-21x^3 - 8x^3 = -29x^3
-7/4x^(1/2) - 0 = -7/4x^(1/2)
-6x^(1/4)
-12x^(-1/2)
12x^(-1/4)
14x^4

Therefore, the correct option is the 2nd one.

What is the distance between the points (7 , -2) and (7 , 8) in the coordinate plane?

sp2606 [1]

Answer:

10 units

Step-by-step explanation:

We are given two points on a plane;

(7 , -2) and (7 , 8)

We are supposed to determine the distance between the two points;

To get the distance between two points on a plane, we should use modulus formula;

Modulus = $\sqrt{(x_2-x_1)^2+(y_1-y_2)^2}$

Therefore, in this case;

Distance = $\sqrt{(8--2)^2+(7-7)^2}$

$=\sqrt{100+0}$

$=\sqrt{100} \\=10$

Therefore, the distance between the two points is 10 units.

Trapezoid ABCD has vertices A(2, 4) , B(5, 4) , C(7, 1) , and D(0, 1) . Is this trapezoid an isosceles trapezoid?

damaskus [11]

Answer:

Yes

Step-by-step explanation:

Segments AB and CD are parallel and 3 units apart.

Point D is 2 units left of point A, and point C is 2 units right of point B. The trapezoid is symmetrical about the line x = 3.5, so is isosceles.
