0=x^2+29x+100

x= (-b +sqrt(b^2-4ac))/2a     x=(-b -sqrt(b^2-4ac))/2a

x=(-(29)+sqrt((29)^2-4(1)(100)))/2(1)      x=(-(29)+sqrt((29)^2+4(1)(100)))/2(1)

x=(-29+sqrt441)/2       x=(-29-sqrt441)/2

x=(-29+21)/2      x=(-29-21)/2

x=-8/2    x=-50/2

x= -4    x= -25

Find Simple Interest for the following scenario:
sashaice [31]

Answer:

Simple interest = $ 355,775

Explanation :

We have been given the following datas.

  • Principle amount = $53,500
  • Rate =13.3%
  • Time = 6 months

We have to find the simplest ratio of the given scenario.

  • Formula of Simple Interest = (P× R × T)/100

Simple Interest = (P× R × T)/100

Simple interest = $53,500 × 13.3 ×½

Simple Interest = $ 355775

Therefore, the required simple interest is $355775.

Using the distributive property to find the product (y - 4x)(y ^ 2 + 4y + 16) results in a polynomial of the form y ^ 3 + 4y ^ 2
galben [10]

Answer:

a=16

Step-by-step explanation:

The distributive property states that

a(b+c)=ab+ac

Therefore using the distributive property

(y - 4x)(y ^ 2 + 4y + 16)

=y(y ^ 2 + 4y + 16) - 4x(y ^ 2 + 4y + 16)

Expanding the brackets

y ^ 3 + 4y^2 + 16y - 4xy ^ 2 - 16xy - 64x.....(i)

Comparing with the form

y ^ 3 + 4y ^ 2 + ay - 4x  y ^ 2 - axy - 64x-----(ii)

The coefficient of y in (i) is 16 which corresponds to a and the likewise the coefficient of xy

Therefore, a=16

Please help 30 points
mihalych1998 [28]

Answer:

41

Step-by-step explanation:

40+16+y=180°

56+y=180°

y=180-56

y=124°

124+15+x=180°

139+x=180°

x=180-139

<em>x=41°</em>

If you buy a stock for $80 per share and sell it for $100 per share, what is the percent increase?
Tasya [4]

I think I might be wrong but try 25% (but like I said probably wrong)

80 / 100 = 1.25

100 - 80 = 20

So, 1.25 x 20 = 25%
