Answer:

Here's what I get

Step-by-step explanation:

Let the plane T be the xy-plane.

Points P, Q, and W are collinear but not coplanar with T.

It is possible for any of P, Q, and W to be on T. I have shown Q as a point on T.

If the lengths of PQ and PW are given, you can determine the length of QW.

PQ + QW = PW

QW = PW - PQ

Answer:

Step-by-step explanation:

Given that a plane T is there and 3 collinear points P,Q,W are there.

Part A;

PQW line lies has infinite points, , There is a chance that any one will be a point on the plane.

Part B) Since PQW are collinear

We find that PQ+QW = PW

Hence if PQ and QW are known we can easily find PW>

Đơn giản các biểu thức logic: a- p ∧ (p ∨¬q) ∧ (¬p ∨ ¬q)

creativ13 [48]

I can't conveniently copy the logical symbols you use, so I write

AND = ∧ (conjunction)

OR = ∨ (disjunction)

NOT = ¬

Tautologically,

p = (p AND q) OR (p AND NOT q)

and we can distribute the OR to get the equivalent statement

(p OR (p AND NOT q)) AND (q OR (p AND NOT q))

and again to get

((p OR p) AND (p OR NOT q)) AND ((p OR q) AND (q OR NOT q))

Now, q OR NOT q is always true, and p OR p is simply p, so we have

p = p AND (p OR q) AND (p OR NOT q)

This shows that p OR NOT q is already included in p, so our initial statement is simply

p AND (NOT p OR NOT q)

Distributing the conjunction, we get

(p AND NOT p) OR (p AND NOT q)

p AND NOT p is tautologically false, but we're considering a disjunction, so the truth value of p AND NOT q is the only value that's relevant. So, the initial statement collapses to

p AND NOT q

Show the steps you used to solve 4x + 2y = 8 5x - 3y = 4

Mekhanik [1.2K]

Answer:

-0.2

Step-by-step explanation:

Simplifying

5x = 3y + -4

Reorder the terms:

5x = -4 + 3y

Solving

5x = -4 + 3y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '5'.

x = -0.8 + 0.6y

Simplifying

x = -0.8 + 0.6y

Amir buys a new car for £16470. The value of the car will depreciate by 2% each year. Work out how much amir's car will cost aft

Ronch [10]

Answer:

Amir's car will cost £10348.88 after 23 years.

Step-by-step explanation:

I finally found a UK human!

This is compound interest so you have to find a decimal multiplier and multiply that with £16470 to the power of 23.

The decimal multiplier would be 0.98. This is because you do 100% - 2% as depreciating basically means a decrease, which gives you 98% and then you divide that by 100 to get your decimal multiplier - 0.98.

16470 × $0.98^{23}$ = £10348.88
