π ∫₀¹ x² dx
This integral is obtained using disk method. Each disk has a volume of V = πr²t, so the radius is r = x.
The region is 0 ≤ y ≤ x, 0 ≤ x ≤ 1.
Revolved around the x-axis, the resulting shape is a cone.
If the shape were a paraboloid, the integral would have been:
π ∫₀¹ (x²)² dx
π ∫₀¹ x⁴ dx
Find the value of x for which the lines rand s are parallel.
Answer:
x = 12
Step-by-step explanation:
<1 and the 142-deg angle are vertical, so m<1 = 142 deg
The angle measuring 3x + 2 and <1 are same-side interior angles. If the lines are parallel, then those two angles are supplementary.
3x + 2 + 142 = 180
3x + 144 = 180
3x = 36
x = 12

Write the equation of a line that is parallel to 4x-2y=3 and is passing through the point (2,1)
Answer:
y= 2x -3
Step-by-step explanation:
Let's rewrite the given equation into the form of y=mx+c, so that we can find the gradient of the line. In this form, m (coefficient of x) is the gradient.
4x -2y= 3
2y= 4x -3
Divide by 2 throughout:
[tex]y = 2x - 1 \frac{1}{2} [/tex]
Thus the gradient is 2.
Parallel lines have the same gradient thus the line would also have a gradient of 2.
Substitute m=2 into the equation:
y= 2x +c
To find the value of c, substitute a pair of coordinates.
When x=2, y=1,
1= 2(2) +c
1= 4 +c
c= 1 -4
c= -3
Thus, the equation of the line is y= 2x -3.

6. Mary and Steve each travel 845 miles. Mary drove an average of 5 mph faster than Steve and completed the trip in one hour's less time
than Steve. What was each person's average speed?
Answer:
Steve had an average speed of 62.55 mph while Mary had an average speed of 67.55 mph
Step-by-step explanation:
Here, we want to calculate the average speed of each of the two.
From the question, we are told that Mary drove an average of 5 mph faster than steve.
So, let the average speed of Steve be x mph, this means that the average speed of Mary will be (x + 5) mph
Mathematically;
Time = distance/speed
Time taken by Steve = 845/x hours
Time taken by Mary = 845/(x + 5)
But Mary took an hour less to complete her own trip;
This means that;
if we add one hour to the time spent by Mary, then we will have the time spent by Steve
845/(x + 5) + 1 = 845/x
845/(x + 5) = 845/x -1
845/(x + 5) = (845 - x)/x
Cross multiply;
845(x) = (x + 5)(845-x)
845x = x(845-x) + 5(845-x)
845x = 845x-x^2 + 4225 - 5x
x^2 + 5x - 4225 = 0
We can solve this using the quadratic formula;
x = -b ± √(b^2 - 4ac)/2a
where a = 1 , b = 5 , c = -4225
x = -5 ± √(5^2 - 4(1)(-4225)/2(1)
x = -5 ± √(25 + 16,900)/2
x = -5 ± √(16,925)/2
x = (-5 + 130.1)/2 or (-5-130.1)/2
We ignore the negative side as speed cannot be negative
x = (-5 + 130.1)/2 = 62.548 which is approximately 62.55 mph
So steve’s speed is 62.55 mph while Mary’s speed = 62.55 + 5 = 67.55 mph
The femur or thigh bone of an average human is 480 millimeters long. The spinal cord of an average human is 45 centimeters long. What is the total length of a spinal cord and a femur in meters
PLEASE NEED HELP
Answer:
0.93m
Step-by-step explanation:
Convert 480 mm to m
480mm x (1m/1000mm) = 0.48m
Convert 45 cm to m
45cm x (1m/100cm) = 0.45m
Add the two numbers up
0.48m + 0.45 m = 0.93 m
A remote ranch has a cylindrical water storage tank. It has a vertical central axis, a diameter of 16 ft, the sides are 5 ft high, and it is full to the brim. The depth of this water is 4 ft. How much work (in ft-lb) would be required to pump all of the water over the upper rim? (Use the fact that water weighs 62.5 lb/ft3. Round your answer to the nearest integer.)
Answer and Step-by-step explanation:
Given: diameter = 16ft height = 5 ft. Depth = 4ft
Work =?
As we know that work = force x distance
W= distance x density x volume
W= ʃ04 (5-y) 62.5x ∏ (d/2)2dy (area = ∏r2 , r= d/2)
= 62.5 ʃ04 (5-y) ∏ (4y) dy
=62.5∏ ʃ04 (5-y) 4ydy
=62.5∏ ʃ04 20y-4y2dy
=62.5∏ |20y2/2 – 4y3/3|04
=62.5∏ |74.66|
=14659ft.lbs (approximately)
The work (in ft-lb) that would be required to pump all of the water over the upper rim is :
Given: Diameter = 16ft Height = 5 ft. Depth = 4ftWork =?
Formula:work = force x distance
W= distance x density x volume
W= ʃ04 (5-y) 62.5x ∏ (d/2)2dy (area = ∏r2 , r= d/2)
W = 62.5 ʃ04 (5-y) ∏ (4y) dy
W =62.5∏ ʃ04 (5-y) 4ydy
W =62.5∏ ʃ04 20y-4y2dy
W =62.5∏ |20y2/2 – 4y3/3|04
W =62.5∏ |74.66|
W =14659ft.lbs (approximately)
The work (in ft-lb) that would be required to pump all of the water over the upper rim is 14659ft.lbs

What is the length of the arc subtended by the angle measuring 4 radians?
A.
4 cm
B.
2 cm
C
16 cm
D
8 cm
Answer:
D. 8 cm
Step-by-step explanation:
Given :
Let the length of the arc be = l
radius of the arc, r = 2 cm
degree of angle subtended at the center by the arc, θ = 4 radian
Now we know that the angle subtended by an arc at the center of the circle whose radius is 2 cm will be,
θ = l/r
Therefore, we can write,
l = θ x r
l = 4 x 2
= 8 cm
So the length of the arc is 8 cm.
