What does isolating variables mean??

leva [86]

Isolating variables mean to get the variable, or the letter all by itself by doing something to get rid of the number/numbers that are on the same side. That way you can solve for that missing variable.

Find the volume of a trapezoid with vertices at (2,0), (2,2), (4,0), and (4,4); about the x-axis.

mr Goodwill [35]

The trapezoid have vertices at (2,0), (2,2), (4,0), and (4,4)
and the rotation about the x-axis.
the points (2,0), (4,0) are located on the x-axis
calculate the function y = m x + c using the other vertices (2,2), (4,4)
by substituting in the function y
m = 1 , and c =0
∴ y = x

The volume can be calculated using
$V =\int\limits^a_b { \pi y^2 } \, dx$

∴ $V = \int\limits^4_2 { \pi y^2 } \, dx = \int\limits^4_2 { \pi x^2 } \, dx
$
∴ $V = \pi \ * \frac{x^3}{3} 
$
∴ $V = \frac{ \pi }{3} * (4^3-2^3)= \frac{56 \pi }{3}$

In angle PQR, angleQ=70 angle R=45 then angleP=.....

NemiM [27]

Answer:

Step-by-step explanation:

Because its a triangle,

P + Q + R = 180

So,

P + 70 + 45 = 180

P + 115 = 180

Subtract 115 on both sides

P = 65
