Answer:
2.2.1 Area = 12.6 cm²
2.2.2 Area = 12 cm²
Step-by-step explanation:
<u></u>
<u>2.2.1:</u>
The radius of the big circle is half the length of the square = 2.5 cm
The radius of the small circle is half of 3 cm = 1.5 cm
The area of the shaded portion is = Area of big circle - Area of small circle
π × 2.5²-π × 1.5² = 12.6 cm²
<u>2.2.2</u>
To find length BD (the height of the parallelogram) we need to use the Pythagorean theorem:
BD = √(5²-3²) = 4
Area = base x height = 3x4 = 12 cm²
Answer:
Option 1 and option 5.
Step-by-step explanation:
The given graph is a downward parabola. It means the value of function increases and after reaching its maximum point the value of function decreases.
Scenario 1 : The height of a stone shot by a catapult reaches a maximum height and then falls on the ground.
The graph of this scenario is a downward parabola. Therefore option 1 is correct.
Scenario 2 : The speed of a car increases constantly by 10 miles per hour.
The graph of this scenario is a straight line with slope 10. Therefore option 2 is incorrect.
Scenario 3 : The radioactivity of a substance decreases by 10% every year.
The graph of this scenario is an decreasing curve which represents an exponential function. Therefore option 3 is incorrect.
Scenario 4 : The amount of money in an account decreases for a few months and then increases.
The graph of this scenario is a upward parabola. Therefore option 4 is incorrect.
Scenario 5 : The sale of product increases at first and then decreases.
The graph of this scenario is a downward parabola. Therefore option 5 is correct.
Therefore, the correct options are 1 and 5.
x/8-11=15
Quotient means to divide. So, the question is asking you to divide a number and 8. Then, subtract it from 8 to get the answer 15.
