It's inverse variationSee
3 contractors took 8hours
4 contractors took 6hours
We observe
No of contracter increases hence time decreasesSo it's inverse variation
Answer:
[tex]\fbox {Yes}[/tex]
Step-by-step explanation:
An inverse variation can be seen when two factors are compared, if one factor is seen to be increasing, then naturally the factor should be decreasing.
Here, as the number of contractors increase, the time taken to complete the work decreases.
∴ Hence, this represents an inverse variation.

Answer:
The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree

D or 8sqrt3
Step-by-step explanation:
the shortest side = the longest divided by 2
the shortest side = 16/2
the shortest side = 8
the longer side = the shortest times sqrt3
the longer side = 8 times sqrt3
the longer side = 8sqrt3

Answers
Answer:
a = 139.1
b = 56.2
Step-by-step explanation:
A. Reference angle = 68°
Opp = a
Hyp = 150
Therefore:
Sin 68 = opp/hyp
Sin 68 = a/150
150*sin 68 = a
a = 139.1 (nearest tenth)
B. Reference angle = 68°
Adj = b
Hyp = 150
Therefore:
Cos 68 = adj/hyp
Cos 68 = b/150
150*cos 68 = b
b = 56.2 (nearest tenth)

Answers
Answer: Long-term Liability
Step-by-step explanation:
This question relates to the classification of the lease above in accounting.
A long term liability is a payment that is owed by a company for a period lasting more than a year.
When a lease is for more than a year as is the case here, you take the present value of the lease and consider that amount to be a long term liability because it would represent an amount that the company is to pay for more than a single period.,

Construct a parallelogram whose diagonals
are 5.4 cm and 6.2 cm and an angle between
them is 70°.
Answers
Answer:
15.73 cm²
Step-by-step explanation:
Construct a parallelogram whose diagonals are 5.4 cm and 6.2 cm and an angle between them is 70°.
To construct the parallelogram, we find the Area of the parallelogram.
Area of a parallelogram = ½ × d1 × d2 × sin (y)
Where
d1 = Diagonal 1 = 5.4 cm
d2 = Diagonal 2 = 6.2 cm
y = Angle between them = 70°
Area of the parallelogram =
1/2 × 5.4 × 6.2 × sin 70
= 15.730454472 cm²
Approximately = 15.73 cm²

√48 = √(4²×3) = √4² √3 = 4√3 = 6.93
√12 = √(2²×3) = √2² √3 = 2√3 = 3.46
√125 = √(5²×3) = √5² √3 = 5√3 = 11.18
√28 = √(2²×7) = √2² √7 = 2√7 = 5.29
√75 = 5√3 = 8.66
√48 = 4√3 = 6.93
√12 = 2√3 = 3.46
√125 = 5√5 = 11.18
√28 = 2√7 = 5.29

What is the complete factorization of the polynomial below?
x^3- 2x²+x-2
A. (x-2)(x + 1)(x - 1)
B. (x + 2)(x + 1)(x - 1)
C. (x + 2)(x - 1)(x - 1)
D. (x-2)(x - 1)(x - 1)
Answers
Answer:
Let's start by rearranging this polynomial.
x^3 - 2x^2 + x - 2
x^3 + x - 2x^2 - 2
Now, factor out the common terms in the first two terms, and the second t wo terms. So we have: x(x^2 + 1) - 2(x^2 +1)
Apply the distributive property, and you have: (x-2)(x^2+1), which can't be factored further.
There's definitely something wrong with the answer choices here, or the problem itself.
Hopefully this helps!
The complete factorization of the polynomial is,
⇒ (x + i) (x - i) (x - 2)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The polynomial is,
⇒ x³ - 2x² + x - 2
Now, We can factor the polynomials as;
The polynomial is,
⇒ x³ - 2x² + x - 2
⇒ x² (x - 2) + 1 (x - 2)
⇒ (x² + 1) (x - 2)
⇒ (x + i) (x - i) (x - 2)
Therefore, The complete factorization of the polynomial is,
⇒ (x + i) (x - i) (x - 2)
