The table shows the relationship between the diameter in kilometers of an oil spill and the time in days. A quadratic function can be used to model this relationship.
What is the best prediction of the time required for the oil spill to reach the diameter of 10 km?
A) 147 days
B) 200 days
C) 205 days
D) 233 days
Answers
Answer:
205 is my answerrrrrrrrrrr
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 147 days. Then the correct option is A.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = y. Then the degree of the equation will be 2.
The table shows the connection between the width in kilometers of an oil slick and the time in days. A capability can be utilized to show this relationship.
The equation at (2.4, 1) will be given as,
2.4 = a (1)² + b (1) + c
2.4 = a + b + c ...1
The equation at (9.4, 2) will be given as,
9.4= a (2)² + b (2) + c
9.4 = 4a + 2b + c ...2
The equation at (21.1, 3) will be given as,
21.1 = a (3)² + b (3) + c
21.1 = 9a + 3b + c ...
Solve equations 1, 2, and 3 with the calculator, then we have
a = 2.35, b = -0.05, c = 0.1
Then the equation is given as,
y = 2.35x² - 0.05x + 0.1
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be
y = 2.35(10)² - 0.05(10) + 0.1
y = 235 - 0.5 + 0.1
y = 235.5
The value of y is nearer to the value of 233. Then the value of y will be 233 days.
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 233 days. Then the correct option is D.

The field produces 7200 kilograms of barley per hectare.
One hectare is 10000 m²,
Work out how many kilograms of barley the field produces.
Answers
Answer:
36,000 kg
Step-by-step explanation:
✔️First, find the area of the trapezium field:
Area of trapezium = ½(a + b)*h
Where,
a = 210 m
b = 190 m
h = 250 m
Area of trapezium = ½(210 + 190)*250
= ½(400)*250
= 200*250
= 50,000 m²
✔️Find the kg of barley that 50,000 m² field will produce:
10,000 m² (1 ha) produces 7,200 kg
Therefore,
50,000 m² will produce:
(50,000*7,200)/10,000
= 5*7,200
= 36,000 kg of barley

Angle 3 and 6 both equal 90 degrees. angle 1 is collinear with 6 and 5. Those three angles (1,6, and 5) add up to 180 degrees. If you subtract your angle 6(90) from 180 , you get 90 , then u subtract ur angle one(55) from 90 and get 35 degrees. I hope this makes sense, it’s harder to explain online

To find:
The common factors of given terms.
Solution:
We have,
[tex]4p^3mn^2[/tex] and [tex]2pm^2n^3[/tex]
The factor forms are
[tex]4p^3mn^2=2\times 2\times p\times p\times p\times m\times n\times n[/tex]
[tex]2pm^2n^3=2\times p\times m\times m\times n\times n\times n[/tex]
The common factors are 2, p, m, n, n. So,
Common factors = [tex]2\times p\times m\times n\times n[/tex]
= [tex]2pmn^2[/tex]
Therefore, the common factor of given terms is [tex]2pmn^2[/tex].

The ordered pair that represents how much she spends on a 5-day week is (20,25)
The rates are given as:
[tex]Access\ Roads = \$4[/tex]
[tex]Parking\ Lot= \$5[/tex]
From the question, x represents the access to roads, and y represents the number of days she parked her car.
So, her daily expense is:
[tex]Daily = Access\ Roads \times x + Parking\ Lot \times y[/tex]
This gives
[tex]Daily = 4\times x + 5\times y[/tex]
[tex]Daily = 4x + 5y[/tex]
For a 5-day work week, her daily expense is:
[tex]Daily = 4 \times 5 + 5 \times 5[/tex]
[tex]Daily = 20 + 25[/tex]
Express as ordered pair
[tex]Daily = (20 , 25)[/tex]
Hence, the ordered pair that represents how much she spends is (20,25)

Answer:
The relation is a function.
To analyze if the relationship shown is a function, you must observe that each value of the domain has a single value of the range assigned. For the given points {(-5, 6), (-2, 3), (3, 2), (6, 4)} this requirement is satisfied. Therefore, the relationship is a function.

Since there is one value of y for every value of x in ( − 5 , 6 ) , ( − 2 , 3 ), ( 3 , 2 ), ( 6 , 4 ) , this relation is a function.

Answers
Answer:

Step-by-step explanation:
When you round to the tens place you look at the number in the ones place. If it is 4 or less then you keep the tens place the same. If it's 5 or more then you round the tens place up one. Then you make the ones digit a 0.
Since there is a 2 in the ones place in 172, you keep the tens digit the same (170).
Since there is an 8 in the ones place in 18, you round the tens digit up one (20).
Now you multiply.
170×20=3400
