Answer:

I can't see the line but if you start at a point where the line crosses over an intersecting corner and find the next nearest corner where it intersects the slope will be however many up(or down - if its down its negative) you have to go/ how many sideways you have to go

ex:

so in example A the slope would be 2/1 which simplifies to 2 and in example B the slope would be -3/2

Manuel incorrectly claimed that the surface area of the cylinder

Andre45 [30]

Answer:

25.9%

Step-by-step explanation:

Since, the actual dimensions of the cylinder is not given we can assume the some dimension to explain the problem

Let us assume the dimension of the cylinder be

radius= 3in

height= 5 in

The expression for the total surface area of a cylinder is

T. S. A. =2πrh+2πr^2

Let us plug in the values to to find TSA

T. S. A. =2×3.14×3×5+2×3.14×3^2

Solving we get

T. S. A. =94.26+56.556

T. S. A. =150.816 in^2

Now let us find the error

we know that error % is calculated as

%error= [actual value-expected value/expected value]×100

%error= [190 -150.816/150.816]×100

%error= [39.184/150.816]×100

%error= 0.259×100

%error= 25.9%

Consider the sequence: 3, 8, 13, 18, 23, ...The recursive formula for this sequence is:an = an-1 + 5In a COMPLETE sentence, expl

Leona [35]

Answer:

see the explanation

Step-by-step explanation:

we know that

In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant called the common difference

we have

$3, 8, 13, 18, 23,...$

Let

$a_1=3\\a_2=8\\a_3=13\\a_4=18\\a_5=23\\$

$a_2-a_1=8-3=5$ ------> $a_2=a_1+5$

$a_3-a_2=13-8=5$ ------> $a_3=a_2+5$

$a_4-a_3=18-13=5$ ------> $a_4=a_3+5$

$a_5-a_4=23-18=5$ ------> $a_5=a_4+5$

the common difference between consecutive terms is equal to 5

we can rewrite the formula as

$a_n=a_(_n_-_1_)+5$ -----> given formula

For n > 1

where

an is the term that you want to find (position n)

a(n-1) is the known term position (n-1)

Find a_8

For n=8

$a_8=a_(_8_-_1_)+5$

$a_8=a_7+5$

I need to know a_7

we know that

The general formula for arithmetic sequence is equal to

$a_n=a_1+d(n-1)$

where

an is the term that you want to find (position n)

a_1 is the first term

d is the common difference

n is the number of terms

we have

$a_1=3$

$d=5$

substitute

$a_n=3+5(n-1)$

$a_n=3+5n-5$

$a_n=5n-2$

For n=8

$a_8=5(8)-2$

$a_8=38$

2 3/8 - 4 1/2 + 3 1/8 - (1/2)

UkoKoshka [18]

let's convert the mixed fractions to improper fractions firstly.

$\bf \stackrel{mixed}{2\frac{3}{8}}\implies \cfrac{2\cdot 8+3}{8}\implies \stackrel{improper}{\cfrac{19}{8}}~\hfill \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}} \\\\\\ \stackrel{mixed}{3\frac{1}{8}}\implies \cfrac{3\cdot 8+1}{8}\implies \stackrel{improper}{\cfrac{25}{8}} \\\\[-0.35em] ~\dotfill$

$\bf \cfrac{19}{8}-\cfrac{9}{2}+\cfrac{25}{8}-\cfrac{1}{2}\implies \stackrel{\textit{using an LCD of 8}}{\cfrac{(1)19-(4)9+(1)25-(4)1}{8}}\implies \cfrac{19-36+25-4}{8} \\\\\\ \cfrac{4}{8}\implies \cfrac{1}{2}$
