4x-5 /6- 2x-1 /6 = 2/3
Answer:
x = [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Given
4x - [tex]\frac{5}{6}[/tex] - 2x - [tex]\frac{1}{6}[/tex] = [tex]\frac{2}{3}[/tex]
Multiply through by 6 to clear the fractions
24x - 5 - 12x - 1 = 4
12x - 6 = 4 ( add 6 to both sides )
12x = 10 ( divide both sides by 12 )
x = [tex]\frac{10}{12}[/tex] = [tex]\frac{5}{6}[/tex]
triangular park ABC has sides 3 m, 5 m, and 6 m. a gardener ravi wants to put a fence all around it and also plant grass inside. how much area does he need to plant?

What is the center and radius of the circle? (x-4)^2 + (y-7)^2 =49
Answer:
The center of circle is: (-7,4) and Radius is 7 units
or (-4,7) and Radius is 7 units
We have to compare the given equation of circle with standard equation of circle
Given equation is:
2nd pic
down below
Standard equation of circle is:
3rd pic
down below
Here
h and k are coordinates of center of circle
So,
comparing
1st pic
down below
Hence,
The center of circle is: (-7,4) and Radius is 7 units
Keywords: Circle, radius
Answer:
The center is ( 4 , 7)The radius is 7Step-by-step explanation:
First expand the equation
That's
( x - 4)² + ( y - 7)² = 49
x² - 8x + 16 + y² - 14y + 49 - 49 = 0
x² + y² - 8x - 14y + 16 = 0
Comparing with the general equation of a circle
x² + y² + 2gx + 2fy + c = 0
2g = - 8 2f = - 14
g = - 4 f = - 7 c = 16
Center of a circle is ( - g , - f)
( --4 , --7)
Which is ( 4 , 7)
The radius of the circle is given by
r = √g² + f² - c
Where r is the radius
r = √ (-4)² + (-7)² - 16
= √16 + 49 - 16
= √49
= 7Hope this helps you

Six friends went to a restaurant and agreed to share the bill equally. However, two people forgot their wallets so the other four friends' portions of the bill went up by $7 each. How many dollars was the total bill?
Answer:
The total bill was $84
Step-by-step explanation:
Ok so we know a few things, we know that the total cost of the bill is divisible by both 6 and 4, and we know that if we call the total cost of the bill x and the amount each person would pay if it was divided for 6 people y we can write these equations:
[tex]\frac{x}{6}=y[/tex]
[tex]\frac{x}{4}=y+7[/tex]
Now we can substitute the first equation into the second and solve for x
[tex]\frac{x}{4}=\frac{x}{6}+7\\\frac{x}{4}-\frac{x}{6}=7\\\frac{x}{12}=7\\x=7*12=84[/tex]
Therefore, the total bill was $84
Let f(x) = 1/x . Find the number b such that the average rate of change of f on the interval [2, b] is − 1/8
Answer:
b=4
Step-by-step explanation:
So, we have the function [tex]f(x)=1/x[/tex]. We need to find b such that the average rate of change or the slope is -1/8 between the intervel [2, b]. First, let's find f(2).
f(2) = 1/(2) = 1/2
So, we have the point (2, 1/2)
At point b, f(b) = 1/b.
Let's plug this into the slope formula:
[tex]\frac{y_2-y_1}{x_2-x_1}=\frac{.5-\frac{1}{b} }{2-b} =-1/8[/tex]
Now, we just need to solve for b. First, let's multiply both the numerator and denominator by b (to get rid of the annoying fraction in the numerator).
[tex]\frac{.5b-1}{2b-b^2} =\frac{-1}{8}[/tex]
Now, cross multiply.
[tex]4b-8=b^2-2b[/tex]
[tex]b^2-6b+8=0[/tex]
Solve for b. Factor using the numbers -4 and -2.
[tex]=(b-4)(b-2)=0[/tex]
Thus, b=4 or b=2.
However, b=2 is not a possible solution since the interval [2,2] means nothing. Thus, b=4.
We want to find an interval such that the given equation, f(x) = 1/x, has an average rate of change of -1/8 in that interval.
We will see that the interval is [2, 4]
-------------------------------
For a function f(x), the average rate of change in the interval [a, b] is given by:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
Here we have:
[tex]f(x) = 1/x[/tex]
And the interval is [2, b] such that r in that interval is -1/8, so we need to solve:
[tex]r = -1/8 = \frac{f(b) - f(2)}{b - 2} = \frac{1/b - 1/2}{b - 2}[/tex]
We can rewrite it to:
[tex]-1/8 *(b - 2)= 1/b - 1/2\\\\-1/8 *(b - 2)= 2/2b - b/2b = (2 - b)/2b = -(b - 2)/2b[/tex]
Now we can remove the term (b - 2) because it appears on both sides, so we get:
[tex]-1/8 = -1/2b\\1/8 = 1/2b\\2/8 = 1/b\\1/4 = 1/b\\b = 4[/tex]
Then we found that b must be equal to 4, so the interval is [2, 4]

Identify the sequence graphed below and the average rate of change from n = 0 to n = 3 . (2, 10) (3, 5) (4, 2.5) (5, 1.25)
A) a_n=8(1/2)^(n-2); average rate of change is -3
B) a_n=10(1/2)^(n-2); average rate of change is -(35/3)
C) a_n=8(1/2); average rate of change is 3
D) a_n=10(1/2)^(n-2); average rate of change is 35/3
Answer: Choice B
a_n = 10(1/2)^(n-2) is the nth term
average rate of change = -35/3
=======================================================
Explanation:
Each time x increases by 1, y is cut in half. For instance, going from (2,10) to (3,5) shows this.
If we want to go in reverse, decreasing x by 1 will double the y value. So (1,20) is another point and (0,40) is another. We'll be using (0,40) and (3,5) because we want the average rate of change from x = 0 to x = 3. I'm using x in place of n here.
Use the slope formula to find the slope of the line through (0,40) and (3,5)
m = (y2-y1)/(x2-x1)
m = (5-40)/(3-0)
m = -35/3
The negative slope means the line goes downhill as you read it from left to right. The average rate of change from n = 0 to n = 3 is -35/3
The nth term of this geometric sequence is 20(1/2)^(n-1) since 20 is the first term (corresponds to n = 1) and 1/2 is the common ratio. Your teacher has done a bit of algebraic manipulation to change the n-1 into n-2. This means the 20 has to change to 10 to counterbalance.
In other words, 20(1/2)^(n-1) is equivalent to 10(1/2)^(n-2) when n starts at n = 1.

A garden has an area of 264ft^2. Its length is 10 ft more than its width. What are the dimensions of the garden?
Answer:
Length = 22 ftWidth = 12 ftStep-by-step explanation:
Let length of the garden be ' x + 10 '
Let breath of the garden be ' x '
Area of the garden = 264 ft²
Now, let's find the breath of the garden 'x'
[tex]x(x + 10) = 264[/tex]
Distribute X through the parentheses
[tex] {x}^{2} + 10x = 264[/tex]
Move constant to left and change its sign
[tex] {x}^{2} + 10x - 264 = 0[/tex]
Write 10x as a difference
[tex] {x}^{2} + 22x - 12x - 264 = 0[/tex]
Factor out X from the expression
[tex]x(x + 22) - 12x - 264 = 0[/tex]
Factor out -12 from the expression
[tex]x(x + 22) - 12(x + 22) = 0[/tex]
Factor out X +22 from the expression
[tex](x + 22)(x - 12) = 0[/tex]
When the products of factors equals to 0 , at least one factor is 0
[tex]x + 22 = 0[/tex]
[tex]x - 12 = 0[/tex]
Solve for X
[tex]x + 22 = 0[/tex]
[tex]x = 0 - 22[/tex]
[tex]x = - 22[/tex]
Again,
[tex]x - 12 = 0[/tex]
[tex]x = 0 + 12[/tex]
[tex]x = 12[/tex]
(The dimensions can't be negative. )
So, width = 12 ft
Now, let's find the length of the garden ' X + 10 '
[tex]x + 10[/tex]
Plug the value of X
[tex]12 + 10[/tex]
Calculate the sum
[tex] = 22 \: ft[/tex]
Therefore,
Length = 22 ftWidth = 12 ftHope this helps..

The side y is across from the angle Y which is 68 degrees. Angle Y is next to both the hypotenuse (14 units) and adjacent to the side XY (5 units). If we are finding side y, we need to use one of the trig ratios that relates the angle Y to the side across from it. That would be either the sin of Y which is the side opposite y) over the hypotenuse (14) or the tan of Y which is the side opposite over the side adjacent. Either one will get you the side lengths within a tenth or hundredth of each other. Let's do both, just because. First the sine:
[tex]sin(68)=\frac{y}{14}[/tex] and
14sin(68) = y so
y = 12.98 and rounded to the nearest tenth is 13.0
Now the tangent:
[tex]tan(68)=\frac{y}{5}[/tex] and
5tan(68) = y so
y = 12.37 and rounded to the nearest tenth is 12.4.
As an integer, your answer would be 13; as a decimal it would be the 12.4
Apparently, either is fine.

Answer:
B. 2/3
Step-by-step explanation:
To solve this we have to take into account this axioms:
- The total probability is always equal to 1.
- The probability of a randomly selected point being inside the circle is equal to one minus the probability of being outside the circle.
Then, if the probabilities are proportional to the area, we have 1/3 probability of selecting a point inside a circle and (1-1/3)=2/3 probability of selecting a point that is outside the circle.
Then, the probabilty that a random selected point inside the square (the total probability space) and outside the circle is 2/3.

The function with the greatest output is graph B
===========================================================
Explanation:
As the graphs head to the right, they go up forever. However, the growth rate (how fast they go upward) varies. The red straight line (line A) goes up the slowest. The growth rate is the same throughout the entire function. The rate is the slope of the line. In contrast, the purple curve B goes up the fastest as it has the steepest increase among the four graphs. The graph steadily gets steeper as you move to the right.
The exponential graph will grow the fastest compared to a linear one or parabolic one. Graphs B and C are exponential, where graph B has a steeper curve compared to graph C.
