Answer:

Alexander estimate is not a good estimate

Step-by-step explanation:

Breakfast = $2

Lunch = $8

Dinner = $8

Total amount spent on food each month = (cost of breakfast × number of days) + (cost of lunch × number of days) + (cost of dinner × number of days)

= ($2 × 30) + ($8 × 30) + ($8 × 30)

= $(60 + 240 + 240)

= $540

Total cost estimate of food in a month = $540

Alexander estimate is not a good estimate

Question 3 (1 point)
Virty [35]

Answer:

The answer to your question is (4, 6)

Step-by-step explanation:

Data

E ( 9 , 7 )

F ( - 1, 5)

Formula

Xm = \frac{x1 + x2}{2}

Ym = \frac{y1 + y2}{2}

Substitution and simplification

Xm = \frac{9 -1}{2}

Xm = \frac{8}{2}

      Xm = 4

Ym = \frac{7 + 5}{2}

Ym = \frac{12}{2}

      Ym = 6

Result

            (4 , 6)

Find the recursive rule, explicit rule, and f(20)
DiKsa [7]

Answer:

Recursive:

f(1)=35, f(n)=f(n-1)+10

Explicit:

f(n)=35+10(n-1)

And the 20th term is 225.

Step-by-step explanation:

We have the sequence:

35, 45, 55, 65.

Notice that each subsequent term is 10 more than the previous term.

Therefore, our common difference is (+)10.

Recursive Rule:

The standard format for the recursive rule is:

f(n)=a, f(n)=f(n-1)+d

Where a is the initial term and d is the common difference.

From our sequence, we know that a the initial term is 35.

And as determined, our common difference d is 10.

Substitute. Hence, our recursive rule is:

f(1)=35, f(n)=f(n-1)+10

Explicit Rule:

The standard format for the explicit rule is:

f(n)=a+d(n-1)

Where a is the initial term and d is the common difference. So, let’s substitute 35 for a and 10 for d. Hence, our explicit formula is:

f(n)=35+10(n-1)

Now, let’s find the 20th term. We will utilize the explicit rule since the recursive rule can get tedious. Substitute 20 for n because we would like to 20th term. Thus:

f(20)=35+10(20-1)

Evaluate:

\begin{aligned} f(20)&=35+10(19) \\ f(20)&=35+190 \\ f(20)&=225 \end{aligned}

Hence, the 20th term is 225.
