The distance between the points (3, 6) and (8, -1)
[tex]d=8.6[/tex]Step-by-step explanation:
Given the points
(3, 6)(8, -1)Finding the distance between the points (3, 6) and (8, -1)
(x₁, y₁) = (3, 6)
(x₂, y₂) = (8, -1)
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(8-3\right)^2+\left(-1-6\right)^2}[/tex]
[tex]=\sqrt{5^2+7^2}[/tex]
[tex]=\sqrt{25+49}[/tex]
[tex]=\sqrt{74}[/tex]
[tex]d=8.6[/tex]
Thus, the distance between the points (3, 6) and (8, -1)

The length of a rectangle is 10 inches longer than its width. If the area of the rectangle is 144 square inches, what are its dimensions? Write an equation is standard form that can be used to find the dimensions.
Answer:
L= 18 in
W= 8 in
Step-by-step explanation:
Step one:
The length of a rectangle is 10 inches longer than its width
let the width be x
so the lenght is x+10
the area of the rectangle is 144 square inches
Step two:
[tex]Area= L*W\\\\144=x(x+10)\\\\144=x^2+10x\\\\x^2+10x-144=0[/tex]
the factors for the quadratic expression is
18 and -8
[tex]x^2+18x-8x-144=0\\\\x(x+18)-8(x+18)=0\\\\x-8=0\\\\x=8\\\\x+18=0\\\\x=-18[/tex]
the width is 8 in
the length is 8+10= 18 in
From the equation, the length is 18 inches and the width is 8 inches.
Let width = w
Since the length of a rectangle is 10 inches longer than its width, the length will be w+10.
Area = 144 inches²
Area = Length × Width
w(w + 10) = 144
w² + 10w = 144
w² + 18w - 8w - 144 = 0
w(w + 18) - 8(w + 18) = 0
(w - 8) = 0
w = 0 + 8 = 8
Length = w + 10 = 8 + 10 = 18

Alana buys 3 pounds of potatoes for $2.82. What is the unit
price of the potatoes?
A. $9.40 per pound
B. $8.46 per pound
C. $1.41 per pound
D. $0.94 per pound
Answer:
D. $0.94 per pound
Step-by-step explanation:
To find how much each potato costs, we have to do 2.82/3
This is equal to $0.94, so $0.94 per pound!
Check:
With each potato being $0.94 ( according to my calculations ), 3 potatoes should be $2.82. So, $0.94 * 3 should be equal to $2.82.
3 * 0.94 = 2.82 Correct!

e) 340 people participated in a conference. If the ratio of ladies and gentleman is
3:2, find the number of ladies and gentlemen in the conference.
Answer:
There were 204 ladies and 136 gentlemen in the conference
Step-by-step explanation:
Let's set the variables:
L = number of ladies in the conference
G = number of gentlemen in the conference
We know 340 people participated in the conference, thus:
L + G = 340 [1]
We are also given the ratio of ladies and gentleman as 3:2, thus:
L/G = 3/2
Cross-multiplying:
2L = 3G [2]
From [1]:
L = 340 - G
Substituting in [2]:
2(340 - G) = 3G
Operating:
680 - 2G = 3G
5G = 680
G = 680/5 = 136
G = 136
L = 340 - 136 = 204
L = 204
There were 204 ladies and 136 gentlemen in the conference

Rewrite equations:

Step: Solve−2x+y=3for y:
−2x+y=3
−2x+y+2x=3+2x(Add 2x to both sides)
y=2x+3
Step: Substitute2x+3foryin3x−2y=5:
3x−2y=5
3x−2(2x+3)=5

The inverse of [tex]f(x)=8x+10[/tex] is [tex]\mathbf{f^{-1}(x)=\frac{x-10}{8}}[/tex]
Step-by-step explanation:
[tex]f(x)=8x+10[/tex]
We need to find inverse of the function.
For finding inverse of function,
let [tex]y=8x+10[/tex]
Now, solving to find value of x
Subtracting 10 on both sides
[tex]y-10=8x+10-10\\y-10=8x[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}=\frac{y-10}{8} \\x=\frac{y-10}{8}[/tex]
Now replace y with x and x with [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(x)=\frac{x-10}{8}[/tex]
So, the inverse of [tex]f(x)=8x+10[/tex] is [tex]\mathbf{f^{-1}(x)=\frac{x-10}{8}}[/tex]
Answer:
The answer is [tex]f^(-1)(x)= (x^(2) - 10)/(8), x > =0[/tex]

Answer:
EF = DE = 44FG = DG = 36FH = DF = 31Step-by-step explanation:
Since EH is the perpendicular bisector of DF, ∆DEF is isosceles and sides DE and EF have the same length.
DE = EF
(9x -1) = (7x +9)
2x = 10 . . . . . . . add 1-7x
x = 5 . . . . . . . . . divide by 2
__
Similarly, marked sides GD and GF are the same length, so ...
GD = GF
(10y -4) = (7y +8)
3y = 12 . . . . . . . . . . add 4-7y
y = 4 . . . . . . . . . divide by 3
__
Now, we have what we need to calculate the side lengths.
EF = 7x+9 = 7·5 +9 = 44
DE = 9x-1 = 9·4 -1 = 44
FG = 7y+8 = 7·4 +8 = 36
DG = 10y-4 = 10·4 -4 = 36
FH = 3x+4y = 3·5 +4·4 = 31
DF = FH = 31
on the following unit circle, \thetaθtheta is in radians. a unit circle with an angle from the positive x-axis to a ray labeled theta. the point where the ray intersects the circle is labeled 0.54, 0.84 and is in the first quadrant.
The value of the trigonometry are sin(Π-Ɵ) = 0.84 and sin(Π + Ɵ) = -0.84
According to the question, there is a circle whose radius is 1 and the ray intersects the circle at point (0.54, 0.84).
We need to find the trigonometric values, that is
sin(Π-Ɵ) = sin(Ɵ) as we know that when the angle is in third quadrant sin is positive.
sin(Π+Ɵ) = -sin(Ɵ) as we know that when the angle is in fourth quadrant sin is negative.
Also note that, sinƟ = perpendicular/hypotenuse
Perpendicular = 0.84 as the perpendicular length will be equal to the length of the y-axis
Hypotenuse = 1 as the hypotenuse will be the radius of the circle which is formed by the ray.
Thus, sinƟ = 0.84/1 = 0.84
Hence, sin(Π-Ɵ) = 0.84
And sin(Π+Ɵ) = -0.84
