Which of the following functions best defines this sequence?
A.) f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1
B.) f(1) = 9, f(n + 1) = f(n) + 4; for n ≥ 1
C.) f(1) = 9, f(n + 1) = f(n) − 5; for n ≥ 1
D.) f(1) = 9, f(n + 1) = f(n) + 5; for n ≥ 1
Answers
Answer:
A.) f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1
Step-by-step explanation:
The first four terms of a sequence are shown below.
Let
f(1) = 9
f(2) = 5
f(3) = 1
f(4) = -3
Therefore we know that
f(2) - f(1) = 5 - 9
f(2) - f(1) = - 4
f(2) = f(1) - 4
f(3) - f(2) = 1 - 5
f(3) - f(2) = - 4
f(3) = f(2) - 4
f(4) - f(3) = -3 - 1
f(4) - f(3) = - 4
f(4) = f(3) - 4
Hence the answer is A.) f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1
The cost of 3 DVD's and 4 CD's is £62.00. The cost of 4 DVD's and 3 CD's is £64.00. Find the cost of each.
Help!!!
Answers
Answer:
the cost of each is £10 and £8 respectively
Step-by-step explanation:
Let us assume the cost of per DVD be x
And the cost of per CD be y
Now as per the question
The following equations should be made
3x + 4y = £62.00
4x + 3y = £64.00
Now multiply by 4 in equation 1 and 3 in equation 2
12x + 16y = £248
12x + 9y = £192
7y = £56
y = £8
Now put the value of y in any of the above equation
3x + 4( £8) = £62
3x + £32 = £62
3x = 30
x = £10
Hence, the cost of each is £10 and £8 respectively

Long will it take to bravel
720 km at sume
average Speed?
Answers
Answer:
12 hours.
Step-by-step explanation:
A motorist takes 5 hours to travel 300km
This means that his velocity, in km per hour, is given by:
v = 300/5 = 60 km/h
How long will it take to travel 720 km at same average speed?
720 km, 60 an hour. So
720/60 = 12
It will take 12 hours.

(h,k)=center
r^2=radius
in this case (h,k)=(-2,3)
r^2=r^2
10^2=100

557.8m²Step-by-step explanation:
2 opposite semicircle are same
diameter = 9m
radius = 4.5m --- (diameter = 1/2radius)
area of semicircle = 1/2 × π × radius²
= 1/2 × 3.14 × 4.5×4.5
= 31.79m²
2 semicircles area = 31.79 × 2
= 63.8m²
______________________________

other 2 opposite semicircle are same
diameter = 20m
radius = 10m --- (diameter = 1/2radius)

= 157m²
2 semicircles area = 157 × 2
= 314m²

Stacia walked a total of 30,375 feet. If 2 miles is 10,560 feet, how far did Stacia walk in miles?
Answers
Answer:
62
Step-by-step explanation:
Answer:
I believe the answer is 5.8 miles
Step-by-step explanation:
I believe this is the correct answer, although it is possible I am wrong.
This is how I solved this problem:
I divided 10,560 feet by 2, which equals 5280 feet in a mile
Then I divided 30,375 feet by 5280 feet to get 5.7528409
Since there is no way this is the correct simplification, you need to round to the nearest tenth.
5.7528409 is about 5.8 miles

Type your answer as a mixed number
4 times as much as the sum of 1/5 and 2/3
Answers
Answer: 3 7/15
Step-by-step explanation: You first do 1 /5 plus 2/3.But they don't have the same denominator so you make it the same which you can make it to 15 so you make both denominator of 1/5 and 2/3. So 1 /5 change to 3/15 and 2/3 change to 10/15.Now add 3/15 to 10/15 which is 13/5.After that you do 4 times 13/5.But change 4 to a fraction to make it easy which is 4/1.Now multiply 4/1 by 13/5 which gives you 52/15 .Finally change 52/15 to a mixed number which is 3 7/15.

How many cubes of edge 4cm, each can be cut out from cuboid whose length, breadth and height are 20 cm, 18 cm and 16 cm respectively.
Answers
Answer:
90 cubes.
Step-by-step explanation:
First we find volume of the cuboid.
Volume = l x b x h = 20 x 18 x 16 = 5760 cm³
Now,
Volume of a single cube = l³ = 4³ = 64
No of cubes that can be cut out from the cuboid is
= Volume of cuboid/ volume of cube
= 5760/ 64
= 90 cubes
