The recursive formula for this sequence is = -7;
=
+ 10
Step-by-step explanation:
The recursive formula of the arithmetic sequence is:
= first term;
=
+ d
is the first term in the sequence
is the nth term in the sequence
the term before the nth term
- n is the term number
- d is the common difference
∵ The sequence is -7 , 3 , 13 , 23 , 33 , 43 , ........
∵ 3 - (-7) = 3 + 7 = 10
∵ 13 - 3 = 10
∵ 23 - 13 = 10
- There is a constant difference 10 between the consecutive terms
∴ The sequence is an arithmetic sequence
∵ The first term is -7
∴ = 7
∵ The common difference is 10
∴ d = 10
- Substitute in the formula above by -7 and d by 10
∴ = -7;
=
+ 10
To check the formula find the second term
∵ n = 2
∴ = -7;
=
+ 10
∴ =
+ 10
∵ = -7
∴ = -7 + 10 = 3 which is right
The recursive formula for this sequence is = -7;
=
+ 10

Answer:
1) It has only two dimensions . FALSE
2). Its cross section is in the shape of a circle . TRUE
3) Its surface area is measured in cubic units. FALSE
4) It has a radius that is always a perfect square. FALSE.
Step-by-step explanation:
Sphere: Sphere is a 3 dimensional perfectly round object.
Here, all point lying at the circumference are at equal distance from the center.
The given statements are:
1) It has only two dimensions .
FALSE, a 2 D figure is a circle not a sphere. Sphere is 3 D.
2). Its cross section is in the shape of a circle .
TRUE, any cross section of a sphere is always a circle.
3) Its surface area is measured in cubic units.
FALSE, Surface area of a sphere = sq. units
4) It has a radius that is always a perfect square.
FALSE. A sphere can be of any possible radius.
Answer:
The unit rate is equal to
Step-by-step explanation:
we know that
The unit rate is the ratio of two measurements in which the second term is equal to one
In this problem to find the unit rate, divide the total cost of cereal by the total weight of cereal
so
therefore
The unit rate is equal to
