Write an explicit equation for the sequence based on the graph at right.
Answer:
[tex]t(n)=12 \cdot 3^{n-1}[/tex]
Step-by-step explanation:
From inspection, the points on the graph are:
(1, 12)(2, 36)(3, 108)Therefore, as terms of a sequence:
[tex]t_1=12\\\\t_2=36\\\\t_3=108[/tex]
The difference between the y-coordinates is not equal, therefore the sequence is geometric.
Geometric sequence formula: [tex]t_n=t_1r^{n-1}[/tex]
As [tex]t_1=12 \implies t_n=12r^{n-1}[/tex]
To find r, divide one term by the previous term:
[tex]r=\dfrac{t_3}{t_2}=\dfrac{108}{36}=3[/tex]
Therefore, geometric sequence formula: [tex]t_n=12 \cdot 3^{n-1}[/tex]
Rationalise the denominator
Answer:
30+12(square root of 5)
Step-by-step explanation:
Answer:
30 + 12[tex]\sqrt{5}[/tex]
Step-by-step explanation:
To rationalise the denominator, multiply the numerator and denominator by the conjugate of the denominator.
The conjugate of 2[tex]\sqrt{5}[/tex] - 4 is 2[tex]\sqrt{5}[/tex] + 4 , then
[tex]\frac{12\sqrt{5}(2\sqrt{5}+4) }{(2\sqrt{5}-4)(2\sqrt{5}+4) }[/tex] ← expand denominator using FOIL
= [tex]\frac{120+48\sqrt{5} }{20-16}[/tex]
= [tex]\frac{120+48\sqrt{5} }{4}[/tex] ( divide each term on numerator by 4 )
= 30 + 12[tex]\sqrt{5}[/tex]
TBH, i am not sure what im doing. Here is a pic of the question.
Answer:
7
Step-by-step explanation:
The order of operations tells you to start any evaluation by looking at the innermost set of parentheses first.
Here, that means your first step is to find the value of h(-3). You do that by finding the input (x) value -3 in the table for h(x), and locating the corresponding output, h(x), which is 2.
Now, the problem becomes evaluating g(2).
You do the same thing for that function: locate the input x=2 in the table for g(x) and find the corresponding output: 7.
Now, you know ...
g(h(-3)) = g(2) = 7
Select ALL the true statements.
Answer:
A.
C.
Step-by-step explanation:
A. When adding a negative number to a positive, you subtract. 2.3 - 2.3 will equal 0.
B. When adding two negative numbers, you get an even smaller negative number. (-3.7) + (-4.1) = -7.8
C. When subtracting a negative number, the two negative signs become a positive. -12/4 is equal to 3. -2.6 + 3 is 0.4, which is positive.
D. 5/2 is the same as 2.5. If you subtract 2.5 from 2.5, you will get 0, which is not negative.
E. Two negative signs make a positive, so 72 + 100 is positive, not negative.

Answer:
x=6
Step-by-step explanation:
[tex]4(x+5)=9x+4x-34[/tex]
Step 1 :[tex]4x+20=9x+4x -34[/tex]
At step one, you have distributive property.
Step 2:[tex]4x+20=13x-34[/tex]
Step two you have to combine like terms.
Step 3:[tex]4x-4x+20=13x-4x-34[/tex]
Now is subtraction property
Step 4:[tex]20+34=9x-34+34[/tex]

Math question from my quizziz, I don't know if it's 1/a^9 or a^9
Answer:
red or 1/a9
Step-by-step explanation:
with that it is
a^ (3-12)
a^ (-9)
and then you can't have -9 in the top so you put it on the bottom
1/ a^9
Answer:
[tex]\frac{1}{a^9}[/tex]
Step-by-step explanation:
Cancel the common factor of [tex]a^3[/tex] and [tex]a^1^2[/tex]
[tex]a^3^-^1^2=a^-9[/tex]
Same things as 3-12 = -9
Hence, [Red] or [tex]\frac{1}{a^9}[/tex] is the correct Answer.

the area of a trapezoid is 42 square feet and its height is 4 feet. the length of one base of the trapezoid is 9 feet. what is the lenght of its other base
Answer:
12
Step-by-step explanation:
area of a trapezoid :
[tex]A = \frac{a+b}{2} h[/tex]
where a and b = length of bases and h = height
here, we are given the area, the length of one base and the height
we want to find the other base length
we can do this by plugging in what we are given and then solving for the unknown variable
first lets define our known variables
Area (A) = 42 , height (h) = 4 and length of one of the bases (a) = 9
we then plug this into the formula and solve for b, the other base length
recall formula : [tex]A = \frac{a+b}{2} h[/tex]
A = 42 , h = 4 , a = 9
[tex]42 = \frac{9+b}{2} 4[/tex]
now solve for b
divide both sides by 4
[tex]10.5=\frac{9+b}{2}[/tex]
multiply both sides by 2
21 = 9 + b
subtract 9 from both sides
12 = b
the other base length is 12
Rewrite the equation 3x – 5y=30 in slope-intercept form.
a. y= -3/5x +30
b. y= -5/3x -6
C. x= 5/3y -6
d. y = 3/5x - 6
Answer: D) y = 3/5x - 6
The correct answer is D. The equation in slope-intercept form is y = 3/5x - 6.

Answer:
Two points, (0,9) & (3,10)
Step-by-step explanation:
First point, look at the +9 which should signal that it is 0,9 because that is the y-intercept
Next, use rise/run system to use the slope (1/3) and find your next point
Go up 1 from 9 to 10 (this is the rise part)
Go horizontally 3 to get your x-axis point (this is the run part)

The function y = f (x) is linear. Given f-¹ (0) = 3 and f (1) = - 4, find the formula f (x) and f-¹ (x).
Answer:
f(3x) - 2g(x+1) = 12x - 5
Step-by-step explanation:
You've got f[g(x)] and g[f(x)] correct
However, f(3x) means substitute 3x for x in f(x):
f(3x) = 2(3x) - 3
⇒ f(3x) = 6x - 3
2g(x+1) = 2[4 - 3(x + 1)]
⇒ 2g(x+1) = 2[4 - 3x -3]
⇒ 2g(x+1) = 2[1 - 3x]
⇒ 2g(x+1) = 2 - 6x
f(3x) - 2g(x+1) = (6x - 3) - (2 - 6x)
⇒ f(3x) - 2g(x+1) = 12x - 5

How do you use bodams
Answer:
Step-by-step explanation:
The BODMAS rule states we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).
