Dimtry bought a pair of pants at the discounted price of $30. The original price of the pants was $40. What was the percent of the discount? PLEASE EXPLAIN TO ME HOW YOU GOT YOUR ANSWER

Answers

Answer 1

Answer:

Answer:

25%

Step-by-step explanation:

Say we start from the beginning with $40. If the pants are discounted but we don't know the percent discount, then we need a variable, x:

40 - x% * 40 = 30

The total is 40. When we take a discount off of 40, we are taking a percent of 40 and subtracting that from 40. From the problem, this should be 30. Thus, the equation above.

Add x%*40 to both sides and subtract 30 from both sides:

x%*40 = 10

Divide by 40:

x% = 1/4 = 0.25

Multiply each side by 100:

x = 25

The answer is 25%.

Find a polynomial function P(x) if least degree with zeroes 7 and -2i. Write your final answer in expanded form complete with function name P(x).

Answers

1) Polynomial with complex coefficients wil be

$P(x)=(x-7)(x-(-2i))=(x-7)(x+2i)=x^2+2ix-7x-14i=\n \n=x^2+(2i-7)x-14i.$

2) Polynomial with real coefficients will be

$P(x)=(x-7)(x-(-2i))(x-2i)=(x-7)(x+2i)(x-2i)=(x-7)(x^2-(2i)^2)=\n \n=(x-7)(x^2-4i^2)=(x-7)(x^2+4)=x^3-7x^2+4x-28.$

B. 9 cm, 14 cm, 17 cm
C. 7 cm, 17 cm, 24 cm
D. 5 cm, 12 cm, 13 cm

Answers

Conditions for side lenghts for triangle:
a<b+c and
b<c+a and
c<a+b
so we check all posibilities:
A) 2+5=7 we can see that one condition is not fulfilled so they can't be side lenghts of triangle
B) 9<14+17
14<9+17
17<14+19
All conditions are fulfilled so they can be side lenghts of triangle
C)7<17+24
17<7+24
24<17+7
All conditions are fulfilled so they can be side lenghts of triangle
D)5<12+13
12<5+13
13<5+12
All conditions are fulfilled so they can be side lenghts of triangle
