Shereena made the following table she can’t decide if it’s arithmetic or geometric sequence look at the picture bellow and answer the two questions pleaseeeeee
Answer:
Step-by-step explanation:
The characteristic of geometric sequences is that any term divided by the previous term is a constant, called the common ratio. Each term in this sequence is 2 times the previous term. In this case the sequence is an=2(2)^x.
If it were an arithmetic sequence any term subtracted by the previous term would be constant, called the common difference.
Which list of numbers is in order from greatest to least?
Answer:
J
Step-by-step explanation:
it is 6, 2 1/3(7/3), 2, 1/4, 0, -5
Answer:
J.
Step-by-step explanation:
Greatest to Least :
6 numbers, 3 different types.
We have negatives, positives, and fractions in this list.
So what would we need to do first is decrypt the fractions, so how many times does 7 go into 3? 2 times, and it would 1/3 left, making the improper fraction into 2 1/3
So we have the greatest, 6
Then with the next 2 1/3 (7/3)
Then with 2
Then with 1/4
Then with 0
And since negative number are below 0
-5 would be the least number

g Suppose that a large mixing tank initially holds 500 gallons of water in which 50 pounds of salt have been dissolved. Another brine solution is pumped into the tank at a rate of 3 gal/min, and when the solution is well stirred, it is then pumped out at a slower rate of 2 gal/min. If the concentration of the solution entering is 2 lb/gal, determine a differential equation (in lb/min) for the amount of salt A(t) (in lb) in the tank at time t > 0. (Use A for A(t).)
Answer:
the required differential equation is dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb
Step-by-step explanation:
Given the data in the question;
A(t) is the mass of the salt in in the tank at time t
the new volume of the solution in the tank increases by one gallon each minute
so
dA/dt = ( Rate in) - ( Rate out)
dA/dt = ( 3 gal/min × 2 lb/gal ) - ( 2 gal/min × [tex]\frac{A}{t+500}[/tex] lb/gal )
dA/dt = 6 - [tex]\frac{2A}{t+500}[/tex]
dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb
Therefore, the required differential equation is dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb

Please help quickly thanks
Answer:
Step-by-step explanation:
6=42/j multiply both sides by j
6j=42 divide both sides by 6
j=7
Answer:
J=7
Step-by-step explanation:
6=42/j multiply both sides by j
6j=42 divide both sides by 6

What is the area of a triangle with a base of 7 units and a height of 11 units?
A. 154 sq. units
B. 38.5 sq. units
C. 19.25 sq. units
D. 77 sq. units
Answer:
B
Step-by-step explanation:
Area of a triangle formula: 1/2bh
1/2*7*11 = 38.5 sq units
The value of area of a triangle with a base of 7 units and a height of 11 units is,
⇒ Area of triangle = 38.5 units²
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Base of triangle = 7 units
Height of triangle = 11 units
We know that'
Area of triangle = 1/2 x Base x Height
Hence, We get;
The value of area of a triangle with a base of 7 units and a height of 11 units is,
⇒ Area of triangle = 1/2 x Base x Height
⇒ Area of triangle = 1/2 x 7 x 11
⇒ Area of triangle = 38.5 units²
Thus, The value of area of a triangle with a base of 7 units and a height of 11 units is,
⇒ Area of triangle = 38.5 units²

If triangle ACD is similar to triangle ABE, find the value of x?
The value of x and y from the given figure is 2.1 units and 4.5 units.
Given that, triangle ACD is similar to triangle ABE.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Here, AB=3, AC=5, BE=x, AE=y, ED=3 and CD=3.5
AD=AE+ED
AD=y+3
Now, AB/AC = AE/AD = BE/CD
So, 3/5 = y/(y+3) = x/3.5
⇒ 3/5 = x/3.5
⇒ 3×3.5=5x
⇒ 5x=10.5
⇒ x=10.5
⇒ x=2.1
3/5 = y/(y+3)
⇒3y+9 =5y
⇒2y =9
⇒y =4.5
Therefore, the value of x and y from the given figure is 2.1 units and 4.5 units.

A rectangular room is 14 feet by 20 feet. A rectangular rug is placed in the room so that a 2-foot border of floor around the edge of the room is not covered by the rug. What is the area of the rug?
Answer:
the rug should be 10 feet by 16 feet
this makes the area 160 foot squared
Step-by-step explanation:
there is a 2 foot border on each side so the total area loses 4 feet from length. this gives 10 feet by 16 feet.
