If he swan the length and the width of the pool it would be 21 x28 = 588 sq ft.
by swimming the length and the diagonal of the pool (25 ft) found that by using the pythagorean therom so now you are multiplying 21 x 25 = 525
588-525= 63 ft he is saving
The weight of the object is only dependent on the strength of gravity on that particular object.
Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Radius, r = 7 inches
θ = pi/4
2π = 360 degrees
180 degrees = π radians
1 radian = 180/π
2.1 radians = 2.1 × 180/π = 120.38 degrees
Therefore,
Length of arc = 120.38/360 × 2 × 3.14 × 7
Length of arc = 14.7 inches rounded up to 1 decimal places
The slope in the equation of a line is the coeffient of x
the equation of a line and a point is
(y-y1)=m(x-x1)
where m is the slope so 3 is the slope
