Both numbers (9.00 and 4.25) have three sig-figs. This means that the final answer will have three sig-figs as well.

Multiply the numbers to get: 9.00*4.25 = 38.25 which rounds to 38.3 because the answer must have three sig-figs. 

The units will be "square inches" or "inches^2" or "in^2". There are various ways to write the units portion.

Overall, the final answer is 38.3 square inches.

Which formula can be used to describe the sequence?
mafiozo [28]

Answer:

The formula  that can be used to describe the given  sequence is f(x)=-4(6)^{x-1}

Step-by-step explanation:

Given : sequence -4,  −24, −144,...

We have to find the formula that can be used to describe the given sequence  -4,  −24, −144,...

A geometric sequence is a sequence in which each higher term is multiplied by a constant number called common ratio.

Written as a, ar , ar², ar³., ....

and general term is calculated as a_n=ar^{n-1}

Where a is first term and r is common ratio.

Consider the given sequence  -4,  −24, −144,...

We find the common ratio ,

a=-4, \\\\ar=-24,\\\\\ ar^2=-144

Thus, common ratio is given as r=\frac{ar}{r}=\frac{-24}{-4}=6

Thus, the given sequence is a geometric sequence.

The general term is given by a_n=ar^{n-1}

Put a = -4 , r = 6

We have

a_n=-4(6)^{n-1}

Thus, the formula  that can be used to describe the given  sequence is f(x)=-4(6)^{x-1}

In a​ poll, 22​% of 714 surveyed adults said that . What is the actual number of adults who said that
Eva8 [605]

Answer:

<h2> 157 surveyed adult </h2>

Step-by-step explanation:

IF 22% of 714 surveyed adult made a statement, the actual number of those that made the statement can be gotten by simply evaluating 22% of 714 as shown below;

= 22% of 714

= 22/100 * 714

= (22*714)/100

= 15708/100

= 157.08

≈ 157 surveyed adult

<em>This means that about 157 surveyed adults made the statement. </em>

Write the algebraic expression for: the sum of a number and 5 decreased by twice the number.
Vera_Pavlovna [14]

The algebraic expression for: the sum of a number and 5 decreased by twice the number is (n + 5) - 2n

<h3>Algebra</h3>

let

  • The unknown number = n

sum of a number and 5

= n + 5

decreased by twice the number

= -2(n)

= - 2n

sum of a number and 5 decreased by twice the number

= (n + 5) - 2n

= n + 5 - 2n

= 5 - n

Therefore, the algebraic expression which can be used to represent; the sum of a number and 5 decreased by twice the number is (n + 5) - 2n
