Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15

<em><u>Solution:</u></em>

The function that models the yield is:

f(x) = -x^2 + 20x + 75

The average rate of change of f(x) from x = a to x = b is given by the formula:

\text{ average rate of change }=\frac{f(b)-f(a)}{b-a}

Find and interpret the average rate of change from year 5 to year 15

f(5) = -(5)^2 + 20(5) + 75\\\\f(5) = -25 + 100 + 75\\\\f(5) = 150

f(15) = - (15)^2 + 20(15) + 75\\\\f(15) = -225 + 300 + 75\\\\f(15) = 150

<em><u>Thus average rate of change:</u></em>

\text {average rate of change}=\frac{f(15)-f(5)}{15-5}

\text {average rate of change}=\frac{150-150}{10}=0

Thus Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15.

Hey There!

Lets Just Work through your answers,

ⓧ A - An isosceles triangle is a triangle with (at least) two equal sides, so this would not apply to the given triangle.

:) B - A scalene triangle is a triangle in which all three sides have different lengths so this applies to the given triangle. One side measures 10, one measures 11, and one measures 12.1

ⓧ C - A right triangle is a type of triangle that has one angle that measures 90 degrees, which this triangle does not so this does not apply.

ⓧ D - In geometry, an equilateral triangle is a triangle in which all three sides are equal, so this does not apply to the given triangle.

ⓧ E - An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles, so this does not apply to the given triangle.

:) F - An acute triangle (or acute-angled triangle) is a triangle with three acute angles less than 90 degrees. So this applies to the given triangle.

In Summary, B & F classify the given triangle correctly.

If you could rate five starts & give brainliest that would be greatly appreciated!

Hope I helped, Have a good day.

Which of the following affects one's car insurance premium?
erica [24]

A car insurance premium is the amount of money a person pays for his insurance policy taken for his car or automobile. Usually, this depends on the age of the driver as the driver’s age can tell about his driving experience and accident risk. So, drivers with good experience or who are not very young have less insurance premiums than the younger ones.

As age is not given as any option and gender is given, so it can be the answer, But premiums are almost same for both the genders. Age is the correct factor that affects premiums.

Please help with this Geometry worksheet.
Marianna [84]

Answer:

1. x= 122(answer on pdf=n)

2. x=38(answer on pdf=s)

7. x=26(answer on pdf=l)

8. x=14(answer on pdf=p)

13. x=22(answer on pdf=b)

14. x=12(answer on pdf=k)

Step-by-step explanation:

Supplementary angle for number 1 so 58+x=180

180-58=x=122

Number 2 is a complimentary angle so 52+x=90

90-52=x=38

Number 7 is a complimentary angle so  64+x=90

90-64=x=26

Number 8 it states that the angles are equal so 4x=56

56/4=x=14

Number 13 is a supplementary angle so (6x-2)+50=180

(180-50+2)/6=x=22

132/6=x=22

Number 14 is complimentary so 8x-6=90

96/8=x=12
