[tex]15 \% \: of \: 60 \\ \\ = \frac{15}{100} \times 60 \\ \\ = \frac{900}{100} \\ \\ = 9[/tex]

Step-by-step explanation:  The prime factorization of  4320   is

  2•2•2•2•2•3•3•3•5  

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 4320   =  √ 2•2•2•2•2•3•3•3•5   =2•2•3•√ 30   =

               ±  12 • √ 30

 √ 30   , rounded to 4 decimal digits, is   5.4772

So now we are looking at:

          w  =  ( -40 ± 12 •  5.477 ) / -34

Two real solutions:

w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757

or:

w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110

Answer:

How you solve it is you pick two points on a line and figure out their coordinates. Determine the difference in the y-coordinates of those two points. Then you also do the same thing with the x-coordinates. Then you divide the difference in the Y and X coordinates .

Answer:

  B.  3x^2 +11x -20 = 0

Step-by-step explanation:

For solutions p and q, the quadratic will be

  (x -p)(x -q) = 0

We notice that the leading coefficients of the offered answer choices are greater than 1, so it will be convenient to use a value that "clears fractions."

  (x -4/3)(x -(-5)) = 0

  3(x -4/3)(x +5) = 0 . . . . multiply by 3 to clear the fraction

  (3x -4)(x +5) = 0 . . . . . . clear the fraction

  3x(x +5) -4(x +5) = 0 . . use the distributive property

  3x^2 +15x -4x -20 = 0 . . . . use the distributive property again

  3x^2 +11x -20 = 0 . . . . collect terms

_____

The constant in the product of factors is the product of roots:

  (x -p)(x -q) = x^2 -(p+q)x +pq

Here, that would mean the constant would be (4/3)(-5) = -20/3.

If we compare the above quadratic to the standard form:

  ax^2 +bx +c = 0

we find that we can divide the standard form equation by 'a' to get ...

  pq = c/a

That is, c/a = -20/3, so we might start looking for an answer choice that has a leading coefficient of a=3 and a constant of c=-20.

Answer:

-4/27

Step-by-step explanation:

first write -4 1/2 as a fraction, which is -9/2. Then you divide by 1/3:

-9/2 / 2/3=

-2/9 * 2/3 =

-4/27

Answer: A) 2 1/12 yards

B) 13/24 yards

Step-by-step explanation: A)

1 3/4 = 7/4 + 1/3 =

7/4(3/3) + 1/3(4/4)=

21/12 + 4/12 = 25/12 = 2 1/12 yards

B)

7/8 - 1/3 =

7/8(3/3) + 1/3(8/8)=

21/24 - 8/24 = 13/24 yards

Answer:

(3 1/2, -1)

Step-by-step explanation:

Answer:

The answer is 30 degrees

Step-by-step explanation:

the total of all three angles in a triangle add up to 180.

50+100= 150

so,

180-150= 30

x= 30 degrees

hope this helps!!

Answer:

answer is B 30

Step-by-step explanation:

180 is the total degrees of the whole thing subtract both angels they already give you (100+50) that leaves you with 30

Answer:

2x + 8

Step-by-step explanation:

Let x be that number:

2x + 8

Answer: the area of the resulting surface is π/16 [ 4√(17)  + In( 4 + √( 17)) ]

Step-by-step explanation:

Given that;

y = e^(-4x),  x ≥ 0

then, dy/dx = -4e^(-4x)

now, √( 1 + (dy/dx)² ) = √( 1 + ( -4e^(-4x))²) = √( 1 + 16e^(-8x)

so the surface area of the surface obtaining by rotating the curve y = e^(-4x) on ( 0, ∞ ) about x-axis is,

S = ₀∫^∞ 2πy √( 1 + (dy/dx)² )  dx

S = ₀∫^∞ 2πe^(-4x) . √( 1 + 16e^(-8x) dx

S = 2π. ₀∫^∞ e^(-4x) . √( 1 + 16e^(-8x) dx

so LET 4e^-4x = u ⇒  -16e^(-4x) dx = du

⇒e^-4x dx = du/ -16

so whenx = 0, then u =4 and when x → ∞ then e^(-4x) → 0 so u →0

therefore

S = 2π ₄∫⁰ √(1 + u²) . du/-16

= π/8 ₀∫⁴ √(1 + u²) . du

= π/8 [ u/2√(1 + u²)  + 1/2 In ( u + √( 1 + u²) ]₀⁴

WE MAKE USE OF

∫√( a² + u²) du = u/2√(a² + u²) + a²/2 In ( u + √( a² + u²)) + C

so

= π/8 [ 4/2√(1 + 16)  + 1/2 In ( 4 + √( 1 + u16 ]

= π/8 [ 2√(17)  + 1/2 In ( 4 + √( 17)) ]

= π/16 [ 4√(17)  + In( 4 + √( 17)) ]

therefore the area of the resulting surface is π/16 [ 4√(17)  + In( 4 + √( 17)) ]

Answer:

Step-by-step explanation:

There is nothing to indicate the graph is not of a polynomial function. Its zeros are the x=intercepts: -2, 3, 5. There are 3 of them, so that is the least degree the polynomial might have.

The expression x³ + 2x represents the sum of the cube of a number and two times the number "x."

"the sum of the cube of a number and two times the number."

Let "x" represent the unknown number.

Express the given in algebra form as x³ + 2x.

To calculate the value of this expression for a specific value of "x," substitute the value of "x" into the expression.

Cube the number by raising it to the power of 3 (x³).

Multiply the number by 2 (2x).

Add the results

expression x³ + 2x represents the sum.
