6. Identify the recursive formula for the sequence 3, –15, 75, –375, . . .
Answer:
first option
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence, that is
r = - 15 ÷ 3 = 75 ÷ - 15 = - 375 ÷ 75 = - 5
The recursive formula allows a term in the sequence to be found by multiplying the previous term by r , thus
f(n) = - 5f(n - 1) if n > 1
with f(1) = 3 ← first term
Answer:
D . f(n)=f(1)=3
f(n)= -5f(n-1)if n >1

HELP ASAP !! Suppose line segment AB has one endpoint at A(0, 0). If (5, 3) is the midpoint of AB, what
are the coordinates of point B?
Answer:
(9,3)
Step-by-step explanation:
did the calculations
The co-ordinates of point B is ( 10, 6 ).
What is a line segment ?A line segment is a subset of a line which has two endpoints.
According to the given question a line segment AB has one endpoint at A(0, 0) which is (x₁,y₁)
Given midpoint is at (5,3).
Let B is (x₂,y₂).
We know midpoint of x is (x₁ + x₂)/2 and midpoint of y is (y₁ + y₂)/2.
∴ 5 = ( 0 + x₂ )/2
5 = x₂/2
x₂ = 10.
AND
3 = ( 0 + y₂ )/2
3 = y₂/2
y₂ = 6.
( x₂,y₂ ) = (10,6)

If UV = 13, VW = 3x − 5, and UW = 5x − 18, what is UW? Simplify your answer and write it as a proper fraction, mixed number, or integer.
I got stuck here. If you could (or not) type step by step.
Since UV and VW make up UW, we can set add together UV and VW and set them equal to UW.
5x - 18 = 13 + 3x - 5
Let's combine like terms on the right side.
5x - 18 = 3x + 8
Subtract 3x from both sides and add 18 to both sides.
2x = 26
Divide both sides by 2
x = 13
We know that UW = 5x - 18. Let's plug 13 in for x.
UW = 5(13) - 18 = 65 - 18 = 47.

Find the remaining side of a 45° – 45° – 90° triangle if the shorter sides are 2/3 each .
Answer:
The length of the longer side is 2√2/3
Step-by-step explanation:
A 45-45-90 triangle is a right-angled triangle.
In fact, since it has two angles equal, it is a right angled isosceles triangle. What we are saying is that two of its sides are equal.
Hence, we have two short sides which are the opposite and the adjacent and a longer side which is the hypotenuse
Thus, to find the length of the longer side, we employ Pythagoras’ theorem and it states that the square of the hypotenuse equals the sum of the squares of the two other sides;
Mathematically, let’s call the longer side x
so x^2 = (2/3)^2 + (2/3)^2
x^2 = 4/9 + 4/9
x^2 = 8/9
x = √(8/9)
x = 2√2/3
Kathy read 296 pages of her 590−page novel in 10 days. How many pages per day must she now read in order to complete the book and return it within the library's 17−day deadline?
Answer:
The answer is 42 pages per day.
Step-by-step explanation:
The answer is 42 because 590 minus 296 equals 294 and since the deadline is 17 days and he has done 10 already then 294 divided by 7 equals 42.
13/15 × 1 1/39 multiplying/dividing fractions help me
Before multiplying two fractions together, always try to cross-cancel.
So in this problem, the 13 and 39 cross-cancel to 1 and 3.
So we have 1/15 × 11/3 which is 11/45.

Please help ive lost my ability for simple patterns. Its due by end of day. Pt. 3
Step-by-step explanation:
On the right side, 3 + 4 + 7 = 14, so the other two numbers must add up to 22. Therefore, they must be 10 and 12.
Let's assume 12 is the top number and 10 is the bottom number.
The left side adds up to 12 + 9 + 2 = 23, so the other two numbers add up to 13. Therefore, they must be 5 and 8.
The bottom side adds up to 10 + 1 + 11 = 22, so the other two numbers add up to 14. Therefore, they must be 6 and 8.
So the bottom left number is 8.
Drag the tiles to the correct boxes to complete the pairs. Match the angle measurements in radians with equivalent measurements less than or equal to 360°.
Answer:
60° =19π/3
288°=22π/9
315°=23π/4
80°=18π/5
Step-by-step explanation:
The question is incomplete. Find the completed question in the attachment.
We are to convert the radian values to the corresponding degrees that are less than 360°
Since π rad = 180°
For 23π/4:
If π rad = 180°
23π/4 = x
Cross multiply:
πx = 23π/4 × 180
x = 23π/4π × 180
x = (23×180)/4
x = 1035°
Next is to scale down 1035° to a degree less than 360 and to do this we will be subtracting multiples of 360° from the value gotten.
x = 1035 - (360×2)
x = 1035 - 720
x = 315°
Hence 23π/4 = 315°
For 18π/5:
If π rad = 180°
18π/5 = y
Cross multiply:
πy = 18π/5 × 180
y = 18π/5π × 180
y = (18×180)/5
y = 648°
In scaling down:
y = 648°-360°
y = 288°
Hence 18π/5 = 288°
For 22π/9:
If π rad = 180°
22π/9 = t
Cross multiply:
πt = 22π/9 × 180
t = 22π/9π × 180
t = (22×180)/9
t = 440°
In scaling down:
t = 440-360°
t = 80°
Hence 22π/9 = 80°
For 19π/3:
If π rad = 180°
19π/3 = y
Cross multiply:
πy = 19π/3 × 180
y = 19π/3π × 180
y = (19×180)/3
y = 3420/3
y = 1140°
In scaling down:
y = 1140°-(3×360)°
y = 1140-1080
y = 60°
Hence 19π/3 = 60°
Answer:
the other person was almost right except they mixed up 2 of them. this is the right answer, i hope this helps :)
60° =19π/3
288°=18π/5
315°=23π/4
80°=22π/9

To find the area of the larger figure, let's multiply the length by the width.
9 ft * 4 ft = 36ft^2
Let's do the same thing with the smaller figure.
3 ft * 4 ft = 12ft^2
Let's add the area of both figures together.
36ft^2 + 12ft^2 = 48ft^2
