinate = 2cos60
= 2 * 1/2
= 1
y coordinate = 2sin60
= 2*√3/2
= 1.73
Thus, the required coordinates of Amy's position are (1.00, 1.73).

write the x and y coordinate (in the second and third column, respectively) of dilation of quadrilateral ABCD with vertices A(1,1), B(2,2), C(4,1) and d(2,-1). Use a scale factor of 2
Answer:
The coordinates of the dillated vertices are [tex]A'(x,y) = (2,2)[/tex], [tex]B'(x,y) = (4,4)[/tex], [tex]C'(x,y) = (8,2)[/tex] and [tex]D'(x,y) = (4,-2)[/tex].
Step-by-step explanation:
From Linear Algebra, we define dilation by the following equation:
[tex]P'(x,y) = O(x,y) + k\cdot [P(x,y)-O(x,y)][/tex] (1)
Where:
[tex]O(x,y)[/tex] - Center of dilation, dimensionless.
[tex]P(x,y)[/tex] - Original point, dimensionless.
[tex]k[/tex] - Scale factor, dimensionless.
[tex]P'(x,y)[/tex] - Dilated point, dimensionless.
If we know that [tex]O(x,y) = (0, 0)[/tex], [tex]k = 2[/tex], [tex]A(x,y) = (1,1)[/tex], [tex]B(x,y) = (2,2)[/tex], [tex]C(x,y) = (4,1)[/tex] and [tex]D(x,y) = (2,-1)[/tex], then the dilated points are, respectively:
Point A
[tex]A'(x,y) = O(x,y) + k\cdot [A(x,y)-O(x,y)][/tex] (2)
[tex]A'(x,y) = (0,0) + 2\cdot [(1,1)-(0,0)][/tex]
[tex]A'(x,y) = (2,2)[/tex]
Point B
[tex]B'(x,y) = O(x,y) + k\cdot [B(x,y)-O(x,y)][/tex] (3)
[tex]B'(x,y) = (0,0) + 2\cdot [(2,2)-(0,0)][/tex]
[tex]B'(x,y) = (4,4)[/tex]
Point C
[tex]C'(x,y) = O(x,y) + k\cdot [C(x,y)-O(x,y)][/tex]
[tex]C'(x,y) = (0,0) + 2\cdot [(4,1)-(0,0)][/tex]
[tex]C'(x,y) = (8,2)[/tex]
Point D
[tex]D'(x,y) = O(x,y) + k\cdot [D(x,y)-O(x,y)][/tex]
[tex]D'(x,y) = (0,0) + 2\cdot [(2,-1)-(0,0)][/tex]
[tex]D'(x,y) = (4,-2)[/tex]
The coordinates of the dillated vertices are [tex]A'(x,y) = (2,2)[/tex], [tex]B'(x,y) = (4,4)[/tex], [tex]C'(x,y) = (8,2)[/tex] and [tex]D'(x,y) = (4,-2)[/tex].

Gia researches online that her car is worth $3,000. She hopes to sell it for 85% of that value, but she wants to get at least 70%. She ends up selling it for $1,800. Did she get what she wanted? (Give both equations and solutions. Then answer the question of did she get what she wanted)
Answer:
she did not get at least 2100 and definitely not 85% of the worth
Step-by-step explanation:
3000*0.85=2550
3000*0.7=2100
Answer:
Gia hoped to sell it for $2,550, but wanted at least $2,100. Because it sold for $1,800, she did not get what she hoped and/or wanted.
Step-by-step explanation:
85% of $3,000 can be solved by moving the decimal two places to the left and multiplying: 85.0% becomes 0.85. So, we multiply 0.85x3,000=$2,550.
We do the same thing to figure out 70% of $3,000. Again, solving it by moving the decimal two places to the left and multiplying: 70.0% becomes 0.70. So, we multiply 0.70x3,000=$2,100.

A student borrows a total of $5400 in student loan from two lenders. Bank One charges 4.3% simple
interest and Bank Two charges 5.9% simple interest. She is not required to pay off the principal for 3
years. However, at the end of three years, she will owe a total of $888.60 for interest from both loans.
How much did she borrow from Bank One?
non
9514 1404 393
Answer:
$1400
Step-by-step explanation:
Let x represent the amount borrowed from Bank 1. For each loan, the interest is given by I=Prt, where P is the principal borrowed at rate r for t years.
Then the total interest over 3 years is ...
3(4.3%·x +5.9%(5400 -x)) = 888.60
-1.6%·x +318.60 = 296.20 . . . . . . . . . . . divide by 3, simplify
-1.6%·x = -22.40 . . . . . . . . . . . subtract 318.60
x = 22.40/0.016 = 1400
The student borrowed $1400 from Bank 1.

Will the border line of the graph of y < - x2 + 4x + 5 be a solid line or a broken
line?
Is the point (0,0) part of the solution of y<-x2 +4x+5
Step-by-step explanation:
When the inequality uses < or >, it is a broken line.
For the point (0, 0) it means that x = 0 and y = 0.
Since (0) < (0)² + 4(0) + 5 is true, the point is part of the solution.
Yes, the point (0,0) is part of the solution of y < - x² + 4x + 5.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
To determine the border line of the graph of y < - x² + 4x + 5
A broken line results from the inequality using < or >.
x and y are both equal to zero at the coordinates (0, 0).
Substitute the values of x = 0 nad y = 0 in the inequality y < - x² + 4x + 5
So, (0) < (0)² + 4(0) + 5
Since (0) < (0)² + 4(0) + 5 is valid,
Thus, the coordinates (0, 0) are part of the solution.

Ronnie records the number of chirps per minute (x) that crickets make at different temperatures(Y ) in degree Fahrenheit. he determines that the association is linear and that the line of best fit is Y=1/6x+60.what is the interpretation of the slope and y intercept of this question?
Answer:
Step-by-step explanation:
Given
[tex]y = \frac{1}{6}x + 60[/tex]
Required
Interpret the slope and y intercept
The general form of an equation is:
[tex]y = mx + b[/tex]
Where
[tex]m=slope[/tex]
[tex]b = y\ intercept[/tex]
By comparison
[tex]m = \frac{1}{6}[/tex]
[tex]b = 60[/tex]
Interpretation:
Slope represents rate and y intercept represents the number of chirps at time 0.
So, the interpretations are:
Slope: The cricket chirps at a rate of [tex]\frac{1}{6}[/tex] chirps per minute
y intercept: The initial number of chirps is 60
