What is the next term of the geometric sequence?
40/27,20/9,10/3
Answer:
5
Step-by-step explanation:
By trial and error, we see that we can multiply by 3/2 every time to continue the sequence! So multiplying 10/3 by 3/2, we get 5. So 5 is the next term of the geometric sequence.
Explain why the solution to 3r=2 must be less than 1
Answer:
see below
Step-by-step explanation:
3r=2
We know that r must be less than 1 because we are multiplying 3 by a number and getting 2
Taking a larger number and multiplying by r and getting a smaller number means the number must be less than 1
Divide each side by 3
3r/3 = 2/3
r = 2/3
2/3 is less than 1

What is the solution of the equation 92x = 6? Round your answer to the nearest ten-thousandth.
Answer:
The solution of the equation 92x = 6 is x= 0.065
Step-by-step explanation:
We need to solve the equation 92x = 6 and find the value of x.
Given: 92x = 6
Divide both sides of the equation with 92
92x/92 = 6/92
x = 3/46
x = 0.065
So, the solution of the equation 92x = 6 is x= 0.065

3[–x + (2 x + 1)] = x – 1 solve for x
Hey there! :)
3[-x + (2x + 1)] = x - 1
Simplify the parenthesis!
3[-x + 2x + 1] =x - 1
Add like terms.
3[x + 1] = x - 1
Simplify!
3x + 3 = x - 1
Subtract 1x from both sides.
3x + 3 - 1x = x - 1 - 1x
Simplify.
2x + 3 = -1
Subtract 3 from both sides.
2x = -4
Divide both sides by 2.
2x ÷ 2 = -4 ÷ 2
Simplify.
x = -2

8. Suppose the curve y = x4 + ax3 + bx2 + cx + d has a tangent line when
x = 0 with equation y = 2x + 1, and a tangent line when x = 1 with equation
y= 2 – 3x. Find the values of a, b, c and d.
Answer:
a=1, b=-6, c=2, d=1
Step-by-step explanation:
You are given the function
[tex]y=x^4+ax^3+bx^2+cx+d[/tex]
Find the derivative:
[tex]y'=4x^3+3ax^2+2bx+c[/tex]
The curve has a tangent line when x = 0 with equation y = 2x + 1, so
[tex]y'(0)=2\\ \\y(0)=1[/tex]
Hence,
[tex]y'(0)=4\cdot 0^3+3a\cdot 0^2+2b\cdot 0+c=2\Rightarrow c=2\\ \\y(0)=0^4+a\cdot 0^3+b\cdot 0^2+2\cdot 0+d=1\Rightarrow d=1[/tex]
The curve has a tangent line when x = 1 with equation y = -3x + 2, so
[tex]y'(1)=-3\\ \\y(1)=-3+2=-1[/tex]
So,
[tex]y'(1)=4\cdot 1^3+3a\cdot 1^2+2b\cdot 1+c=4+3a+2b+2=-3\Rightarrow 3a+2b=-9\\ \\y(1)=1^4+a\cdot 1^3+b\cdot 1^2+2\cdot 1+d=1+a+b+2+1=-1\Rightarrow a+b=-5[/tex]
From the second equation, a=-5-b, substitute it into the first one:
[tex]3(-5-b)+2b=-9\\ \\-15-3b+2b=-9\\ \\-b=-9+15\\ \\-b=6\\ \\b=-6\\ \\a=-5-b=-5-(-6)=-5+6=1[/tex]

Which expression is equivalent to..? Assume
Answer:
The equivalent ratio of (3m⁻²n)⁻³/6mn⁻² = m⁵/2n
Step-by-step explanation:
Points to remember
Identities
xᵃ * xᵇ = x⁽ᵃ ⁺ ᵇ⁾
xᵃ/xᵇ = x⁽ᵃ ⁻ ᵇ⁾
(xᵃ)ᵇ = xᵃᵇ
x⁻ᵃ = 1/xᵃ
To find the equivalent ratio of (3m⁻²n)⁻³/6mn⁻²
By using identities,
(3m⁻²n)⁻³ = 3m⁶n⁻³
(3m⁻²n)⁻³/6mn⁻² = 3m⁶n⁻³/6mn⁻²
= 3m⁽⁶⁻¹⁾n⁽⁻³ ⁻ ⁻²⁾/6
= m⁵n⁻¹/2
= m⁵/2n
Therefore the equivalent ratio of (3m⁻²n)⁻³/6mn⁻² = m⁵/2n
The cost of performance tickets and beverages for a family of four can be modeled using the equation 4x + 12 = 48, where x
represents the cost of a ticket. How much is one ticket?
$3.00
$4.00
$9.00
$15.00
Answer:
C) $9.00
Step-by-step explanation:
You're trying to find the value of x. 4x + 12 = 48 Subtract 12 from both sides to get:4x = 36 Then, divide each side by 4 to get:x = 9For this case we have that the cost of a ticket is given by the variable "x". We have the following equation:
[tex]4x + 12 = 48[/tex]
By clearing "x" we have:
We subtract 12 on both sides of the equation:
[tex]4x = 48-12\\4x = 36[/tex]
Dividing between 4 on both sides of the equation:
[tex]x = \frac {36} {4}\\x = 9[/tex]
Then, a ticket costs $ 9.00

Find the output y, when input x is 6
Answer:
0
Step-by-step explanation:
Final answer:
To find the output y for an input x of 6, assuming a linear relationship based on a derivative example provided, we use the equation y = 3x + 6. Substituting x with 6 gives us y = 24.
Explanation:
The question requires us to find the output y when the input x is 6. The equation provided in the excerpts can be interpreted in many ways due to lack of clarity in the given information. However, a linear function example is given by dy/dx = 6+3x, where the derivative suggests an initial value of 6 increasing by 3 with each unit increase in x. If we assume a linear relationship y = mx + b, we can use the pattern in the derivative example and set the slope m as 3 and the y-intercept b as 6. This yields the equation y = 3x + 6. When x is 6, the output y is calculated as y = 3(6) + 6 = 18 + 6 = 24.
Remember, the equation provided in the tutorial only applies if we assume a linear relationship based on the derivative example mentioned. It is important to have the exact equation or context to provide the precise output y.

Writing an Equation Given Two Points on the Line
Write the equation of the line that passes through the points (7,-4) and (-1,3), first in point-slope form, and then in
slope-intercept form.
The slope of the line is
When the point (7.-4) is used, the point-slope form of the line is
The slope-intercept form of the line is
Answer:
[tex]\text{The slope:}\ m=-\dfrac{7}{8}\\\\\text{The point-slope form:}\ y+4=-\dfrac{7}{8}(x-7)\\\\\text{The slope-intercept form:}\ y=-\dfrac{7}{8}x+\dfrac{17}{8}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The point-slope form of an equation of a line:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have two points (7, -4) amd (-1, 3).
Calculate the slope:
[tex]m=\dfrac{3-(-4)}{-1-7}=\dfrac{7}{-8}=-\dfrac{7}{8}[/tex]
The point-slope form of an equation of a line:
[tex]y-(-4)=-\dfrac{7}{8}(x-7)\\\\y+4=-\dfrac{7}{8}(x-7)[/tex]
Convert to the slope-intercept form:
[tex]y+4=-\dfrac{7}{8}(x-7)[/tex] use the distributive property
[tex]y+4=-\dfrac{7}{8}x+\dfrac{49}{8}[/tex] subtract 4 = 32/8 from both sides
[tex]y=-\dfrac{7}{8}x+\dfrac{17}{8}[/tex]
The equation of the line passing through (7,-4) and (-1,3) has a slope of -7/8, the point-slope form is y + 4 = -7/8(x - 7), and the slope-intercept form is y = -7/8x + 17/8.
To write the equation of the line that passes through the points (7,-4) and (-1,3), we first need to calculate the slope of the line using the formula m = (y2 - y1) / (x2 - x1).
Applying this to our points, we get m = (3 - (-4)) / (-1 - 7), which simplifies to m = 7 / -8 = -7/8. Now, using the point-slope form y - y1 = m(x - x1), and the point (7, -4), we can write the equation as y - (-4) = -7/8(x - 7).
Next, to convert this to slope-intercept form, we simplify the point-slope equation to solve for y: y + 4 = -7/8x + 49/8, and then subtract 4 (or 32/8) from both sides to get y = -7/8x + 17/8. This is our slope-intercept form, where -7/8 is the slope, and 17/8 is the y-intercept.

Simplify 8x + 9x completely.
Answer:
[tex]17x[/tex]
Step-by-step explanation:
[tex]8x + 9x = 17x[/tex]
To simplify the expression 8x + 9x, you combine the like terms by adding the coefficients. The result is 17x.
Explanation:The process involved in simplifying an equation like this is known as combining like terms. In this example, the terms are 8x and 9x. Because they both contain the same variable, x, you can combine them.
To perform this operation, you add the coefficients (the numbers in front of the variable). In this case, the coefficients are 8 and 9. So, 8x + 9x simplifies to 17x.
Therefore, the simplified form of the equation 8x + 9x is 17x.
