5.) Write both an explicit equation and a recursive equation for the sequence 4, 2, 1,05,0.25...

Explicit equation:


Recursive equation:


HURRY PLEASE!!!​

Answers

Answer 1

Since the common ratio is 0.5, hence the recursive equation will be an = 0.5an-1 and Tn = 4(0.5)^n-1 (Explicit equation)

Sequence and series

Sequences are number arranged in a specified pattern. Given the geometric sequence

4, 2, 1,05,0.25...

Common ratio. = 2/4 = 0/.5

First term a = 4

The nth term of the  sequence in explicit form is Tn = ar^n-1

Tn = 4(0.5)^n-1 (Explicit equation)

For the recursive function

Explicit equation = an =ran-1

Since the common ratio is 0.5, hence the recursive equation will be an = 0.5an-1

Alicia will construct a rectangle that has a height of 4 units and an area of up to 48 square units. Which inequality represents all the possible lengths in units of the bases, b, that Alicia can use to construct this rectangle?

Answers

Answer:

b ≤ 12

Step-by-step explanation:

The area of the rectangle is given by length multiplied by breadth.

The area of the rectangle up to 48 units square means that it can be 48 or less than 48.

If the height given is taken as the width of the rectangle then we can find the base which will be the length of the rectangle.

Area = length * breadth

4units * base ≤ 48 units square

base ≤ 48 units square/4 units

base ≤ 12 units

b ≤ 12 units

At middle school lunch in the cafeteria, 60% of the students pack a lunch and 40% buy a lunch. Of the students who pack a lunch, 70% have a cookie. What is the percent of the students who have a cookie at lunch?

Answers

Answer:

42%

Step-by-step explanation:

The computation of the percentage is shown below:

Here we assume that there are 100 students

So according to the question

60% of the students would pack the lunch i.e. 60 students

And, 40% of the students buy a lunch i.e. 40 students

Now the students who pack the lunch they have 70% of cookie

So, 70% of 60 students = 42 students

Now the percentage is

= 42 students ÷ 100 students

= 42%

The area of a square floor on a scale drawing is 49 square centimeters, and the scale drawing is 1 centimeter:3 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?

Answers

Answer:

the area of the actual floor is  784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant

Step-by-step explanation:

The computation of the area and the ratio of the area is shown below:

The ratio of the drawing area to the actual area is  

= ((1 cm) ÷ (4 ft))²

= (1 cm²) ÷ (16 ft²)

 Now the actual floor area is  

(16 ft²) ÷ (1 cm²) = actual area ÷ (49 cm²)

= (16 ft²) × 49 ÷ 1

= 784 ft²

hence, the area of the actual floor is  784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant

In the diagram ABC is congruent to DEF. aging the values of x and y

Answers

Answer:

x = 1, y = 46

Step-by-step explanation:

Since the triangles are congruent then corresponding sides and angles are congruent, then

DE = AB , that is

3x + 6 = 9 ( subtract 6 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

and

∠ C = ∠ F

10x + y = 56 ( substitute x = 1 )

10(1) + y = 56

10 + y = 56 ( subtract 10 from both sides )

y = 46
