Answer:
Step-by-step explanation:
The Midpoint formula is
where the x's and y's come from the coordinates of the endpoints. Filling in:
Answer:
he expression is undefined where the denominator equals
0
, the argument of an even indexed radical is less than
0
, or the argument of a logarithm is less than or equal to
0
.
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Step-by-step explanation:
Answer:
1 Degree
Step-by-step explanation:
A complementary angle measures 90 degrees in all. So if one angle is 89 degrees, then we need to subtract 89 by 90
90
- 89

Given:
The diameter of the wheel is 2 feet.
Number of revolution = 100
To find:
The total distance covered by the bicycle.
Solution:
The circumference of a circle is:
Where, r is the radius of the circle.
The diameter of the wheel is 2 feet. So, the radius of the circle is 1 feet.
Putting in the above formula, we get
It means the distance covered by the wheel in one revolution is 6.28 feet.
Number of revolution is 100. So, the total distance covered by the wheel in 100 revolution is:
The total distance covered by the bicycle in 100 revolution is 628 feet.
Therefore, the correct option is B.
Let the side of one square be x. Area = x*x = x²
Then the side of other square would be 2x , Area = 2x*2x = 4x²
Combined area = x² + 4x² = 5x²
This combined area = 45 cm²
Therefore 5x² = 45 Divide both sides by 5
x² = 45/5
x² = 9 Take square root of both sides
x = √9
x = 3
Length of larger square is 2x = 2*3 = 6 cm
Length of larger square = 6cm
