The fifth term of a non-linear sequence is 9.
The term-to-term rule is divide by 3'.
Work out the second term of the sequence.
Answer:
a₂ = 243
Step-by-step explanation:
The term to term rule from left to right in the sequence is divide by 3
The term to term rule from right to left is the opposite, multiply by 3
Given
a₅ = 9, then
a₄ = 9 × 3 = 27
a₃ = 27 × 3 = 81
a₂ = 81 × 3 = 243 ← required term
A statement that two ratios are equal is called a
The answer is proportion. A proportion basically equates two ratios.
A statement that two ratios are equal is called a proportion.
In a proportion, the four quantities involved are related in such a way that the first ratio is equal to the second ratio. It can be represented in the form of "a:b = c:d," where "a" and "b" are the terms of the first ratio, and "c" and "d" are the terms of the second ratio.
Proportions are used in various mathematical applications, such as solving problems involving ratios, scaling, similarity, and solving for unknown values. They provide a way to compare quantities and establish relationships between them based on their relative sizes.

6 lumberjacks can cut down 15 mahogany trees in 2 hours. How much longer will
it take 8 lumberjacks to cut down 35 mahogany trees working at the same rate?
B. 1}hr
c.hr
A. 3hr
D. 21hr
9514 1404 393
Answer:
3.5 hr
Step-by-step explanation:
We assume that "the same rate" means effort per tree is a constant. "Effort" is measured as the product of lumberjacks and hours. Then ...
(lumberjacks)(hours)/trees = (6)(2)/15 = (8)(t)/35
Multiplying by 35/8, we have ...
(35/8)(12/15) = t = (3·4·5·7)/(2·3·4·5) = 7/2 = 3.5
It will take 8 lumberjacks 3.5 hours to cut down 35 trees.
What is the equation in point-slope form of the line that passes through (-9, 12) with a slope of 5/6?
A. y-12=6/5(x+9)
B. y-12=5/6(x+9)
C. y-9=5/6(x-12)
D. y-12=6/5(x-9)
Answer:
The equation of the line is y - 12 = [tex]\frac{5}{6}[/tex] (x + 9) ⇒ B
Step-by-step explanation:
The slope-point form of the linear equation is
y - y1 = m(x - x1), where
m is the slope of the line(x1, y1) are the coordinates of a point lie on the line∵ The slope of a line is [tex]\frac{5}{6}[/tex]
∴ m = [tex]\frac{5}{6}[/tex]
∵ The line passes through point (-9, 12)
∴ x1 = -9 and y1 = 12
→ Substitute these values in the form of the equation above
∵ y - 12 = [tex]\frac{5}{6}[/tex] (x - -9)
→ Remember (-)(-) = (+)
∴ y - 12 = [tex]\frac{5}{6}[/tex] (x + 9)
∴ The equation of the line is y - 12 = [tex]\frac{5}{6}[/tex] (x + 9)

If the leading coefficient is negative, always factor out the negative.
-x^2+5x-6
Answer:
-1(x-2)(x-3)
Step-by-step explanation:
first we factor the negative:
-1 (x^2 - 5x +6 )
the next step, (if possible) is to guess 2 numbers that multiplied are 6
and added are -5
in this case is easy to see that those numbers are -2 and -3
The solution then is:
-1(x-2)(x-3)
If guessing the 2 numbers doesn't work, you need to complete the square

What is the value of x in the following equation? 5(x + 3) = 30x
Answer:
x= 3/5
Step-by-step explanation:
5(x+3)=30x
5x+15=30x
-5x -5x
15=25x
x= 3/5
Answer:
3/5
Step-by-step explanation:
5(x+3)= 30x [
or,
(5×x)+(5×3)= 30x
or,
5x+15= 30x
or,
5x+15-5x= 30x-5x [The result or root of the equation remains same . if we multiply, divide, add or subtract any . number from each side of the equation]
or,
15= 25x
or,
15/25= x
or,
3/5= x
So, the value of x is 3/5

Find FG. (idk how to write the question but apparently it needs to be longer)
Answer:
FG = 18
Step-by-step explanation:
FG + GH = FH
FG + 31 = 49
Subtract 31 from each side
FG +31-31 = 49-31
FG = 18
Answer: FG is 18
Step-by-step explanation: FG + GH is FH, GH is 31 and then you substitute 31 in for GH which makes the equation FG+31=49 49-31 is 18 which means FG is 18
What is the range of the function graphed below?
Answer:
Range: [tex]y\in[-4,0)\cup[2,+\infty)[/tex]
Step-by-step explanation:
Range of a Function
Given a real function f(x), the Range of f is the set of all the values the function can take when x varies within the domain of f.
If we have the graph of the function, a practical rule can be used to find the Range. Imagine a horizontal rule moving from minus infinity to plus infinity. If that rule touches the graph of the function, the vertical height or y-value belongs to the range.
Consider the function provided in the image. If our horizontal rule comes from minus infinity, it won't touch the graph until it reaches the value y=-4. Note the endpoint has a filled dot, meaning the point belongs to the function. The range starts from -4.
Going up in values of y, we touch the function until y=0. But that endpoint is marked with an empty dot, so that point does not belong to the function.
The first interval of the range is [-4,0)
Moving up the rule, we touch the function again when y=2 (included) and we note the function continues to go up to plus infinity (signaled with the arrow). Thus, the second interval is [2,+∞).
The range of f is the union of both intervals:
Range: [tex]y\in[-4,0)\cup[2,+\infty)[/tex]

If m<5=63°, find the measure of <3.
Answer:
angle 3's measurement should be 117 degrees
hope this helps :)
The measure of angle 3 is 117 degrees.
Calculation of an angle:In terms of geometry, an angle refers to the figure i.e. credited by two rays that should be met out at a common endpoint. An angle should be presented by the symbol ∠.
Since the angle 5 is 63 degrees
and, the total of two angles is 180 degrees
So, the angle 3 is
= 180 - 63
= 117 degrees
hence, The measure of angle 3 is 117 degrees.
