) Find the value of k so that 5x + ky = 20 makes an angle of 60° with x-axis.
Find the value of k so that 4x + ky = 15 makes an angle of 60° with y-axis.
Answer:
k = - 5/√3 = - (5√3)/3
Step-by-step explanation:
5x + ky = 20
y = (- 5/k) * x + (20/k)
Line equation: y = mx + b m: slope m = - 5/k
60° with x-axis (suppose it's positive x axis): slope m = tan 60° = √3
- 5/k = √3
k = - 5/√3 = - (5√3)/3

What is the solution set to the following system?
x+y=3
(x² + y² = 9
Answer:
The solutions are 0 and 3
Step-by-step explanation:
x = 3-y
((3-y)^2+y^2)=9
=(y^2-6y+9)+y^2) = 9
= 2y^2 - 6y +9 -9 =0
=2y^2 -6y=0
= y*(2y -6) = 0
y1=0 y2=3
The solution of the system x + y = 3 and x² + y² = 9 is y = 0 and y = 3.
What is equation?A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given:
x + y = 3
x² + y² = 9
Solve the equation as shown below,
x = 3 - y
Put this value of x in the second equation,
(3 - y)² + y² = 9
y² + 9 - 6y + y² = 9
2y² - 6y = 0
Solve the quadratic equation,
2y (y - 3)
y = 0 and y = 3

If line segment AB represents 25%, what is the length of a line segment that is 100%?
If I am correctly understanding the question, I think the length of the line segment would be 4AB
Step-by-step explanation:
25% = 1/4
AB = 1/4
100% = 4/4
AB*4 = 4AB
Multiply AB by 4 to find the value that 100% would equal, resulting in 4AB.

A rocket is fired upward from the ground with an initial velocity of feet per second. Neglecting air resistance, the height of the rocket at any time t can be described in feet by the polynomial . Find the height of the rocket at .
Complete question is;
A projectile is fired upward from the ground with a velocity of 250 feet
per second. Neglecting air resistance, the height of the projectile in feet at
any time t, in seconds, can be described by the polynomial function P(t) = -16t² + 250t. Find the height at t = 4 seconds
Answer:
744 ft
Step-by-step explanation:
We are told that the height of the rocket is represented by the polynomial P(t) = -16t² + 250t
Where t is time in seconds.
Now, we want to Find the height at t = 4 seconds
Thus;
P(4) = -16(4²) + 250(4)
P(4) = -256 + 1000
P(4) = 744 ft

Angle 1 = 78°
Angle 2 = 78°
Angle 3 = 24°
Step-by-step explanation:
The given triangle is isosceles triangle because AB = BC
We know that sum of angles of triangle = 180°
and Isosceles sides have same angles.
We have Angle 1 = (6x+6)°
Angle 2 = (6x+6)°
Angle 3= (2x)°
We can write
[tex](6x+6)^{\circ}+(6x+6)^{\circ}+2x^{\circ}=180^{\circ}[/tex]
Solving this equation we can find value of x
[tex](6x+6)^{\circ}+(6x+6)^{\circ}+2x^{\circ}=180^{\circ}\\6x+6+6x+6+2x=180\\14x+12=180\\14x=180-12\\14x=168\\x=\frac{168}{14}\\x=12[/tex]
So, the value of x = 12
Now finding angles
Angle 1 = (6x+6)° = 6(12)+6 = 72+6 = 78°
Angle 2 = (6x+6)°= 6(12)+6 = 72+6 = 78°
Angle 3= (2x)°= 2(12) = 24°

Step-by-step explanation:
On a particular airline, checked bags can weigh no more than 50 pounds.
Jennifer packed 32 pounds of clothes and five identical gifts (x) in a suitcase that weighs 8 pounds when empty.
Write an inequality to represent the total weight of the suitcase so it does not exceed the maximum weight.
Answer:
40 + 5x ≤ 50
Step-by-step explanation:
Inequalities
The maximum weight allowed for checked bags on a particular airline is 50 pounds.
Jennifer has already used up to 32 pounds of clothes and the empty suitcase weighs 8 pounds. This makes a weight of 40 pounds already used.
If five identical gifts of x pounds each are to be included in the suitcase, the total weight is 40 + 5x. And that weight cannot exceed 50 pounds, thus:
40 + 5x ≤ 50
That is the inequality to represent the situation.

On a coordinate plane, a vector has an origin (0, 0) and terminal point (8, 7).
Which description of the vector shown is correct?
The magnitude is 15, and the direction angle is approximately 49°.
The magnitude is 15, and the direction angle is approximately 41°.
The magnitude is StartRoot 113 EndRoot, and the direction angle is approximately 49°.
The magnitude is StartRoot 113 EndRoot, and the direction angle is approximately 41°.
Answer:
D. The magnitude is StartRoot 113 EndRoot, and the direction angle is approximately 41°.
Step-by-step explanation:
The correct description of the vector is that the magnitude is √(113) and therefore the direction angle is 41°.
What is the magnitude of the vector?The magnitude of the vector is the length of the vector which can be calculated from the coordinate of its endpoint.
Let (x1,y1) and (x2,y2) are the coordinate of the two endpoints of a vector V.
The magnitude of the vector= |V|= √(y2-y1)²+(x2-x1)²
We have,
Origin of vector = (0,0)
And,
Terminal point = (8, 7)
Here,
a = 8 and b = 7
Now,
To find the magnitude of the vector, we are going to use;
Formula, |v| = √(a² + b² )
|v| = √(8² + 7² )
|v| = √(64 + 49)
|v| = √113
So, the magnitude of the vector is √113.
Now,
Direction angle is find out using ;
Θ = tan ⁻¹ (b / a)
So, Here,
Θ = Angle Direction
Now,
Θ = tan ⁻¹ (7 / 8)
Θ = 41°
Therefore, the proper description of the vector is that the magnitude is √(113) and also the direction angle is 41°.
