Answers
Answer:
[tex]17-\frac{6}{5}j[/tex]
Step-by-step explanation:
The first step is to combine like terms. 16 - 4 = 12 + 5 = 17 and [tex]-\frac{2}{5}j - \frac{4}{5}j[/tex] = [tex]-\frac{6}{5}[/tex]j
Now combine those two to get 17 [tex]-\frac{6}{5}[/tex]j

3x+2y=5 from.a given equation, find two points that will satisfy the equation
Answers
Answer:
(0,2.5) and (1,1)
Step-by-step explanation:
Given
[tex]3x + 2y = 5[/tex]
Required
Determine the points that satisfy the equation
To do this, we substitute values for x and y in the equation.
Let x = 1
Substitute 1 for x in [tex]3x + 2y = 5[/tex]
[tex]3(1) + 2y = 5[/tex]
[tex]3 + 2y = 5[/tex]
Make 2y the subject
[tex]2y = 5 - 3[/tex]
[tex]2y = 2[/tex]
Solve for y
[tex]y = 1[/tex]
Hence, a point is: (1,1)
To determine another point, take x as 0
Substitute 0 for x in [tex]3x + 2y = 5[/tex]
[tex]3(0) + 2y = 5[/tex]
[tex]0 + 2y = 5[/tex]
[tex]2y = 5[/tex]
Solve for y
[tex]y = \frac{5}{2}[/tex]
[tex]y = 2.5[/tex]
Hence, another point is (0,2.5)
The length of a rectangle is 7 cm more than its width. If the diagonal of
the rectangle is 35 cm, find the dimensions of the rectangle.
What is the width an length ?
Answers
Answer:
Length = 12, width = 5
Step-by-step explanation:
The diagonal is the hypotenuse of a rectangular triangle.
Equation: d^2 = l^2 + w^2
35^2 = (x + 7)^2 + x^2
169 = (x + 7)(x + 7) + x^2
169 = x^2 + 7x + 7x + 49 + x^2
169 = 2x^2 + 14x + 49
subtract 169 from both sides
0 = 2x^2 + 14x - 120
divide by 2
0 = x^2 + 7x - 60
factor, to find the numbers just think of what number multiplied by what number would equal -60 and have the same numbers added together equals 7. 12 times 5 is 60 but it has to be -60, and 12 - 5 equals 7 so the numbers would be 12 and -5
0 = (x + 12)(x -5)
x = -12, and x = 5, but u can only use positive solutions so length equals 12 and width is 5
How do you do this question?
Answers
Answer:
a. 42%
b. 16%
Step-by-step explanation:
a. According to the curve, the bottom 80% of families has about 58% of the income, so the top 20% has about 42%.
b. The bottom 60% of families have about 32% of the income, and the bottom 40% of families have about 16% of the income. So the third quintile has about 32% − 16% = 16%.

LCM of a2+b2 and a4-b4
Answers
Answer:
The LCM is:
[tex](a^2+b^2)(a+b)(a-b)[/tex]
Step-by-step explanation:
Given polynomials are:
[tex]a^2+b^2\\a^4 - b^4[/tex]
We can use factorization to find the LCM of the given polynomials.
Taking the second polynomial, using the identity
[tex]a^2 - b^2 = (a+b)(a-b)[/tex]
Applying on 2nd polynomial
[tex](a^2)^2-(b^2)^2\\=(a^2+b^2)(a^2-b^2)\\=(a^2+b^2)(a+b)(a-b)[/tex]
We can see that [tex]a^2+b^2[/tex] is common in both polynomials, it will be counted only one time. The LCM of given polynomials is:
[tex](a^2+b^2)(a+b)(a-b)[/tex]
