2. Consider the line
y = 3/5x -8
What is the
slope of the line perpendicular to this line?
Answers
Answer:
The slope of the perpendicular line is [tex]-\frac{5}{3}[/tex]
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1That means to find the slope of a perpendicular line to a given line, reciprocal its value, and reverse its signEx: If the slope of a line is [tex]\frac{1}{3}[/tex], then the slope of the line perpendicular to it is -3Let us solve the question
∵ The equation of a line is y = [tex]\frac{3}{5}[/tex] x - 8
→ The form of the equation is y = m x + b, where m is the slope
∴ The slope of the line is [tex]\frac{3}{5}[/tex]
→ To find the slope of the line perpendicular to it reciprocal it and
reverse its sign
∵ The reciprocal of [tex]\frac{3}{5}[/tex] is [tex]\frac{5}{3}[/tex]
→ Change its sign from positive to negative
∴ The slope of the perpendicular line is [tex]-\frac{5}{3}[/tex]

Answer:
One solution
Step-by-step explanation:
Combine like terms and simplify.
20z - 5 - 12z = 10z + 8
⇒ z(20 - 12) - 5 = 10z + 8
⇒ z(8) - 5 = 10z + 8
⇒ 8z - 5 = 10z + 8
Subtract 8z both sides.
⇒ 8z - 8z - 5 = 10z + 8 - 8z
⇒ -5 = 2z + 8
Subtract 8 both sides.
⇒ -5 - 8 = 2z + 8 - 8
⇒ -13 = 2z
⇒ -13/2 = 2z/2
⇒ -6.5 = z
Thus, there is 1 solution.

Answers
Question :-
The Length of a Rectangular Parking Area is Two times the Width. The Perimeter is 90 yards . Find the Length and Width of the Parking Area .Answer :-
Length of Parking Area is 15 yards .Width of Parking Area is 30 yards .Explanation :-
As per the provided information in the given question, we have been given that the Length of a Rectangular Parking Area is Two times the Width . The Perimeter is given as 90 yards . And, we have been asked to calculate the Length and the Width .
Let the Values be like :-
Length = xBreadth = 2xNow, for calculating the Length & Width , we will use the Formula :-
[tex] \bigstar \: \: \boxed{ \sf{ \: Perimeter \: _{Rectangle} \: = \: 2 \times [ \: Length + Breadth \: ] \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf{Perimeter \: _{Rectangle} \: = \: 2 \: \times \: [ \: Length \: + \: Breadth \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf { 90 \: = \: 2 \: \times \: [ \: x \: + \: 2x \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 2 \: \times \: [ \: 3x \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 2 \: \times \: 3x } [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 6x } [/tex]
[tex] \longmapsto \: \: \: \sf {x \: = \: \dfrac { \: 90 \: }{6}} [/tex]
[tex] \longmapsto \: \: \textbf {\textsf{ x \: = \: 15}} [/tex]
Therefore :-
[tex] \Longrightarrow \: [/tex] Length = x = 15 yards
[tex] \Longrightarrow \: [/tex] Breadth = 2x = 2 × 15 = 30 yards

Breadth = 2x
Now, we will use the Formula :-
Perimeter = 2(L + B)
By Substituting the given values in the above Formula :-
Perimeter = 2(L + B)
90= 2(x + 2x)
90= 2(3x)
45 = 3x
x = 15

find the slope of the line that passes through the points A(-6,2) and B(5,-1).
A 3/11
B -3/11
C -1
D -11/3
Answers
Answer:
[tex]\boxed{\sf{m=-\dfrac{3}{11} }}[/tex]
Step-by-step explanation:
You simply need to use a slope formula that passes through the points in order to solve this problem.
Slope:
[tex]\sf{\dfrac{Y_2-Y_1}{X_2-X_1}=\dfrac{RISE}{RUN} }[/tex]
y2=(-1)
y1=2
x2=5
x1=(-6)
Rewrite the problem down.
[tex]\sf{\dfrac{-1-2}{5-(-6)}=\dfrac{-1-2}{5+6}=\dfrac{-3}{11}=\boxed{\sf{-\dfrac{3}{11} }}}[/tex]
-3/11
Therefore, the slope is -3/11, which is our answer.

Answers
Part (a)
The locus is the set of points that satisfy the given conditions. Namely that the point P needs to be 1 unit from the line given.
Think of a median along a highway. Then imagine the two shoulders of the road. The locus describes the two parallel lines that are to this given median. In other words, the median is y = x+2 and the road shoulders are unknown for now.
Though we do know that parallel lines have equal slopes (but different y intercepts).
Therefore, the answers to the next section will be of the form y = x+k for some real number k.
=============================================================
Part (b)
Use your favorite graphing tool to plot y = x+2. I recommend GeoGebra since I use it all the time, and it's what I used to make the drawing below. Desmos is another tool you can use. Both are free.
Note that point A(0,2) is on the line y = x+2. The line perpendicular to y = x+2 and goes through (0,2) is y = -x+2. From here, plot a circle centered at (0,2) with radius 1. The equation of this circle is x^2 + (y-2)^2 = 1
The intersection points of the circle and y = -x+2 will provide starting points, so to speak, for the two shoulder lines I mentioned in part (a).
The approximate locations of those points are:
B = (0.71, 1.29)
C = (-0.71, 2.71)
From here, it shouldn't be too hard to find the y = mx+b forms of the locus lines. Let me know if you need help with that, or if you need me to check your answers.
Side note: Why is it called a locus? I'm not sure, but my gut feeling tells me it has to do with the insects of a similar sounding name (locus the math term and locust the insect). Imagine millions of them forming various shapes in the sky, similar to how many points are used in the 2D plane to create various curves.

Sum of the interior angles of any triangle equal 180° .
So ;
A + B + ECB = 180°
A = B = μ
So : 2μ + ECB = 180°
→ ECB = 180° - 2μ
_________________________________
ECF + ECB = 180°
ECF + 180° - 2μ = 180°
ECF = 180° - 180° + 2μ
ECF = 2μ
_________________________________
∆ ADE :
A + D + E = 180°
μ + 90° + E = 180°
E = 180° - 90° - μ
E = 90° - μ

AED + AEF = 180°
90° - μ + AEF = 180°
AEF = 180° - 90° + μ

Answers
Answer: The width would be 5 and the length would be 16
Step-by-step explanation:

On the graph of f(x)=sinx and the interval [2π,4π), for what value of x does f(x) achieve a minimum?
Answers
Answer:
Step-by-step explanation:
The minimum value of sinx is -1 when x = 3π/2, 7π/2, ...
In [2π, 4π), x = 7π/2
The function f(x)=sin(x) achieves its minimum value of -1 at x=3π.
The function f(x)=sin(x) is a periodic function with a period of 2π, meaning it repeats every 2π units. Within the interval [2π,4π), which is one period of the function, the minimum value of sin(x) occurs at x=3π.
This is because at x=3π, the sine function reaches its minimum value of -1. As you move further away from 3π, the sine function starts increasing again.
So, within the interval [2π,4π), the function f(x)=sin(x) achieves its minimum value of -1 at x=3π.

Identify the mistake and write down the correct answe 2/5 + 1/3 = 3/8
Answers
Answer:
The mistake is that the denominators are not the same in these fractions so you cannot add them yet. So, you would have to change the denominators to be the same before adding. The denominators I chose is 15, 2/5 times 3 which is equal to 6/15 and 1/3 times 5 which is equal to 5/15. Now, we can add 6/15 and 5/15 which is equal to 11/15!
