The total surface area of the cylinder would be 748 sq inches. I have attached a picture of the work in case you need it. I hope this helps. :)

The answer is 15.4
22 over 7 is 3.14(pie) and you take 7(squared) and multiply that by 10 to get 15.4

Simplify the expression:<br> (3n)(2)

Arlecino [84]

Answer:

Step-by-step explanation:

3n+2)! / (3n-3)! = (3n+2)*(3n+1)*(3n)*(3n-1)*(3n-2)*(3n-3)! divided by (3n-3)! which becomes:

23! / 18! = (23 * 22 * 21 * 20 * 19 * 18! divided by 18! which becomes:

(23 * 22 * 21 * 20 * 19)

the result is 4037880

i used my ti-84 to take 23! and divide it by 18! and i got 4037880.

this confirms the solution is correct.

Answer:

a = - $\frac{9}{2}$ , b = - $\frac{25}{4}$

Step-by-step explanation:

To obtain the required form use the method of completing the square

add/ subtract ( half the coefficient of the x- term)² to x² - 9x

y = x² + 2(- $\frac{9}{2}$ )x + $\frac{81}{4}$ - $\frac{81}{4}$ + 14

= (x - $\frac{9}{2}$ )² - $\frac{81}{4}$ + $\frac{56}{4}$

= (x - $\frac{9}{2}$ )²- $\frac{25}{4}$ ← in the form (x + a)² + b

with a = - $\frac{9}{2}$ and b = - $\frac{25}{4}$

Using the equation y = 2x + 5 , what would the input need to be for an output of -45?

Semenov [28]

Answer:

-25

Step-by-step explanation:

Essentially, y is your output and x is your input.

Here's your base equation: y = 2x + 5

Knowing the information above, let's plug it in:

-45 = 2x + 5

(Subtract 5 from both sides)

-50 = 2x

(Divide both sides by 2 to isolate x)

-25 = x

And there you go.

The surface area of the three-dimensional figure is square centimeters?

Zina [86]

Answer:

Step-by-step explanation:

Alright, lets get started.

The surface area of the figure given is : The area of all shapes together

The figure has 2 similar triangles and 3 similar rectangles.

The area of 1 triangle =

$\frac{1}{2}*base*height$

The area of 1 triangle = $\frac{1}{2}*10*8.66=43.3$

So, the area of both triangles = $43.3*2=86.6$

The area of 1 rectangle = $width *length$

The of 1 rectangle = $10*15=150$

So, the area of all 3 rectangles = $3*150=450$

So, total area of figure = $86.6+450=536.6$

hence the surface area is 536.6 square centimeters : Answer

Hope it will help :)
