Answer:
[tex]a_n=3(-3)^{n-1}[/tex]
Step-by-step explanation:
Geometric sequence
General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termr is the common ratioGiven:
[tex]a_1=3[/tex][tex]a_2=-9[/tex]To find the common ratio r, divide consecutive terms:
[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{-9}{3}=-3[/tex]
Therefore, the equation is:
[tex]a_n=3(-3)^{n-1}[/tex]

HELP QUICK!!!!
Answer:
C = 2πr
Step-by-step explanation:
The circumference of a circle is calculated by the formula here,
C is the circumference of the circle.
r is the radius of the circle.
π is 22/7 or 3.14.
In the given options π is not missing.
Therefore the formula that relates circumference and radius is C = 2πr.
Answer:

If B is 60% more than A, then A is
A. 37.5% less than B.
B. 37.5% of B
C. 60% less than B
D. 60% of B
Answer:
37.5% less than B
Step-by-step explanation:
It is given that B is 60% more than A.
A (160%) = BA = B / (160%)A = B / (8/5)A = 5B/8A = 0.625BA = (62.5%) BSince A is 62.5% of B, it is 37.5% less than B.
Answer:
A. 37.5% less than B
Step-by-step explanation:
We can write an equation to model this:
B being 60% more than A means that:
B=0.6A+1A
B=1.6A
Let's isolate A.
A=B/1.6
Multiply the top and bottom by 10 to get whole numbers
A=10B/16
Simplify
A=5B/8
5/8 = 62.5%
A=0.625B
Therefore, A is 62.5% of B
This means that A is 37.5% less than B.

Answer:120square unit
Step-by-step explanation:khan
What is the square root of A=121 ft2
The result of the square root of the equation A = 121 ft² is √A = 11 ft
What are square roots?Square roots are numbers multiplied by itself to give another number
How to determine the square root?The equation is given as:
A = 121 ft²
Take the square root of both sides
√A = √121 ft²
Evaluate the square root
√A = 11 ft
Hence, the square root of the equation A = 121 ft² is √A = 11 ft

Write an equation in slope-intercept form for the relationship in the table.
The equation of the relationship in the table, in slope-intercept form, is: y = x + 5.
What is the Slope-intercept Form?The slope-intercept form for a relationship between two variables x and y is represented as: y = mx + b, where:
m = slope = change in y / change in xb = y-intercept.Slope (m) = change in y / change in x = 47 - 42 / 42 - 37 = 5/5
Slope (m) = 1
Substitute (37, 42) = (a, b) and m = 1 into y - b = m(x - a):
y - 42 = 1(x - 37)
y - 42 = x - 37
y = x - 37 + 42
y = x + 5
Equation for the relationship in the table is: y = x + 5

The strip below is cut into 9 equal bars.
Shade 2/3 of this strip.
Answer:
Shade 6 bars.
Step-by-step explanation:
You are asked to shade 2/3 of the strip. It is given that the strip has 9 equal parts. Multiply the number and fraction together:
[tex]9 * \frac{2}{3} = \frac{9}{1} * \frac{2}{3} = \frac{9 * 2}{1 * 3} = \frac{18}{3} = 6[/tex]

Given that 5 cos (x+8.5)° - 1 = 0
0° ≤x≤ 90, calculate correct to the nearest degree, the value of x.
Answer:
x = 70
Step-by-step explanation:
To solve for x, use inverse operations to undo the operations performed on x.

5cos(x +8.5)° -1 = 0 . . . . given
5cos(x +8.5)° = 1 . . . . . . add 1
cos(x +8.5)° = 1/5 . . . . . divide by 5
x° +8.5° = arccos(1/5) . . . . take the inverse cosine
x° = arccos(1/5) -8.5° ≈ 70° . . . . evaluate the expression
