Mathematics
1 answer:
Yuliya22 [10]3 years ago
8 0

Answer:

total surface area of cone is πr (r+l)

22/7 x 3 (3+4)

22/7*3 (7)

22 x 3 ( as 7 that was divided by 22 was cut out with 7 in the bracket)

hence,

TSA of cone = 66pi

Find the product. (-5a2)3 · a5
lesya692 [45]

Answer:

-125a^{11}

Step-by-step explanation:

The expression that we have in this problem is

(-5a^2)^3\cdot a^5

First of all, we proceed by evaluating the power of the term in the brackets. We apply the rule:

(a^m)^n=a^{m\cdot n}

So

(a^2)^3=a^6

Moreover, we have

(-5)^3=-125

Therefore,

(-5a^2)^3=-125 a^6

So now the expression is

-125a^6 \cdot a^5

Now we apply the following rule:

a^m \cdot a^n = a^{m+n}

So we have

a^6\cdot a^5 = a^{6+5}=a^{11}

Therefore, our expression becomes:

-125a^6\cdot a^5=-125a^{11}

Find the equation of the line parallel to the line y = 2x + 3 and expect oy in (0; 1)
nignag [31]

Step-by-step explanation:

Any lines that are parallel to each other have the same slope (coefficient of x is the same)

In this case, y = 2x + c.

Since it includes the point (0, 1), the y-intercept is 1 and that is c itself.

Hence, the equation of the parallel line is y = 2x + 1.

Simplify the expression (4x − 3)(x + 5). 4x2 − 17x + 15 4x2 − 17x − 15 4x2 + 17x + 15 4x2 + 17x − 15
DanielleElmas [232]
There are mnemonic acronyms out there for reminding you how to do this. I think of it simply as using the distributive property.
  (4x-3)(x+5) = 4x(x+5) -3(x+5)
then again
  = (4x² +20x) + (-3x -15)
  = 4x² + (20-3)x -15 . . . . . . . combine like terms
  = 4x² +17x -15

Solve 2(3x+6)=3(x-9) 2p-3=3p+2 2(3x-1)-7(5x+4)=9(2x-3)
earnstyle [38]

Answer:

Step-by-step explanation:

1. 6x + 12 = 3x - 27

   3x + 12 = -27

   3x = -39

    x = -13

2. 2p - 3 = 3p + 2

    -p - 3 = 2

     -p = 5

      p = -5

3. 6x - 2 - 35x -28 = 18x - 27

   -29x - 30 = 18x - 27

   -47x - 30 = -27

    -47x = 3

    x = -3/47
