Q11.

Kamila [148]

Answer:

Step-by-step explanation:

The area of a trapezium is given as;

Area = $\frac{1}{2}$ (a + b)h

where: a is the length of the upper side, b is the length of its base and h is its height.

This implies that; a = x - 4, b = x + 5, h = 2x and area = 351

Thus,

351 = $\frac{1}{2}$ ((x - 4) + (x + 50)) 2x

= (x - 4 + x + 5) x

531 = (2x + 1) x

= 2 $x^{2}$ + x

So that;

2 $x^{2}$ + x - 531 = 0

This gives a quadratic equation.

Find the volume of the solid of revolution generated by revolving the region bounded by y = 2x^2, y = 0, and x = 2 about the x-a

Irina18 [472]

Answer:

$128 \pi/5 units^3$

Step-by-step explanation:

The volume of the solid revolution is expressed as;

$V = \int\limits^2_0 {\pi y^2} \, dx$

Given y = 2x²

y² = (2x²)²

y² = 4x⁴

Substitute into the formula

$V = \int\limits^2_0 {4\pi x^4} \, dx\\V =4\pi \int\limits^2_0 { x^4} \, dx\\V = 4 \pi [\frac{x^5}{5} ]\\$

Substituting the limits

$V = 4 \pi ([\frac{2^5}{5}] - [\frac{0^5}{5}])\\V = 4 \pi ([\frac{32}{5}] - 0)\\V = 128 \pi/5 units^3$

Hence the volume of the solid is $128 \pi/5 units^3$

One endpoint of a segment is (12, −8). the midpoint is (3, 18). find the coordinates of the other endpoint.

Lelu [443]

(-6,26) are the coordinates of the other endpoint because it it the same distance from the midpoint in the opposite direction of the other endpoint
