Answer:

Step-by-step explanation:

1: Base Surface Area = π×72

= 153.9380400259 millimeters2

Lateral Surface Area = π×7×√72 + 142

= 344.215921821 millimeters2

Total Surface Area = 498.1539618469 millimeters2

Rounded = 500 millimeters2

2:Base Surface Area = π×52

= 78.539816339745 centimeters2

Lateral Surface Area = π×5×√52 + 102

= 175.62036827602 centimeters2

Total Surface Area = 254.16018461576 centimeters2

Rounded 300 centimeters2

Find lim f(x), x->3- Can you please explain this. I dont know why but this is confusing me.

Hello,

$$ \lim_{x \to 3-} f(x)=1\ \ is\ since ( x\ \in\ Dom(f)\ and\ \forall\ \delta\ \textgreater\ 0 \ and\ $
$
$( x \in \ Dom( f ) \ and \ 3-\delta \ \le \ x \ \ \textless \ p ) == \textgreater \ 
1 - \epsilon \ \le\ f ( x )\ \le \ 1 + \epsilon \$

$$ \lim_{x \to 3+} f(x)=3$
$
$f(3)=7\\
\lim_{x \to 3} f(x) \ does\ not\ exist.$

Find the area of a circle whose circumference measures 28 centimeters.

vagabundo [1.1K]

Assume the radius is R.

2*pi*R = 28 -> R = 14/pi

So the area will be pi*R^2 = 196/pi

zhannawk [14.2K]

This A(n) = (24 members) + 5(members/week)(n-1) is correct, provided that we define the domain as [1, infinity). Thus, if n=1, A(1) = 24 + 5(0) = 24, which is correct.

1) Write the equation parallel to the following equations that would go through (2,7):

myrzilka [38]

Note: Your option 'b' is somewhat ambiguous, so I am assuming you meant to write the equation y=2x+3 for the 'b' option.

Answer:

the equation y = 2x + 3 has slope m=2 and the y-intercept is 3, and also PASSES through the point (2, 7).

Step-by-step explanation:

An equation parallel to the given line equation will have the same slope.

Given the point (2, 7) from which the equation passes through.

so checking all the equations in the options to check whether any equation passes through or not.

Checking the option 'a':

y = 3x - 2

Putting (2, 7)

7=3(2)-2

7=6-2

7=4

L.H.S is not equal to R.H.S

Therefore, the option 'a' is NOT correct.

So, the equation y = 3x - 2 will NOT PASS through the point (2, 7)

Checking the option 'b':

y = 2x + 3

Putting (2, 7)

7=2(2)+2

7=7

L.H.S is equal to R.H.S

Therefore, option 'b' is the CORRECT option.

So, the equation y = 2x + 3 will PASS through the point (2, 7)

Checking the option 'c':

y = x-6

Putting (2, 7)

7=2-6

7=-4

L.H.S is not equal to R.H.S

Therefore, the option 'c' is NOT correct.

So, the equation y = x-6 will NOT PASS through the point (2, 7)

Checking the option 'd':

y + 2x = 8

Putting (2, 7)

7+2(2)=8

7+4=8

11=8

L.H.S is not equal to R.H.S

Therefore, the option 'd' is NOT correct.

So, the equation y + 2x = 8 will NOT PASS through the point (2, 7)

Therefore, considering the above analysis, we conclude that:

Option 'b' is the CORRECT option.

So, the equation y = 2x + 3 will PASS through the point (2, 7).

also

The slope-intercept form of the equation is

$y=mx+b$

where m is the slope and b is the y-intercept.

Therefore, the equation y = 2x + 3 has slope m=2 and the y-intercept is 3, and also PASSES through the point (2, 7).
