True or False?<br><br> If x∈ W, then x∈ Z
zepelin [54]

Answer:

False

Step-by-step explanation:

If W and Z are vector spaces, then no, that is not necessarily true. That's not generally true for any circumstance unless the vector space W is a subspace of Z, or vice versa.

A car radiator needs a 80% antifreeze solution. The radiator now holds 15 liters of a 70% solutions. How many liters of this sho
slavikrds [6]
So... the radiator has 15 liters of 70% antifreeze.. but needs an 80% antifreeze

well, so, you need to drain some and put some with higher percentage, seems to be, you will end up at the same 15 liters, possible the radiator's capacity, of 80% antifreeze

so, the same amount going out, of 70% is the same amount going in, of 100% antifreeze

now.. let's use the decimal format for the percents, or 70% is 70/100 or 0.7 and so on
\bf \begin{array}{lccclll}&#10;&amount&concentration&&#10;\begin{array}{llll}&#10;concentration\\&#10;amount&#10;\end{array}\\&#10;&-----&-------&-------\\&#10;\textit{70\% sol'n, out}&x&0.7&0.7x\\&#10;\textit{100\% sol'n, in}&x&1.00&x\\&#10;\textit{current 70\% sol'n}&15&0.7&10.5\\&#10;-----&-----&-------&-------\\&#10;mixture&15&0.8&12&#10;\end{array}

so.. let's subtract, from the current solution, 0.7x and add 1x or x, our antifreeze concentration amount, should be 12 though

10.5 - 0.7x + x = 12

solve for "x"

Use Greens Theorem to evaluate integral x^2ydx - xy^2dy, where C is 0 ≤ y ≤ √9-x^2 with counterclockwise orientation
Ratling [72]

Answer:

Step-by-step explanation:

a circle will satisfy the conditions of Green's Theorem since it is closed and simple.

Let's identify P and Q from the integral

P=x^2 y, and Q= xy^2

Now, using Green's theorem on the line integral gives,

\oint\limits_C {x^2ydx-xy^2dy } =\iint\limits_D {y^2-x^2} \, dA\\\\
