The nature of the roots of the quadratic equation 4x² - 5x + 3 is complex.
What is a polynomial?Polynomial is an equation written as the sum of terms of the form kx^n.
where k and n are positive integers.
We have,
4x² - 5x + 3
This is in the form of ax² + bx + c
a = 4
b = -5
c = 3
Now,
D = b² - 4ac
If D < 0 there will be complex roots.
Now,
D = (-5)² - 4 x 4 x 3 = 25 - 48 = -23
D < 0
This means,
The roots are complex.
Thus,
The equation has complex roots.

A sheet of paper has a perimeter of 39 inches. If the width of the paper is 8.5
inches, what is the length of the sheet of paper?
Answer:
length of the sheet of paper is 11 in.
Step-by-step explanation:
Let "a" = short end of paper and let "b" = long end of paper.
Let "p" = perimeter
1st equation: p = 39"
2nd equation: 2a + 2b = p plug in "39" for diameter; result:
2nd equation: 2a + 2b = 39
3rd equation: b = 2a - 6
replace "b" in 2nd equation with "2a - 6" from 3rd equation, result:
2a + 2(2a - 6) = 39 simplified to:
2a + 4a - 12 = 39 simplified to:
6a - 12 = 39 simplified to:
6a = 51 simplified to:
a = 51/6 = 8.5
so, a = short end of paper = 8.5 inches
In 3rd equation (b = 2a - 6), substitute "a" with "8.5"
3rd equation becomes: b = 2(8.5) - 6 simplified to:
b = 17 - 6 = 11
so, b = long end of paper = 11 inches
answer to question is: dimensions of paper are ---
8.5 inches wide by 11 inches long
Answer:
The answer is 11
Step-by-step explanation:
So perimeter is base+ base+length+length. Therefore you take 8.5+8.5 which is 17 and subtract it from 39 to get 22. You take 22 and divide it by 2 which leaves you with 11.

The price of television is P15,000 less than the twice the price of old model.If it cost P29,078.00 to buy a new television.What is the price of the old model?
Answer:
P22039
Step-by-step explanation:
Cost of new television = 29078
Let the price of old model television = x
2x - 15000 = 29078
2x = 29078 + 15000
2x = 44078
2x/2 = 44078 /2
x = 22039
Hence, price of old model television is P22039
Jed wants to earn 25% annual net income on his $50,000 cash investment in property his annual expense of owning the property are $9600 what monthly rent must jed charge
Answer: $1,842
Step-by-step explanation:
John wants to earn 25% of his investment of $50,000 which is:
= 25% * 50,000
= $12,500
He has expenses of $9,600 yearly so the rent he should charge per year in order to make his 25% requirement as income is:
= Expenses + Return
= 9,600 + 12,500
= $22,100
Rent per month is:
= 22,100 / 12
= $1,842

The 34th term of the arithmetic value progression is a₃₄ = 229
What is Arithmetic Progression?An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the sequence be represented as A
Now , the value of A is
A = {-2,5,12,19...}
And , to find the 34th term of the sequence {-2, 5, 12, 19, ...}, we first need to find the common difference between consecutive terms:
The common difference = 5 - (-2) = 7
So, to get the 34th term, we can use the formula for the nth term of an arithmetic sequence:
an = a1 + (n-1)d
where a1 is the first term, d is the common difference, and n is the term number we want to find.
Plugging in the values we have:
a₃₄ = -2 + (34-1)7
a₃₄ = -2 + 231
a₃₄ = 229
Hence , the 34th term of the sequence is 229

Find the Are of the Shaded Region
Answer:
≈ 84.8 cm²
Step-by-step explanation:
The area of the shaded region is calculated as
area of circle - area of unshaded sector
area of circle = πr² = π × 6² = 36π
unshaded area = area of circle × fraction of circle
= 36π × [tex]\frac{90}{360}[/tex] = 36π × [tex]\frac{1}{4}[/tex] = 9π
area of shaded region = 36π - 9π = 27π ≈ 84.8 cm² ( nearest tenth )
