Cylinder is consists of two circles at both sides .

There are two circles

Total area:-

The shape that makes up the top and bottom of a cylinder is Circle.

Where,

Since, There are two circles we will multiply the area by 2

Checking for a perfect cube

3.1    21x3-6x2+7x-2  is not a perfect cube

Trying to factor by pulling out :

3.2      Factoring:  21x3-6x2+7x-2

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  7x-2

Group 2:  21x3-6x2

Pull out from each group separately :

Group 1:   (7x-2) • (1)

Group 2:   (7x-2) • (3x2)

              -------------------

Add up the two groups :

              (7x-2)  •  (3x2+1)

Answer:

Step-by-step explanation:

When x=2, f(x)=4. This means that f(2)=4.

Answer:

undefined

Step-by-step explanation:

This line is a vertical line, meaning it goes up and down. Vertical lines do not have a slope, thus, the answer is undefined.

Answer:

Step-by-step explanation:

132 + (4x - 10) + (5x - 11) + 128 + (4x+2) = 540 All convex 5 sided figures have  540 degrees.        Remove the brackets.

132+ 4x - 10 + 5x - 11 + 128 +4x + 2 = 540      Collect like terms

13x + 241 = 540                                               Subtract 241 from both sides.

13x = 540 - 241

13x = 299                                                         Divide by 13

x = 299/13

x = 23

<P = 4x + 2

<P = 92 + 2

<P = 94

Answer:

D.  4.5 sec

Step-by-step explanation:

Once the rock is on the ground it has no height (h=0)    

h = -16t² + 320

0 = -16t² + 320

16t² = 320

t² = 20

t² = 20

t = √20

t= √4x5

t = 2√5

around 4.5 seconds

Answer:

1044 cm²

Step-by-step explanation:

dividend this polygon to 2 rectangular a horizontal and a vertical. then find area of this two rectangular and add together.

area of whole polygon= 30 × (46-21) + 14 × 21 =

30 × 25 + 294 = 750 + 294 = 1044 cm²

Answer:

Maria 69       Rizal    23

Step-by-step explanation:

M =Maria

(1/3)M = Rizal

                  M-46= (1/3)M

Multiply  both sides by 3 to eliminate fraction

3M-138 =M

138=2M

69= M   (Maria =69)

 69/3= 23

69-46=23

Answer:

$12,000

Step-by-step explanation:

Use the simple interest formula: P = A(1 + rt)

P = final balance (?)

A = starting balance (10,000)

r = interest rate (0.05)

t = years (4)

P = 10,000(1 + 0.05 · 4)

P = 10,000(1 + 0.2)

P = 10,000(1.2)

P = 12,000

Answer

6 with a remainder of 9

Step-by-step explanation:

Answer:

6.35

Step-by-step explanation:

"How many times does 26 go into 165?" is the same as asking "How much is 165 divided by 26?" Thus, the answer can be calculated as follows:

165/26 = 6.35

Tip: When you get a question like "How many times does 26 go into 165?", just think of it as how many times you can fit 26 into 165.

Answer:

rectangle, square, and trapezoid

Step-by-step explanation:

The equation is in the form of the linear line: y = mx +b where m is the slope.

Thus the slope is 1/6

Answer:

-12 and 2; it is factored as [tex](x+2)(x-12)[/tex]

Step-by-step explanation:

Since their product is negative, one is positive and the other is negative.

Moreover, since the sum is negative the greater of the two is negative.

Considering that factors of 24 are 1, 2,4,6, 12, 24 you have the following options:

-24 and 1. Sum gets to -23. Nope.

-12 and 2. Sum is indeed -10. Check!

-6 and 4. Sum is -2. Nope again.

The two numbers are thus -12 and 2. The factorization becomes

[tex]x^2-10x-24 = (x+2)(x-12)[/tex]

Answer

= 4 pizzas per dollar

Step-by-st:ep explanation:

This is a fraction equal to

32 pizza ÷ 8 dollars

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 8

32 pizza ÷ 8

8 dollars ÷ 8

=

4 pizza

1 dollar

=

4 pizza

dollar

= 4 pizzas per dollar
