3. Let P, be the plane through the origin containing the vectors [1, 2, -1] and [0, 1, 1]. Let P2 be the plane through the point (1, 1, 1) parallel to the vectors (-1, 2, 2] and [3,4,-2].

(a) Find an equation for Pin normal form ax + by + cz = 0.

(b) The planes P, and P2 intersect in a line. Find a parametric equation for this line.

Let w=23 . what is the value of w + 45 ?

The amount of money, in dollars, in an account after t years is given by a = 1000(1.03)^t. the initial deposit into the account was $_^a0 and the interest rate was _a1% per year. only enter numbers in the boxes. do not include any commas or decimal points^t. the initial deposit into the account was $__^a0 and the interest rate is % per year.

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.
